Recent observations of interstellar regions of the Milky Way and of nearby galaxies, by the James Webb and Euclid space telescopes, have demonstrated the wealth of information that we can currently obtain on the InterStellar Medium (ISM) and on its intricate relation with star formation. We are entering an age where the amount and complexity of the data on the ISM calls for dedicated methods for processing observations, extracting the physical information they contain and comparing them to numerical simulations.

The present summer school will address the following outstanding questions.

• What are the new methods needed to analyze the data collected by modern observatories in our field?
• Which new concepts (observations, models) are required to bridge the remaining gap in angular resolution between the Milky Way and external galaxies?
• How can we apply our knowledge of the Galactic ISM to other galaxies? What are the limitations?
• How peculiar is the ISM of the Milky Way? How representative are nearby systems to understand the cosmic evolution of galaxies?

Galaxy assembly and evolution and the nature of the dark components of the Universe are some of the complex unresolved problems in today's cosmology. Ongoing and next-generation observations will provide us with unprecedented amount of data which will allow novel and complex statistical approaches. To be able to take that advantage, one has to be well versed in the processes happening on a wide range of scales from the formation of stars inside a galaxy to the shaping of the whole Cosmic Web itself.

Summer school "Large-scale structure of the Universe: from galaxies to cosmology" is dedicated to the topics related to galaxies and the Cosmic Web. Lectures will cover the theory for the cosmic web, mathematical modelling and computer simulations of cosmic web, also observations of cosmic web and its filiation with galaxies. The school is primarily intended for Doctoral students, however Master students and new Postdoctoral researchers are also welcome to apply.

For additional questions, please see the conference website.

The inaugural STScI JWST Summer School will focus on High-Redshift Transients with JWST. Early career scientists, new JWST researchers, and researchers new to the field are encouraged to join. The school will last two weeks: the first week will focus on high-z transients science, featuring lectures relevant to the field; the second week will focus on observational and analytical techniques, where participants will learn to create a JWST program and analyze and exploit JWST high-z transient data.

With its superb sensitivity and infrared capabilities, the James Webb Space Telescope (JWST) has opened a new and exciting window into Time Domain Astronomy (TDA) science, which was named a top priority for Astronomy and Astrophysics by the 2020 Decadal Survey. By detecting redder and fainter sources, JWST allows us to explore the early universe better and probe the epoch of reionization and first stars. It also provides insights into high-energy physics and explosion mechanisms. The year 2025 will see a wealth of new data relevant for TDA as the Rubin Telescope begins science, two new JWST data sets will be publicly available (COSMOS-3D and NEXUS), and JWST follow-up/Target of Opportunity proposals are expected to be submitted.

Registration will open soon. For more information please visit the webpage or contact the conference organizers: JWSTSummer2025[AT]stsci[DOT]edu
