Numerous metrics exist to quantify the dynamical state of galaxy clusters, both observationally and within simulations. Many of these correlate strongly with one another, but it is not clear whether all of these measures probe the same intrinsic prop...

Correcting for the overabundance of low-mass quiescent galaxies in semi-analytic models (2024)
Journal Article
Harrold, J. E., Almaini, O., Pearce, F. R., & Yates, R. M. (2024). Correcting for the overabundance of low-mass quiescent galaxies in semi-analytic models. Monthly Notices of the Royal Astronomical Society: Letters, 532(1), L61-L66. https://doi.org/10.1093/mnrasl/slae043

We compare the L-Galaxies semi-analytic model to deep observational data from the UKIDSS Ultra Deep Survey (UDS) across the redshift range 0.5 < z < 3. We find that the overabundance of low-mass, passive galaxies at high redshifts in the model can be...
