Fast rotations in galaxies at cosmic noon indicate central concentration of stars, dark matter or massive black holes

Fernanda Roman-Oliveira, Francesca Rizzo, Filippo Fraternali

The rotation curves of regularly rotating disc galaxies are a unique probe of the gravitational potential and dark matter distribution. Until recently, matter decomposition of rota…

The ALMA-ALPAKA survey II. Evolution of turbulence in galaxy disks across cosmic time: difference between cold and warm gas

F. Rizzo, C. Bacchini, M. Kohandel +8

The gas in the interstellar medium (ISM) of galaxies is supersonically turbulent. Measurements of turbulence typically rely on cold gas emission lines for low-z galaxies and warm i…

A 3D view on the local gravitational instability of cold gas discs in star-forming galaxies at

C. Bacchini, C. Nipoti, G. Iorio +6

Local gravitational instability (LGI) is considered crucial for regulating star formation and gas turbulence in galaxy discs, especially at high redshift. Instability criteria usua…

Dynamical modelling and origin of gas turbulence in z 4.5 galaxies

Fernanda Roman-Oliveira, Francesca Rizzo, Filippo Fraternali

In recent years, a growing number of regularly rotating galaxy discs have been found at z 4. Such systems provide us with the unique opportunity to study the properties of d…

The ALMA-ALPAKA survey I: high-resolution CO and [CI] kinematics of star-forming galaxies at z = 0.5-3.5

F. Rizzo, F. Roman-Oliveira, F. Fraternali +13

Spatially-resolved studies of the kinematics of galaxies provide crucial insights into their assembly and evolution, enabling to infer the properties of the dark matter halos, deri…

Regular rotation and low turbulence in a diverse sample of z ~ 4.5 galaxies observed with ALMA

Fernanda Roman-Oliveira, Filippo Fraternali, Francesca Rizzo

The discovery of galaxies with regularly rotating discs at redshifts has been a puzzling challenge to galaxy formation models that tend to predict chaotic gas kinematics in…
