The tidal evolution of dark matter substructure -- II. The impact of artificial disruption on subhalo mass functions and radial profiles
Sheridan B. Green, Frank C. van den Bosch, Fangzhou Jiang
Several recent studies have indicated that artificial subhalo disruption (the spontaneous, non-physical disintegration of a subhalo) remains prevalent in state-of-the-art dark matt…
SatGen: a semi-analytical satellite galaxy generator -- I. The model and its application to Local-Group satellite statistics
Fangzhou Jiang, Avishai Dekel, Jonathan Freundlich +5
We present a semi-analytic model of satellite galaxies, SatGen, which can generate large samples of satellite populations for a host halo of desired mass, redshift, and assembly hi…
Scatter in Sunyaev--Zel'dovich effect scaling relations explained by inter-cluster variance in mass accretion histories
Sheridan B. Green, Han Aung, Daisuke Nagai +1
X-ray and microwave cluster scaling relations are immensely valuable for cosmological analysis. However, their power is limited by astrophysical systematics that bias mass estimate…
Dynamical self-friction: how mass loss slows you down
Tim B. Miller, Frank C. van den Bosch, Sheridan B. Green +1
We investigate dynamical self-friction, the process by which material that is stripped from a subhalo torques its remaining bound remnant, which causes it to lose orbital angular m…
The tidal evolution of dark matter substructure -- I. Subhalo density profiles
Sheridan B. Green, Frank C. van den Bosch
Accurately predicting the abundance and structural evolution of dark matter subhaloes is crucial for understanding galaxy formation, modeling galaxy clustering, and constraining th…
Using X-Ray Morphological Parameters to Strengthen Galaxy Cluster Mass Estimates via Machine Learning
Sheridan B. Green, Michelle Ntampaka, Daisuke Nagai +4
We present a machine learning approach for estimating galaxy cluster masses, trained using both Chandra and eROSITA mock X-ray observations of 2,041 clusters from the Magneticum si…
