The X-ray and Radio Loud Fast Blue Optical Transient AT2020mrf: Implications for an Emerging Class of Engine-Driven Massive Star Explosions

Yuhan Yao, Anna Y. Q. Ho, Pavel Medvedev +9

We present AT2020mrf (SRGe J154754.2443907), an extra-galactic () fast blue optical transient (FBOT) with a rise time of days and a peak luminosit…

Candidate Tidal Disruption Event AT2019fdr Coincident with a High-Energy Neutrino

Simeon Reusch, Robert Stein, Marek Kowalski +46

The origins of the high-energy cosmic neutrino flux remain largely unknown. Recently, one high-energy neutrino was associated with a tidal disruption event (TDE). Here we present A…

Spatially resolved X-ray spectra of the Galactic SNR G18.95-1.1: SRG/eROSITA view

A. M. Bykov, Y. A. Uvarov, E. M. Churazov +2

Aims. We study the X-ray emission of the galactic supernova remnant (SNR) G18.95-1.1 with the eROSITA telescope on board the Spectrum Rentgen Gamma (SRG) orbital observatory. In ad…

First tidal disruption events discovered by SRG/eROSITA: X-ray/optical properties and X-ray luminosity function at z<0.6

S. Sazonov, M. Gilfanov, P. Medvedev +22

We present the first sample of tidal disruption events (TDEs) discovered during the SRG all-sky survey. These 13 events were selected among X-ray transients detected in the 0<l<180…

Observation of a very massive galaxy cluster at z=0.76 in SRG/eROSITA all-sky survey

R. A. Burenin, I. F. Bikmaev, M. R. Gilfanov +16

The results of multiwavelength observations of the very massive galaxy cluster SRGe CL2305.2-2248 detected in X-rays during the first SRG/eROSITA all-sky survey are discussed. This…

Peculiar X-ray transient SRGA J043520.9+552226/AT2019wey discovered with SRG/ART-XC

I. A. Mereminskiy, A. V. Dodin, A. A. Lutovinov +24

Context: During the ongoing all-sky survey, the Mikhail Pavlinsky ART-XC telescope on board the SRG observatory should discover new X-ray sources, many of which can be transient. H…
