High energy astrophysics, cosmic rays/Multi-messenger
Oral presentation in parallel session
The Pierre Auger Observatory, in Argentina, has been detecting for more than 15 years
ultra-high energy cosmic rays with unprecedented statistics and data quality.
Cosmic rays showers above $10^{17}$ eV are accurately measured with a large array of surface detectors covering 3000 km2 and fluorescence telescopes.
The operation of a denser sub-array with enhanced triggers has extended...

High energy astrophysics, cosmic rays/Multi-messenger
Oral presentation in parallel session
The Telescope Array (TA) is an ultra-high energy cosmic ray detector, the largest in the Northern Hemisphere, sensitive to cosmic rays with energies from below 1 PeV to above 100 EeV. The main detector is a hybrid detector consisting of an array of 507 surface detectors covering 700 km$^2$ overlooked by three fluorescence telescope detector stations. The energy range has been extended at the...

High energy astrophysics, cosmic rays/Multi-messenger
Oral presentation in parallel session
We present the results of a search for diffuse photons with energies higher than 1 EeV based on Telescope Array surface detector data and a novel neural network event analysis technique. The results of a search for point sources of photons for all directions in the Northern hemisphere and a search for several target source classes are also presented.

High energy astrophysics, cosmic rays/Multi-messenger
Oral presentation in parallel session
The key to understand the origin of the Ultra High Energy Cosmic Ray (UHECR) is higher statistics. One of the concepts to realize the future huge observation is an array of low cost fluorescence telescopes. The fluorescence telescope can measure not only the arrival direction and energy spectrum but also the mass composition which is the important information to understand the UHECR. In order...

High energy astrophysics, cosmic rays/Multi-messenger
Oral presentation in parallel session
EEE is an extended cosmic ray observatory, composed by 59 MRPC-based tracking telescopes, spread over more than 10 degrees in latitude and longitude.
Several sites host two or more telescopes in the same town, as local clusters, capable of detecting high energy cosmic showers.
The relative distances between the 12 existing clusters range between 86 and 1200 km, allowing the search for rare...
