Tempestuous life beyond R_500: X-ray view on the Coma cluster with SRG/eROSITA. I. X-ray morphology, recent merger, and radio halo connection
E. Churazov, I. Khabibullin, N. Lyskova +2
This is the first paper in a series of studies of the Coma cluster using the SRG/eROSITA X-ray data obtained in course of the Calibration and Performance Verification observations.…
XMM-Newton observations of the extremely X-ray luminous quasar CFHQS J142952+544717=SRGE J142952.1+544716 at redshift z=6.18
P. Medvedev, M. Gilfanov, S. Sazonov +2
We present results from a 20 ks XMM-Newton DDT observation of the radio-load quasar CFHQS J142952+544717 at z=6.18, whose extreme X-ray luminosity was recently revealed by the SRG/…
Observing imprints of black hole event horizon on X-ray spectra
Srimanta Banerjee, Marat Gilfanov, Sudip Bhattacharyya +1
A fundamental difference between a neutron star (NS) and a black hole (BH) is the absence of a physical surface in the latter. For this reason, any remaining kinetic energy of the…
INTEGRAL discovery of a burst with associated radio emission from the magnetar SGR 1935+2154
S. Mereghetti, V. Savchenko, C. Ferrigno +23
We report on INTEGRAL observations of the soft -ray repeater SGR 1935+2154 performed between 2020 April 28 and May 3. Several short bursts with fluence of …
The intermediate nebular phase of SN 2014J: onset of clumping as the source of recombination
P. A. Mazzali, I. Bikmaev, R. Sunyaev +6
At the age of about 1 year, the spectra of most Type Ia supernovae are dominated by strong forbidden nebular emission lines of FeII and FeIII. Later observations (at about 2 years)…
Impact of intrinsic polarisation of Sgr A* historical flares on (polarisation) properties of their X-ray echoes
Ildar Khabibullin, Eugene Churazov, Rashid Sunyaev
Reflection of X-ray emission on molecular clouds in the inner 100 pc of our Galaxy reveals that, despite being extremely quiet at the moment, our supermassive black hole Sgr…
