High-energy Astroparticle Detection
Lili 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.

GRB neutrino limits from Auger
Lili Yang, unpublished conference contribution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.

Study of heliospheric effects on galactic cosmic ray fluxes near Earth using low energy modes of the Pierre Auger Observatory
Ahmed Saleh, 2016, published scientific conference contribution abstract

Abstract: Surface detector array (SD) of the Pierre Auger Observatory has the capability to observe variations in the flux of low energy secondary cosmic ray particles. Flux rates of low energy particles can be obtained either from particle count rates (scaler mode) or from charge distribution of the pulses (histogram mode), detected by individual water Cherenkov detectors (WCD). In scaler mode, SD is sensitive to particles that deposit energy between ∼15 MeV and ∼100 MeV in a WCD, while in histogram mode the deposited energy range can be extended up to ∼1 GeV. These two low energy detection modes are excellent tools for monitoring modulations of the galactic cosmic ray flux, related to solar activity, such as Forbush decreases (with typical duration of several hours to weeks) and Solar cycle (with a duration of several years), as they provide fluxes of cosmic rays with different energies at the same detector. In this contribution we present an analysis of the effects of space weather and space climate on low energy mode data collected by the Pierre Auger Observatory in the period between 2006 and 2013. In particular, we focus on the long term trend of the cosmic ray flux. In addition to the standard corrections for atmospheric effects such as pressure, the analysis takes into account also the corrections for the long term evolution of the response of the surface detectors. Results show good correlation of the corrected low energy mode Auger data with neutron flux measurements by the global neutron monitoring network (NMDB).
