CHANDRA X-ray point sources in Cen A (NGC 5128)
Listed in IVOA Registry (Virtual Observatory)
We have studied the X-ray point source population of Centaurus A (NGC 5128) using data from four archival CHANDRA observations.
Description
We detected 272 point-like X-ray sources within a radius of 10' from the centre. Approximately half of these are CXB sources, with the remaining half being LMXBs.
The spatial distribution of the LMXBs, both azimuthally averaged and 2D, is consistent with the distribution of the K-band light observed in the 2MASS survey. After correction for the incompleteness effect we constrain the LMXB luminosity function down to ~2x10^36^erg/s, much lower than previous studies of LMXBs in elliptical galaxies.
