Probing the Magnetized Medium of Galaxies and AGNs using Wideband Radio Polarimetry
(2019-08-13)
I performed an observational study of diffuse linearly polarized synchrotron emission of a nearby galaxy and of extragalactic background sources in order to study cosmic magnetism. The speciality of my work is given by the ......
Complex organic chemistry in high-mass star forming regions
(2019-10-22)
The quest for interstellar complex organic molecules (COMs) lies at the heart of astrochemistry. One basic motivation is to figure out how the rich inventory of COMs found in meteorites and comets is connected to interstellar ...
Cosmology with the galaxy bispectrum
(2019-10-29)
The last decades witnessed huge progress in understanding the large-scale structure of the Universe. While homogeneous and isotropic on the largest scales, the matter and galaxy distributions display complex patterns on ...
Radio Continuum of Galaxies with H2O-Megamaser-Disks
(2019-11-08)
Galaxies with H2O-megamaser-disks are low luminosity active galaxies where 22GHz H2O-maser emission is detected in their accretion disk surrounding the central supermassive black hole (SMBH). Furthermore, ...
The evolution of massive stars in the Small Magellanic Cloud
(2019-03-27)
Massive stars in the early universe are born with only a small amount of heavy elements (or, 'metals’). These metal-poor massive stars played a crucial role in shaping the galaxies in the early universe. They are also the ...
Small-scale Physical and Chemical Structure of Diffuse and Translucent Molecular Clouds along the Line of Sight to the Galactic Center
(2019-05-02)
Diffuse and translucent molecular clouds constitute a large part of the molecular interstellar medium (ISM) in our Galaxy as well as in other spiral galaxies. In particular, the envelopes of giant molecular clouds (GMCs), ...
Massive filamentary clouds and their role in star formation
(2019-05-27)
Filamentary structures are ubiquitous in the interstellar medium of the Milky Way. They are observed at a large range of size-scales from ~ 1 pc within star-forming and quiescent molecular clouds to ~ 100 pc representing ...
Deep, Large Scale Surveys of Star Forming Regions throughout the Milky Way
(2019-02-04)
Star formation and the processes involved are not only important to the Milky Way as an astronomical object, but are also crucial to understand our own origin. For instance, only lower-mass stars like our own Sun have ...
