Arp102B is a nearby radio galaxy which displays the presence of double peaked
Balmer emission lines. Sub-arcsec Keck mid-infrared imaging and Spitzer
spectroscopy reveal a spatially compact mid-infrared source which displays
tentative evidence for variability. The Fν∝ν−1.2 spectral
energy distribution is suggestive of an advection dominated accretion flow. The
absence of dust features over the 5-40 micron range make it unlikely that
thermal dust emission dominates the mid-infrared luminosity. We also detect the
presence of molecular hydrogen in emission which is asymmetrically redshifted
by ~500-1000 km/s from the systemic velocity of the galaxy. Since the
forbidden, low ionization lines in this galaxy are at the systemic velocity, we
suggest that the molecular hydrogen emission arises from a rotating molecular
gas structure surrounding the nuclear black hole at a distance of ~1 pc.Comment: 4 pages, 3 figures, Conference proceedings to appear in "The Central
