Targeted Fast Radio Burst Searches with the Efflesberg 100-m Radio Telescope
(2021-03-24)
Fast radio bursts (FRBs) are bright, energetic, millisecond duration radio bursts of extragalactic origin. The source of FRBs still remains an open problem. Since the discovery of FRBs in 2007, over 100 FRBs have been ...
New Insights into the Milky Way Magnetic Fields through Radio Broadband Spectro-polarimetry
(2020-03-05)
Magnetic field is an essential ingredient of the interstellar medium of galaxies. In particular, an accurate characterisation of the magnetic field strength and structure of the Milky Way is crucial for complete understanding ...
Spectro-spatial observations of galaxy clusters with Planck and CCAT-prime
(2020-07-07)
The Sunyaev-Zeldovich (SZ) effect is a spectral distortion of the cosmic microwave background (CMB) caused by inverse Compton scattering of CMB photons by free electrons in the hot intracluster medium (ICM) of galaxy ...
Halo bias renormalisation
(2020-06-09)
Modern galaxy redshift surveys provide a wealth of information about the evolution of our Universe. They allow to measure both the two-dimensional position on the sky and the distance (given by the cosmological redshift) ...
Properties of relativistic jets in X-ray binaries
(2021-07-12)
X-ray binaries are stellar systems consisting of a compact object (either a neutron star or a black hole) accreting matter from a companion star. Some of the X-ray binaries form relativistic jets where plasma accelerates ...
Improved techniques for pulsar data analysis
(2021-09-29)
Pulsars are rapidly rotating, strongly magnetised neutron stars with spin periods ranging from few milliseconds to tens of seconds. They emit beams of electromagnetic radiation that are predominantly detected as periodic ...
The Transient Radio Sky: Pulsars and Fast Radio Bursts
(2021-09-17)
This thesis focuses on targeted searches of two radio transients associated with neutron stars (NS): Pulsars and Fast Radio Bursts (FRBs), and the study of their properties over different timescales. Pulsars emit beams of ...
Progenitor Stars of Hydrogen- and Helium-Deficient Astrophysical Transients
(2021-01-22)
Massive stars are among the most influential components of the Universe. They house nuclear reactions that transmute hydrogen and helium, the two elements produced with the highest abundance after the Big Bang, into heavier ...
