Accurate distances of the Galactic spiral arms from dust-scattered X-ray emission of gamma-ray bursts
B. Vaia, I. Fornasiero, A. Tiengo +5
The details of the spiral structure of the Milky Way are still debated due to large uncertainties in the distance estimates obtained through the most common tracers. X-ray dust sca…
The very high energy view of gamma-ray bursts with the MAGIC telescopes
Alessio Berti, Željka Bošnjak, Alberto Castro-Tirado +22
Gamma-ray bursts (GRBs) are one of the main targets for the observations of the MAGIC telescopes. As a result of the effort in improving the sensitivity of the instrument and the a…
Probing the interstellar medium toward GRB 221009A through X-ray dust scattering
B. Vaia, Ž. Bošnjak, A. Bracco +5
The observation of 21 X-ray dust-scattering rings around the extraordinarily bright gamma-ray burst (GRB) 221009A provides a unique opportunity to study the interstellar medium (IS…
Gamma-Ray Burst prompt emission from the synchrotron radiation of relativistic electrons in a rapidly decaying magnetic field
Frédéric Daigne, Željka Bošnjak
Synchrotron radiation from accelerated electrons above the photosphere of a relativistic ejecta is a natural candidate for the dominant process for the prompt GRB emission. There i…
