Abstract:
We present the first source catalog of the Solid-state Slit Camera
(SSC) of the Monitor of All-sky X-ray Image (MAXI) mission on the
International Space Station, using the 45-month data from 2010 August
to 2014 April in the 0.7-7.0keV bands. Sources are searched for in two
energy bands, 0.7-1.85keV (soft) and 1.85-7.0keV (hard), the limiting
sensitivity of 3 and 4mCrab are achieved, and 140 and 138 sources are
detected in the soft and hard energy bands, respectively. Combining
the two energy bands, 170 sources are listed in the MAXI/SSC catalog.
All but 2 sources are identified with 22 galaxies including AGNs, 29
cluster of galaxies, 21 supernova remnants, 75 X-ray binaries, 8
stars, 5 isolated pulsars, and 9 non-categorized objects. Comparing
the soft-band fluxes at the brightest end in our catalog with the
ROSAT survey, which was performed about 20 years ago, 10% of the
cataloged sources are found to have changed flux since the ROSAT era.
Description:
MAXI has been in operation since 2009. However, we only use the data
taken between 2010 August 1 and 2014 April 30 for the catalog
presented in this paper.
