Study of the Very High Energy emission of M87 through its broadband spectral energy distribution

HAWC Collaboration, R. Alfaro, C. Alvarez +63

The radio galaxy M87 is the central dominant galaxy of the Virgo Cluster. Very High Energy (VHE, TeV) emission, from M87 has been detected by Imaging Air Cherenkov Tel…

HAWC Study of the Ultra-High-Energy Spectrum of MGRO J1908+06

HAWC Collaboration, A. Albert, R. Alfaro +97

We report TeV gamma-ray observations of the ultra-high-energy source MGRO J1908+06 using data from the High Altitude Water Cherenkov (HAWC) Observatory. This source is one of the h…

Search for GeV-scale Dark Matter Annihilation in the Sun with IceCube DeepCore

R. Abbasi, M. Ackermann, J. Adams +376

The Sun provides an excellent target for studying spin-dependent dark matter-proton scattering due to its high matter density and abundant hydrogen content. Dark matter particles f…

Search for Relativistic Magnetic Monopoles with Eight Years of IceCube Data

IceCube Collaboration, R. Abbasi, M. Ackermann +380

We present an all-sky 90\% confidence level upper limit on the cosmic flux of relativistic magnetic monopoles using 2886 days of IceCube data. The analysis was optimized for monopo…

Characterization of the background for a neutrino search with the HAWC observatory

HAWC Collaboration, A. Albert, R. Alfaro +59

The close location of the HAWC observatory to the largest volcano in Mexico allows to perform a search for neutrino-induced horizontal muon and tau charged leptons. The section of…

Search for High-Energy Neutrinos from Ultra-Luminous Infrared Galaxies with IceCube

IceCube Collaboration, R. Abbasi, M. Ackermann +378

Ultra-luminous infrared galaxies (ULIRGs) have infrared luminosities , making them the most luminous objects in the infrared sky. These dust…

TeV emission of Galactic plane sources with HAWC and H.E.S.S

H. Abdalla, F. Aharonian, F. Ait Benkhali +318

The High Altitude Water Cherenkov (HAWC) observatory and the High Energy Stereoscopic System (H.E.S.S.) are two leading instruments in the ground-based very-high-energy gamma-ray d…

HAWC observations of the acceleration of very-high-energy cosmic rays in the Cygnus Cocoon

A. U. Abeysekara, A. Albert, R. Alfaro +98

Cosmic rays with energies up to a few PeV are known to be accelerated within the Milky Way. Traditionally, it has been presumed that supernova remnants were the main source of very…

HAWC Search for High-Mass Microquasars

HAWC Collaboration, A. Albert, R. Alfaro +87

Microquasars with high-mass companion stars are promising very-high-energy (VHE; 0.1-100 TeV) gamma-ray emitters, but their behaviors above 10 TeV are poorly known. Using the High…

Probing the Sea of Cosmic Rays by Measuring Gamma-Ray Emission from Passive Giant Molecular Clouds with HAWC

A. Albert, R. Alfaro, C. Alvarez +87

The study of high-energy gamma rays from passive Giant Molecular Clouds (GMCs) in our Galaxy is an indirect way to characterize and probe the paradigm of the "sea" of cosmic rays i…

Evidence that Ultra-High-Energy Gamma Rays are a Universal Feature Near Powerful Pulsars

HAWC Collaboration, A. Albert, R. Alfaro +97

The highest-energy known gamma-ray sources are all located within 0.5 degrees of extremely powerful pulsars. This raises the question of whether ultra-high-energy (UHE; 56 TeV)…
