Time-dependent Optical Spectroscopy of GRB 010222: Clues to the Gamma-Ray Burst Environment*
Nestor Mirabal,Jules P. Halpern,Shrinivas R. Kulkarni,Sandra Castro,J. S. Bloom,S. G. Djorgovski,Titus Galama,Fiona A. Harrison,Dale A. Frail,P. A. Price,Daniel E. Reichart,Harald Ebeling,Andrew Bunker,Steve Dawson,Arjun Dey,Hyron Spinrad,Daniel Stern +16 more
TL;DR: In this article, the authors present sequential optical spectra of the afterglow of GRB 010222 obtained 1 day apart using the Low-Resolution Imaging Spectrometer (LRIS) and the Echellette Spectrograph and Imager (ESI) on the Keck Telescopes.

TL;DR: In this paper, the authors present results obtained from two broadband X-ray observations of the extreme ultraluminous Xray source (ULX) NGC 5907 ULX1, known to have a peak Xray luminosity of ~5 × 10^(40) erg s^(1).

Rocca-Volmerange,Andrea Cimatti,S. di Serego Alighieri,Harald Kuntschner,Barbara Lanzoni,Mario Nonino,Paola Popesso,Daniel Stern,Peter Eisenhardt,Christopher Lidman,S. A. Stanford,S. A. Stanford +20 more
TL;DR: In this article, the relationship between galaxy stellar masses and dynamical masses was explored based on multi-wavelength photometry spectral template fitting and published velocity dispersion measurements, for a sample of 48 early-type galaxies at z ∼ I with HST/ACS morphological information.

Journal ArticleDOI
H$\alpha$ Star Formation Rates of $z$ > 1 Galaxy Clusters in the IRAC Shallow Cluster Survey
Gregory R. Zeimann,S. A. Stanford,Mark Brodwin,Anthony H. Gonzalez,Conor L. Mancone,Gregory F. Snyder,Daniel Stern,Peter Eisenhardt,Arjun Dey,John Moustakas +9 more
TL;DR: In this article, the authors used Wide Field Camera 3 grism data to identify H$\alpha$ emitters in both the cores of galaxy clusters as well as in field galaxies, and they found a large cluster-to-cluster scatter in the star formation rates within a projected radius of 500 kpc.
