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 ......

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 ...

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 ...

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, ...

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 ...

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), ...

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 ...

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 ...
