Mid Infrared Spectra of Radio Galaxies and Quasars
P. M. Ogle, R. R. J. Antonucci, D. Whysong
Spitzer Infrared Spectrograph (IRS) observations of 3C radio galaxies and quasars shed new light on the nature of the central engines of AGN. Emission from silicate dust obscuring…
Spitzer measurements of atomic and molecular abundances in the Type IIP SN 2005af
Rubina Kotak, Peter Meikle, Monica Pozzo +12
We present results based on Spitzer Space Telescope mid-infrared (3.6-30 micron) observations of the nearby IIP supernova 2005af. We report the first ever detection of the SiO mole…
Substructure in Tidal Streams; Tributaries in the Anticenter Ring
C. J. Grillmair
We report on the detection in Sloan Digital Sky Survey data of at least three, roughly parallel components in a 65 degree-long stellar stream complex previously identified with the…
Discovery of an 86 AU Radius Debris Ring Around HD 181327
Glenn Schneider, Murray D. Silverstone, Dean C. Hines +11
HST/NICMOS PSF-subtracted coronagraphic observations of HD 181327 have revealed the presence of a ring-like disk of circumstellar debris seen in 1.1 micron light scattered by the d…
Detection of a 63 Degree Cold Stellar Stream in the Sloan Digital Sky Survey
Carl J. Grillmair, Odysseas Dionatos
We report on the detection in Sloan Digital Sky Survey data of a 63 degree-long tidal stream of stars, extending from Ursa Major to Cancer. The stream has no obvious association wi…
Detection of a 60 Degree-Long Dwarf Galaxy Debris Stream
C. J. Grillmair
We report on a 60 degree-long stream of stars, extending from Ursa Major to Sextans, in the Sloan Digital Sky Survey. The stream is approximately 2 degrees wide and is clearly dist…
