GW170817: A Short Review of the First Multimessenger Event in Gravitational Astronomy

Galaxies
The first detection of gravitational waves from the binary black merger GW150914 started the era of gravitational astronomy. The observation of the binary neutron star merger GW170817 and of its associated electromagnetic counterpart GRB 170817A started ...

A Study on the Line of Sight to Galaxies Detected at Gamma-Ray Energies

The Astrophysical Journal Letters
The large-scale universal structure comprises strands of dark matter and galaxies with large underdense volumes known as voids. We measure the fraction of the line of sight that intersects voids for active galactic nuclei (AGN) detected by Fermi Large ...

Impacts of Voids, Line-of-sight Interactions, and Local Emission Environment on the Detectability of Gamma-Ray Active Galactic Nuclei

The Astrophysical Journal
Cosmic voids may have novel effects on the propagation of high-energy photons. We consider the fraction of the line of sight that intersect voids (termed “voidiness”).

The muon content of gamma-ray showers [PDF]

The result of a calculation of the expected number of muons in gamma ray initiated and cosmic ray initiated air showers using a realistic model of hadronic collisions in an effort to understand the available experimental results and to assess the ...

Leptohadronic Multimessenger Modeling of Two High-redshift (z > 1) Neutrino Emission Blazar Candidates

The Astrophysical Journal
The blazars are one of the leading candidate sources of high-energy neutrinos. Recently, two blazars have been found to be temporally and spatially correlated with some IceCube high-energy neutrino events. The two blazars, GB6 J2113+1121 and NVSS J171822+

Search for Kink Events in Variable Fermi-LAT Blazars

The Astrophysical Journal
This study explores the detection of quasiperiodic oscillations (QPOs) in blazars as a method to identify kink events within their jets, utilizing both γ -ray and polarized light observations. Focusing on a sample of nine blazars, we analyze γ -ray light
