X-ray Constraints on the AGN Properties in Spitzer-IRS identified z~2 Ultraluminous Infrared Galaxies
F. E. Bauer, Lin Yan, A. Sajina +1
We report X-ray constraints for 20 of 52 high-z ULIRGs identified in the Spitzer xFLS to constrain their obscuration. Notably, decomposition of Spitzer-IRS spectra for the 52 objec…
Free Unstable Modes and Massive Bodies in Saturn's Outer B Ring
Joseph N. Spitale, Carolyn C. Porco
Voyager images and Cassini occultation data have previously shown that the behavior of the outer edge of Saturn's massive B ring is determined only in part by a static response to…
The Taurus Spitzer Survey: New Candidate Taurus Members Selected Using Sensitive Mid-Infrared Photometry

We report on the properties of pre-main-sequence objects in the Taurus molecular clouds as observed in 7 mid- and far-infrared bands with the Spitzer Space Telescope. There are 215…
An analytic parameterization of self-gravity wakes in Saturn's rings, with application to occultations and propellers
Matthew S. Tiscareno, Randall P. Perrine, Derek C. Richardson +4
We have developed a semi-analytic method of parameterizing N-body simulations of self-gravity wakes in Saturn's rings, describing their properties by means of only 6 numbers: 3 opt…
The Case of AB Aurigae's Disk in Polarized Light: Is There Truly a Gap?
Marshall D. Perrin, Glenn Schneider, Gaspard Duchene +4
Using the NICMOS coronagraph, we have obtained high-contrast 2.0 micron imaging polarimetry and 1.1 micron imaging of the circumstellar disk around AB Aurigae on angular scales of…

We present Hubble Space Telescope optical coronagraphic polarization imaging observations of the dusty debris disk HD 61005. The scattered light intensity image and polarization st…
Multiwavelength monitoring of the enigmatic Narrow-Line Seyfert 1 PMN J0948+0022 in March-July 2009
LAT Collaboration, E. Angelakis, C. Bailyn +39
Following the recent discovery of gamma rays from the radio-loud narrow-line Seyfert 1 galaxy PMN J0948+0022 (z=0.5846), we started a multiwavelength campaign from radio to gamma r…
Lifting the Dusty Veil II: A Large-Scale Study of the Galactic Infrared Extinction Law
G. Zasowski, S. R. Majewski, R. Indebetouw +8
We combine near-infrared (2MASS) and mid-infrared (Spitzer-IRAC) photometry to characterize the IR extinction law (1.2-8 microns) over nearly 150 degrees of contiguous Milky Way mi…
The Herschel ATLAS
S. Eales, L. Dunne, D. Clements +94
The Herschel ATLAS is the largest open-time key project that will be carried out on the Herschel Space Observatory. It will survey 510 square degrees of the extragalactic sky, four…
Warm and Dense Molecular Gas in the N159 Region: 12CO J=4-3 and 13CO J=3-2 Observations with NANTEN2 and ASTE
Yoji Mizuno, Akiko Kawamura, Toshikazu Onishi +29
New 12CO J=4-3 and 13CO J=3-2 observations of the N159 region in the Large Magellanic Cloud have been made. The 12CO J=4-3 distribution is separated into three clumps. These new me…
Star Clusters in Pseudo-Bulges of Spiral Galaxies
Daiana Di Nino, Michele Trenti, Massimo Stiavelli +3
We present a study of the properties of the star-cluster systems around pseudo-bulges of late-type spiral galaxies using a sample of 11 galaxies with distances from 17 to 37 Mpc. S…
Changes in the red giant and dusty environment of the recurrent nova RS Ophiuchi following the 2006 eruption
M. T. Rushton, B. Kaminsky, D. K. Lynch +8
We present near infrared spectroscopy of the recurrent nova RS Oph obtained on several occasions after its latest outburst in 2006 February. The 1-5 mircon spectra are dominated by…
Mid-Infrared Variability of protostars in IC 1396A
M. Morales-Calderon, J. R. Stauffer, L. Rebull +7
We have used Spitzer/IRAC to conduct a photometric monitoring program of the IC1396A dark globule in order to study the mid-IR (3.6 - 8 micron) variability of the heavily embedded…
Massive star formation and feedback in W49A: The source of our Galaxy's most luminous water maser outflow
Nathan Smith, Barbara A. Whitney, Peter S. Conti +2
We present high spatial resolution mid-IR images of the ring of UCHII regions in W49A obtained at Gemini North, allowing us to identify the driving source of its powerful H2O maser…
A Mid-Infrared Counterpart to the Magnetar 1E 2259+586
David L. Kaplan, Deepto Chakrabarty, Zhongxiang Wang +1
We report the discovery of a 4.5 um counterpart to the anomalous X-ray pulsar (magnetar) 1E 2259+586 with the Spitzer Space Telescope. The mid-infrared flux density is 6.3+/-1.0 uJ…
Hubble Space Telescope NICMOS Polarization Observations of Three Edge-on Massive YSOs
Janet P. Simpson, Michael G. Burton, Sean W. J. Colgan +4
Massive young stellar objects (YSOs), like low-mass YSOs, appear to be surrounded by optically thick envelopes and/or disks and have regions, often bipolar, that are seen in polari…
