The role of supercluster filaments in shaping galaxy clusters
Raúl Baier-Soto, Yara Jaffé, Alexis Finoguenov +44
In a hierarchical CDM Universe, cosmic filaments serve as the primary channels for matter accretion into galaxy clusters, influencing the shape of their dark matter halos. We in…
On the growth of supermassive black holes formed from the gravitational collapse of fermionic dark matter cores
C. R. Argüelles, K. Boshkayev, A. Krut +5
Observations support the idea that supermassive black holes (SMBHs) power the emission at the center of active galaxies. However, contrary to stellar-mass BHs, there is a poor unde…
Galaxy rotation curves and universal scaling relations: comparison between phenomenological and fermionic dark matter profiles
A. Krut, C. R. Argüelles, P. -H. Chavanis +2
Galaxies show different halo scaling relations such as the Radial Acceleration Relation, the Mass Discrepancy Acceleration Relation (MDAR) or the dark matter Surface Density Relati…
Galaxy Distributions as Fractal Systems
Sharon Teles, Amanda R. Lopes, Marcelo B. Ribeiro
This paper discusses if large scale galaxy distribution samples containing almost one million objects can be characterized as fractal systems. The analysis performed by Teles et al…
Carnegie Supernova Project: kinky -band light-curves of Type Ia supernovae
P. J. Pessi, E. Y. Hsiao, G. Folatelli +19
We present detailed investigation of a specific -band light-curve feature in Type Ia supernovae (SNe Ia) using the rapid cadence and high signal-to-noise ratio light-curves obta…
LCDM halo substructure properties revealed with high resolution and large volume cosmological simulations
Ángeles Moliné, Miguel A. Sánchez-Conde, Alejandra Aguirre-Santaella +8
We investigate the structural properties, distribution and abundance of LCDM dark matter subhaloes using the Phi-4096 and Uchuu suite of N-body cosmological simulations. Thanks to…
