Search for High-Energy Neutrinos from Infrared Flares

R. Abbasi, M. Ackermann, J. Adams +415

IceCube has detected a diffuse flux of high-energy astrophysical neutrinos. While its astrophysical origin is unknown, a significant neutrino emission has been observed from the ga…

Time-Integrated Searches for Sub-TeV Neutrino Sources with IceCube-DeepCore

R. Abbasi, M. Ackermann, J. Adams +418

We have developed techniques for a competitive sub-TeV time-integrated neutrino search and applied it to 11.1 years of IceCube-DeepCore data. The DeepCore subarray lowers the sensi…

IceCube neutrino point-source searches in the direction of the KM3NeT ultra-high-energy event

R. Abbasi, M. Ackermann, J. Adams +416

While still under construction, the KM3NeT Astroparticle Research with Cosmics in the Abyss (ARCA) detector recorded a 200 PeV neutrino on February 13th, 2023. This event is…

A Multiwavelength Interpretation of HESS J1857+026 Emission Using the Fermi-LAT, VERITAS, and HAWC Observatories

Jordan Eagle, Yu Chen, Ramiro Torres-Escobedo +2

We present a new study on the MeV-TeV gamma-ray origin of HESS J1857+026 using data collected from the Fermi-LAT, VERITAS, and HAWC observatories. A spatial and spectral study of H…

Constraints on axion-like particles from ultra-high-energy observations of M87 with the HAWC observatory

R. Alfaro, C. Alvarez, A. Andrés +95

In this work, we perform an indirect search for axion-like particles (ALPs) through their hypothesized mixing with photons in the presence of magnetic fields. ALPs are a well-motiv…

Constraining the Photon Intensity of Extragalactic Background Light with the HAWC Observatory for the Blazar Mrk 421

R. Alfaro, C. Alvarez, A. Andrés +79

The blazar Mrk 421 exhibits rapid variability over a wide range of timescales. Spectral differences have been observed during the different emission states of Mrk 421. During the h…
