Multicolor Infrared Observations of SN 2006aj, the Supernova Associated with XRF 060218 - Paper I
Daniel Kocevski, Maryam Modjaz, Joshua S. Bloom +8
We report simultaneous multicolor near-infrared (NIR) observations of the supernova associated with x-ray Flash 060218 during the first 16 days after the high energy event. We find…
Mid-IR Observations and a Revised Time Delay for the Gravitational Lens System Quasar HE 1104-1805
S. Poindexter, N. Morgan, C. S. Kochanek +1
The mid-IR flux ratios F_A/F_B = 2.84 +/- 0.06 of the two images of the gravitationally lensed quasar HE 1104-1805 show no wavelength dependence to within 3% across 3.6-8.0 um, no…
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…
