GRB 221009A: The B.O.A.T. Burst that Shines in Gamma Rays
We present a complete analysis of Fermi Large Area Telescope (LAT) data of GRB 221009A, the brightest gamma-ray burst (GRB) ever detected. The burst emission...
Coded Aperture System performances are defined by the geometry of the code, detector pixel geometry relationship and focal length. Physical Coded Aperture...
Investigating the Blazar TXS 0506+056 through Sharp Multiwavelength Eyes During 2017-2019
The blazar TXS 0506+056 got into the spotlight of the astrophysical community in 2017 September, when a high-energy neutrino detected by IceCube (IceCube...
Kicking Time Back in Black Hole Mergers: Ancestral Masses, Spins, Birth Recoils, and Hierarchical-formation Viability of GW190521
A pair-instability supernova (PISN) prevents black hole (BH) formation from stellar collapse within the approximate mass range M ∈ [65, 130] M ⊙. However, such...
