The eROSITA Final Equatorial-Depth Survey (eFEDS): Presenting The Demographics of X-ray Emission From Normal Galaxies
N. Vulic, A. E. Hornschemeier, F. Haberl +17
The Final Equatorial Depth Survey (eFEDS), completed during the calibration and performance verification phase of the instrument on $\it{Spectrum\, Ro…
Upper limits on the luminosity of the progenitor of type Ia supernova SN2014J
M. T. B. Nielsen, M. Gilfanov, A. Bogdan +2
We analysed archival data of Chandra pre-explosion observations of the position of SN2014J in M82. No X-ray source at this position was detected in the data, and we calculated uppe…
Dependence of the LMXB population on stellar age
Zhongli Zhang, Marat Gilfanov, Akos Bogdan
We investigate the dependence of the low-mass X-ray binary (LMXB) population in early-type galaxies on stellar age, by selecting 20 massive nearby early-type galaxies from the Chan…
Soft band X/K luminosity ratios in late-type galaxies and constraints on the population of supersoft X-ray sources
Akos Bogdan, Marat Gilfanov
We study X-ray to K-band luminosity ratios (L_X/L_K) of late-type galaxies in the 0.3-0.7 keV energy range. From the Chandra archive, we selected nine spiral and three irregular ga…
Unresolved X-ray emission in M31 and constraints on progenitors of Classical Novae
Akos Bogdan, Marat Gilfanov
We investigate unresolved X-ray emission from M31 based on an extensive set of archival XMM-Newton and Chandra data. We show that extended emission, found previously in the bulge a…
