Name: Pearse Murphy
Title: PhD student
Address: Astronomy & Astrophysics Section, 31 Fitzwilliam Place Dublin 2, Ireland
Research Interests: Large explosions on the Sun known as solar flares are some of the most energetic events in the solar system. Impacts of these flares can be seen on Earth in the form of the Aurora Borealis and Aurora Australis but also as disruptions to satellite communications and electrical grids.
I am using the Irish LOw Frequency ARray (I-LOFAR) to study radio bursts in the Sun’s atmosphere to learn more about how energy in these events is released. The REALtime Transient Acquisition Cluster (REALTA) is I-LOFAR’s telescope backend that allows us to capture data from the Sun at 5.12 μs resolution in order to search for short timescale structures in radio bursts. REALTA is complemented by the Transient Buffer Board Acquisition Cluster (TACl) which stores raw data from I-LOFAR recorded at 5 ns.
I also analyse interferometric data recorded with the LOFAR core and remote stations to study the spatial scales of radio bursts.
Biography: I completed my Leaving Certificate in 2013 at Coláiste Mhuire Mullingar. I graduated from Physics & Astrophysics at Trinity College Dublin with First Class Honours in 2017 and started my PhD under the co-supervision of Prof. Peter T. Gallagher and Dr. Eoin P. Carley. I am currently based in the School of Cosmic Physics at the Dublin Institute for Advanced Studies and can sometimes be found in the astrophysics office in the School of Physics, Trinity College Dublin.
I would like to thank the Irish Research Council for funding my PhD as part of the Government of Ireland Postgraduate Scholarship scheme.
