Observation of contemporaneous optical radiation from a γ-ray burst
Carl W. Akerlof,R. Balsano,Scott Barthelmy,Scott Barthelmy,Jeffrey J. Bloch,P. Butterworth,P. Butterworth,Donald E. Casperson,T. L. Cline,S. Fletcher,Filippo Frontera,Galen Gisler,John Heise,J. Hills,Robert Kehoe,Byungjun Lee,S. L. Marshall,Timothy A. McKay,Robert Miller,L. Piro,William C. Priedhorsky,John J. Szymanski,Jim Wren +22 more
TL;DR: In this paper, the authors reported the detection of bright optical emission from GRB990123 while the burst was still in progress, and the redshift of this burst, z ≈ 1.6, implies a peak optical luminosity of 5× 1049 −1.
Journal ArticleDOI

Journal ArticleDOI
ROTSE All-Sky Surveys for Variable Stars. I. Test Fields
Carl W. Akerlof,Susan Amrose,R. Balsano,Jeffrey J. Bloch,Donald E. Casperson,S. Fletcher,Galen Gisler,J. Hills,Robert Kehoe,Brian C. Lee,S. L. Marshall,Timothy A. McKay,A. Pawl,J. Schaefer,John J. Szymanski,Jim Wren +15 more
TL;DR: In this paper, the first results of a search for periodic variable stars derived from ROTSE-I observations are presented, and the results show that about 90% of these objects are newly identified as variable.
