Abstract:
We compiled a sample of 95 AGNs serendipitously detected in the
3-20keV band at Galactic latitude |b|>10deg during the RXTE slew
survey (XSS, Revnivtsev et al., Cat. J/A+A/418/927), and utilize it
to study the statistical properties of the local population of AGNs,
including the X-ray luminosity function and absorption distribution.
We find that among low X-ray luminosity (LX<1043.5erg/s) AGNs, the
ratio of absorbed (characterized by intrinsic absorption in the range
1022cm-2<NH<1024cm-2) and unabsorbed (NH<1022cm-2) objects
is 2:1, while this ratio drops to less than 1:5 for higher luminosity
AGNs. The summed X-ray output of AGNs with LX>1041erg/s estimated
here is smaller than the earlier estimated total X-ray volume
emissivity in the local Universe, suggesting that a comparable X-ray
flux may be produced together by lower luminosity AGNs, non-active
galaxies and clusters of galaxies. Finally, we present a sample of 35
AGN candidates, composed of unidentified XSS sources.
Description:
Catalog of 95 identified AGNs serendipitously detected at |b|>10deg
during the RXTE slew survey (XSS, J/A+A/418/927) is presented. Most
of these AGNs belong to the local population (z<0.1). For each source
the following information is provided: AGN class, count rate in two
energy bands 3-8keV and 8-20keV, observed and intrinsic
(absorption-corrected) luminosity in the 3-20keV band, intrinsic
absorption column density. Also a catalog of 35 AGN candidates,
composed of unidentified XSS sources is presented.

Note (1): AGN classification is as follows:
RQQ: radio-quiet quasar
RLQ: radio-loud quasar
BL: blazar (BL Lac object or flat-spectrum radio quasar)
S1: Seyfert 1 galaxy (types 1, 1.2 and 1.5)
NLS1: narrow-line Seyfert 1 galaxy
S2: Seyfert 2 galaxy (types 1.8, 1.9 and 2)
RG: radio galaxy
BLRG: broad-line radio galaxy
NLRG: narrow-line radio galaxy
LLAGN: low luminosity AGN
Note (2): Distance adopted for 10 nearby sources, in the other cases
luminosity distance was computed assuming
(H0,Omegam,Omegalambda)=(75km/s/Mpc, 0.3, 0.7)
Note (3): Limits are 1 sigma if based on XSS hardness ratio and more
conservative in other cases.
