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…
Concentrations of Dark Haloes Emerge from Their Merger Histories
Kuan Wang, Yao-Yuan Mao, Andrew R. Zentner +3
The concentration parameter is a key characteristic of a dark matter halo that conveniently connects the halo's present-day structure with its assembly history. Using 'Dark Sky', a…
Ly Blobs from Cold Streams Undergoing Kelvin-Helmholtz Instabilities
Nir Mandelker, Frank C. van den Bosch, Daisuke Nagai +3
We present an analytic toy model for the radiation produced by the interaction between the cold streams thought to feed massive halos at high redshift and their hot CGM. We begin b…
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…
Instability of Supersonic Cold Streams Feeding Galaxies IV: Survival of Radiatively Cooling Streams
Nir Mandelker, Daisuke Nagai, Han Aung +3
We study the effects of Kelvin Helmholtz Instability (KHI) on the cold streams that feed massive halos at high redshift, generalizing our earlier results to include the effects of…
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…
Cosmological Evidence Modelling: a new simulation-based approach to constrain cosmology on non-linear scales
Johannes U. Lange, Frank C. van den Bosch, Andrew R. Zentner +3
Extracting accurate cosmological information from galaxy-galaxy and galaxy-matter correlation functions on non-linear scales () requires cosmologic…
BASILISK: Bayesian Hierarchical Inference of the Galaxy-Halo Connection using Satellite Kinematics--I. Method and Validation
Frank C. van den Bosch, Johannes U. Lange, Andrew R. Zentner
We present a Bayesian hierarchical inference formalism (Basilisk) to constrain the galaxy-halo connection using satellite kinematics. Unlike traditional methods, Basilisk does not…
New perspectives on the BOSS small-scale lensing discrepancy for the Planck CDM Cosmology
Johannes U. Lange, Xiaohu Yang, Hong Guo +2
We investigate the abundance, small-scale clustering and galaxy-galaxy lensing signal of galaxies in the Baryon Oscillation Spectroscopic Survey (BOSS). To this end, we present new…
DASH: a library of dynamical subhalo evolution
Go Ogiya, Frank C. van den Bosch, Oliver Hahn +3
The abundance and demographics of dark matter substructure is important for many areas in astrophysics and cosmological -body simulations have been the primary tool used to inve…
Constraining the mass density of free-floating black holes using razor-thin lensing arcs
Uddipan Banik, Frank C. van den Bosch, Michael Tremmel +5
Strong lensing of active galactic nuclei in the radio can result in razor-thin arcs, with a thickness of less than a milli-arcsecond, if observed at the resolution achievable with…
Cosmological simulations of the circumgalactic medium with 1 kpc resolution: enhanced HI column densities
Freeke van de Voort, Volker Springel, Nir Mandelker +2
The circumgalactic medium (CGM), i.e. the gaseous haloes around galaxies, is both the reservoir of gas that fuels galaxy growth and the repository of gas expelled by galactic winds…
