Search for TeV emission from spider millisecond pulsars with HAWC

R. Alfaro, E. Anita-Rangel, M. Araya +90

Millisecond pulsars (MSPs) are observed to emit multi-wavelength radiation, from radio to GeV. Spider MSPs, which interact with their low-mass companion in close orbit (orbital per…

HAWC Study on the Ultra-High-Energy Gamma-Ray Emissions from the Pulsar Wind Nebula G32.64+0.53

R. Alfaro, C. Alvarez, E. Anita-Rangel +108

Multi-TeV gamma-ray emission around eHWC J1850+001 (a source from the first HAWC catalog of gamma-ray sources emitting above 56 TeV) is spatially coincident with the pulsar wind ne…

Investigating IceCube Neutrino Alerts with the HAWC -Ray Observatory

The HAWC Collaboration, R. Alfaro, C. Alvarez +95

Neutrino emission from astrophysical sources has long been considered a signature of cosmic-ray acceleration. The IceCube neutrino observatory has observed a diffuse flux of TeV-Pe…

Orbital Modulation of Gamma-Rays Beyond 100 TeV from LS 5039

R. Alfaro, M. Araya, J. C. Arteaga-Velázquez +88

Gamma-ray binaries are systems composed of a compact object orbiting a massive companion star. The interaction between these two objects can drive relativistic outflows, either jet…
