  1. 165. The Crab Nebula：an electron PeVatron or super Pevatron of cosmic rays?

    Invited Talk

    Detection of 1.1 PeV photons from the Crab poses challenges to even classical electrodynamic theory and pure magnetohydrodynamics. Or, an accelerator that boosts protons to at highest energy of 30 PeV may be at the center of the nebula? LHAASO has found the most fascinating object, which was recorded as the first recognized supernova by Chinese in Song dynasty, so attractive that it may hint...

    Invited Talk

    Recurrent Novae (RNe) are known to experience multiple eruptions in the form of thermonuclear explosions, due to the accumulation of material accreted by a white dwarf from a binary companion star.
    The well known RN RS Ophiuchi (RS Oph) underwent its latest eruption in 2021 and triggered numerous follow-up observations world wide, including with the High Energy Stereoscopic System...

    Contributed Talk

    RS Ophiuchi (RS Oph) is a symbiotic recurrent nova that shows eruptive events roughly every 15 years. On August 8th, 2021, RS Oph erupted with its latest outburst. This event was detected by a wide range of multi-wavelength (MWL) instruments from radio up to very-high-energy (VHE) gamma rays. The MAGIC telescopes followed up on optical and high-energy triggers and initiated an observation...

  4. 91. Pursuing gamma-ray emitting pulsar wind nebulae with the Fermi-LAT
    Jordan Eagle (Goddard Space Flight Center)

    Contributed Talk

    Pulsars are rapidly rotating neutron stars that descend from a core collapse supernova and can generate pulsar wind nebulae (PWNe) through the expenditure of their rotational energy. PWNe are highly magnetized particle winds and are brightly detected across the electromagnetic spectrum. Synchrotron emission from the relativistic particles is observed from the majority of these objects from...
