GRB 071003: Broadband Follow-up Observations of a Very Bright Gamma-Ray Burst in a Galactic Halo
D. A. Perley, W. Li, R. Chornock +26
The optical afterglow of long-duration GRB 071003 is among the brightest yet to be detected from any GRB, with R ~ 12 mag in KAIT observations starting 42 s after the GRB trigger,…
GRB070610 : A Curious Galactic Transient
M. M. Kasliwal, S. B. Cenko, S. R. Kulkarni +23
GRB 070610 is a typical high-energy event with a duration of 5s.Yet within the burst localization we detect a highly unusual X-ray and optical transient, SwiftJ195509.6+261406. We…
The Troublesome Broadband Evolution of GRB 061126: Does a Grey Burst Imply Grey Dust?
D. A. Perley, J. S. Bloom, N. R. Butler +18
We report on observations of a gamma-ray burst (GRB 061126) with an extremely bright (R ~ 12 mag at peak) early-time optical afterglow. The optical afterglow is already fading as a…
Circumnuclear Star Clusters in the Galaxy Merger NGC 6240, Observed with Keck Adaptive Optics and HST
L. K. Pollack, C. E. Max, G. Schneider
We discuss images of the central ~10 kpc (in projection) of the galaxy merger NGC 6240 at H and K' bands, taken with the NIRC2 narrow camera on Keck II using natural guide star ada…
A Compact Supermassive Binary Black Hole System
C. Rodriguez, G. B. Taylor, R. T. Zavala +3
We report on the discovery of a supermassive binary black hole system in the radio galaxy 0402+379, with a projected separation between the two black holes of just 7.3 pc. This is…
VLA Polarimetry Observations of PKS 2322-123; Estimating Magnetic Fields in the Abell 2597 Cluster
L. K. Pollack, G. B. Taylor, S. W. Allen
We present 5, 8, and 15 GHz total intensity and polarimetric observations of the radio source PKS 2322-123 taken with the Very Large Array (VLA). This small (11 kpc) source is loca…
