Lower central dark matter densities in nearby galaxies than predicted by simulations
Yu Lei, Ling Zhu, Meng Yang +9
Baryonic feedback in hydrodynamical simulations is typically invoked to alleviate the core--cusp problem in dwarf galaxies. Yet baryonic processes also induce adiabatic contraction…
Euclid Quick Data Release (Q1). The Strong Lensing Discovery Engine F -- Bright and low-redshift strong lenses
Euclid Collaboration, L. R. Ecker, M. Fabricius +346
We present 72 additional galaxy-galaxy strong lenses that complement the sample discovered in the Euclid Quick Release 1 data (63.1 deg^2) of the Strong Lens Discovery Engine (SLDE…
Gas distributions inside and around haloes in the alternative dark matter simulations AIDA-TNG
Chi Zhang, Enrico Garaldi, Giulia Despali +3
The nature of Dark Matter (DM) is one of the greatest mysteries of modern astrophysics. While the standard Cold DM (CDM) model successfully explains observations on most astrophysi…
Self-interacting dark matter in the center of a Local Group dwarf galaxy and its satellites
Thales A. Gutcke, Giulia Despali, Stephanie O'Neil +3
We present a detailed comparison of a Local Group dwarf galaxy analogue evolved in two cosmological models: the standard CDM and a self-interacting dark matter (SIDM) model with…
Accretion of satellites onto central galaxies in clusters: merger mass ratios and orbital parameters
Carlo Nipoti, Carlo Giocoli, Giulia Despali
We study the statistical properties of mergers between central and satellite galaxies in galaxy clusters in the redshift range , using a sample of dark-matter only cosmologi…
