Astronomical research
My general field of work can be described as "extragalactic
astronomy". However, usually I investigate rather nearby galaxies,
and since I mainly use radio telescopes for my studies, it's basically
the interstellar matter in these objects:
- Magnetic fields in disks and halos of galaxies
- Origin and morphology of radio halos
- Morphology and dynamics of molecular gas in galactic disks
- Cold dust in galaxies
- Physical conditions in the ISM
of external galaxies
- Molecular gas at high redshift
Responsibilities at APEX
- Preparation and observation of scientific projects at APEX in service
mode and data quality control
- Participation in the commissioning of facility receivers, backends,
software and other components
- Web-based documentation of the APEX system characteristics and support
for preparation of observations
- Astronomical calibration of LABOCA, monitoring the telescope pointing,
maintenance of system-wide source and line catalogs, and several other
smaller service tasks
Technical interests
- Software programming:
This includes the improvement of existing data reduction software,
like NIC (which is part of the
GILDAS Package),
and also some own developments, like
TkParal.
- Fast On-The-Fly Continuum Mapping:
Fast (or "undersampled") On-The-Fly Mapping is a
method for mapping large areas in a reasonable amount
of observing time using multichannel bolometer arrays. Read the SMTO
working report on
Fast OTF Mapping at the HHT
if you are interested.
- Fast Switching Phase Calibration:
As a post-doc at IRAM Grenoble, I was working on some simulations
about FSPC and its efficiency in mm-wave interferometry. Some
results of this work are available on request.
What else?
