TalkCosmology on small scales: the structure of (mostly) dark matter halosThe standard model of cosmology -- the ``Lambda cold dark matter'' model -- is based on the idea that the dark matter is a collisionless elementary particle...

PublicationDensity weighted angular redshift fluctuations: a new cosmological observableWe propose the use of angular fluctuations in the galaxy redshift field as a new way to extract cosmological information in the Universe. This new probe $\delta...

PublicationDetection of Gravitational Redshift in Open Cluster Nondegenerate StarsA key observational prediction of Einstein's Equivalence Principle is that light undergoes redshift when it escapes from a gravitational field. Although...

PublicationDwarf Galaxies with Central Cores in Modified Newtonian Dynamics GravitySome dwarf galaxies are within the Mondian regime at all radii, i.e., the gravitational acceleration provided by the observed baryons is always below the...

PublicationEuclid preparation. XXXVI. Modelling the weak lensing angular power spectrumThis work considers which higher order modeling effects on the cosmic shear angular power spectra must be taken into account for Euclid. We identified the...
