Least singular values of Gaussian matrices with deterministic shifts
Xuanang Hu, Zeyan Song, Xinglong Wu
Let be a deterministic real square matrix and a standard Gaussian matrix. We determine $\E\smin(A+G)$, up to universal constants, in terms of the singular values of . Th…
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…
Constraints on Scalar--Tensor--Vector Gravity Theory Parameters Inferred from Quasiperiodic Oscillations
Marco Muccino, Kuantay Boshkayev, Binay Prakash Akhouri +2
We study circular geodesics of neutral test particles in the static charged solution of Scalar--Tensor--Vector Gravity (STVG), and we use the twin kilohertz quasiperiodic oscillati…
Cosmological consequences of scale-dependent Barrow-Tsallis entropy
Giuseppe Gaetano Luciano, Orlando Luongo, Marco Muccino
We investigate an extended cosmological scenario based on the Barrow-Tsallis entropy, incorporating a varying (i.e., energy-scale-dependent) anomalous dimension. This behavior is r…
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…
The macroscopic precession model of quasi-periodic oscillations for rotating compact objects
Orlando Luongo, Marco Muccino
The relativistic precession model (RPM) interprets the twin kilohertz quasi-periodic oscillations (QPOs) as geodesic frequencies of test particles orbiting in the spacetime of X-ra…
Testing dark matter density profiles based on Padé approximants of different orders
Talgar Konysbayev, Orlando Luongo, Marco Muccino +5
We investigate whether low-order Padé rational functions can be used as empirical density profiles for modeling dark matter halos from galaxy RCs. We introduce three parameterizati…
No evidence for dynamical dark energy from the Combo correlation of GRBs
Marco Muccino, Massimo Della Valle, Luca Izzo +1
Recently, the Dark Energy Spectroscopic Instrument (DESI) collaboration has presented results indicating that dark energy may exhibit dynamical behavior. Calibrated gamma-ray burst…
Tightening Cosmological Constraints Within and Beyond CDM Using Gamma-Ray Bursts Calibrated with Type Ia Supernovae
Wei Hong, Luca Izzo, Massimo Della Valle +3
Context. Gamma-ray bursts (GRBs) reach redshifts beyond Type Ia supernovae (SNe Ia) and can extend distance measurements into the early Universe, but their use as distance indicato…
