On radiative acceleration in spine-sheath structured blazar jets
Atul Chhotray, Francesco Nappo, Gabriele Ghisellini +3
It has been proposed that blazar jets are structured, with a fast spine surrounded by a slower sheath or layer. This structured jet model explains some properties of their emission…
The 999th Swift gamma-ray burst: Some like it thermal
F. Nappo, A. Pescalli, G. Oganesyan +23
We present a multiwavelength study of GRB 151027A. This is the 999th GRB detected by the Swift satellite and it has a densely sampled emission in the X-ray and optical band and has…
An unexpected new explanation of seasonality in suicide attempts: Grey's Anatomy broadcasting
Luca Perri, Om S. Salafia
Seasonality is one of the oldest and most elucidation-resistant issues in suicide epidemiological research. Despite winter depression (also known as Seasonal Affective Disorder, SA…
Light curves and spectra from off-axis gamma-ray bursts
Om S. Salafia, Gabriele Ghisellini, Alessio Pescalli +2
If gamma-ray burst prompt emission originates at a typical radius, and if material producing the emission moves at relativistic speed, then the variability of the resulting light c…
