   PR # 42137
   We propose the first ASCA observations of GHz Peaked Spectrum (GPS)
   radio galaxies: powerful, but compact ( < kpc), sources which may be
   young radio galaxies which are struggling to break free of their
   dense and dusty circumnuclear medium. ROSAT observations of our two
   targets place upper limits of 3.0E42 ergs/s on their soft x-ray
   luminosity. Our proposed ASCA observations will allow us to determine
   whether the AGNs in the GPS sources are intrinsically weak in x-rays
   or are powerful but obscured. If we detect the AGN, this will favor
   the hypothesis that they are powerful nascent classical doubles and
   we will determine the absorbing column, thus probing the properties
   of the circumnuclear medium. We will have finally identified the
   progenitors of classical double radio sources.
