“…It should be noted that for the short / hard GRBs, no optical counterpart has yet been detected in spite of extensive efforts (e.g., Kehoe et al 2001;Hurley et al 2002;Castro-Tirado et al 2002;Gorosabel et al 2002;Klotz et al 2003). However, upper limits have been given and should be useful for constraining our model by comparing them with the model light curves.…”

“…However, this remarkable progress is restricted to the long-duration class of GRBs. No counterparts at longer wavelengths have yet been found for the short-duration class bursts, in spite of intense efforts to detect the optical, infrared, and radio counterparts of several short bursts (e.g., Kehoe et al 2001;Hurley et al 2002;Castro-Tirado et al 2002;Gorosabel et al 2002;Klotz et al 2003).…”

Optical Afterglows from Cylindrical Jets of Short Gamma‐Ray Bursts

Observations of extragalactic radio jets and young stellar jets show that the jets are cylindrical; i.e., they maintain a nearly constant cross section on large scales. It has been suggested that the afterglow behaviors of some long-duration gamma-ray bursts (GRBs) are consistent with the cylindrical jet model of GRBs. Here we study the afterglow emission of cylindrical jets from short-duration GRBs. For the usual conical jet geometry, it is argued that, because of the low fluence of short GRBs, the prospects of detecting the optical afterglow 10 hr after the burst are not promising. However, in the present work we find that if the jets are cylindrical, the chance for detecting the optical afterglow will be increased, even if the burst occurs in a low-density (n $ 10 À3 cm À3 ) medium. Since the jets are expected to not be well collimated initially and the time when they change from conical to cylindrical is not exactly known, we discuss two cases for the afterglow of cylindrical jets: the jets becoming cylindrical (1) after the gamma-ray-emitting phase and (2) before the gamma-ray-emitting phase. In both cases, the light-curve behaviors, especially the peak time, are sensitive to the cross section radius of the cylindrical jet. In the former case we find that for viewing angles less than $0.03 rad relative to the jet axis, typical short GRBs have a late-time R-band afterglow with a maximum apparent magnitude of m R P 23, given that the efficiency for producing gamma rays and the shock microphysical parameters of the afterglow are the same in short and long bursts. For the latter case the optical afterglows can always be readily detected with m R < 23 at 10 hr after the burst. Comparison between model light curves and observational upper limits of the optical afterglow flux of a few short GRBs are also made.

“…The wide-field cameras were considered a primary instrument, while the ability to follow-up with a large telescope was an option. Between 1998 and 2002 the wide-field system provided simultaneous limits for several CGRO/BATSE and BeppoSAX GRBs, most notably the candidate afterglow for the short GRB 000313 [4]. The 30 cm telescope was successfully used to follow-up GRB 030329.…”

Four years of BOOTES-1B GRB follow-up history are summarised for the first time in the form of a table. The successfully followed events are described case by case.Further, the data are used to show the GRB trigger rate in Spain on a peryear basis, resulting in an estimate of 18 triggers and about 51 h of telescope time per year for real time triggers. These numbers grow to about 22 triggers and 77 h per year if we include also the GRBs observable within 2 hours after the trigger.

“…Of all the GRB afterglows so far observed, only one single epoch observation [10] of a possible optical counterpart to a short GRB was reported. It has been predicted that the afterglows of short GRBs may be much fainter than the afterglows of long GRBs [11].…”

The Liverpool Telescope: rapid follow-up observation of targets of opportunity with a 2 m robotic telescope

The Liverpool Telescope, situated at Roque de los Muchachos Observatory, La Palma, Canaries, is the first 2-m, fully instrumented robotic telescope. It recently began observations. Among Liverpool Telescope's primary scientific goals is to monitor variable objects on all timescales from seconds to years. An additional benefit of its robotic operation is rapid reaction to unpredictable phenomena and their systematic follow up, simultaneous or coordinated with other facilities. The Target of Opportunity Programme of the Liverpool Telescope includes the prompt search for and observation of GRB and XRF counterparts. A special over-ride mode implemented for GRB/XRF follow-up enables observations commencing less than a minute after the alert, including optical and near infrared imaging and spectroscopy. In particular, the moderate aperture and rapid automated response make the Liverpool Telescope excellently suited to help solving the mystery of optically dark GRBs and for the investigation of currently unstudied short bursts and XRFs.
