Antoniadis was born in Didymoteicho, Greece. He obtained his bachelor's degree in Physics from the University of Thessaloniki in 2009 and his Ph.D. in 2013 at the University of Bonn.[1] under the supervision of Michael Kramer.[2]
From 2014 to 2016 Antoniadis was a Dunlap Fellow at the Dunlap Institute for Astronomy & Astrophysics in Toronto, Canada.[3] From 2017 until 2021 he was working at the Max Planck Institute for Radio Astronomy in Bonn, Germany.[4] In 2021 he joined the Institute of Astrophysics[5] - FORTH as a tenure track researcher.[6]
In 2013 he led the team that measured the mass of the neutron star in the binary system PSR J0348+0432.[7][8][9] This measurement confirmed the existence of supermassive neutron stars and made possible a new test of Einstein's theory of general relativity. In 2016, Antoniadis together with André van Staden, a South African amateur astronomer, announced the discovery of magnetic activity on the surface of the companion star of a millisecond pulsar.[10]
In 2014, Antoniadis was awarded the Otto Hahn Medal by the Max Planck Society,[11] the Dissertation Prize of the Deutsche Physikalische Gesellschaft[12] and the Best Thesis Award from the Foundation for Physics and Astronomy in Bonn.[13] His thesis was included in the “outstanding theses” series by Springer Nature[14]
In 2016 he received the John Charles Polanyi Prize for Physics by the Council of Ontario Universities.[15]
