Dr Justus Neumann
I am an observational astronomer working as postdoctoral research fellow at the Institute of Cosmology and Gravitation at the University of Portsmouth. Before coming to the UK, I did my PhD on secular evolution in galaxies at the Leibniz-Institut für Astrophysik Potsdam (AIP, 2015-2019) supervised by Lutz Wisotzki and Dimitri Gadotti. During that time I spent two years in Chile with an ESO studentship (2016-2018).
I am a member of the SDSS-IV/MaNGA , TIMER and CARS collaborations.
I study the structure and evolution of galaxies using large observational data sets from integral field spectrographs such as APO/BOSS, CAHA/PMAS and VLT/MUSE.
The main focus of my research is to develop a better understanding of the internal physical processes that shape galaxies, by analysing their structure, their stellar populations and their dynamics. I am particularly interested in galaxy bars: the main drivers of internal secular evolution, i.e. the evolution of galaxies in isolation.
At the ICG, I am also responsible for maintaining the full-spectral fitting code Firefly as well as the MaNGA Firefly Value-Added-Catalogue that contains stellar population parameters for ~10,000 MaNGA galaxies.
