The impact of binary interaction on the main-sequence morphology of young star clusters
(2022-03-04)
Star clusters play a vital role in our understanding of stellar physics and evolution, because they are believed to contain stars born at the same time, with the same initial conditions. Therefore, the distribution of the ...
Novel Search Techniques to Detect Pulsar Black Hole Binaries in Radio Observations
(2022-02-21)
Pulsars are rapidly rotating highly magnetised neutron stars that emit beams of electromagnetic radiation from their magnetic poles. These compact objects are unique as they are one of the densest forms of matter known in ...
Optical confirmation and weak lensing mass constraints for distant Sunyaev-Zel'dovich-detected galaxy clusters
(2022-03-28)
Galaxy clusters reside in the densest regions of the large-scale matter distribution of the Universe. Therefore, their number density as a function of mass and redshift is a powerful tool for cosmological studies aiming, ...
A LAsMA Survey of the Milky Way: Effects of Feedback on Molecular Clouds
(2022-09-02)
The advent of radio and (sub) millimetre astronomy has opened the world of molecular clouds (MCs) to astronomers' wonder. At the turn of the 21st century, MC surveys have helped us better understand them. How MCs form, ...
Molecular gas in hydrodynamical simulations of galaxy formation
(2022-09-26)
Observations of nearby galaxies indicate a strong correlation between their molecular gas content and their star formation rate. This leads to the conclusion that molecular hydrogen – the most abundant molecule in galaxies ...
Evolution of short-period massive binary stars in the Magellanic Clouds
(2022-10-14)
Massive stars tend to form in close binaries that will interact during their lifetime. Up to one-third of them are so close that they undergo mass transfer during hydrogen burning and yield most of the observable ...
High redshift galaxy groups as seen by Athena
(2022-01-03)
The first massive galaxy groups in the Universe are predicted to have formed at redshifts well beyond two. Baryonic physics, like stellar and active galactic nuclei (AGN) feedback in this very active epoch, are expected ...
Enabling wide-field, high-spatial-resolution fast transient searches on modern interferometry
(2022-04-13)
Fast transients reveal the energetic universe to us. They are usually the products of rapid and enormous energy releases. To study the physical nature behind them, we must know the subtle temporal structure of the signal ...
Molecular diversity in early stage high-mass protostars
(2022-11-30)
During star formation, the molecular gas undergoes significant chemical evolution with the emergence of dense cores harboring hot cores and hot corinos, rich in complex organic molecules (COMs). The formation pathways, ...
Unraveling Molecular Gas Conditions across Nearby Galaxies with CO Isotopologues
(2022-12-07)
In general, we associate large spatial scales, heavy massive objects, and great distances with the scientific study of Astronomy. However, in this thesis, we study the tiny hydrogen molecule, H2, which populates ......
