Prompt and Afterglow Constraints on the Central Engine of GRB 240825A
Daban Mohammed Saeed, Rahim Moradi, Chen-Wei Wang +2
GRB 240825A shows unprecedented temporal and spectral features that constrain the properties of its inner engine: (1) a prompt emission three-component spectrum consisting of a Ban…
The afterglow of gamma-ray burst - supernova connections
Marco Muccino, Rahim Moradi, Yu Wang
The X-ray afterglow of several long gamma-ray bursts (LGRBs) associated with broad line type Ib/c supernovae (SNe) exhibits a standard non-thermal afterglow, commonly attributed to…
Numerical analysis of quasiperiodic oscillations in the Hartle-Thorne spacetime
K. Boshkayev, T. Konysbayev, Ye. Kurmanov +2
We numerically analyze quasiperiodic oscillations (QPOs) using a well-established spacetime model with neutron star sources. Within the framework of general relativity, we present…
Quasi-periodic oscillations in rotating and deformed spacetimes
Kuantay Boshkayev, Talgar Konysbayev, Yergali Kurmanov +2
Quasi-periodic oscillation (QPOs) analysis is important for understanding the dynamical behavior of many astrophysical objects during transient events such as gamma-ray bursts, sol…
Quasi-periodic oscillations for spherically symmetric regular black holes
Kuantay Boshkayev, Anuar Idrissov, Orlando Luongo +1
We consider the recent data sets of quasi-periodic oscillations from eight different low mass X-ray binaries. We here interpret their physical features in the context of given regu…
A roadmap to gamma-ray bursts: new developments and applications to cosmology
Orlando Luongo, Marco Muccino
Gamma-ray bursts are the most powerful explosions in the universe and are mainly placed at very large redshifts, up to . In this short review, we first discuss gamma-ray…
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}…
Addressing the circularity problem in the correlation of Gamma-Ray Bursts
Lorenzo Amati, Rocco D'Agostino, Orlando Luongo +2
We here propose a new model-independent technique to overcome the circularity problem affecting the use of Gamma-Ray Bursts (GRBs) as distance indicators through the use of $E_{\rm…
On the role of the Kerr-Newman black hole in the GeV emission of long gamma-ray bursts
R. Ruffini, R. Moradi, J. A. Rueda +13
X-ray Flashes (XRFs), binary-driven hypernovae (BdHNe) are long GRB subclasses with progenitor a CO, undergoing a supernova (SN) explosion and hypercritically accretin…
On the Short GRB GeV emission from a Kerr Black hole
R. Ruffini, M. Muccino, Y. Aimuratov +10
It has recently become clear that in both short and long gamma-ray bursts (GRBs) it coexists a sequence of different events, each characterized by specific physical processes and c…
Fundamental Frequencies in the Schwarzschild Spacetime
K. A. Boshkayev, M. Muccino, J. A. Rueda +1
We consider the Keplerian, radial and vertical fundamental frequencies in the Schwarzschild spacetime to study the so-called kilohertz quasi-periodic oscillations from low-mass X-r…
On the ultra-relativistic Prompt Emission (UPE), the Hard and Soft X-ray Flares, and the extended thermal emission (ETE) in GRB 151027A
R. Ruffini, L. Becerra, C. L. Bianco +12
We analyze GRB 151027A within the binary-driven hypernova (BdHN) approach, with progenitor a carbon-oxygen core on the verge of a supernova (SN) explosion and a binary companion ne…
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…
GRB 081024B and GRB 140402A: two additional short GRBs from binary neutron star mergers
Y. Aimuratov, R. Ruffini, M. Muccino +6
Theoretical and observational evidences have been recently gained for a two-fold classification of short bursts: 1) short gamma-ray flashes (S-GRFs), with isotropic energy $E_{iso}…
Early X-ray Flares in GRBs
R. Ruffini, Y. Wang, Y. Aimuratov +17
We analyze the early X-ray flares in the GRB "flare-plateau-afterglow" (FPA) phase observed by Swift-XRT. The FPA occurs only in one of the seven GRB subclasses: the binary-driven…
On the universal late X-ray emission of binary-driven hypernovae and its possible collimation
G. B. Pisani, R. Ruffini, Y. Aimuratov +8
It has previously been discovered that there is a universal power law behavior exhibited by the late X-ray emission (LXRE) of a "golden sample" (GS) of six long energetic GRBs, whe…
GRB 090510: a genuine short-GRB from a binary neutron star coalescing into a Kerr-Newman black hole
R. Ruffini, M. Muccino, Y. Aimuratov +9
In a new classification of merging binary neutron stars (NSs) we separate short gamma-ray bursts (GRBs) in two sub-classes. The ones with erg coalesce to f…
