211. GRB neutrino limits from AugerLili Yang, unpublished conference contribution Abstract: In this talk, I will talk about the searching for UHE neutrinos at Pierre Auger Observatory (PAO). Since no neutrino candidates is found so far. We have set the most stringent limits to point-like sources and Gamma-Ray-Bursts (GRB) of UHEν. I will also update the process of neutrino search results for PAO.
Keywords: neutrinos, Pierre Auger Observatory, GRB

212. 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.

217. Opazovanje delcev iz najmočnejših pospeševalnikov v vesolju z observatorijem Pierre AugerSamo Stanič, 2016, published scientific conference contribution abstract (invited lecture) Abstract: Kozmični žarki ekstremnih energij so delci, ki potujejo skozi vesoljska prostranstva z več deset milijonkrat večjimi energijami, kot jih dosegajo delci v pospeševalnikih na Zemlji. So izjemno pomemben vir informacij o najbolj energijskih procesih v vesolju, kjer je naše razumevanje naravnih zakonitosti še vedno zelo omejeno. V naravi so zelo redki: v povprečju v zgornje plasti Zemljine atmosfere prileti le nekaj delcev z energijami nad 1 EeV na kvadratni kilometer na stoletje, zato za študij njihovih lastnosti potrebujemo dovolj velik detektor. Trenutno največji je observatorij Pierre Auger, z mrežo 1.660 talnih detektorjev Čerenkova in 24 detektorji fluorescenčne svetlobe razprostira po 3.000 km2 argentinske pampe, kot kalorimeter pa uporablja atmosfero nad observatorijem z volumnom 45.000 km3. Vpadne smeri in energije kozmičnih žarkov pa določa na podlagi meritev plazov relativističnih sekundarnih delcev, ki nastanejo kot posledica trkov med kozmičnimi žarki in atomskimi jedri v zgornjih atmosferskih plasteh. Prispevek predstavlja raziskovalni potencial observatorija, ki izhaja iz njegove nadgradnje, ter najnovejše rezultate, pri katerih so raziskovalci iz Slovenije igrali ključno vlogo.
