Luciano Casarini - Visualizations

Light density distributions of three independent projections of an Late-Type Galaxy (upper row) and an Early-Type Galaxy (lower row), together with their structural parameters. The LTG is characterized by a low Sérsic index and a disky morphology, while the ETG has a higher Sérsic index and a smooth, spheroidal morphology.

The two panels illustrate the imprint of radiation driving on the CMB acoustic spectrum for an interacting dark energy model (left) and a Generalized Chaplygin Gas model (right). Varying the parameters of each model produces a qualitatively similar modification of the acoustic peak structure in both scenarios.

Projected density maps of our sample at z = 0. From top to bottom, we show different haloes with masses ranging from approximately 2×10^12 Msun to 6×10^11 Msun. From left to right, we show the ΛCDM and different coupled dark energy models. All projections have a radius of R200. Right: Density maps of a dwarf-galaxy halo with a mass of 4×10^9 Msun in the ΛCDM model (upper panel) and in one of the coupled dark energy models (lower panel). The side length of each projection is 2 × R200.

Zoomed hydrodynamical simulations of a disc galaxy in the SUCDM (top) and CPL (bottom) cosmologies. From left to right: the large-scale gas distribution, highlighting the surrounding cosmic web and filamentary structures feeding the galaxy; a close-up of the gas distribution in the central region; and a close-up of the corresponding stellar distribution.
