Jitter radiation images, spectra, and light curves from a relativistic spherical blastwave
Brian J. Morsony, Jared C. Workman, Davide Lazzati +1
We consider radiation emitted by the jitter mechanism in a Blandford-McKee self-similar blastwave. We assume the magnetic field configuration throughout the whole blastwave meets t…
X-ray flares and their relation to the inner engine activity of GRBs
Davide Lazzati, Brian J. Morsony, Rosalba Perna +1
Flares overlaid on the smooth power-law decay of Swift X-ray afterglows are rather common, appearing in roughly half the observed light curves. They are a manifestation of the late…
Jitter radiation in gamma-ray bursts and their afterglows: emission and self-absorption
Jared Workman, Brian Morsony, Davide Lazzati +1
Relativistic electrons moving into a highly tangled magnetic field emit jitter radiation. We present a detailed computation of the jitter radiation spectrum, including self-absorpt…
Gamma-Ray Burst jet dynamics and their interaction with the progenitor star
Davide Lazzati, Brian J. Morsony, Mitchell C. Begelman
The association of at least some long gamma-ray bursts with type Ic supernova explosions has been established beyond reasonable doubt. Theoretically, the challenge is to explain th…
Long Gamma-Ray Bursts as standard candles
D. Lazzati, G. Ghirlanda, G. Ghisellini +4
As soon as it was realized that long GRBs lie at cosmological distances, attempts have been made to use them as cosmological probes. Besides their use as lighthouses, a task that p…
