Warm Molecular Hydrogen in the Galactic Wind of M82

S. Veilleux, D. S. N. Rupke, R. Swaters

We report the detection of a complex of extraplanar warm H_2 knots and filaments extending more than ~3 kpc above and below the galactic plane of M82, roughly coincident with the w…

First direct metallicity measurement of a lensed star-forming galaxy at z=1.7

T. -T. Yuan, L. J. Kewley

We present the rest-frame optical spectrum of a strongly lensed galaxy at redshift z =1.7 behind the cluster Abell 1689. We detect the temperature sensitive auroral line [O III] 43…

Turning Back the Clock: Inferring the History of the Eight O'clock Arc

Steven L. Finkelstein, Casey Papovich, Gregory Rudnick +5

We present the results from an optical and near-infrared spectroscopic study of the ultraviolet-luminous z = 2.73 galaxy, the 8 o'clock arc. Due to gravitational lensing, this gala…

Speckle Suppression Through Dual Imaging Polarimetry, and a Ground-Based Image of the HR 4796A Circumstellar Disk

Sasha Hinkley, Ben R. Oppenheimer, Remi Soummer +7

We demonstrate the versatility of a dual imaging polarimeter working in tandem with a Lyot coronagraph and Adaptive Optics to suppress the highly static speckle noise pattern--the…

The 0.8-14.5 micron Spectra of Mid-L to Mid-T Dwarfs: Diagnostics of Effective Temperature, Grain Sedimentation, Gas Transport, and Surface Gravity

D. C. Stephens, S. K. Leggett, Michael C. Cushing +6

We present new 5.2-14.5 micron low-resolution spectra of 14 mid-L to mid-T dwarfs, as well as 3.0-4.1 micron spectra for five of these dwarfs. These data are supplemented by existi…

Albedos of Small Jovian Trojans

Y. R. Fernandez, D. Jewitt, J. E. Ziffer

We present thermal observations of 44 Jovian Trojan asteroids with diameters (D) ranging from 5 to 24 km. All objects were observed at a wavelength of 24 microns with the Spitzer S…
