Search for Multi-messenger Sources of Gravitational Waves and High-energy Neutrinos with Advanced LIGO during its first Observing Run, ANTARES and IceCube
ANTARES, IceCube, LIGO +1589
Astrophysical sources of gravitational waves, such as binary neutron star and black hole mergers or core-collapse supernovae, can drive relativistic outflows, giving rise to non-th…
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…
Search for steady point-like sources in the astrophysical muon neutrino flux with 8 years of IceCube data
IceCube Collaboration, M. G. Aartsen, M. Ackermann +325
The IceCube Collaboration has observed a high-energy astrophysical neutrino flux and recently found evidence for neutrino emission from the blazar TXS 0506+056. These results open…
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…
VERITAS and Fermi-LAT observations of new HAWC sources
VERITAS Collaboration, A. U. Abeysekara, A. Archer +280
The HAWC (High Altitude Water Cherenkov) collaboration recently published their 2HWC catalog, listing 39 very high energy (VHE; >100~GeV) gamma-ray sources based on 507 days of obs…
First HAWC Observations of the Sun Constrain Steady TeV Gamma-Ray Emission
A. Albert, R. Alfaro, C. Alvarez +92
Steady gamma-ray emission up to at least 200 GeV has been detected from the solar disk in the Fermi-LAT data, with the brightest, hardest emission occurring during solar minimum. T…
Multi-messenger observations of a flaring blazar coincident with high-energy neutrino IceCube-170922A
The IceCube, Fermi-LAT, MAGIC +13
Individual astrophysical sources previously detected in neutrinos are limited to the Sun and the supernova 1987A, whereas the origins of the diffuse flux of high-energy cosmic neut…
Constraints on Minute-Scale Transient Astrophysical Neutrino Sources
M. G. Aartsen, M. Ackermann, J. Adams +331
High-energy neutrino emission has been predicted for several short-lived astrophysical transients including gamma-ray bursts (GRBs), core-collapse supernovae with choked jets and n…
Observation of Anisotropy of TeV Cosmic Rays with Two Years of HAWC
A. U. Abeysekara, R. Alfaro, C. Alvarez +98
After two years of operation, the High-Altitude Water Cherenkov (HAWC) Observatory has analyzed the TeV cosmic-ray sky over an energy range between and TeV. The HAWC d…
Search for neutrinos from decaying dark matter with IceCube
IceCube Collaboration, M. G. Aartsen, M. Ackermann +327
With the observation of high-energy astrophysical neutrinos by the IceCube Neutrino Observatory, interest has risen in models of PeV-mass decaying dark matter particles to explain…
Search for Dark Matter Gamma-ray Emission from the Andromeda Galaxy with the High-Altitude Water Cherenkov Observatory
A. Albert, R. Alfaro, C. Alvarez +97
The Andromeda Galaxy (M31) is a nearby (780 kpc) galaxy similar to our own Milky Way. Observational evidence suggests that it resides in a large halo of dark matter (DM), mak…
