Redshifts and Luminosities for 112 Gamma Ray Bursts
Bradley E. Schaefer, Ming Deng, David L. Band
Two different luminosity indicators have recently been proposed for Gamma Ray Bursts that use gamma-ray observations alone. They relate the burst luminosity (L) with the time lag b…
Discovery of the Bright Trans-Neptunian Object 2000 EB173
Ignacio Ferrin, D. Rabinowitz, B. Schaefer +45
We describe the discovery circumstances and photometric properties of 2000 EB173, now one of the brightest trans-Neptunian objects (TNOs) with opposition magnitude m_R=18.9 and als…
Discovery of the Optical Transient of the Gamma Ray Burst 990308
Bradley E. Schaefer, J. A. Snyder, J. Hernandez +53
The optical transient of the faint Gamma Ray Burst 990308 was detected by the QUEST camera on the Venezuelan 1-m Schmidt telescope starting 3.28 hours after the burst. Our photomet…
Time Dilation in the Peak-to-Peak Time Scale of GRBs
Ming Deng, Bradley E. Schaefer
We present strong evidence of time stretching in the peak-to-peak time scales in the light curves of BATSE Gamma Ray Bursts (GRBs). Extensive tests are performed on artificially di…
