The Interstellar Medium of GRB Host Galaxies I. Echelle Spectra of Swift GRB Afterglows
J. X. Prochaska, H. -W. Chen, J. S. Bloom +8
We present optical echelle spectra of four gamma-ray burst (GRB) afterglows (GRB 050730, GRB 050820, GRB 051111, and GRB 060418) discovered during the first 1.5 years of operation…
Reconstructed Density and Velocity Fields from the 2MASS Redshift Survey
Pirin Erdogdu, Ofer Lahav, John P. Huchra +13
We present the reconstructed real-space density and the predicted velocity fields from the Two Mass Redshift Survey (2MRS). The 2MRS is the densest all-sky redshift survey to date…
TrES-2: The First Transiting Planet in the Kepler Field
Francis T. O'Donovan, David Charbonneau, Georgi Mandushev +17
We announce the discovery of the second transiting hot Jupiter discovered by the Trans-atlantic Exoplanet Survey. The planet, which we dub TrES-2, orbits the nearby star GSC 03549-…
A Time Delay for the Largest Gravitationally Lensed Quasar: SDSS J1004+4112
J. Fohlmeister, C. S. Kochanek, E. E. Falco +12
We present 426 epochs of optical monitoring data spanning 1000 days from December 2003 to June 2006 for the gravitationally lensed quasar SDSS J1004+4112. The time delay between th…
A Putative Early-Type Host Galaxy for GRB 060502B: Implications for the Progenitors of Short-Duration Hard-Spectrum Bursts
J. S. Bloom, D. A. Perley, H. -W. Chen +6
Starting with the first detection of an afterglow from a short-duration hard-spectrum gamma-ray burst (SHB) by Swift last year, a growing body of evidence has suggested that SHBs a…
The Dipole Anisotropy of the 2mass Redshift Survey
P. Erdogdu, J. P. Huchra, O. Lahav +14
We estimate the flux weighted acceleration on the Local Group (LG) from the near-infrared Two Micron All Sky Redshift Survey (2MRS). The near-infrared flux weighted dipoles are ver…
