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…
The AIDA-TNG project. Abundance, radial distribution, and clustering properties of halos in alternative dark matter models
Massimiliano Romanello, Giulia Despali, Federico Marulli +3
Warm and self-interactive dark matter cosmologies have been proposed as nonbaryonic solutions to the tensions between the cold dark matter model and observations at the kilopa…
The AIDA-TNG project: gas distributions inside and around haloes
Chi Zhang, Enrico Garaldi, Giulia Despali +3
The nature of Dark Matter (DM) is one of the most outstanding mysteries of modern astrophysics. While the standard Cold DM (CDM) model successfully explains observations on most as…
The AIDA-TNG project: dark matter profiles and concentrations in alternative dark matter models
Giulia Despali, Carlo Giocoli, Lauro Moscardini +3
In the standard Cold Dark Matter (CDM) scenario, the density profiles of dark matter haloes are well described by analytical models linking their concentration to halo mass. Altern…
The AIDA-TNG project: 3D halo shapes
C. Giocoli, G. Despali, L. Moscardini +4
Context. The shapes of dark matter halos can be used to constrain the fundamental properties of dark matter. In standard Cold Dark Matter (CDM) cosmologies, halos are typically tri…
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 wit…
