We report on the detection by Swift of GRB 080913, and subsequent optical/near-infrared follow-up observations by GROND, which led to the discovery of its...
GRB 161219B/SN 2016jca: A low-redshift gamma-ray burst supernova powered by radioactive heating
Since the first discovery of a broad-lined type Ic supernova (SN) with a long-duration gamma-ray burst (GRB) in 1998, fewer than fifty GRB-supernovae (SNe) have...
GRB 201015A and the nature of low-luminosity soft gamma-ray bursts
GRB 201015A is a peculiarly low luminosity, spectrally soft gamma-ray burst (GRB), with T 90 = 9.8 ± 3.5 s (time interval of detection of 90 per cent of photons...
GRB 221009A: The B.O.A.T. Burst that Shines in Gamma Rays
We present a complete analysis of Fermi Large Area Telescope (LAT) data of GRB 221009A, the brightest gamma-ray burst (GRB) ever detected. The burst emission...
GRB010222: Afterglow emission from a rapidly decelerating shock
The GRB010222 optical and near-infrared (NIR) afterglow was monitored at the TNG and other Italian telescopes starting ~ 1 day after the high-energy prompt...
Gamma-ray bursts (GRBs) are produced by rare types of massive stellar explosion. Their rapidly fading afterglows are often bright enough at optical wavelengths...
GRB 081007 and GRB 090424: The Surrounding Medium, Outflows, and Supernovae
We discuss the results of the analysis of multi-wavelength data for the afterglows of GRB 081007 and GRB 090424, two bursts detected by Swift. One of them, GRB...
Green Bank Telescope Zpectrometer CO(1-0) Observations of the Strongly Lensed Submillimeter Galaxies from the Herschel ATLAS
The Herschel Astrophysical Terahertz Large Area Survey (H-ATLAS) has uncovered a population of strongly lensed submillimeter galaxies (SMGs). The Zpectrometer...
Green's Functions for Far-Side Seismic Images: A Polar-Expansion Approach
We have computed seismic images of magnetic activity on the far surface of the Sun by using a seismic-holography technique. As in previous works, the method is...
