Observation and study of giga electron volt solar energetic particles using the Milagrito extensive air shower detector
… be obtained.</p><p>Milagrito was an extensive air shower observatory which operated as a prototype for the larger Milagro instrument. It operated from February 1997 to May 1998. Although Milagrito was originally designed as a high energy (>100 GeV) water-Cherenkov gamma ray observatory, it …

Characteristics of High Energy Particle Interactions from the Study of Irregular Air Showers
… ray experiment ever constructed. It records air shower data from the interactions of primary cosmic ray particles with energies from 10<sup>18</sup>eV to beyond 10<sup>20</sup>eV. The interaction energies of these events exceed the LHC at CERN by one to two orders of magnitude. I have …

Collecting heat during the day, observing the sky at night : the use of a heliostat field near Almeria to search for cosmic gamma rays
… a central solar tower and detects photon-induced showers with an energy threshold of 250 GeV and an effective detection area of about 15000 m^2. The aim of the experiment was the search for very high energy gamma sources. This thesis describes the installation of the detector and the results of …

All-Sky Search for Very-High-Energy Emission from Primordial Black Holes and Gamma-Ray Bursts with the HAWC Observatory
… of 4,100 m above sea level, is an extensive-air-shower array sensitive to gamma rays from ~0.1 to >100 TeV that has been in operation since March of 2015. It has a wide field of view of ~2 sr at any one time and, combined with its large operational duty cycle (>95%), observes 2/3 of the sky …

Measurement of the ultra high energy cosmic ray flux from data of very inclined showers at the Pierre Auger Observatory
… energy cosmic rays from data of very inclined air showers observed with the Pierre Auger Observatory. The Pierre Auger Observatory measures extensive air showers initiated by interactions of ultra-high energy cosmic rays with Earth's atmosphere. The properties of individual cosmic rays are not …

Crab flare observations with H.E.S.S. phase II
… had to be adapted. The most prominent advanced shower reconstruction technique developed by de Naurois and Rolland, the template-based model analysis, compares real shower images taken by the Cherenkov telescope cameras with shower templates obtained using a semi-analytical model. To find the …

Investigating Extended Gamma-Ray Sources with ASTRI and CTAO: Observation, Analysis and Modelling
… discovered by LHAASO (Large High Altitude Air Shower Observatory). Dedicated simulations of the Cygnus region, the Boomerang Nebula, and SS 433 demonstrated that the Mini-Array can resolve complex morphologies, constrain emission mechanisms, and identify candidate PeVatrons in the multi-TeV …
