We determine the error introduced in a joint halo model analysis of galaxy-galaxy lensing and galaxy clustering observables when adopting the standard approximation of linear halo bias. Considering the Kilo-Degree Survey, we forecast that ignoring th...

The standard Λ Cold Dark Matter (ΛCDM) cosmological model provides a good description of a wide range of astrophysical and cosmological data. However, there are a few big open questions that make the standard model look like an approximation to a mor...

The dark matter halo masses of elliptical galaxies as a function of observationally robust quantities (2022)
Journal Article
Sonnenfeld, A., Tortora, C., Hoekstra, H., Asgari, M., Bilicki, M., Heymans, C., Hildebrandt, H., Kuijken, K., Napolitano, N. R., Roy, N., Valentijn, E., & Wright, A. H. (online).

Context. The assembly history of the stellar component of a massive elliptical galaxy is closely related to that of its dark matter halo. Measuring how the properties of galaxies correlate with their halo mass can therefore help to understand their e...
