  Title: ASCA OBSERVATIONS OF THE PECULIAR NLS1 GALAXY MRK507 AND THE NEARBY SEYFERT 1 GALAXY KAZ163


Abstract:
 We propose a 40ks ASCA observation for the flat-spectrum narrow-line Seyfert (NLS1)
 galaxy Mrk507. ROSAT observations shows that this object shares the soft X-ray
 properties; fast variability, the lack of X-ray absorption, and large X-ray
 luminosity (Lx=1E43 erg/s), with NLS1 class objects. However, the spectral slope
 (photon-index 1.6) is exceptionally flat among the NLS1s (mean photon-index 3.4).
 The flat spectrum is good for the hard X-ray observation, and a spectroscopy with
 ASCA provides a new insight to the peculiar nature of NLS1 objects. We also intend
 to observe the bright Seyfert 1 galaxy Kaz163 10.7 arcmin away from Mrk507 at the same time.
