Academic and Professional background
Michal Zajaček is a junior postdoctoral researcher in the VLBI group of the Max Planck Instute for Radio Astronomy in Bonn, Germany. He continues to be a member of the Galactic centre workgroup of Prof. Dr. Andreas Eckart at the
University of Cologne as well as an external member of the Prague Relativistic Astrophysics Group. In 2014 he was selected for the International Max Planck Research School (IMPRS)
programme. During his PhD studies he focused on the dynamics in galactic nuclei, especially the Galactic center,
which can be studied at very high resolution.
Michal is also a member of SFB956 Conditions and impact of star formation, where he is involved in the project 'Conditions for Star Formation in Nearby AGN and QSO Hosts', and a member of the StrongGravity consortium. In August 2016 he became an honourable member of the DAUP-Orion astronomical organization located in Makarska, Croatia.
Michal Zajaček obtained his bachelor degree in general physics in 2012 at the Charles
University in Prague. In his bachelor thesis "Late heavy bombardment at various places
of the Solar System" supervised by Dr. Miroslav Brož he used N-body simulations to study the dynamics
of the Solar System in its early history. In 2014 he finished
the master degree in Astronomy and Astrophysics at the same university.
The master thesis "Neutron stars near a galactic centre", which was finished under the supervision
of Prof. Vladimír Karas from Prague Relativistic Astrophysics group, dealt with the physics of compact stellar objects
near the Galactic centre, focusing on their interaction with the ambient
medium and possible observable effects. In 2014 he was also awarded
RNDr. degree (Czech Doctor of natural sciences) by defending the enlarged and
updated master thesis.
Michal has been involved on several observational as well as theoretical projects focused on the Galactic centre physics in Prof. Andreas Eckart's group at the University of Cologne. By combining models with observations he constrained the properties of near-infrared excess sources, star-formation, stellar dynamics, and the flaring activity of Sgr A*. Moreover, he has aimed at linking the Galactic centre research with the study of galaxy evolution across optical emission line diagrams. To this aim he performed observations of galaxies from the FIRST survey with the Effelsberg radiotelescope at 4.8 GHz and 10.5 GHz.
