Veni [email protected] Amsterdam, simulating the Universe, investigating the nature of dark matter
Symposium S6 “Stellar & gas kinematics in galaxies across cosmic time, connecting observations with theory” of the virtual EAS2020 was a great success! Big thanks to all the participants! Also warm thanks to all the…
In this work, Joop Schaye and myself investigate the dependence of the local galaxy stellar-to-halo mass relation (SHMR) on galaxy morphology. We use data from the Sloan Digital Sky Survey DR7 with morphological classifications from…
In this work, recently submitted to Monthly Notices, I am analysing the observed anti-correlation between the central dark matter (DM) densities of the bright Milky Way (MW) dwarf spheroidal galaxies (dSphs) and their orbital pericenter…
Willem Kroese and Julius Hendrix have recently completed the bachelor research project at Leiden University. I have had the pleasure to be Willem & Julius’ main supervisor. The students investigated the physical origin of rejuvenation…
I have had the pleasure to be Eva van Weenen‘s main supervisor for her master research project at Leiden University. Eva has recently completed the Master degree in Data Science & Astronomy. For her thesis,…
The Dutch Research Council (NWO) has recently awarded a Veni grant worth up to 250,000 euros to me and 165 other highly promising young scientists. The grant will provide me with the opportunity to further…
The morphology of galaxies is typically characterised either by extensive visual inspection (e.g. Galaxy Zoo project, Lintott et al. 2011) or through the stellar kinematics (e.g. Emsellem et al. 2007).
Understanding the universal accretion history of dark matter haloes is the first step towards determining the origin of their structure. Previous studies have quantified halo mass accretion histories using catalogues of halos from numerical simulations,…
One of the major goals of modern galaxy formation theory is to understand the physical mechanisms that halt the star formation process, by either removing, heating or preventing the infall of cold gas onto the…
Correa C. A., Wyithe J. S. B., Schaye J., Duffy A. R., 2015c, MNRAS, 452, 1217 Over the past few years large cosmological simulations have been performed to determine the properties of dark matter haloes,…
