On the Universal X-ray Luminosity Function of Binary X-ray Sources in Galaxies
The empirically determined universal power-law shape of X-ray luminosity function of high mass X-ray binaries in galaxies is explained by fundamental mass-luminosity and mass-radius relations for massive stars. The unique possibilities offerred by modern X-ray space observatories Chandra and XMM-Newton make it possible to observe point-like X-ray sources in nearby galaxies which allows studies ...
متن کاملProbing the Low-luminosity X-ray Luminosity Function in Normal Elliptical Galaxies
We present the first low-luminosity [LX > (5 10) ; 10 ergs s ] X-ray luminosity functions (XLFs) of low-mass X-ray binaries (LMXBs) determined for two typical old elliptical galaxies, NGC 3379 and NGC 4278. Because both galaxies contain little diffuse emission from hot ISM and no recent significant star formation (hence no high-mass X-ray binary contamination), they provide two of the best homo...
متن کاملX-ray Luminosity Function of Low-mass X-ray Binaries in Galaxies
X-ray luminosity function derived from observations of X-ray sources in galactic bulges can be explained by prinicipal evolutionary relations for mass accretion rate onto the compact object. The observed mean distribution of individual X-ray luminosities of galactic LMXB is satisfactorily described by a symmetric quasi-Lorentzian curve. The flux variance for bright sources is found to be propor...
متن کاملX-ray Luminosity Function and Total Luminosity of Low-mass X-ray Binaries in Early-type Galaxies
We have derived bias-corrected X-ray luminosity functions (XLFs) of sources detected in a uniformly selected sample of 14 E and S0 galaxies observed with Chandra ACIS-S3. The entire sample yields 985 pointlike X-ray sources, with typical detections of 30–140 sources per galaxy. After correcting for incompleteness, the individual XLFs are statistically consistent with a single power law of a (di...
متن کاملX-ray Luminosity Functions of Normal Galaxies in the Goods
We present soft (0.5-2 keV) X-ray luminosity functions (XLFs) in the Great Observatories Origins Deep Survey (GOODS) fields, derived for galaxies at z ∼ 0.25 and 0.75. SED fitting was used to estimate photometric redshifts and separate galaxy types, resulting in a sample of 40 early-type galaxies and 46 late-type galaxies. We estimate k-corrections for both the X-ray/optical and Xray/NIR flux r...
