The angular structure of the GW170817 jet from prompt emission alone
R. Moradi, R. Ruffini
We determine the angular structure of the GW170817 jet by the prompt emission alone, without afterglow fitting, circumburst density or microphysical parameters. We assume that GRB…
GRB 220101A: a most energetic erg long GRB triggered by two supernovae 3.5 seconds apart
R. Ruffini, Y. Aimuratov, L. M. Becerra +10
GRB 220101A is a long GRB, with a total energy exceeding erg with a redshift and one of the largest ever high-quality multi-wavelength observational coverage,…
Energy Loss of Newborn Magnetars by Schwinger Process
Chul Min Kim, Sang Pyo Kim, Remo Ruffini +2
We investigate electron--positron pair creation through the Schwinger process in newborn magnetars with millisecond spin periods and surface dipole fields close to or above the QED…
Large Language Models for Limited Noisy Data: A Gravitational Wave Identification Study
Yixuan Li, Yuhao Lu, Yang Liu +7
This work investigates whether large language models (LLMs) offer advantages over traditional neural networks for astronomical data processing, in regimes with non-Gaussian, non-st…
Selected topics on: 1) proposal of interpreting the Crab supernova with a GRB 2) progress in identifying the seven GRBs episodes 3) the role of Sagittarius A in identifying the dark matter component (the X fermion)
R. Ruffini, C. Sigismondi, Y. Wang +10
As the fiftieth anniversary of our common effort in the field of relativistic astrophysics is approaching, we offer a new look to some of our acquired knowledge in a more complete…
Vacuum breakdown around a Kerr black hole surrounded by a magnetic field
C. Cherubini, R. Moradi, J. A. Rueda +1
We present the invariant characterization of the region where vacuum breakdown into electron-positron () pairs occurs due to an overcritical electric field, the dyadoregion…
Short GRB 090510: a magnetized neutron star binary merger leading to a black hole
J. A. Rueda, R. Ruffini, Yu Wang
We model the short gamma-ray bursts (GRB) 090510 as the product of a magnetized neutron star (NS) binary merger. Accounting for the NS critical mass constraint given by the mass of…
Evidence for Two SNe Type Triggering GRB 220101A: a Pair SN and a Rotating Magnetized Core Collapse SN
R. Ruffini, M. T. Mirtorabi, P. Chardonnet +3
The traditional interpretation of gamma ray bursts (GRBs) as originating from a single black hole has been extended by the Binary Driven Hypernova (BdHN) model, in which a GRB aris…
The long-short GRB connection
J. A. Rueda, L. Becerra, C. L. Bianco +4
Long and short gamma-ray bursts (GRBs) are thought to arise from different and unrelated astrophysical progenitors. The association of long GRBs with supernovae (SNe) and the diffe…
Kerr black hole energy extraction, irreducible mass feedback, and the effect of captured particles charge
J. A. Rueda, R. Ruffini
We analyze the extraction of the rotational energy of a Kerr black hole (BH) endowed with a test charge and surrounded by an external test magnetic field and ionized low-density ma…
Occurrence of gravitational collapse in the accreting neutron stars of binary-driven hypernovae
L. M. Becerra, F. Cipolletta, C. L. Fryer +4
The binary-driven hypernova (BdHN) model proposes long gamma-ray bursts (GRBs) originate in binaries composed of a carbon-oxygen (CO) star and a neutron star (NS) companion. The CO…
Ten Supernova-rise in Binary Driven Gamma-ray Bursts
R. Ruffini, C. L. Bianco, Liang Li +6
The observation of a gamma-ray burst (GRB) associated with a supernova (SN) coincides remarkably with the energy output from a binary system comprising a very massive carbon-oxygen…
The role of the irreducible mass in repetitive Penrose energy extraction processes in a Kerr black hole
R. Ruffini, C. L. Bianco, M. Prakapenia +3
The concept of the irreducible mass () has led to the mass-energy () formula of a Kerr black hole (BH), in turn leading to its surface area . Th…
On the formation of compact-object binaries from binary-driven hypernovae
L. M. Becerra, C. L. Fryer, J. A. Rueda +1
We present smoothed-particle-hydrodynamics (SPH) simulations of the binary-driven hypernova (BdHN) scenario of long gamma-ray bursts (GRBs), focusing on the binary stability during…
Baryon-induced collapse of dark matter cores into supermassive black holes
C. R. Arguelles, J. A. Rueda, R. Ruffini
Non-linear structure formation for fermionic dark matter particles leads to dark matter density profiles with a degenerate compact core surrounded by a diluted halo. For a given fe…
Galactic Center constraints on self-interacting sterile neutrinos from fermionic dark matter ("ino") models
R. Yunis, C. R. Argüelles, N. E. Mavromatos +5
The neutrino minimal standard model (MSM) has been tightly constrained in the recent years, either from dark matter (DM) production or from X-ray and small-scale observations. H…
