Observations of GRBs at high redshift
, 2007
"... The extreme luminosity of gamma-ray bursts and their afterglows means they are detectable, in principle, to very high redshifts. Although the redshift distribution of GRBs is difficult to determine, due to incompleteness of present samples, we argue that for Swift-detected bursts the median redshift ..."

Improving Swift-XRT positions of GRBs
"... Abstract. Since GRBs fade rapidly, it is important to publish accurate, precise positions at early times. For Swift-detected bursts, the best promptly available position is most commonly the X-ray Telescope (XRT) position. We present two processes, developed by the Swift team at Leicester, which ar ..."

Post-Launch Analysis of Swift’s Gamma-Ray Burst Detection Sensitivity
, 2006
"... The dependence of Swift’s detection sensitivity on a burst’s temporal and spectral properties shapes the detected burst population. Using simplified models of the detector hardware and the burst trigger system I find that Swift is more sensitive to long, soft bursts than CGRO’s BATSE, a reference de ..."

Early afterglow detection in the Swift observations of
, 2007
"... We present results of Swift optical, UV and X-ray observations of the afterglow of GRB 050801. The source is visible over the full optical, UV and X-ray energy range of the Swift UVOT and XRT instruments. Both optical and X-ray lightcurves exhibit a broad plateau (∆t/t ∼ 1) during the first few hund ..."

SWIFT UVOT DETECTION OF GRB 050318
"... ABSTRACT We present observations of GRB 050318 by the Ultraviolet /Optical Telescope ( UVOT ) on board the Swift observatory. The data are the first detections of a gamma-ray burst (GRB) afterglow decay by the UVOT instrument, launched specifically to open a new window on these transient sources. W ..."

Detectability of GRB Iron Lines by Swift, Chandra and XMM
, 2008
"... The rapid acquisition of positions by the upcoming Swift satellite will allow the monitoring for X-ray lines in GRB afterglows at much earlier epochs than was previously feasible. We calculate the possible significance levels of iron line detections as a function of source redshift and observing tim ..."

time after the trigger, for the Swift XRT, Chandra ACIS and XMM Epic detectors. For standard burst luminosities and decay rates and equivalent widths of 1 keV as previously reported, depending on the source-frame epoch at which the lines appear, Swift may be able to detect lines up to z ∼ 7 with a
Baltic Astronomy, vol.12, XXX–XXX, 2003. SWIFT’S ABILITY TO DETECT GAMMA-RAY BURSTS
, 2003
"... The Swift satellite will be a self-contained observatory that will bring new capabilities to the observing of the early afterglow emission of Gamma-ray Bursts. Swift is completely autonomous and will do all of the observations without help from the ground. There are three instruments on Swift. A lar ..."

gamma-ray, x-ray, and optical observations of Gamma-ray bursts soon after the burst. A key to the success of Swift will be its ability to detect and locate a large number of gamma-ray bursts quick enough that the narrow field of view instruments can follow up. The results of simulations show that Swift
