ELUCID-DESI II. Revealing dark matter mass, tidal, and velocity (MTV) fields using galaxy group phase information
Qingyang Li, Xiaohu Yang, Wensheng Hong +24
We introduce a novel method for reconstructing the cosmic mass, tidal, and velocity (MTV) fields over the redshift range using the phase information of galaxy groups.…
Identifying Galaxy Cluster Mergers with Deep Neural Networks using Idealized Compton-y and X-ray maps
Ashleigh R. Arendt, Yvette C. Perrott, Ana Contreras-Santos +3
We present a novel approach to identify galaxy clusters that are undergoing a merger using a deep learning approach. This paper uses massive galaxy clusters spanning $0 \leq z \leq…
ELUCID VIII: Simulating the Coma Galaxy Cluster to Calibrate Model and Understand Feedback
Xiong Luo, Huiyuan Wang, Weiguang Cui +9
We conducted an investigation of the Coma cluster of galaxies by running a series of constrained hydrodynamic simulations with GIZMO-SIMBA and GADGET-3, based on initial conditions…
The localization of galaxy groups in close proximity to galaxy clusters using cosmic web nodes
Daniel J. Cornwell, Ulrike Kuchner, Meghan E. Gray +4
We investigate the efficacy of using the cosmic web nodes identified by the DisPerSE topological filament finder to systematically identify galaxy groups in the infall regions arou…
A persistent excess of galaxy-galaxy strong lensing observed in galaxy clusters
Massimo Meneghetti, Weiguang Cui, Elena Rasia +18
Previous studies have revealed that the estimated probability of galaxy-galaxy strong lensing in observed galaxy clusters exceeds the expectations from the Cold Dark Matter cos…
The Three Hundred: relation
Atulit Srivastava, Weiguang Cui, Massimo Meneghetti +8
In this study, we investigate a recent finding based on strong lensing observations, which suggests that the sub-halos observed in clusters exhibit greater compactness compared to…
