The bright black hole X-ray binary 4U 1543--47 during 2021 outburst: a thick accretion disk inflated by high luminosity
S. J. Zhao, L. Tao, P. P. Li +17
The black hole X-ray binary source 4U 1543--47 experienced a super-Eddington outburst in 2021, reaching a peak flux of up to …
Revealing the nature of the ULX and X-ray population of the spiral galaxy NGC 4088
M. Mezcua, G. Fabbiano, J. C. Gladstone +2
We present the first \textit{Chandra} and \textit{Swift} X-ray study of the spiral galaxy NGC\,4088 and its ultraluminous X-ray source (ULX N4088--X1). We also report very long bas…
The ultraluminous X-ray source NGC 1313 X-2 - Its optical counterpart and environment
F. Grisé, M. W. Pakull, R. Soria +4
NGC 1313 X-2 is one of the brightest ultraluminous X-ray sources in the sky, at both X-ray and optical wavelengths; therefore, quite a few studies of available ESO VLT and HST data…
New flaring of an ultraluminous X-ray source in NGC 1365
R. Soria, A. Baldi, G. Risaliti +4
We have studied a highly variable ultraluminous X-ray source (ULX) in the Fornax galaxy NGC 1365, with a series of 12 Chandra and XMM-Newton observations between 2002 and 2006. In…
Black hole mass estimates from soft X-ray spectra
R. Soria, Z. Kuncic
In the absence of direct kinematic measurements, the mass of an accreting black hole is sometimes inferred from the X-ray spectral parameters of its accretion disk; specifically, f…
A deep Chandra, VLA and Spitzer IRAC study of the very low luminosity nucleus of the elliptical NGC821
S. Pellegrini, A. Siemiginowska, G. Fabbiano +5
The relatively nearby (distance=24.1 Mpc) elliptical galaxy NGC821 hosts an extreme example of a quiescent central massive black hole, for which deep Chandra observations revealed…
