A weak gravitational lensing recalibration of the scaling relations linking the gas properties of dark halos to their mass
Wenting Wang, Simon White, Rachel Mandelbaum +3
We use weak gravitational lensing to measure mean mass profiles around Locally Brightest Galaxies (LBGs). These are selected from the SDSS/DR7 spectroscopic and photometric catalog…
A unified model for the spatial and mass distribution of subhaloes
Jiaxin Han, Shaun Cole, Carlos S. Frenk +1
N-body simulations suggest that the substructures that survive inside dark matter haloes follow universal distributions in mass and radial number density. We demonstrate that a sim…
The orbital PDF: the dynamical state of Milky Way sized haloes and the intrinsic uncertainty in the determination of their masses
Jiaxin Han, Wenting Wang, Shaun Cole +1
Using realistic cosmological simulations of Milky Way sized haloes, we study their dynamical state and the accuracy of inferring their mass profiles with steady-state models of dyn…
The orbital PDF: general inference of the gravitational potential from steady-state tracers
Jiaxin Han, Wenting Wang, Shaun Cole +1
We develop two general methods to infer the gravitational potential of a system using steady-state tracers, i.e., tracers with a time-independent phase-space distribution. Combined…
Major Mergers Going Notts: Challenges for Modern Halo Finders
Peter Behroozi, Alexander Knebe, Frazer R. Pearce +7
Merging haloes with similar masses (i.e., major mergers) pose significant challenges for halo finders. We compare five halo finding algorithms' (AHF, HBT, Rockstar, SubFind, and VE…
Planes of satellite galaxies: when exceptions are the rule
Marius Cautun, Sownak Bose, Carlos S. Frenk +5
The detection of planar structures within the satellite systems of both the Milky Way (MW) and Andromeda (M31) has been reported as being in stark contradiction to the predictions…
