Astroparticle physics with nuclear track detectors
This thesis is mainly about the search for exotic heavy particles -Intermediate Mass Magnetic Monopoles, Nuclearites and Q-balls with the SLIM experiment at the Chacaltaya High Altitude Laboratory (5230 m, Bolivia), establishing upper limits (90% CL) in the absence of candidates, which are among …

Alpha Spectroscopy in a Superheated Bubble Chamber and the Design of the PICO-500 Hydraulic Control Cart
… remains one of the most enigmatic phenomena in astroparticle physics, with compelling evidence for its existence despite a lack of explanation within the Standard Model. Even more puzzling is that it has thus far eluded direct detection via any known interaction mechanism. Weakly interacting …

Dark Matter Annihilation and the Observed Positron Excess
… of dark matter remains an unsolved mystery in astroparticle physics and cosmology. State of the art experiments are searching for dark matter using two different methods: direct detection, in which a WIMP-like particle interacts with a detector in the laboratory, and indirect detection, in …

Statistical methods for the search of high energy neutrinos from galactic sources in KM3NeT and ANTARES telescopes
Neutrino astronomy is a very young branch of astroparticle physics. More generally, at very high energies, astronomy with photons becomes useless because they are absorbed on the low energy photons from the cosmic background radiation. This limits the path length of a 10 TeV photon, for example, to …

Generic FPGA Preprocessing for Astrophysics Instruments in HLS
<p>FPGAs are widely deployed on high-energy astroparticle physics instruments to preprocess large volumes of streaming data from various sensors. Increasingly, these deployments are finding their way to space-borne instruments, where constraints on size, weight, and power (SWaP) require careful …

FROM DATA PRODUCTION TO SEARCH FOR GALACTIC COSMICRAY SOURCES WITH THE PIERRE AUGER OBSERVATORY
Astroparticle physics, at the crossroads of astrophysics and particle physics, investigates ultra-high-energy cosmic rays (UHECRs), the most energetic particles known in the Universe. Despite decades of research, their origins remain elusive. These particles are detected through extensive air …

Feasibility of acoustic neutrino detection with the South Pole Acoustic Test Setup
Current experiments in astroparticle physics span over more than 13 orders of magnitude in energy and 28 orders of magnitude in flux. They make use of the detection of all types of messengers in order to learn more about the sources of these cosmic rays, the properties of the interstellar medium, …

Stabilizing energy reconstructions of the surface detector at the Pierre Auger Observatory
At the Pierre Auger Observatory, ultra-high energy cosmic rays are measured through indirect measurements of the extensive air showers they induce. Accordingly, an energy reconstruction process must be undertaken. For the surface detector, the models utilized for energy reconstruction are empirical …
