Abstract
The BATSE Earth Occultation data has been successfully used to
study the temporal and spectral properties of a mini-
sample of Seyfert 2 galaxies in the 20-100 keV energy over
a period of 9 years. The sample
used is the Maiolino and Rieke
sample restricted in distance to those objects (28) located within
40 Mpc from Earth. Of the 18 sources so far analysed
11 were detected at greater than 5 sigma level; some of these
are new detections in the X-ray band.
Preliminary results of this study will be presented including
light curves, spectra and images. To enlarge the scope of our study
we also present a comparison with our data with
data obtained by other instruments operating in the X-/gamma-ray band. The
implications of these results to the Unified Model of AGN, the Seyfert 2
luminosity function, and the LogN-logS relation is discussed.
