The peculiar small-scale X-ray morphology of NGC 5846 observed with Chandra.

TRINCHIERI G. and GOUDFROOIJ P.

Abstract (from CDS):

The excellent quality of the Chandra observation of NGC 5846 reveals a complex X-ray morphology of the central regions of this galaxy. An intriguing morphological similarity between the X-ray and the optical line emission, discovered before using ROSAT HRI images (Trinchieri et al., 1997A&A...326..565T, 1997A&A...318..361T), is confirmed here in unprecedented detail. Complex spectral characteristics are associated with the morphological peculiarities, indicating a possibly turbulent gas in this object. A population of ∼40 individual sources is also observed, with Lx in the range ∼3x1038-2x1039erg/s, with an X-ray luminosity function that is steeper in the high-luminosity end than in other early-type galaxies.
