Combined dark matter search towards dwarf spheroidal galaxies with Fermi-LAT, HAWC, H.E.S.S., MAGIC, and VERITAS
LAT Collaboration, S. Abdollahi, L. Baldini +586
Dwarf spheroidal galaxies (dSphs) are excellent targets for indirect dark matter (DM) searches using gamma-ray telescopes because they are thought to have high DM content and a low…
Extended TeV Halos May Commonly Exist around Middle-Aged Pulsars
A. Albert, R. Alfaro, C. Alvarez +81
Extended gamma-ray emission around isolated pulsars at TeV energies, also known as TeV halos, have been found around a handful of middle-aged pulsars. The halos are significantly m…
Search for joint multimessenger signals from potential galactic cosmic-ray accelerators with HAWC and IceCube
R. Alfaro, C. Alvarez, J. C. Arteaga-Velázquez +489
The origin of high-energy galactic cosmic rays is yet to be understood, but some galactic cosmic-ray accelerators can accelerate cosmic rays up to PeV energies. The high-energy cos…
Study of long-term spectral evolution and X-ray and Gamma-ray correlation of blazars seen by HAWC
R. Alfaro, C. Alvarez, A. Andrés +94
The HAWC Observatory collected 6 years of extensive data, providing an ideal platform for long-term monitoring of blazars in the Very High Energy (VHE) band, without bias towards s…
Ultra-High-Energy Gamma-Ray Bubble around Microquasar V4641 Sgr
R. Alfaro, C. Alvarez, J. C. Arteaga-Velázquez +89
Microquasars are laboratories for the study of jets of relativistic particles produced by accretion onto a spinning black hole. Microquasars are near enough to allow detailed imagi…
