The Royal Irish Academy/Acadamh Ríoga na hÉireann champions research. We identify and recognise Ireland’s world class researchers. We support scholarship and promote awareness of how science and the humanities enrich our lives and benefit society. We believe that good research needs to be promoted, sustained and communicated. The Academy is run by a Council of its members. Membership is by election and considered the highest academic honour in Ireland.

McCrea Lecture

Organised and hosted by the Royal Irish Academy, the McCrea lecture series is held in honour of Sir William McCrea MRIA (1904-1999), an eminent and influential astronomer. Run every two years, the McCrea Lecture is a highlight on the astronomy enthusiasts’ calendars as it is an opportunity for people from various backgrounds, disciplines and professions to come together to discuss news and progress within space science.

About the lecture

Astronomer Professor Gregg Hallinan will give a talk on ‘The Era of Multi-Messenger Astronomy’, followed by a Q&A chaired by Dr Deirdre Coffey, Assistant Professor of Astrophysics and Space Science, University College Dublin.Gregg Hallinan will introduce the topic of multi-messenger astronomy, including recent breakthroughs and future promise. He will also introduce one of the key upcoming telescopes for multi-messenger astronomy, the 2000-antenna Deep Synoptic Array (DSA-2000) radio telescope. The DSA-2000 will commence construction next year and will be the world's most powerful survey radio telescope, with a significant fraction of observing time dedicated to multi-messenger astronomy.

About the speaker

Gregg Hallinan is a Professor of Astronomy at the California Institute of Technology (Caltech) and Director of the Owens Valley Radio Observatory (OVRO). His group searches for new and variable sources that appear in the radio sky. These include the electromagnetic counterparts of gravitational wave events and the magnetospheres of exoplanets. He has led the development of a new generation of radio telescopes, optimized for time domain and multi-messenger science, including the upcoming 2000-antenna Deep Synoptic Array (DSA-2000), which will be the world's most powerful survey radio telescope. Gregg completed his PhD at the University of Galway and moved to the US as a Jansky Fellow at the University of California Berkeley before joining the faculty at Caltech in 2012. He is a recipient of a Sloan Fellowship and the 2022 New Horizons in Physics Breakthrough Prize.

About the Chair
