Spectral study of very high energy gamma rays from SS 433 with HAWC

R. Alfaro, C. Alvarez, J. C. Arteaga-Velázquez +78

Very-high-energy (0.1-100 TeV) gamma-ray emission was observed in HAWC data from the lobes of the microquasar SS 433, making them the first set of astrophysical jets that were reso…
