Weak Lensing–X-ray Scaling Relations for a High Redshift Galaxy Clusters Sample
(2017-07-21)
Accurate cosmology through large X-ray selected galaxy cluster samples will rely on accurate mass estimates and well-calibrated mass-observable relations. The comparison of independent approaches, such as X-ray and ...
Exploring Radio Pulsars With New Technologies
(2017-04-03)
Pulsars are rapidly-rotating, highly-magnetized compact neutron stars. Their strong gravitational and magnetic fields, together with the stability of their rotations and the precision with which we can measure them using ...
Formation of low-mass helium white dwarfs orbiting binary millisecond pulsars
(2017-04-25)
Millisecond pulsars (MSPs) belong to a class of radio pulsars characterized by high rotational spin rates and low magnetic fields. These neutron stars are believed to be the end-product of binary evolution, in which an old ...
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 ......
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, ...
Binary star population synthesis: Progenitors of gravitational wave driven mergers
(2018-06-13)
The vast majority of all massive stars are born in binaries. The binarity of a star may influence its life drastically via a large variety of interactions with its companion star. Several astrophysical events, like the ...
X-Ray Studies of Galaxy Clusters and Groups: Gas Properties in the Exceptional Cases of Faint Outskirts, High Redshift and a Merging Event
(2018-01-26)
The history and evolution of the universe, the understanding of the formation of structures and the investigation of a wealth of astrophysical phenomena are the topical subjects in present-day galaxy cluster physics and ......
