The fading of two transient ultraluminous x-ray sources to below the stellar mass Eddington limit
(2013-09-20)
We report new detections of the two transient ultraluminous X-ray sources (ULXs) in NGC 5128 from an ongoing series of Chandra observations. Both sources have previously been observed L (2-3) × ∼10 erg s, at the lower end ...
Spectral properties of X-ray binaries in Centaurus A
(2013-04-01)
We present a spectral investigation of X-ray binaries (XBs) in NGC 5128 (Cen A), using six 100 ks Chandra observations taken over two months in 2007. We divide our sample into thermally and non-thermally dominated states ...
A transient sub-Eddington black hole X-ray binary candidate in the dust lanes of Centaurus A
(2012-04-20)
We report the discovery of a bright X-ray transient CXOU J132527.6-430023 in the nearby early-type galaxy NGC5128. The source was first detected over the course of five Chandra observations in 2007, reaching an unabsorbed ...
