X-ray sources in NGC 4261
Listed in IVOA Registry (Virtual Observatory)
Chandra images of the elliptical galaxy NGC 4261 have revealed an anisotropy in the spatial distribution of the off-nuclear X-ray sources, interpreted by Zezas et al. (2003ApJ...599L..73Z) as evidence of an association with a young stellar population.
Description
Our independent analysis of archive X-ray (Chandra) and optical (INT and HST) observations confirms the anisotropy of the X-ray sources but conducts to a different interpretation for their origin.
