The time evolution of the ultraviolet habitable zone
R. Spinelli, F. Borsa, G. Ghirlanda +3
For stars hosting Circumstellar Habitable Zone (CHZ) exoplanets, we investigate the time-evolution of their ultraviolet habitable zone (UHZ), the annular region around a star where…
Insights into the physics of GRBs from the high-energy extension of their prompt emission spectra
M. E. Ravasio, G. Ghirlanda, G. Ghisellini
The study of the high-energy (MeV-GeV) part of GRBs spectrum can play a crucial role in investigating the physics of the prompt emission, but it is often hampered by low statistic…
The ultraviolet habitable zone of exoplanets
Riccardo Spinelli, Francesco Borsa, Giancarlo Ghirlanda +2
The dozens of rocky exoplanets discovered in the Circumstellar Habitable Zone (CHZ) currently represent the most suitable places to host life as we know it outside the Solar System…
A bright megaelectronvolt emission line in -ray burst GRB 221009A
Maria Edvige Ravasio, Om Sharan Salafia, Gor Oganesyan +13
The highly variable and energetic pulsed emission of a long gamma-ray burst (GRB) is thought to originate from local, rapid dissipation of kinetic or magnetic energy within an ultr…
Subarcsecond view on the high-redshift blazar GB 1508+5714 by the International LOFAR Telescope
A. Kappes, P. R. Burd, M. Kadler +14
Studies of the most distant AGNs allow us to test our current understanding of the physics present in radio-jetted AGNs across a range of environments. The decrease in apparent lum…
Blazar nature of high-z radio-loud quasars
Tullia Sbarrato, Gabriele Ghisellini, Gianpiero Tagliaferri +3
We report on the Swift/XRT observation and classification of eleven blazar candidates at . These sources were selected as part of a sample of extremely radio-loud quasars, in…
