Observations of the Naked-Eye GRB 080319B: Implications of Nature's Brightest Explosion

J. S. Bloom, D. A. Perley, W. Li +18

The first gamma-ray burst (GRB) confirmed to be bright enough to be seen with the naked eye, GRB 080319B at redshift z = 0.937, allowed for exquisite follow-up observations across…

Towards a Real-time Transient Classification Engine

J. S. Bloom, D. L. Starr, N. R. Butler +4

Temporal sampling does more than add another axis to the vector of observables. Instead, under the recognition that how objects change (and move) in time speaks directly to the phy…

Type Ia Supernovae are Good Standard Candles in the Near Infrared: Evidence from PAIRITEL

W. Michael Wood-Vasey, Andrew S. Friedman, Joshua S. Bloom +11

We have obtained 1087 NIR (JHKs) measurements of 21 SNe Ia using PAIRITEL, nearly doubling the number of well-sampled NIR SN Ia light curves. These data strengthen the evidence tha…

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…

A Putative Early-Type Host Galaxy for GRB 060502B: Implications for the Progenitors of Short-Duration Hard-Spectrum Bursts

J. S. Bloom, D. A. Perley, H. -W. Chen +6

Starting with the first detection of an afterglow from a short-duration hard-spectrum gamma-ray burst (SHB) by Swift last year, a growing body of evidence has suggested that SHBs a…

Optical Lightcurve & Cooling Break of GRB 050502A

S. A. Yost, K. Alatalo, E. S. Rykoff +29

We present lightcurves of the afterglow of GRB050502A, including very early data at t-t_{GRB} < 60s. The lightcurve is composed of unfiltered ROTSE-IIIb optical observations from 4…

A contemporaneous infrared flash from a long gamma-ray burst: an echo from the central engine

C. H. Blake, J. S. Bloom, D. L. Starr +25

The explosion that results in a cosmic gamma-ray burst (GRB) is thought to produce emission from two physical processes -- the activity of the central engine gives rise to the high…
