Optical Photometry of the GRB 010222 Afterglow
The optical afterglow of GRB 010222 was observed using the recently installed 2-m telescope at the Indian Astronomical Observatory Hanle and the telescopes at the Vainu Bappu Observatory, Kavalur, beginning ∼ 0.6 day after the detection of the event. The results based on these photometric observations combined with others reported in the literature are presented in this paper. The R band light ...
متن کاملHubble Space Telescope and Ground-Based Optical and Ultraviolet Observations of GRB010222
We report on Hubble Space Telescope WFPC2 optical and STIS near ultraviolet MAMA observations, and ground-based optical observations of GRB010222, spanning 15 hrs to 71 days. The observations are well-described by a relativistic blast-wave model with a hard electron-energy distribution, p = 1.57 −0.03, and a jet transition at t∗ = 0.93 +0.15 −0.06 days. These values are slightly larger than pre...
متن کاملOptical and radio observations of the bright GRB 010222 afterglow: evidence for rapid synchrotron cooling?
We report photometric observations of the optical afterglow of GRB 010222 in V , R and I passbands carried out between 22–27 February 2001 at Nainital. We determine the CCD Johnson BV and Cousins RI photometric magnitudes for 31 stars in the field of GRB 010222 and use them to calibrate our measurements as well as other published BV RI photometric magnitudes of the GRB 010222 afterglow. We cons...

متن کاملCOSMOS : Hubble Space Telescope Observations
The Cosmic Evolution Survey (COSMOS) was initiated with an extensive allocation (590 orbits in Cycles 12-13) using the Hubble Space Telescope (HST) for high resolution imaging. Here we review the characteristics of the HST imaging with the Advanced Camera for Surveys (ACS) and parallel observations with NICMOS and WFPC2. A square field (1.8⊓⊔) has been imaged with single-orbit ACS I-F814W expos...
