Latest News COSMOS Field X-Ray & Far-IR Detected AGN Multiwavelength Properties Catalog (25 Jul 2017) The catalog of the multiwavelength properties of 692 X-ray detected AGN and their far-infrared (FIR) detected host galaxies in the redshift range from 0.1 to 4 that have been found in the COSMOS field (from Lanzuisi et al. 2017, A&A, 602, A123) is now available in Browse and Xamin. SkyView v3.3.0: Swift XRT surveys (24 Jul 2017) Versions 3.3.0 of SkyView was released today.  This includes an all-sky mosaic of the Swift XRT observations.  Over 129,000 XRT observations were combined to give coverage of just under 6% of the sky.  A set of three surveys were produced: … Continue reading → Chandra CALDB 4.7.5.1 installed at the HEASARC (21 Jul 2017) CalDB 4.7.5.1 is now installed and available at the HEASARC. Chandra 4.7.5.1 was released by the CXC on July 20, 2017... NuSTAR CALDB Update (21 Jul 2017) The NuSTAR CALibration DataBase was updated on July 21, 2017 (CALDB version 20170720). This updates the NuSTAR clock correction file to version 73, valid through 2017-07-20. Press Release: Astrosat, Chandra, Hubble Simultaneously Detect a Coronal Explosion on the Nearest Planet-Hosting Star (20 Jul 2017) Stars like Proxima Centauri are known to flare on timescales of a few minutes to hours. The ongoing analysis of the data for this flare detected on 31 May 2017 suggests that the flux increases by several orders of magnitude in both X-rays and UV and lasts ~1800 seconds. The energy released during this flare is of the order of ~10 30 erg, 100 times the energy of large solar flares. Sloan Digital Sky Survey Quasar Catalog (12th Data Release: DR12Q) (20 July 2017) The SDSS DR12Q Catalog listing the X-ray, UV, optical, IR and radio properties of 297,301 quasars, as well as their redshifts, that were identified in the Baryon Oscillation Spectroscopic Survey (BOSS) of the SDSS-III via visual inspection of their spectra (from Paris et al. 2017, A&A, 597, A79) is now available in Browse and Xamin [What is this?]
