Galaxies in Milgromian Dynamics
(2015-02-04)
Since its first formulation in 1983, Milgromian dynamics (also known as modified Newtonian dynamics or MOND) has been very successful in predicting the gravitational potential of galaxies from the distribution of baryons ...
Dark matter halos of galaxies studied with weak gravitational lensing
(2003)
The main goal of this thesis is to investigate the dark matter halos of galaxies. Current theories of galaxy formation predict that galaxies are embedded in large dark matter halos with much larger extents than the visible ...
Various Aspects of Astroparticle Physics and the Implications for Dark Matter Searches
(2020-05-04)
Cosmic rays offer an opportunity to search for dark matter, if the latter decays or annihilates into standard model particles. In the first part of this work, we address an excess that was claimed to be seen in the cosmic ...
Can the halo model describe 2nd- and 3rd-order correlation functions of gravitational lensing consistently?
(2019-11-07)
To understand and model the distribution of and the relation between baryonic and dark matter in the Universe is one of the key challenges in contemporary astrophysics. A well-established theoretical description is given ......
Solving all the problems of our universe, one neutrino mass model at a time
(2023-12-11)
The masses and mixing in the neutrino sector can not be explained by the Standard Model (SM) of particle physics and might be a harbinger for new degrees of freedom at energies scales far above or comparable to the electroweak ...
