Discovery of 24 radio-bright quasars at using low-frequency radio observations
A. J. Gloudemans, K. J. Duncan, A. Saxena +18
High redshift quasars () that also shine brightly at radio wavelengths are unique signposts of supermassive black hole activity in the early universe. However, bright radio so…
Spectroscopy of GRB 051111 at z=1.54948: Kinematics and Elemental Abundances of the GRB Environment and Host Galaxy
B. E. Penprase, E. Berger, D. B. Fox +8
We present a high-resolution, high signal-to-noise optical spectrum of the afterglow of GRB 051111 obtained with the HIRES spectrograph on the Keck I 10-m telescope. The spectrum e…
Fine-Structure FeII and SiII Absorption in the Spectrum of GRB 051111: Implications for the Burst Environment
E. Berger, B. E. Penprase, D. B. Fox +4
We present an analysis of fine-structure transitions of FeII and SiII detected in a high-resolution optical spectrum of the afterglow of GRB 051111 (z=1.54948). The fine-structure…
GRB 021004: a Massive Progenitor Star Surrounded by Shells
Bradley E. Schaefer, C. L. Gerardy, P. Hoflich +13
We present spectra of the optical transient of GRB021004 obtained with the Hobby-Eberly telescope starting 15.48, 20.31 hours, and 4.84 days after the burst and a spectrum obtained…
