The Expected Detection of Dust Emission from High-Redshift Lyman Alpha Galaxies
Steven Finkelstein, Sangeeta Malhotra, James Rhoads +2
Recent results have shown that a substantial fraction of high-redshift Lyman alpha galaxies contain considerable amounts of dust. This implies that Lyman alpha galaxies are not pri…
Emission-Line Galaxies from the PEARS Hubble Ultra Deep Field: A 2-D Detection Method and First Results
Amber N. Straughn, Gerhardt R. Meurer, Norbert Pirzkal +11
The Hubble Space Telescope (HST) Advanced Camera for Surveys (ACS) grism PEARS (Probing Evolution And Reionization Spectroscopically) survey provides a large dataset of low-resolut…
Effects of Dust Geometry in Lyman Alpha Galaxies at z = 4.4
Steven L. Finkelstein, James E. Rhoads, Sangeeta Malhotra +2
Equivalent widths (EWs) observed in high-redshift Lyman alpha galaxies could be stronger than the EW intrinsic to the stellar population if dust is present residing in clumps in th…
Infrared Emission from the Nearby Cool Core Cluster Abell 2597
Megan Donahue, Andres Jordan, Stefi A. Baum +9
We observed the brightest central galaxy (BCG) in the nearby (z=0.0821) cool core galaxy cluster Abell 2597 with the IRAC and MIPS instruments on board the Spitzer Space Telescope.…
A Luminosity Function of Lyman Alpha Emitting Galaxies at Redshift 4.5
Steve Dawson, James E. Rhoads, Sangeeta Malhotra +5
We present a catalog of 59 z=4.5 Lyman alpha emitting galaxies spectroscopically confirmed in a campaign of Keck/DEIMOS follow-up observations to candidates selected in the Large A…
Chandra X-ray Sources in the LALA Cetus Field
J. X. Wang, Z. Y. Zheng, S. Malhotra +4
The 174 ks Chandra Advanced CCD Imaging Spectrometer exposure of the Large Area Lyman Alpha Survey (LALA) Cetus field is the second of the two deep Chandra images on LALA fields. I…
