Optical flashes, reverse shocks and magnetization (2009)
Gomboc, Andreja, Kobayashi, Shiho, Mundell, Carole G., Guidorzi, Cristiano, Melandri, Andrea, Steele, Iain A., ...
Despite the pre-Swift expectation that bright optical flashes from reverse shocks would be prevalent in early-time afterglow emission, rapid response observations show this not to be the case....
Broadband observations of the naked-eye y-ray burst GRB 080319B (2008)
Racusin, Judith L., Karpov, S. V., Sokolowski, M., Granot, Jonathan, Wu, Xiao Feng, Pal'shin, V., ...
Long-duration y-ray bursts (GRBs) release copious amounts of energy across the entire electromagnetic spectrum, and so provide a window into the process of black hole formation from the collapse of...

Anatomy of a dark burst - the afterglow of GRB 060108 (2007)
Oates, Samantha R., Mundell, Carole G., Piranomonte, Silvia, Page, Kim L., De Pasquale, Massimiliano, Monfardini, Alessandro, ...
We report the first detection of an optical afterglow of a GRB (060108) that would have been classified as 'dark' in the absence of deep, rapid ground-based optical imaging with the 2-m robotic...
Swift GRBs: The early afterglow spectral energy distribution (2007)
Tagliaferri, Gianpiero, Malesani, Daniele, Vergani, Susanna D., Campana, Sergio, Chincarini, Guido, Covino, Stefano, ...
We present the first results of a program to systematically study the optical-to-X-ray spectral energy distribution (SED) of Swift GRB afterglows with known redshift. The goal is to study the...
On the consistency of the peculiar GRBs 060218 and 060614 with the Ep,i - Eiso correlation (2007)
Amati, Lorenzo, Della Valle, Massimo, Frontera, Filippo, Malesani, Daniele, Guidorzi, Cristiano, Montanari, Enrico, ...
We analyze and discuss the position of GRB 060218 and GRB 060614 in the Ep,i - Eiso plane. GRB 060218 is important because of its similarity with GRB 980425, the proto-type event of the GRB-SN...
The Remarkable Afterglow of GRB 061007: Implications for Optical Flashes and GRB Fireballs (2007)
Mundell, Carole G., Melandri, Andrea, Guidorzi, Cristiano, Kobayashi, S., Steele, I.A., Malesani, Daniele, ...
We present a multiwavelength analysis of Swift GRB 061007. The 2-m robotic Faulkes Telescope South (FTS) began observing 137 s after the onset of the gamma-ray emission, when the optical counterpart...
Early Optical Polarization of a Gamma Ray Burst Afterglow (2007)
Mundell, Carole G., Steele, Iain A., Smith, Robert J., Kobayashi, Shiho, Melandri, Andrea, Guidorzi, Cristiano, ...
We report the optical polarization of a gamma ray burst (GRB) afterglow, obtained 203 seconds after the initial burst of gamma rays from GRB 060418, using a ring polarimeter on the robotic Liverpool...
We test the correlation found by Reichart et al. (2001) between time variability and peak luminosity of Gamma-Ray Bursts (GRBs). Recently Guidorzi et al. (2005) found that this still holds for a...
Montanari, Enrico, Frontera, Filippo, Guidorzi, Cristiano, Rapisarda, Massimo
A statistical study on the light curves of all the short Gamma-Ray Bursts detected with the Gamma Ray Burst Monitor (GRBM) aboard BeppoSAX is reported. Evidence for a very weak and long duration...
