From Rare Events to a Population: Discovering Overlooked Extragalactic Magnetar Giant Flare Candidates in Archival Fermi Gamma-ray Burst Monitor Data
Aaron C. Trigg, Eric Burns, Michela Negro +16
Magnetar giant flares (MGFs) are rare, extremely bright bursts of gamma-rays from highly magnetized neutron stars. These events are challenging to identify because, at extragalacti…
Implications of Joint Spectral Analysis of Gamma-Ray Bursts detected by Fermi Large Area Telescope and Gamma-ray Burst Monitor on Phenomenological Correlations
T. K. M. Aldowma, S. Razzaque, R. Martinelli +6
Gamma-ray bursts (GRBs) have emerged as powerful cosmological probes for exploring the distant Universe, owing to their immense luminosities and detectability at high redshifts. Se…
Probing the mass composition of TeV cosmic rays with HAWC
J. C. Arteaga-Velázquez
In this contribution, we have investigated the energy spectra of the elemental mass groups of cosmic rays for the Light (H+He), medium (C+O) and heavy (Ne-Fe) components using the…
Search for Signatures of Dark Matter Annihilation in the Galactic Center with HAWC
R. Alfaro, C. Alvarez, A. Andrés +109
We conduct an indirect dark matter (DM) search in the Galactic Center, focusing on a square region within in Galactic longitude and latutide, using 2,865 days of da…
Combined dark matter search towards dwarf spheroidal galaxies with Fermi-LAT, HAWC, H.E.S.S., MAGIC, and VERITAS
LAT Collaboration, S. Abdollahi, L. Baldini +586
Dwarf spheroidal galaxies (dSphs) are excellent targets for indirect dark matter (DM) searches using gamma-ray telescopes because they are thought to have high DM content and a low…
HAWC, VERITAS, Fermi-LAT and XMM-Newton follow-up observations of the unidentified ultra-high-energy gamma-ray source LHAASO J2108+5157
The VERITAS collaboration, C. B. Adams, P. Bangale +142
We report observations of the ultra-high-energy gamma-ray source LHAASO J21085157, utilizing VERITAS, HAWC, Fermi-LAT, and XMM-Newton. VERITAS has collected 40 hours of d…
Science Prospects for the Southern Wide-field Gamma-ray Observatory: SWGO
SWGO Collaboration, P. Abreu, R. Alfaro +303
Ground-based gamma-ray astronomy is now well established as a key observational approach to address critical topics at the frontiers of astroparticle physics and high-energy astrop…
A Systematic Search for MeV-GeV Pulsar Wind Nebulae without Gamma-ray Detected Pulsars
Jordan Eagle, Daniel Castro, Wei Zhang +3
An increasing number of pulsar wind nebulae (PWNe) are being identified in the TeV band by ground-based Imaging Air Cherenkov Telescopes such that they constitute the dominant sour…
Longtime Monitoring of TeV Radio Galaxies with HAWC
R. Alfaro, C. Alvarez, E. Anita-Rangel +85
We present the monitoring of the TeV-emitting radio galaxies M87, NGC~1275, 3C~264, and IC~310 with the High Altitude Water Cherenkov Observatory (HAWC) over a period of approximat…
Absence of TeV halos around millisecond pulsars
A. U. Abeysekara, R. Alfaro, C. Alvarez +82
TeV halos are extended very-high-energy (VHE; 0.1-100 TeV) gamma-ray emission around middle-aged pulsars. So far they have only been found around isolated pulsars, but it has been…
Extended TeV Halos May Commonly Exist around Middle-Aged Pulsars
A. Albert, R. Alfaro, C. Alvarez +81
Extended gamma-ray emission around isolated pulsars at TeV energies, also known as TeV halos, have been found around a handful of middle-aged pulsars. The halos are significantly m…
Characterizing Candidate Blazar Counterparts of the Ultra-High-Energy Event KM3-230213A
KM3NeT Collaboration, MessMapp Group, LAT Collaboration +13
High-energy astrophysical neutrinos serve as crucial messengers for understanding hadronic acceleration processes and identifying the origins of cosmic rays, with blazars among the…
