Thermal and Non-Thermal Infrared Emission from M87
Y. Shi, G. H. Rieke, D. C. Hines +2
We discuss images of M87 from 3.6 to 160 um obtained with Spitzer. As found previously, there is an excess in the far infrared over a simple power law interpolation from the radio…
Hubble Space Telescope Ultraviolet Spectroscopy of Fourteen Low-Redshift Quasars
Rajib Ganguly, Michael S. Brotherton, Nahum Arav +35
We present low-resolution ultraviolet spectra of 14 low redshift (z<0.8) quasars observed with HST/STIS as part of a Snap project to understand the relationship between quasar outf…
Unravelling Temporal Variability in Saturn's Spiral Density Waves: Results and Predictions
Matthew S. Tiscareno, Philip D. Nicholson, Joseph A. Burns +2
We describe a model that accounts for the complex morphology of spiral density waves raised in Saturn's rings by the co-orbital satellites, Janus and Epimetheus. Our model may be c…
A Large Mass of H2 in the Brightest Cluster Galaxy in Zwicky 3146
E. Egami, G. H. Rieke, D. Fadda +1
We present the Spitzer/IRS mid-infrared spectrum of the infrared-luminous (L_{IR}=4e11 L_sun) brightest cluster galaxy (BCG) in the X-ray-luminous cluster Z3146 (z=0.29). The spect…
Cassini Imaging of Saturn's Rings II: A Wavelet Technique for Analysis of Density Waves and Other Radial Structure in the Rings
Matthew S. Tiscareno, Joseph A. Burns, Philip D. Nicholson +2
We describe a powerful signal processing method, the continuous wavelet transform, and use it to analyze radial structure in Cassini ISS images of Saturn's rings. Wavelet analysis…
Mid-Infrared Observations of Class I/Flat-Spectrum Systems in Six Nearby Molecular Clouds
Karl E. Haisch, Mary Barsony, Michael E. Ressler +1
We have obtained new mid-infrared observations of 65 Class I/Flat-Spectrum (F.S.) objects in the Perseus, Taurus, Chamaeleon I/II, Rho Ophiuchi, and Serpens dark clouds. We detecte…
Debris Disk Evolution Around A Stars
K. Y. L. Su, G. H. Rieke, J. A. Stansberry +8
We report 24 and/or 70 um measurements of ~160 A-type main-sequence stars using the Multiband Imaging Photometer for Spitzer (MIPS). Their ages range from 5 to 850 Myr based on est…
A Survey for New Members of Taurus with the Spitzer Space Telescope
K. L. Luhman, B. A. Whitney, M. R. Meade +4
We present the results of a search for new members of the Taurus star-forming region using the Infrared Array Camera (IRAC) aboard the Spitzer Space Telescope}. With IRAC images of…
Interpreting Spectral Energy Distributions from Young Stellar Objects. I. A grid of 200,000 YSO model SEDs
Thomas P. Robitaille, Barbara A. Whitney, Remy Indebetouw +2
We present a grid of radiation transfer models of axisymmetric young stellar objects (YSOs), covering a wide range of stellar masses (from 0.1Msun to 50Msun) and evolutionary stage…
