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…
