The impact of evolving cosmic filaments on mass and spin evolution of dark matter halos
Hannah Jhee, Hyunmi Song, Clotilde Laigle +3
The evolution of galaxies is closely tied to that of their host dark matter halos, which is in turn strongly modulated by the surrounding large-scale environment. Cosmic filaments…
Non-Gaussian Expansion of Minkowski Tensors in Redshift Space
Stephen Appleby, Christophe Pichon, Pravabati Chingangbam +2
This paper focuses on extending the use of Minkowski Tensors to analyze anisotropic signals in cosmological data, focusing on those introduced by redshift space distortion. We deri…
ODIN: Rest-frame Optical Morphologies and Star Formation Activity of Lyα Emitters at z=2.4, 3.1, and 4.5
Sang Hyeok Im, Ho Seong Hwang, Jeong Hwan Lee +19
We analyze the rest-frame optical (~8000 Å) morphologies and star formation activity of Lyα emitters (LAEs) at redshifts , , and , identified in the ODIN survey. To…
Which filaments matter: the relative scalings of anisotropic infall
Junsup Shim, Dmitri Pogosyan, Myoungwon Jeon +1
Dark-matter haloes do not form in isolation but within the surrounding cosmic web. By the time a halo begins to collapse, its larger-scale environment has typically collapsed along…
The Topology of Rayleigh-Levy Flights in Two Dimensions
Reginald Christian Bernardo, Stephen Appleby, Francis Bernardeau +1
Rayleigh-Lévy flights are simplified cosmological tools which capture certain essential statistical properties of the cosmic density field, including hierarchical structures in hi…
