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…
