Abstract:
The eROSITA X-ray telescope on board the SRG observatory performed
Calibration and Performance Verification (CalPV) observations between
September 2019 and December 2019, ahead of the planned four-year
all-sky surveys. Most of them were deep, pointing-mode observations.
We present here the X-ray catalog detected from the set of
extra-galactic CalPV observations released to the public by the German
eROSITA consortium, and the multi-band counterparts of these X-ray
sources. We develop a source detection method optimized for point-like
X-ray sources by including extended X-ray emission in the background
measurement. The multi-band counterparts are identified using a
Bayesian method from the CatWISE catalog. Combining 11 CalPV fields,
we present a catalog containing 9522 X-ray sources, whose X-ray fluxes
are measured through spectral fitting. CatWISE counterparts are
presented for 77% of the sources. Significant variabilities are found
in 99 of the sources, which are also presented with this paper. Most
of these fields show similar number counts of point sources as typical
extragalactic fields, and a few harbor particular stellar populations.
Description:
This serendipitous survey combines 11 extragalactic fields, which
target various types of astronomical objects for various purposes.
The bright AGN 3C390.3 was observed for commissioning (COM) and
calibration of the ART-XC telescope; six fields were observed for
calibration (CAL) purposes targeting well-known, bright X-ray sources;
and the other four fields were performance verification (PV)
observations designed with the scientific goals of investigating
galaxy cluster (Abell 3391/3395, PI Thomas Reiprich), AGN
(1H 0707-495, PI Thomas Boller), ULX (NGC 7793 P13, PI Joern Wilms),
and Galactic dark cloud (TGU H2213 P1, PI Michael Freyberg).
We compile a catalog of 9515 sources detected in the 11 fields.
For each source, count rates are both measured during the source
detection in the three source-detection bands (0.2-0.6, 0.6-2.3,
2.3-5keV) and during post-hoc forced photometry in the two
forced-photometry bands (0.5-2, 2.3-5keV).
We identify the multiband counterparts of our X-ray sources following
the counterpart identification of the eFEDS catalog (Salvato et al.,
2022A&A...661A...3S 2022A&A...661A...3S, Cat. J/A+A/661/A3).
