We present the X-ray luminosity functions (XLFs) of low-mass X-ray binaries (LMXBs) determined for old elliptical galaxies, NGC 3379 and NGC 4278. Because both galaxies contain little diffuse emission from the hot ISM and no recent significant star formation (hence no high-mass X-ray binary contamination), they provide two of the best homogeneous samples of LMXBs.

Abstract
We present the X-ray luminosity functions (XLFs) of low-mass X-ray binaries (LMXBs) determined for old elliptical galaxies, NGC 3379 and NGC 4278. Because both galaxies contain little diffuse emission from the hot ISM and no recent significant star formation (hence no high-mass X-ray binary contamination), they provide two of the best homogeneous samples of LMXBs.File in questo prodotto:
