From the Special Topic of Gamma-ray Bursts
In our Special Topic on gamma-ray burst (GRB) research over the past decade, Dr. Joshua Bloom's work ranks at #10 by total cites, based on 85 papers cited a total of 3,639 times. Five of these papers are on the lists of the 20 most-cited papers over the past decade and over the past two years.

Figures and descriptions:

Figure 1:  
Figure 1: Artist's illustration of a gamma-ray burst occurring in a dusty region of intense star formation. If a dust cloud lies between the burst and Earth, the optical light will be almost entirely absorbed, but the gamma-rays and X-rays will easily penetrate the dust. New evidence suggests that most "dark" gamma-ray bursts — those without optical afterglows — form in similar dusty environments.

Figure 2:
Figure 2: In the seconds after it first pointed at GRB 080319B, the infrared telescope PAIRITEL was blinded by the brilliant explosion (a). As the gamma-ray burst began to fade, PAIRITEL was able to track the light from the explosion for many hours (b and c). (Credit: Joshua Bloom/UC Berkeley).
 

Figure 3:
Figure 3: After the Swift satellite recorded a gamma-ray burst near this galaxy on May 5, 2006, UC Berkeley astronomers turned the Keck telescope on the region to look for an expected visible-light signature of a stellar explosion. The lack of supernova light in this and another "long" variety gamma-ray burst now casts doubt on the emerging paradigm that all long bursts accompany supernovae.
