Prompt Optical Detection of GRB 050401 with ROTSE-IIIa (2005)
Rykoff, E.S., Aharonian, F., Akerlof, C. W., Alatalo, K., Ashley, M. C. B., Güver, T., ...
The ROTSE-IIIa telescope at Siding Spring Observatory, Australia, detected prompt optical emission from Swift GRB 050401. We present observations of the early optical afterglow, first detected by the...
Observing GRBs with EXIST (2004)
Hartmann, D. H., Grindlay, J., Hong, J., Loeb, A., Blandford, R., Craig, W., ...
We describe the Energetic X-ray Imaging Survey Telescope EXIST, designed to carry out a sensitive all-sky survey in the 10 keV – 600 keV band. The primary goal of EXIST is to find black holes in...
