A multi-messenger investigation of magnetic fields in the Local Universe

• Applicant: Professor Marcus Brüggen, Ph.D.
• Subject Area: Astrophysics and Astronomy
• Term: from 2017 to 2022
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 364282880

• Final Report Year: 2022

Final Report Abstract

This proposal funded the PhD position of Stefan Hackstein at the University of Hamburg. With Mr. Hackstein we could employ an outstanding student who had also done his Masters thesis in my group. As documented in the publication list, this spawned a series of interesting projects. At the end of the project, Mr. Hackstein moved to a postdoctoral position in Switzerland. In this work our main collaborators were Dr. Franco Vazza (Bologna) and Prof. Dr. Günter Sigl (Hamburg).
