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…
Lyman Alpha Galaxies: Primitive, Dusty or Evolved Galaxies?
Steven L. Finkelstein, James E. Rhoads, Sangeeta Malhotra +1
We present stellar population modeling results for 10 newly discovered Lyman alpha emitting galaxies (LAEs), as well as four previously known LAEs at z ~ 4.5 in the Chandra Deep Fi…
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…
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…
The Ages and Masses of Lyman Alpha Galaxies at Redshift
Steven L. Finkelstein, James E. Rhoads, Sangeeta Malhotra +2
We examine the stellar populations of a sample of 98 redshift 4.5 Lyman alpha emitting galaxies using their broadband colors derived from deep photometry at the MMT. These galaxies…
Optical Structure and Proper-Motion Age of the Oxygen-rich Supernova Remnant 1E 0102-7219 in the Small Magellanic Cloud
Steven L. Finkelstein, Jon A. Morse, James C. Green +12
We present new optical emission-line images of the young SNR 1E 0102-7219 (E0102) in the SMC obtained with the HST Advanced Camera for Surveys (ACS). E0102 is a member of the oxyge…
