Hot-wiring the Transient Universe

Meeting Dates: 2019 Aug 19 - 22
Meeting Location: Evanston, IL
Registration deadline: 2019 June 24
Late Registration deadline: 2019 July 31

Hot-wiring the Transient Universe VI will explore opportunities and challenges of massively parallel time domain surveys coupled with rapid coordinated multi-wavelength follow-up observations.

The interdisciplinary agenda includes:

  1. Future and ongoing science investigations;
  2. Information infrastructure for publishing observations in real time;
  3. Novel data science to classify events and systems to optimize follow-up campaigns;
  4. Hands on activities to train on alerts from current surveys and broker systems.
Time domain astronomy is at the fore of modern astrophysics and crosses fields from solar physics and solar system objects, through stellar variability, to explosive phenomena at galactic and cosmological distances.

Recent rapid progress by instruments in space and on the ground has been toward a continuous record of the electromagnetic sky with ever increasing coverage, sensitivity, and temporal resolution. With the advent of gravitational wave and neutrino observatories we are witnessing the birth of multi-messenger astronomy.

See conference website for additional information.

Variable Galactic Gamma-Ray Sources (V)

Meeting Dates: 2019 Sep 4 - 6
Meeting Location: Barcelona, Spain

Active Galaxies and Quasars (dedicated to M. A. Arakelian's 90th anniversary)

Meeting Dates: 2019 Sep 9 - 10
Meeting Location: Byurakan, Armenia
Registration deadline: 2019 July 20

An International Conference "Active Galaxies and Quasars" will take place on Sep 9-10, 2019 in the Byurakan Astrophysical Observatory (BAO) dedicated to M. A. Arakelian's 90th anniversary. Prof. Arakelian (1929-1984) was one of the prominent Byurakan astronomers, the author of famous Arakelian galaxies, which at present are target for many-sided studies with ground-based and space telescopes. Arakelian is known as a distinguished specialist in the theoretical astrophysics and extragalactic astronomy.

Arakelian has compiled and published the Catalog of 621 high-surface-brightness galaxies, has proved the extragalactic origin of quasars, has determined the space density of extragalactic objects, has proposed several methods for study of properties of extragalactic objects, has made a comparative analysis of properties of different types of galaxies, and with his Russian colleagues spectroscopically has observed and studied some 800 faint galaxies and quasars. Arakelian galaxies have been observed in many observatories in the USA, UK, USSR, and elsewhere in optical wavelengths, radio and X-rays. Especially interesting objects are Akn 120 and Akn 564 (both are strongly variable AGN in X-ray and optical wavelengths; Akn 564 is a Narrow-Line Seyfert 1 galaxy that strongly changes the intensities of its emission lines).

BAO is one of the main observational centers of the former Soviet Union and is an important observatory with modern facilities in the region. It was founded in 1946 by one of the greatest astrophysicists of the 20th century V. A. Ambartsumian and is well known for its large spectroscopic surveys: First and Second Byurakan Surveys (FBS and SBS), undertaken by B. E. Markarian and his colleagues. BAO hosts a number of medium-size optical telescopes, the most important being the 2.6m classical telescope and 1m Schmidt telescope. BAO holds the Digitized First Byurakan Survey (DFBS, or the Digitized Markarian survey), containing low-dispersion spectra of ~20,000,000 objects, largest number in the world, which is the basis of the Armenian Virtual Observatory (ArVO), a member of the International Virtual Observatory Alliance (IVOA).

The registration fee is AMD 50,000 (equivalent to EUR 90), which includes Welcome Reception, all local transportation expenses, participants' kits, coffee breaks, and organizational expenses. We offer a number of travel grants for the participants from countries with limited travel funds. English is the working language of the conference.

Chandra/CIAO workshop

Meeting Dates: 2019 Sep 14 - 15
Meeting Location: Bologna , Italy
Abstract Deadline: 1 April 2019
Registration deadline: 31 July 2019

Are you new to Chandra data and the Chandra Interactive Analysis of Observations (CIAO) software? Are you an experienced CIAO user and would like to discuss advanced data analysis topics with CIAO experts?

Members of the Chandra X-Ray Center will host a two-day Chandra/CIAO workshop immediately following the the X-ray Astronomy 2019: Current Challenges and New Frontiers in the Next Decade conference on the week-end of Sep 14-15, 2019 in Bologna, Italy

This is the first time such a workshop is offered in Europe but plenty of information about previous CIAO workshops (including previous presentations) can be found on the CIAO workshop webpages. If you have any questions about the content of the workshop please contact the CXC Helpdesk.

The workshop will feature talks on introductory and advanced X-ray data analysis, statistics, and topics in Chandra calibration. The workshop will also include hands-on sessions where participants can practice X-ray data analysis following a workbook of CIAO exercises or perform their own analysis with members of the CIAO team ready to assist. Participants are required to bring their own laptop.

Students must register for the Chandra/CIAO workshop separately from the conference and they do not have to attend the X-ray meeting to attend the Chandra/CIAO workshop. The registration deadline is 31 July 2019. Please register as soon as possible since there must be a minimum number of registrants by that date for the workshop to occur. There is no cost to attend the Chandra/CIAO workshop, but registration is required.

For more information please visit the workshop website, or contact the CIAO Helpdesk with questions.

Compact White Dwarf Binaries Conference

Meeting Dates: 2019 Sep 15 - 21
Meeting Location: Yerevan, Armenia
Early registration deadline * : 2019 July 15

* Note: The meeting is limited to 100 participants, on the "first come first served basis".

Compact white dwarf binaries are formed when the more massive component in a stellar binary expands towards the end of its stellar life and engulfs its companion. This brief and dynamically violent common envelope phase shrinks the orbital separation, and results in a radically different evolution compared to single star evolution. Compact white dwarf binaries become interactive and lead to a variety of astrophysical important outcomes, including supernovae type Ia and low-frequency gravitational wave sources.

The goal of this conference is to bring together experts working across all areas related to compact white dwarf binaries, and to address the following key questions:

  1. What is the efficiency of common envelope evolution in extracting energy and angular momentum from binaries?
  2. What mechanisms drive the long-term evolution of compact binaries?
  3. Under what circumstances do white dwarfs grow in mass?
  4. How does accretion disc dynamics vary over the relevant parameters space, disc size and accretion rate?
  5. How does the presence of strong magnetic fields affect accretion physics?
  6. What are the properties of the Galactic population of ultracompact binaries, and what evolutionary paths produce them?
  7. The field of cataclysmic variables and related objects has seen transformational progress over the past decade, driven by new powerful instrumentation and large photometric time-domain and spectroscopic surveys.

The extragalactic explosive Universe: the new era of transient surveys and data-driven discovery

Meeting Dates: 2019 Sep 16 - 19
Meeting Location: Garching, Germany
Early registration deadline: 2019 July 31
Late registration deadline: 2019 Aug 31

At the turn of the decade, in 2010 a number of moderate-sized telescopes were equipped with digital cameras of around 10 square degrees. The relative cost of detectors and computing had reduced to a level where rapid, real-time processing of the imaging data provided monitoring of large sky areas every few days. This revolutionised the field of time domain astronomical surveys and we have witnessed a vast array of new discoveries. The global community have mapped the solar system, star forming regions in our galaxy, local group galaxies, and the local a nd high-redshift Universe leading to the discovery of new types of transients. We have discovered low luminosity stellar explosions in nearby galaxies and the most luminous supernovae beyond a redshift of 3, exotic transients in the nuclei of galaxies including tidal disruption events, stellar mergers, unusual novae and previously unknown species of stellar outbursts. The diversity in the explosive Universe is remarkable.

Type Ia supernovae have long been renowned for their homogeneity and use as standardisable candidates, but we now know thermonuclear supernovae show a wide diversity in explosion energies and composition of radioactive elements. How a white dwarf explodes, exactly what is the critical mass (Chandrasekhar or not), and what is the most common progenitor channel are all still unknowns. Explosions that we assume are from the core-collapse in massive stars are also stretching our understanding of how the explosion mechanism works. Many supernovae have explosion energies greater than a few times 1051 erg and are difficult to physically explain by neutrino driven core-collapse. The likely candidates are magnetar driven explosions, black hole and jet formation (as in GRBs), circumstellar interaction and pair-instability driven stellar deaths. Discoveries by revolutionary wide-field surveys such as the Palomar Transient Factory, Pan-STARRS, Catalina Sky Survey, La Silla QUEST, OGLE, Skymapper, Gaia, DES, ASAS-SN and ATLAS have changed the field. The extreme physics has come from rapid and detailed follow-up from X-ray to radio domains. ESO has played a major part in this through the swift reaction of the VLT and its extensive instruments combined with the Public ESO Survey of Transient Objects (PESSTO). Many of these surveys have now entered their second phase with upgraded detectors and even more ambitious goals.

These new data-driven initiatives are joined by the exciting prospect of routine detections of gravitational wave sources and electromagnetic follow-up. The spectacular discovery in August 2017 of the first merging neutron star system detected in gravitational waves and at almost every wavelength from gamma-rays to the radio has truly opened this new field. By September 2019, the third LIGO-Virgo run will have been running for 6 months and we may have new discoveries by the time of the meeting. The coming decade will have larger data sets that require public access for full scientific exploitation. The meeting will discuss how we will manage these large data sets. The conference will focus on the rich physics that has arisen from these discoveries and multi-wavelength follow-up programmes. Theory and modelling experts will also be a key part of the meeting, with a focus on how we can provide open data products to enhance model and data testing.

The 9th Fermi Symposium

Meeting Dates: 2020 March 29 - April 3
Meeting Location: Johannesburg, South Africa

This symposium follows previous Fermi Symposia at Stanford, CA (February 2007), Washington, DC (November 2009), Rome, Italy (May 2011), Monterey, CA (November 2012), Nagoya, Japan (October 2014), Arlington, VA (November 2015), Garmisch-Partenkirchen, Germany (October 2017), and Baltimore, MD (October 2018).

The two Fermi instruments have been surveying the high-energy sky since August 2008. The Large Area Telescope (LAT) has discovered more than a thousand new sources and many new source classes, bringing the importance of gamma-ray astrophysics to an ever-broadening community. The LAT catalog includes supernova remnants, pulsar wind nebulae, pulsars, binary systems, novae, several classes of active galaxies, starburst galaxies, normal galaxies, and a large number of unidentified sources. Continuous monitoring of the high-energy gamma-ray sky has uncovered numerous outbursts from a wide range of transients. Fermi LAT's study of diffuse gamma-ray emission in our galaxy revealed giant bubbles shining in gamma rays. The direct measurement of a harder-than-expected cosmic-ray electron spectrum may imply the presence of nearby cosmic-ray accelerators. LAT data have provided stringent constraints on new phenomena such as supersymmetric dark-matter annihilations as well as tests of fundamental physics. The Gamma-ray Burst Monitor (GBM) continues to be a prolific detector of gamma-ray transients: magnetars, solar flares, terrestrial gamma-ray flashes and gamma-ray bursts at keV to MeV energies, complementing the higher energy LAT observations of those sources in addition to providing valuable science return in their own right.

All gamma-ray data are made immediately available at the Fermi Science Support Center. These publicly available data and Fermi analysis tools have enabled a large number of important studies. We especially encourage guest investigators worldwide to participate in this symposium to share results and to learn about upcoming opportunities.

This meeting will focus on the new scientific investigations and results enabled by Fermi, the mission and instrument characteristics, future opportunities, and coordinated observations and analyses.
