Can AI Understand Our Universe? Test of Fine-Tuning GPT by Astrophysical Data
Yu Wang, Shu-Rui Zhang, Aidin Momtaz +5
ChatGPT has been the most talked-about concept in recent months, captivating both professionals and the general public alike, and has sparked discussions about the changes that art…
Constraining Supernova Ia Progenitors by their Locations in Host Galactic Disc
A. A. Hakobyan, A. G. Karapetyan, L. V. Barkhudaryan
Among the diverse progenitor channels leading to Type Ia Supernovae (SNe Ia), there are explosions originating from white dwarfs with sub-Chandrasekhar masses. These white dwarfs u…
GRB-SN Association within the Binary-Driven Hypernova Model
Y. Aimuratov, L. M. Becerra, C. L. Bianco +11
The observations of supernovae (SNe) Ic occurring after the prompt emission of long gamma-ray bursts (GRBs) are addressed within the binary-driven hypernova (BdHN) model where GRBs…
The white dwarf binary merger model of GRB 170817A
J. A. Rueda, R. Ruffini, Liang Li +3
Following the GRB 170817A prompt emission lasting a fraction of a second, s of data in the X-rays, optical, and radio wavelengths have been acquired. We here present a model…
X-ray and GeV afterglows and sub-TeV emission of GRB 180720B
R. Moradi, Liang Li, J. A. Rueda +3
GRB 180720B, observed by {\it Fermi}-GBM, with redshift , isotropic energy erg, and X-ray afterglow observed by the XRT onboard the Neil G…
The morphology of the X-ray afterglows and of the jetted GeV emission in long GRBs
R. Ruffini, R. Moradi, J. A. Rueda +14
We recall evidence that long gamma-ray bursts (GRBs) have binary progenitors and give new examples. Binary-driven hypernovae (BdHNe) consist of a carbon-oxygen core (CO$_{\rm core}…
Self-similarity and power-laws in GRB 190114C
R. Ruffini, Liang Li, R. Moradi +10
Following Fermi and NOT observations, Ruffini et al. (2019b) soon identified GRB 190114C as BdHN I at z=0.424, it has been observed since, with unprecedented accuracy, [...] all th…
On the GeV emission of the type I BdHN GRB 130427A
R. Ruffini, R. Moradi, J. A. Rueda +9
We propose that the "inner engine" of a type I binary-driven hypernova (BdHN) is composed of a Kerr black hole (BH) in a non-stationary state, embedded in a uniform magnetic field…
The inner engine of GeV-radiation-emitting gamma-ray bursts
R. Ruffini, J. A. Rueda, R. Moradi +12
We motivate how the most recent progress in the understanding the nature of the GeV radiation in most energetic gamma-ray bursts (GRBs), the binary-driven hypernovae (BdHNe), has l…
Electromagnetic emission of white dwarf binary mergers
J. A. Rueda, R. Ruffini, Y. Wang +6
It has been recently proposed that the ejected matter from white dwarf (WD) binary mergers can produce transient, optical and infrared emission similar to the "kilonovae" of neutro…
On a GRB afterglow model consistent with hypernovae observations
R. Ruffini, M. Karlica, N. Sahakyan +5
We describe the afterglows of the long gamma-ray-burst (GRB) 130427A within the context of a binary-driven hypernova (BdHN). The afterglows originate from the interaction between a…
On the gamma-ray emission from 3C 120
N. Sahakyan, D. Zargaryan, V. Baghmanyan
We report the analysis of Fermi Large Area Telescope data from five years of observations of the broad line radio galaxy 3C 120. The accumulation of larger data set results in the…
Hadronic Gamma-Ray and Neutrino Emission from Cygnus X-3
N. Sahakyan, G. Piano, M. Tavani
Cygnus X-3 (Cyg X-3) is a remarkable Galactic microquasar (X-ray binary) emitting from radio to -ray energies. In this paper, we consider hadronic model of emission of -rays…
