Dr Patrick Reichherzer is a postdoctoral Gateway fellow in the Laboratory Astroparticle and the Plasma Theory group at the University of Oxford. He completed undergraduate studies at Karlsruhe Institute of Technology (Germany, 2016) and Masters studies at Ruhr University Bochum (Germany, 2018), for which he won the Master's thesis prize. He completed his joint PhD in Astronomy at Ruhr University Bochum and Paris-Saclay University with distinction (2022). In his thesis, he quantified the influence of propagation effects of cosmic messengers on observable multi-messenger signatures of the transient universe [1-4]. These findings highlight the need for further improved, coordinated multi-messenger observation campaigns to unravel the nature of extreme transient astrophysical events. To this end, Dr Patrick Reichherzer developed the holistic platform Astro-COLIBRI [5,6] as one step in this direction.
The key objective of his research in Oxford is to investigate the signatures of the interplay between magnetised, turbulent plasmas and cosmic rays (CRs). What can they tell us about the origin of CRs?
