Identifying potentially missed extended sources in the Fermi-LAT 4FGL Catalog using clustering analysis
Giovanni Cozzolongo, Alison M. W. Mitchell, Samuel T. Spencer +2
Many Fermi Large Area Telescope (LAT) sources remain unassociated. Some may be extended sources represented by multiple catalog entries, as found for HESS J1813-178. We search for…
Gamma-Ray Constraints on Heavy Axion-Like-Particle Decays from Fermi-LAT and H.E.S.S. Blazar Spectra
A. Acharyya, F. Aharonian, M. Backes +117
The propagation of very-high-energy (VHE; GeV) gamma rays from extragalactic sources is affected by interactions with photons of the extragalactic background light (…
The Potential for Hadronic Particle Acceleration in Galactic Pulsar Wind Nebulae
Alison M. W. Mitchell, Samuel T. Spencer
Pulsar wind nebulae (PWNe), formed when the wind originating from a rapidly rotating neutron star flows out into its surroundings, have now been observed across the electromagnetic…
Hadronic emission from the environment of the Crab Pulsar Wind Nebula by re-accelerated particles
Samuel T. Spencer, Alison M. W. Mitchell, Brian Reville
The observation of peta-electronvolt (PeV) -ray photons from the Crab Nebula by LHAASO has revitalised the possibility of a secondary population of hadrons producing the highest…
Clustering analysis of Fermi-LAT unidentified point sources
Giovanni Cozzolongo, Alison M. W. Mitchell, Samuel T. Spencer +2
The Fermi Large Area Telescope (LAT) has detected thousands of sources since its launch in 2008, with many remaining unidentified. Some of these point sources may arise from source…
Deriving pulsar pair-production multiplicities from pulsar wind nebulae using H.E.S.S. and LHAASO observations
Samuel T. Spencer, Alison M. W. Mitchell
Pulsar wind nebulae (PWNe) dominate the galactic gamma-ray sky at very high energies and they are major contributors to the leptonic cosmic ray flux. However, the question of wheth…
Detectability of Supernova Remnants with the Southern Wide-field Gamma-ray Observatory
Nick Scharrer, Samuel T. Spencer, Vikas Joshi +1
Supernova remnants (SNRs) are likely sources of hadronic particle acceleration within our galaxy, contributing to the galactic cosmic ray flux. Next-generation instruments, such as…
Multi-View Deep Learning for Imaging Atmospheric Cherenkov Telescopes
Hannes Warnhofer, Samuel T. Spencer, Alison M. W. Mitchell
This research note concerns the application of deep-learning-based multi-view-imaging techniques to data from the H.E.S.S. Imaging Atmospheric Cherenkov Telescope array. We find th…
