The Radial Acceleration Relation in Galaxies and Clusters from a Two-Component, Virial-Motivated Framework
Christine C. Dantas, Andre L. B. Ribeiro, Hugo V. Capelato
We present a comparative analysis of acceleration data for gravitational systems drawn from multiple observational sources, including: (i) early-type galaxies (ETGs) (Lelli et al.…
The Kormendy relation of cluster galaxies in PPS regions
André L. B. Ribeiro, Paulo A. A. Lopes, Dailer F. Morell +4
We study a sample of 936 early-type galaxies located in 48 low-z regular galaxy clusters with at . We examine variations in the Kormendy rela…
Late growth of early-type galaxies in low-z massive clusters
A. L. B. Ribeiro, R. S. Nascimento, D. F. Morell +3
We study a sample of 936 early-type galaxies (ETGs) located in 48 low-z regular galaxy clusters with at . We examine variations in the concen…
Counts-in-Cells of subhaloes in the IllustrisTNG simulations: the role of baryonic physics
Christine C. Dantas
We present an analysis of the Counts-in-Cells (CiC) statistics of subhaloes in the publicly available IllustrisTNG cosmological simulations (TNG100-1, TNG100-3 and TNG300-3), consi…
The two-component virial theorem and the acceleration-discrepancy relation
Christine C. Dantas, Andre L. B. Ribeiro, Hugo V. Capelato
We revisit the "two-component virial theorem" (2VT) in the light of recent theoretical and observational results related to the "dark matter"(DM) problem. This modification of the…
