The Astronomy and Astrophysics Section, which evolved from the former Cosmic Ray Section and the Astronomy Section at Dunsink Observatory, carries out research in a range of fields: active galactic nuclei, advanced evolution of massive stars, computational astrophysics, data mining, evolution of extragalactic systems, high-energy astrophysics, and star formation. Major areas of interest are:

• Star Formation – Prof. T. Ray
• Astroparticle Physics: Gamma Ray Astronomy, X-ray Astronomy and Neutrino Astronomy – Prof. F. Aharonian
• Particle Acceleration Theory, Interstellar Gas Dynamics and Plasma Astrophysics – Prof. L. O’C. Drury

• Forty Years Of Research in Space 1972-2012 —– Summary by Emeritus Prof Denis O’Sullivan

The work of the Astronomy & Astrophysics Section is documented in detail in the annual reports:

In association with the family of the late Professor Cormac O’Ceallaigh, the School of Cosmic Physics sponsors the O’Ceallaigh Medal awarded by the Commission on Cosmic Rays (C4) of the International Union of Pure and Applied Physics.
