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…
The physics of GRB jets and their interaction with the progenitor star
Davide Lazzati, Brian J. Morsony, Mitchell C. Begelman
It is now generally accepted that long gamma-ray bursts are associated with the final evolutionary stages of massive stars. As a consequence, their jets must propagate through the…
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…
Temporal and Angular Properties of GRB Jets Emerging from Massive Stars
Brian J. Morsony, Davide Lazzati, Mitchell C. Begelman
We study the long-term evolution of relativistic jets in collapsars and examine the effects of viewing angle on the subsequent gamma ray bursts. We carry out a series of high-resol…
