Former Diploma & Students

Prof. Dr. Matthias Kadler  began his work as an undergraduate student at the very- long-baseline interferometry group of the MPIfR under my supervision in 1999.

His Diploma Thesis, presented on June 20th 2002, at the Universiy of Bonn, had following topic: NGC 1052 - a study of the pc-scale twin jet 

Matthias defended his PhD Thesis on October 6th, 2005, at the Universität- Bonn (co- supervised by PD Dr. Jürgen Kerp, AIfA).  Title of the work was: Compact Radio Cores in AGN: The X-Ray Connection.  He was a member of the IMPRS for Radio and Infrared Astronomy.  Matthias' PhD was awarded with the Otto-Hahn-Medal of the Max Planck Society in 2007.

Matthias joined the NASA Goddard Space Flight Center on November 2005 as NASA postdoc.  In April 2008 he moved to the Bamberg Observatory at the Universität Nürnberg-Erlangen, Germany, as faculty staff, and since April 2011 he is Professor for Astrophysics at the University of Würzburg.

Dr. Chin Shin Chang  (張靖歆) was a graduate student under my supervision from August 2007 to October 2010 at the very-long- baseline interferometry group of the MPIfR.  She has worked on the VLBI studies of the HST1 feature in M87 as well as on the Spectral Energy Distribution of MOJAVE sources.  Those were presented in her PhD Thesis, entitled Active Galactic Nuclei throughout the Spectrum: M 87, PKS 2052-47, and the MOJAVE Sample. She was a member member of the EU project ESTRELA, coordinated from the University of Manchester, from which I was scientist in charge at the MPIfR , and the IMPRS for Astronomy and Astrophysics (formerly Radio and Infrared Astronomy).

She got her MSc Thesis at the National Tsing Hua University, Taiwan, in July 2006. 

After her defense on October 25th, 2010 at the Universität-Köln, she moved as postdoctoral fellow until 2012 to the Institute for Millimetre Radio Astronomy (IRAM) in Grenoble, France.  Afterwards she has joined the Joint ALMA observatory as postdoctoral researcher in Santiago de Chile and San Pedro de Atacama in Chile.

Dr. Christian M. Fromm  has worked from 2005 to 2013 under my supervision at the very-long-baseline interferometry group of the MPIfR. 

He got a MSc in Engineering at the Technical University of Aix-La- Chapelle, and then he joined the Astronomy program at the University of Bonn, where completed his Diploma Thesis, entitled High Resolution Studies of AGN - The 2006 Radio Flare in CTA 102 as a Test of the Shock-in-Jet Model in 2009.  His Diploma Thesis got the prize to the best Thesis in 2009 by the Förderverein of the MPIfR.

Between 2010 and late 2013 he completed his PhD Thesis on observational and simulation studies of the blazar CTA 102 during a major flare.  Those are presented at the Dissertation Spectral Evolution in Blazars - The Case of CTA 102, co-supervised by M. Perucho of the University of Valencia).  This work has been awarded with the PhD Prize of the Astronomische Gesellschaft and has been published by Springer Verlag in the series “Recognizing Outstanding Ph.D. Research”.

After a postdoctoral period at the MPIfR, Dr. Fromm moved to the  September 2013, C. Fromm moved to the Institute of Space Propulsion of the German Aerospace Center (DLR) in Lampoldhausen, Germany.  Since 2016 he joined the group of Prof. Luciano Rezzolla at the Goethe Universität Frankfurt, where he work in the framework of the BlackHoleCam Synergy Grant.

Dr. Christoph Rauch worked from 2013 to 2016 under the supervision of Prof. Dr. Andreas Eckart, myself, and Dr. Thomas P. Krichbaum at the very-long-baseline interferometry group of the MPIfR.  He completed his PhD Thesis on observations of the galactic centre with near infrared and very-long-baseline interferometry in 2016.  His work was based in the study of Sgr A* with 43 GHz VLBA observations in parallel with near infrared observations by the VLT in May 2012.  Hints to a secondary component in the morphology of the galactic centre related to a NIR flare are provided in the work and in a compelling publication entitled Wisps in the Galactic Center: Near-Infrared triggered observations of the radio source Sgr A* at 43 GHz. 

I supervised the Diploma Theses of Mr. Matthias Kadler and Mr. Christian Fromm at the University of Bonn (see above).

I have supervised Mr. Indy Leclercq from the Imperial College London as Erasmus exchange student (Physics) during his ‘Year in Europe Project’ (Very Long Baseline Interferometry Study of the Relativistic Jet in  Active Galactic Nucleus 4C+21.78) at the academic year 2010-11, as well as Mr. Shaun Nicol (Kinematic and Emission Analysis of the Relativistic Jet in the Blazar B1551+130 using VLBI Data) in the academic year 2011-12.

I supervised the BSc theses (Trabajo de fin de grado) of Mr. Enrique Sanchis Melchor entitled Superluminal Motions in Relativistic Jets in the academic year 2012-13, and of Ms. Laura Vega García with title Radio Interferometry, Relativistic Jets, and Supermassive Black Holes  in the academic year 2012-13, both at the University of Valencia.

Together with Prof. Dr. Matthias Kadler (Universität Würzburg) I co-supervised the BSc thesis by Anne-Kathrin Baczko entitled Calibration and imaging of GMVA obsevations of NGC 1052, presented at the Universität Nürnberg-Erlangen in 2012.

I co-supervised, together with Dr. Andrei P. Lobanov, the MSc thesis of Ms. Laura Vega García (entitled Physics of the parsec-scale jet in 0836+710) at the MPIfR during the academic year 2015-16, presented at the Universität Bonn. 

I also supervised the BSc theses of Ms. Joana Anna Kramer (entitled VLBA observations of TANAMI sources) and Ms. Laura Ann Busch (entitled The obscuring torus in NGC 1052) at the MPIfR, both presented at the Universität Bonn in the academic year 2016-17.

BSc & MSc Students

Guest Students

I have hosted different graduate students from the Universitat de València visiting the MPIfR for short periods, from one week to three months, such as Miguel Ángel Pérez Torres (1998 & 1999), I. Martí-Vidal (2006), S. Jiménez (2008), and R. Azulay (2015).  J. Moldón from the University of Barcelona visited the MPIfR as well on 2009.

I hosted the visit of M. Böck from the University of Erlangen-Nürnberg to the Universitat de València on 2010.

I have supervised Mr. Indy Leclercq from the Imperial College London as Erasmus exchange student (Physics) during his ‘Year in Europe Project’ during the academic year 2010-11, as well as Mr. Shaun Nicols in the academic year 2011-12.

At present, I am supervising following theses:

Ms. Anne-Kathrin Baczo (also co-supervised with Prof. Dr. Matthias Kadler), expected for mid 2019, to be presented at the Universität Köln with the preliminary title The black hole and the jet of the galaxy NGC 1052.

Mr. Felix Marc Pötzl (co-supervised with Dr. Andrei P. Lobanov), expected for 2020, in the topic The role of magnetic fields in AGN jets.

Dr. Roberto Angioni (co-supervised with Prof. Dr. Matthias Kadler at the Universität Würzburg), performed his PhD Thesis between 2015 and 2018, defended in October at the  the Universität Köln with the title TANAMI sources in the radio and in gamma rays.
