A refined model for spinning dust radiation
Y. Ali-Haïmoud, C. M. Hirata, C. Dickinson
We present a comprehensive treatment of the spectrum of electric dipole emission from spinning dust grains, updating the commonly used model of Draine and Lazarian. Grain angular v…
Young L Dwarfs Identified in the Field: A Preliminary Low-Gravity, Optical Spectral Sequence from L0 to L5
Kelle L. Cruz, J. Davy Kirkpatrick, Adam J. Burgasser
We present an analysis of 23 L dwarfs whose optical spectra display unusual features. Twenty-one were uncovered during our search for nearby, late-type objects using the Two Micron…
Photometric redshift accuracy in AKARI Deep Surveys
M. Negrello, S. Serjeant, C. Pearson +11
We investigate the photometric redshift accuracy achievable with the AKARI infrared data in deep multi-band surveys, such as in the North Ecliptic Pole field. We demonstrate that t…
Interstellar Extinction and Long-Period Variables in the Galactic Center
M. Schultheis, K. Sellgren, S. Ramirez +4
We use the Spitzer IRAC catalogue of the Galactic Center (GC) point sources (Ramirez et al. 2008) and combine it with new isochrones (Marigo et al. 2008) to derive extinctions base…
The Dust-to-Gas Ratio in the Small Magellanic Cloud Tail
K. D. Gordon, C. Bot, E. Muller +21
The Tail region of the Small Magellanic Cloud (SMC) was imaged using the MIPS instrument on the Spitzer Space Telescope as part of the SAGE-SMC Spitzer Legacy. Diffuse infrared emi…
MAMBO 1.2mm observations of luminous starbursts at z~2 in the SWIRE fields
C. J. Lonsdale, M. Polletta, A. Omont +19
We report on--off pointed MAMBO observations at 1.2 mm of 61 Spitzer-selected star-forming galaxies from the SWIRE survey. The sources are selected on the basis of bright 24um flux…
