246. High Energy AstrophysicsLili Yang, unpublished conference contribution Abstract: I was invited as a lecturer at the Sumer School on Astrophysics and Astroparticles in Petnica Serbia. I gave talks on "High Energy Astrophysics", where I mainly focused on the production, propagation and detection of high energy astroparticles. Especially, I introduced the current experiments and technique and facilities. Keywords: High-energy astroparticles, experiments, detection, production Published in RUNG: 06.12.2016; Views: 5608; Downloads: 0 This document has many files! More... |
247. High Energy Emission from Gamma Ray BurstsLili Yang, invited lecture at foreign university Abstract: Gamma Ray Bursts (GRBs) are the most energetic explosions in the universe, and they have been proposed as the most promising candidate sources of ultra-high energy cosmic rays (UHECRs). As a result of interactions of UHECR within the host environment and during their propagation towards Earth, high energy neutrinos and photons are also expected from both prompt and afterglow emission. In this talk, I will review the standard theory of particle acceleration and production in a GRB fireball, and multi-wavelength and multi-messeger observations of GRB emission. I will present the prediction of PeV — EeV neutrino production and evidence of GeV gamma ray radiation, and the expected detection in IceCube, Pierre Auger Observatory and CTA (the next generation of Imaging Atmospheric Cherenkov Telescopes). The investigation of high-energy particles will provide insight into the nature and complicated mechanisms of GRBs.

248. High-energy Astroparticle DetectionLili Yang, invited lecture at foreign university Abstract: Astroparticle Physics has evolved as a new interdisciplinary field at the intersection of particle physics, astronomy and cosmology, addressing some of the most fundamental questions of contemporary physics. As the cosmic messengers, neutrinos, cosmic rays, gamma rays and also gravitational waves, take the information from the universe to tell us more about the story. Physicists have been developing experiments to detect and study these messengers. I would like to talk about the basic ideas and searching results from the dedicate cosmic ray detector Pierre Auger Observatory and also the future performance of Cherenkov Telescope Array (CTA), the next-generation ground based telescope array. CTA will play an very important role in detecting GeV-TeV gamma rays and represents the era of precision gamma ray astronomy. The multi-messenger and multi-wavelength study with various messengers are the main field in astrophysics.
