Approaching ballistic motion in 3D simulations of gamma-ray burst jets in realistic binary neutron star merger environments
Emma Dreas, Andrea Pavan, Riccardo Ciolfi +1
Context. The concomitant observation of gravitational wave and electromagnetic signals from a binary neutron star (BNS) merger in 2017 confirmed that these events can produce relat…
Particle acceleration with Magnetic Reconnection in large scale RMHD simulations: I. Current sheet identification and characterization
Matteo Nurisso, Annalisa Celotti, Andrea Mignone +1
We present a new algorithm for the identification and physical characterization of current sheets and reconnection sites in 2D and 3D large scale relativisticmagnetohydrodynamic nu…
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…
A comprehensive X-ray view of the active nucleus in NGC 4258
Alberto Masini, J. V. Wijesekera, Annalisa Celotti +1
(Abridged) We present a detailed broadband X-ray spectrum of NGC 4258, with the goal of precisely measuring the coronal luminosity and accretion flow properties of the AGN, and tra…
Toward measuring the spin of obscured supermassive black holes: a critical assessment with disk megamasers
Alberto Masini, Annalisa Celotti, Samuele Campitiello
Mass and spin are two fundamental properties of astrophysical black holes. While some established, indirect methods are adopted to measure both these properties of active galactic…
The disk-torus system in active galactic nuclei: possible evidence of highly spinning black holes
Samuele Campitiello, Annalisa Celotti, Gabriele Ghisellini +1
We study the ratio between the luminosity of the torus and that of the accretion disk, inferred from the relativistic model KERRBB for a sample of approximately 2000 luminosity…
