Constraints on the parameters of keV-scale mass annihilating Dark Matter obtained with SRG/ART-XC observations
E. I. Zakharov, V. V. Barinov, R. A. Burenin +2
In this paper we present new constraints on the velocity-independent cross section of keV-scale mass annihilating Dark Matter particles obtained with SRG/ART-XC after 4 full-sky su…
The ART-XC telescope on board the SRG observatory
M. Pavlinsky, A. Tkachenko, V. Levin +59
ART-XC (Astronomical Roentgen Telescope - X-ray Concentrator) is the hard X-ray instrument with grazing incidence imaging optics on board the Spektr-Roentgen-Gamma (SRG) observator…
Optical Identification of Four Hard X-ray Sources from the INTEGRAL Sky Surveys
D. I. Karasev, S. Yu. Sazonov, A. Yu. Tkachenko +8
We continue the study begun in Karasev et al. (2018) and present the results of our optical identifications of four hard X-ray sources from the INTEGRAL sky surveys. Having first i…
The outburst of the X-ray nova GRS 1739-278 in September, 2016
I. A. Mereminskiy, E. V. Filippova, R. A. Krivonos +3
During the scanning observations of the Galactic Center region in August - September 2016 we detected the new outburst of the historical X-ray nova GRS 1739-278, the black hole can…
Hard X-ray emission of Sco X-1
Mikhail G. Revnivtsev, Sergey S. Tsygankov, Eugene M. Churazov +1
We study hard X-ray emission of the brightest accreting neutron star Sco X-1 with INTEGRAL observatory. Up to now INTEGRAL have collected ~4 Msec of deadtime corrected exposure on…
NuSTAR and Chandra Insight into the Nature of the 3-40 keV Nuclear Emission in NGC 253
B. D. Lehmer, D. R. Wik, A. E. Hornschemeier +16
We present results from three nearly simultaneous NuSTAR and Chandra monitoring observations between 2012 Sep 2 and 2012 Nov 16 of local star-forming galaxy NGC 253. The 3-40 keV N…
Population of persistent high mass X-ray binaries in the Milky Way
A. A. Lutovinov, M. G. Revnivtsev, S. S. Tsygankov +1
We present results of the study of persistent high mass X-ray binaries (HMXBs) in the Milky Way, obtained from the deep INTEGRAL Galactic plane survey. This survey provides us a ne…
Contribution of the accretion disk, hot corona, and obscuring torus to the luminosity of Seyfert galaxies: INTEGRAL and Spitzer observations
S. Sazonov, S. P. Willner, A. D. Goulding +12
We estimate the relative contributions of the supermassive black hole (SMBH) accretion disk, corona, and obscuring torus to the bolometric luminosity of Seyfert galaxies, using Spi…
Broadband Observations of the Be/X-ray Binary Pulsar RX J0440.9+4431: Discovery of a Cyclotron Absorption Line
S. Tsygankov, R. Krivonos, A. Lutovinov
We report the results of an analysis of data obtained with the INTEGRAL, Swift and RXTE observatories during the 2010 April and September outbursts of the X-ray pulsar RX J0440.9+4…
INTEGRAL/IBIS 7-year All-Sky Hard X-Ray Survey. Part II: Catalog of Sources
R. Krivonos, S. Tsygankov, M. Revnivtsev +3
This paper is the second in a series devoted to the hard X-ray (17-60 keV) whole sky survey performed by the INTEGRAL observatory over seven years. Here we present a catalog of det…
