Strong PAH Emission from z~2 ULIRGs
Vandana Desai, B. T. Soifer, Arjun Dey +15
Using the Infrared Spectrograph on board the Spitzer Space Telescope, we present low-resolution (64 < lambda / dlambda < 124), mid-infrared (20-38 micron) spectra of 23 high-redshi…
Research Science and Education: The NSF's Astronomy and Astrophysics Postdoctoral Fellowship
Dara Norman, Marcel Agueros, Timothy M. Brown +29
The NSF's Astronomy and Astrophysics Postdoctoral Fellowship (AAPF) is exceptional among the available postdoctoral awards in Astronomy and Astrophysics. The fellowship is one of t…
Towards the 2020 vision of the baryon content of galaxy groups and clusters
A. Kravtsov, A. Gonzalez, A. Vikhlinin +12
Groups and clusters of galaxies occupy a special position in the hierarchy of large-scale cosmic structures because they are the largest and the most massive (from ~10^13 Msun to o…
A New Era in Extragalactic Background Light Measurements: The Cosmic History of Accretion, Nucleosynthesis and Reionization
Asantha Cooray, Alexandre Amblard, Charles Beichman +52
(Brief Summary) What is the total radiative content of the Universe since the epoch of recombination? The extragalactic background light (EBL) spectrum captures the redshifted ener…
A Multiply Imaged Luminous Infrared Galaxy Behind the Bullet Cluster
Anthony H. Gonzalez, Doug Clowe, Marusa Bradac +3
We present evidence for a Spitzer-selected luminous infrared galaxy (LIRG) behind the Bullet Cluster. The galaxy, originally identified in IRAC photometry as a multiply imaged sour…
