Welcome to the home of High Energy Astrophysics at University College Dublin. 

UCD has a long tradition of involvement at the forefront of high-energy gamma-ray astronomy, from the early days of the Whipple telescope to the present day, where the High Energy Astrophysics group form part of the international VERITAS Collaboration.

The VERITAS Collaboration comprises a number of academic institutes from Ireland, the United Kingdom, the United States and Canada, who are interested in the detection of and study of cosmic sources of high-energy gamma rays. This study is carried out with ground-based telescopes which utilise the imaging atmospheric Cherenkov technique to indirectly detect gamma radiation. In a continuing effort to expand the field of ground-based gamma-ray astronomy , the group have spent the last number of years constructing a state-of-the-art ground-based gamma-ray observatory (known as VERITAS - Very Energetic Radiation Imaging Technique Array System). The full VERITAS array has just recently come into operation. 

The High Energy Astrophysics Group at UCD have played an integral role in construction and operation of VERITAS, with responsibility for a number of technical projects including data acquisition, data analysis software and data quality control. The group's scientific research program focuses on a number of specific topics within high-energy astrophysics which include the monitoring of active galaxies, the search for TeV gamma-ray bursts and and the TeV gamma-ray sky survey.
