High Metallicity LGRB Hosts
J. F. Graham, A. S. Fruchter, E. M. Levesque +9
We present our imaging and spectroscopic observations of the host galaxies of two dark long bursts with anomalously high metallicities, LGRB 051022 and LGRB 020819B, which in conju…
ALMA Observations of the Host Galaxy of GRB090423 at z=8.23: Deep Limits on Obscured Star Formation 630 Million Years After the Big Bang
E. Berger, B. A. Zauderer, R. -R. Chary +7
We present rest-frame far-infrared (FIR) and optical observations of the host galaxy of GRB090423 at z=8.23 from the Atacama Large Millimeter Array (ALMA) and the Spitzer Space Tel…
Using Colors to Improve Photometric Metallicity Estimates for Galaxies
Nathan E. Sanders, Emily M. Levesque, Alicia M. Soderberg
There is a well known correlation between the mass and metallicity of star-forming galaxies. Because mass is correlated with luminosity, this relation is often exploited, when spec…
Variable Ly alpha sheds light on the environment surrounding GRB 090426
C. C. Thöne, S. Campana, D. Lazzati +16
Long duration gamma-ray bursts are commonly associated with the deaths of massive stars. Spectroscopic studies using the afterglow as a light source provide a unique opportunity to…
GRB 090426: The Environment of a Rest-Frame 0.35-second Gamma-Ray Burst at Redshift z=2.609
Emily M. Levesque, Joshua S. Bloom, Nathaniel R. Butler +14
We present the discovery of an absorption-line redshift of z = 2.609 for GRB 090426, establishing the first firm lower limit to a redshift for a gamma-ray burst with an observed du…
