High-Performance Computing for Astrophysical Simulations and Astroparticle Observations

Authors

Published Date

Simulations in astrophysics play a crucial role in testing models and comparing them with observational data, for which High-Performance Computing has become indispensable for handling complex scenarios. In this paper, we present two important applications in astrophysical simulations. First, we explore the adaptation of the Pencil Code to study the evolution of magnetic field configurations in stratified stars. Second, we highlight the ARTI framework developed to estimate signals at the Latin American Giant Observatory. In addition, we discuss the importance of reproducibility in scientific analysis.

LAGO researches gamma-ray bursts and space weather phenomena using water Cherenkov detectors (WCDs) deployed at different altitudes. Large-area (8-inches) photomultipliers sense Cherenkov radiation produced by secondary particles crossing the WCDs. We present a generic photomultiplier model applied to the Hamamatsu R5912 tube, used in most of LAGO’WCDs. The model depends on the number of dynodes, the bias voltage, the number of incident photons, the photodetection efficiency, and the bias network. Besides, the implementation of the model includes a simulation of the front-end of LAGO’s acquisition electronics, allowing the linearity of the system to be evaluated under different conditions. The model was validated with data recorded by the MuTe-Chitaga (Bucaramanga, Colombia) and Nahuelito (Bariloche, Argentina) WCDs. Geant4 simulations estimate the number of Cherenkov photons arriving at the photomultiplier. We contrasted the anode/dynode pulse amplitude ratio between the data and the model prediction. We also compared the estimated and measured vertical equivalent muon charge (pulse area). The vertical-muon-charge estimated by the model (321.6 UADC) differs by 4% from the …

This...Abstract: The LAGO (Latin American Giant Observatory) project is an extended Astroparticle Observatory at global scale. It is mainly oriented to basic research on three branches of Astroparticle physics: the Extreme Universe, Space Weather phenomena, and Atmospheric Radiation at ground level. This work is framed in the latter branch, its aim is to study the potential effects on extensive air showers from changes in geoelectric and geomagnetic fields, induced by the onset of seismic activity. For this purpose, simulations for flux of secondaries are performed with ARTI, a tool developed by LAGO that combines Magnetocosmics, CORSIKA, and Geant4 to account, respectively, for the propagation of a shower by a primary particle, geomagnetic corrections, and detector response. Using ARTI, we have calculated the radiation background at the LAGO Site in Universidad San Francisco de Quito (2200 masl). Regular conditions for the Earth's electromagnetic field are taken from the NCEI Geomagnetic Calculator for specific fair-weathered days above the location. Variations from this regularity are introduced based on relevant studies on seismic activity. The results show that there exists an effect on the number of secondary particles at ground level, which could, in principle, be detected by a LAGO WCD detector
