The properties of the Galactic Hard X-Ray and soft gamma-ray Background based on 20 years of INTEGRAL/IBIS observations
Roman Krivonos, Ekaterina Shtykovskaya, Sergey Sazonov
We present results of a study of the Galactic hard X-ray and soft gamma-ray background emission performed with the IBIS telescope aboard the INTEGRAL observatory using data obtaine…
Superflare on a rapidly-rotating solar-type star captured in X-rays
Andrey Mukhin, Roman Krivonos, Ilfan Bikmaev +5
In this work, we studied X-ray source SRGe~J021932.4040154 (SRGe J021932), which we associated with a single X-ray active star of spectral class G2V-G4V and the rotational perio…
Deep Hard X-ray Survey of the M81 Field Based on INTEGRAL Data
R. Krivonos, I. Mereminskiy, S. Sazonov
We have carried out a deep survey of the M81 field in the 25-60 keV energy band based on long-term (2003-2023) INTEGRAL observations. A record sensitivity of 0.16 mCrab at a detect…
Geminga's pulsar halo: an X-ray view
Silvia Manconi, Jooyun Woo, Ruo-Yu Shang +6
Geminga is the first pulsar around which a remarkable TeV gamma-ray halo extending over a few degrees was discovered by MILAGRO, HAWC and later by H.E.S.S., and by Fermi-LAT in the…
X-ray measurement of a high-mass white dwarf and its spin for the intermediate polar IGR J18434-0508
Julian Gerber, Jeremy Hare, John A. Tomsick +8
IGR J18434-0508 is a Galactic Intermediate Polar (IP) type Cataclysmic Variable (CV) previously classified through optical spectroscopy. The source is already known to have a hard…
eUDS: The SRG/eROSITA X-ray Survey of the UKIDSS Ultra Deep Survey Field. Catalogue of Sources
R. Krivonos, M. Gilfanov, P. Medvedev +2
The eROSITA X-ray telescope on board the Spectrum-Roentgen-Gamma (SRG) spacecraft observed the field of the UKIDSS Ultra-Deep Survey (UDS) in August-September 2019, during its flig…
