J-PAS & FLAMINGO: Cosmic voids and void galaxies in the gravitational landscape of photometric surveys
J. A. Mansour, B. McCarthy, L. J. Liivamägi +34
The paper presents a method that uses a quasi‑gravitational potential field to identify dynamically dominant cosmic voids and their galaxies in photometric surveys like J‑PAS, show…
Exploring the CMB in Anisotropic Universes
Robbert W. Scholtens, Marcello Seri, Holger Waalkens +1
In recent years, there have been increasing challenges to the cosmological principle, based on new observations of e.g. supernovae and the cosmic bulk flow. As a result, the cosmol…
Caustic Skeleton and the Local Cosmic Web: the Coma Cluster node and the Pisces-Perseus ridge
Amelie Read, Job Feldbrugge, Celine Boehm +2
We apply caustic skeleton theory to the Manticore-Local simulations, which are Bayesian constrained reconstructions of the Local Universe from the 2M++ galaxy catalogue, and extrac…
Fundamental Cosmic Anisotropy and its Ramifications II: Perturbations in Bianchi spacetimes, and fixed in the Newtonian gauge
Robbert W. Scholtens, Marcello Seri, Holger Waalkens +1
The standard cosmological model is challenged by an ever-growing collection of observations, which invites (and stimulates) inquiry into possible additions and/or alterations. One…
Galaxy Populations in the IllustrisTNG Caustic Skeleton
Benjamin Hertzsch, Job Feldbrugge, Rien van de Weygaert
The caustic skeleton is a parameter-free and mathematically rigorous formalism for tracing the hierarchical formation history of the multiscale cosmic web from the singularities in…
Chemodynamic evidence of pristine gas accretion in the void galaxy VGS 12
Evgeniya Egorova, Kathryn Kreckel, Oleg Egorov +5
Accretion of metal-poor gas is expected to be an important channel of gas replenishment in galaxy evolution studies. However, observational evidence of this process is still relati…
