The Intrinsic Correlations between Prompt Emission and X-ray Flares of Gamma-Ray Bursts
UniverseX-ray flare (XRF) is a common phenomenon in the X-ray afterglow of gamma-ray bursts (GRBs). Although it is commonly believed that XRFs may share a common origin with prompt emission, i.e., the “internal” origin, the origin of XRFs is still unknown.

On Quark–Lepton Mixing and the Leptonic CP Violation
UniverseIn the absence of a Grand Unified Theory framework, connecting the values of the mixing parameters in the quark-and-lepton sector is a difficult task, unless one introduces ad hoc relations among the matrices that diagonalize such different kinds of ...

Infrared Regularization of Very Special Relativity Models
UniverseWe extend the Sim(2) invariant infrared regularization of Very Special Relativity models, that we have proposed recently, to include γ5 Dirac matrix. Then, we solve the Very Special Relativity Schwinger model, find the chiral anomaly, and clarify its ...

The Composite Spectral Energy Distribution of Quasars Is Surprisingly Universal Since Cosmic Noon
UniverseLeveraging the photometric data of the Sloan Digital Sky Survey and the Galaxy Evolution Explorer (GALEX), we construct mean/median spectral energy distributions (SEDs) for unique bright quasars in redshift bins of 0.2 and up to z≃3, after taking the ...

Sources and Radiations of the Fermi Bubbles
UniverseTwo enigmatic gamma-ray features in the galactic central region, known as Fermi Bubbles (FBs), were found from Fermi-LAT data. An energy release, (e.g., by tidal disruption events in the Galactic Center, GC), generates a cavity with a shock that expands ...
