The Immitigable Nature of Assembly Bias: The Impact of Halo Definition on Assembly Bias [PDF]
MNRAS, 472, 1088-1105 (2017), 2017 Dark matter halo clustering depends not only on halo mass, but also on other properties such as concentration and shape. This phenomenon is known broadly as assembly bias.

How are galaxies assigned to halos? Searching for assembly bias in the SDSS galaxy clustering [PDF]
, 2018 Clustering of dark matter halos has been shown to depend on halo properties beyond mass such as halo concentration, a phenomenon referred to as halo assembly bias.

Evidence for an Intermediate-mass Milky Way from Gaia DR2 Halo Globular Cluster Motions [PDF]
Astrophysical Journal, 2018 We estimate the mass of the Milky Way (MW) within 21.1 kpc using the kinematics of halo globular clusters (GCs) determined by Gaia. The second Gaia data release (DR2) contained a catalog of absolute proper motions (PMs) for a set of Galactic GCs and ...

An Accurate Physical Model for Halo Concentrations [PDF]
Astrophysical Journal, 2018 The relation between halo mass, M, and concentration, c, is a critical component in our understanding of the structure of dark matter halos. While numerous models for this relation have been proposed, almost none of them attempt to derive the evolution ...

Magnetic field–induced pair density wave state in the cuprate vortex halo [PDF]
Science, 2018 Decoding the halo pattern Magnetic fields can cause the formation of vortices in a superconductor. In cuprate superconductors, the vortex cores are surrounded by “halos,” where the density of electronic states exhibits a checkerboard pattern.

Universe, 2021 In this paper, we further elaborate on the Bose–Einstein condensate (BEC) dark matter model extended in our previous work [Phys. Rev. D 2020, 102, 083510] by the inclusion of sixth-order (or three-particle) repulsive self-interaction term.

A physical and concise halo model based on the depletion radius [PDF]
, 2023 We develop a self-consistent and accurate halo model by partitioning matter according to the depletion radii of haloes. Unlike conventional models that define haloes with the virial radius while relying on a separate exclusion radius or ad-hoc fixes to account for halo exclusion, our model distributes mass across all scales self-consistently and ...
