GRB 140515A at z=6.33: Constraints on the End of Reionization From a Gamma-ray Burst in a Low Hydrogen Column Density Environment
R. Chornock, E. Berger, D. B. Fox +3
We present the discovery and subsequent spectroscopy with Gemini-North of the optical afterglow of the Swift gamma-ray burst (GRB) 140515A. The spectrum exhibits a well-detected co…
Caltech Core-Collapse Project (CCCP) Observations of Type II Supernovae: Evidence for Three Distinct Photometric Subtypes
Iair Arcavi, Avishay Gal-Yam, S. Bradley Cenko +12
We present R-Band light curves of Type II supernovae (SNe) from the Caltech Core Collapse Project (CCCP). With the exception of interacting (Type IIn) SNe and rare events with long…
A glimpse of the end of the dark ages: the gamma-ray burst of 23 April 2009 at redshift 8.3
N. R. Tanvir, D. B. Fox, A. J. Levan +59
It is thought that the first generations of massive stars in the Universe were an important, and quite possibly dominant, source of the ultra-violet radiation that reionized the hy…
