Authors:	Asaturyan, Z.¹ (AUTHOR), Chilingarian, A.¹ (AUTHOR)

Subjects:	Galactic cosmic rays, Atmospheric physics, Sun, Upper atmosphere, Space environment
Abstract:	The Cosmic Ray Division (CRD) of the Yerevan Physics Institute is a premier center for high-energy astrophysics, space weather research, and atmospheric physics. Operating at an altitude of 3,200 m, the Aragats Research Station provides a unique environment for continuously monitoring cosmic and atmospheric radiation. The SEVAN (Space Environment Viewing and Analysis Network) particle detector array stretches from Aragats to mountain peaks throughout Eastern Europe and Germany, promoting studies in solar physics, geophysics, and cosmic-ray interactions with Earth's atmosphere. CRD has significantly contributed to high-energy astrophysics, enhancing our understanding of galactic cosmic rays (GCR origin and acceleration mechanisms) and detecting the highest-energy solar protons. The division has also been instrumental in identifying Thunderstorm Ground Enhancements (TGEs) and their connection to atmospheric electric fields, linking cosmic ray physics with atmospheric electricity. Beyond traditional cosmic ray studies, CRD has pioneered AI-driven data analysis techniques that enhance gamma-ray purification in atmospheric Cherenkov imaging and reconstruct the primary cosmic-ray composition in extensive air shower experiments. Integrating machine learning, multivariate analysis, and real-time monitoring has significantly improved the accuracy of cosmic ray and space weather models. With 80 years of continuous operation, Aragats is one of the world's longest-running cosmic ray monitoring stations. It plays a vital role in interdisciplinary research at the intersection of astrophysics, geophysics, and atmospheric science. [ABSTRACT FROM AUTHOR]
