X-rays breaking out of pre-explosion ejecta mark a supernova's first light
Weimin Yuan, Qiu-Ju Huang, Jin-Ping Zhu +130
Massive stars die as core-collapse supernovae, whose optical light emerges days after the implosion. Theory predicts that the initial collapse-driven shock, upon breaking through t…
New galaxy cluster in the Zone of Avoidance SRGe CL0512.7+3712. Discovery and multi-wavelength characterization
Ildar Khabibullin, Eugene Churazov, Natalya Lyskova +9
The census of massive clusters of galaxies in the local Universe is almost complete, thanks to their prominent observational signatures at X-ray, optical, and sub-mm wavelengths. N…
ComPACT: Mass-Redshift Properties of the galaxy cluster catalogue
S. Voskresenskaia, N. Lyskova, I. Zaznobin +1
Machine-learning methods are increasingly applied to astronomical surveys, providing powerful tools for detecting and studying galaxy clusters. We investigate the mass-redshift pro…
New Active Galactic Nuclei Detected by the ART-XC and eROSITA Telescopes during the First Five SRG All-Sky X-ray Surveys. Part 2
Grigory Uskov, Sergey Sazonov, Igor Zaznobin +8
We present the results of our identification of 11 X-ray sources detected on the half of the sky in the 4-12 keV energy band on the combined map of the first…
Merger of massive galaxy cluster CL0238.3+2005 at z~0.4: just after pericenter passage?
N. Lyskova, E. Churazov, I. Khabibullin +13
Massive clusters of galaxies are very rare in the observable Universe. Even rarer are mergers of such clusters observed close to pericenter passage. Here, we report on one such cas…
SRG/ART-XC all-sky X-ray survey: Catalog of sources detected during the first five surveys
S. Sazonov, R. Burenin, E. Filippova +27
We present an updated catalog of sources detected by the Mikhail Pavlinsky ART-XC telescope aboard the Spektrum-Roentgen-Gamma (SRG) observatory during its all-sky survey. It is ba…
Optical Identification and Spectroscopic Redshift Measurements of 216 Galaxy Clusters from the SRG/eROSITA All-Sky Survey
I. A. Zaznobin, R. A. Burenin, A. A. Belinski +34
We present the results of the optical identification and spectroscopic redshift measurements of 216 galaxy clusters detected in the SRG/eROSITA all-sky X-ray survey. The spectrosco…
Optical Identification of Galaxy Clusters among SRG/eROSITA X-ray Sources Based on Photometric Redshift Estimates for Galaxies
I. A. Zaznobin, R. A. Burenin, A. V. Meshcheryakov +5
We discuss an algorithm whereby the massive galaxy clusters detected in the SRG/eROSITA all-sky survey are identified and their photometric redshifts are estimated. For this purpos…
