Direct detection of the non-thermal X-ray emission from the Arches star cluster

Roman Krivonos, Alexey Vikhlinin, Andrei Bykov +2

The compact stellar clusters have emerged as particularly promising candidates for cosmic rays (CR) accelerators. The star clusters, recently observed in gamma-rays, are also known…

A wide-field X-ray search for the Geminga pulsar halo with SRG/ART-XC

Roman Krivonos, Silvia Manconi, Vadim Arefiev +8

Searches for the putative large-scale X-ray halo around the Geminga pulsar have been extensively performed using various narrow field-of-view X-ray telescopes. In this paper, we pr…

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…
