Iron K signatures from accretion disks around fermionic dark matter cores
V. Crespi, F. L. Vieyro, C. R. Argüelles +1
The fluorescent iron line and its broadening due to relativistic effects are excellent probes to study the inner part of an accretion disk and the space-time geometry near the comp…
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…
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…
Impact of stratified rotation on the moment of inertia of neutron stars
Jonas P. Pereira, Tulio Ottoni, Jaziel G. Coelho +2
Rigid (Uniform) rotation is usually assumed when investigating the properties of mature neutron stars (NSs). Although it simplifies their description, it is an assumption because w…
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…
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…
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…
MeV, GeV and TeV neutrinos from binary-driven hypernovae
Stefano Campion, Juan David Uribe-Suárez, Julio David Melon Fuksman +1
We analyze neutrino () emission channels in energetic ( erg) long gamma-ray bursts within the binary-driven hypernova model. The binary-driven hypernova progeni…
Chirping compact stars: gravitational radiation and detection degeneracy with binary systems A conceptual pathfinder for space-based gravitational-wave observatories
J. F. Rodriguez, J. A. Rueda, R. Ruffini +3
Compressible, Riemann S-type ellipsoids can emit gravitational waves (GWs) with a chirp-like behavior (hereafter chirping ellipsoids, CELs). We show that the GW frequency-amplitude…
