Welcome to the homepage of Martin Groenewegen.
As of February 1st, 2008 I hold a permanent position (werkleider (NL)/chef de travaux (FR)) at the Royal Observatory of Belgium in Brussels.
Between 1 Oct. 2001 and 31 Jan. 2008 I worked for the Herschel-PACS ICC (Instrument Control Centre) at
the Instituut voor Sterrenkunde (IvS) of the University of Leuven.
Between 1 Oct. 2000 and 30 Sep. 2001 I was an associate in the
ESO Imaging Survey (EIS)-team.
Before that (1 Oct. 1995 to 30 Sep. 2000) I held a post-doc position at the
(Max-Planck-Institut für Astrophysik) in Garching.
Between 1 Nov. 1993 and 30 Sep. 1995, I was a post-doc at the
(Institut d'Astrophysique de Paris).
I obtained my PhD on 28 September 1993 from the
University of Amsterdam.
In the pleasant company of Mathias Schultheis and Susanne Höfner.
Dinner party at the workshop "Future directions in AGB research,
on the occasion of the retirement of Harm Habing" in Leiden,
The Netherlands, 10/11 April 2003. Picture taken by Ian Glass (SAAO).
Myself, Maurizio Salaris, Achim Weiss (front row, right to left), happy co-organisers of
"The Giant Branches"
workshop at the Lorentz Center in Leiden, May 11-15, 2009, and most of the other participants.
- Circumstellar matter in late stages of stellar evolution, like
- Asymptotic Giant Branch stars, Post-AGB stars, and Planetary Nebulae
- Carbon stars, Miras, Semi-Regular variables and Supergiants
- The evolution of late-type stars
- AGB population synthesis
- AGB stars in the Magellanic Clouds, and the Local Group
- Modelling the dust and gas emission in the circumstellar envelopes
- The mass-loss phenomenon
- The Lutz-Kelker and other biases in trigonometric parallax (Hipparcos ) data.
- Cepheids, RR Lyrae stars & Eclipsing Binaries and the distance scale in the Universe.
- Star-Galaxy separation, and using deep extra-galactic surveys to study Galactic structure
I am the PI. of a Herschel Guaranteed Time Key Program in the domain of post-main-sequence objects,
called MESS (Mass-loss of Evolved StarS).
PACS stands for
"Photodetector Array Camera & Spectrometer" and is one of three
instruments that flies on the
space mission since 2009.
PACS performs imaging spectroscopy and imaging photometry in the
57 - 210 micron wavelength range.
The Max-Planck-Institut für Extraterrestrische Physik is the
PI-Institute with the University of Leuven (together with IMEC in Leuven and CSL in Liege) as a
Co-I institute (Co-PI: Prof. Christoffel Waelkens, KUL) at the 20% level.
Somewhere in Vienna,
I am one of the co-I's of the VISTA Magellanic Cloud
(VMC ) survey. This
survey is led by Maria-Rosa Cioni (University of Hertfordshire), and aims at observing 180 square
degrees of the Small and Large Magellanic Clouds, the bridge and stream
in three filters (YJK).
The main aims are to determine the spatially resolved star formation
history of the Magellanic system, study the (past) interaction, and to determine a 3D picture of it.
My interest is in the late-type stellar component, and study the mass-loss process
as a function of environment.
- Euro-VO Scientific Advisory Committee (2009 - present)
- Coordinator of the Belgian Guaranteed Time on ESO's VLTI Sub-Array (VISA) (June 2005 - present)
- Member of the Belgian National ESO committe (BNEC) (June 2002 - present)
- Belgian representative in the ESO User Committee (2009 - 2012)
- Belgian representative in the ESO OPC for periods 73-77.
Member of the ESO OPC for period 78. Panel member for ESO period 80.
Vice-Chair of one of the "stellar" sub-panels in periods 73-78, 80.
