Abstract:
The X-ray luminosity functions of galaxies have become a useful tool
for population studies of X-ray binaries in them. The availability of
long term light-curves of X-ray binaries with the All Sky X-ray
Monitors opens up the possibility of constructing X-ray luminosity
functions, by also including the intensity variation effects of the
galactic X-ray binaries. We have constructed multiple realizations of
the X-ray luminosity functions (XLFs) of Milky Way, using the long
term light-curves of sources obtained in the 2-10keV energy band
with the RXTE-ASM. The observed spread seen in the value of slope of
both HMXB and LMXB XLFs are due to inclusion of variable luminosities
of X-ray binaries in construction of these XLFs as well as finite
sample effects. XLFs constructed for galactic HMXBs in the luminosity
range 1036-1039erg/s is described by a power-law model with a
mean power-law index of -0.48 and a spread due to variability of
HMXBs as 0.19. XLFs constructed for galactic LMXBs in the luminosity
range 1036-1039erg/s has a shape of cut-off power-law with mean
power-law index of -0.31 and a spread due to variability of LMXBs
as 0.07.
Description:
We present a sample of 84 High Mass X ray Binaries and 116 Low Mass X
ray Binaries with distances found in literature with reasonable
accuracy.
