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…

Pulsars in a Bubble? Following Electron Diffusion in the Galaxy with TeV Gamma Rays

H. Fleischhack, A. Albert, C. Alvarez +32

TeV Halos, extended regions of TeV gamma-ray emission around middle-aged pulsars, have recently been established as a new source class in gamma-ray astronomy. These halos have been…

All-Sky Measurement of the Anisotropy of Cosmic Rays at 10 TeV and Mapping of the Local Interstellar Magnetic Field

HAWC Collaboration, A. U. Abeysekara, R. Alfaro +400

We present the first full-sky analysis of the cosmic ray arrival direction distribution with data collected by the HAWC and IceCube observatories in the Northern and Southern hemis…

MAGIC and Fermi-LAT gamma-ray results on unassociated HAWC sources

M. L. Ahnen, S. Ansoldi, L. A. Antonelli +336

The HAWC Collaboration released the 2HWC catalog of TeV sources, in which 19 show no association with any known high-energy (HE; E > 10 GeV) or very-high-energy (VHE; E > 300 GeV)…

Searching for Dark Matter Sub-structure with HAWC

A. U. Abeysekara, A. Albert, R. Alfaro +75

Simulations of dark matter show a discrepancy between the expected number of Galactic dark matter sub-halos and how many have been optically observed. Some of these unseen satellit…

Very high energy particle acceleration powered by the jets of the microquasar SS 433

HAWC Collaboration, A. U. Abeysekara, A. Albert +104

SS 433 is a binary system containing a supergiant star that is overflowing its Roche lobe with matter accreting onto a compact object (either a black hole or neutron star). Two jet…
