The ambiguous AT2022rze: Changing-look AGN mimicking a supernova in a merging galaxy system
P. J. Pessi, R. Lunnan, J. Sollerman +36
AT2022rze is a luminous, ambiguous transient located South-East of the geometric center of its host galaxy at redshift z = 0.08. The host appears to be formed by a merging galaxy s…
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…
Hard X-rays and QPO in Swift J1727.8-1613: the rise and plateau of the 2023 outburst
I. Mereminskiy, A. Lutovinov, S. Molkov +5
We report on the detection of type-C quasi-periodic oscillations during the initial stages of the outburst of Swift J1727.8-1613 in 2023. Using data of the INTEGRAL observatory alo…
INTEGRAL IBIS, SPI, and JEM-X observations of LVT151012
V. Savchenko, A. Bazzano, E. Bozzo +18
During the first observing run of LIGO, two gravitational wave events and one lower-significance trigger (LVT151012) were reported by the LIGO/Virgo collaboration. At the time of L…
Gamma-Ray emission from SN2014J near maximum optical light
J. Isern, P. Jean, E. Bravo +17
The optical light curve of Type Ia supernovae (SNIa) is powered by thermalized gamma-rays produced by the decay of 56Ni and 56Co, the main radioactive isotopes synthesized by the t…
Gamma-rays from Type Ia supernova SN2014J
E. Churazov, R. Sunyaev, J. Isern +8
The whole set of INTEGRAL observations of type Ia supernova SN2014J, covering the period 19-162 days after the explosion has being analyzed. For spectral fitting the data are split…
