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…

A deep Chandra look at the low L_B elliptical NGC821: X-ray binaries, a galactic wind and emission at the nucleus
S. Pellegrini, A. Baldi, D. W. Kim +4
The relatively nearby (distance=24.1 Mpc) elliptical galaxy NGC821, hosting a central massive black hole but inactive at all wavelengths, was observed with Chandra for a total expo…
