Detectability of Long GRB Afterglows from Very High Redshifts
Gamma-ray bursts are promising tools for tracing the formation of high redshift stars, including the first generation. At very high redshifts the reverse shock emission lasts longer in the observer frame, and its importance for detection and analysis purposes relative to the forward shock increases. We consider two different models for the GRB environment, based on current ideas about the redsh...
متن کاملOptical / Multiwavelength Observations of GRB Afterglows Titus
I review T-ray burst optical/multiwavelength afterglow observations since 1997, when the first counterparts to GRBs were discovered. I discuss what we have learned from multiwavelength observations of GRB afterglows in relation to the ‘standard’ fireball plus relativistic blast-wave models. To first order, the ‘standard’ model describes the afterglow observations well, but a wealth of informati...

متن کاملTwo more years of GRB optical afterglows
I review the main observational achievements concerning GRB optical afterglows occurred in the past two years Their emission seems to be well interpreted in terms of the ‘fireball’ model, although a variety of behaviours are observed. Evidence for supernova-like late time ‘bumps’ in the optical light curves is growing; however, other interpretations are possible. Fast follow-up observations all...
متن کاملEstimation of the detectability of optical orphan afterglows
Considering two main assumptions: no sideways expansion and the distribution of half-opening angle of jetted ejecta of gamma-ray bursts, we estimate the detectability of optical orphan afterglows. We show that the former assumption leads to more orphans to be detected while the latter greatly depresses the detectability compared with one single opening angle θj = 0.1 model. We also consider the...
