Disk galaxies are self-similar: the universality of the HI-to-Halo mass ratio for isolated disks

Marie Korsaga, Benoit Famaey, Jonathan Freundlich +7

Observed scaling relations in galaxies between baryons and dark matter global properties are key to shed light on the process of galaxy formation and on the nature of dark matter.…

The fragility of thin discs in galaxies -- I. Building tailored N-body galaxy models

Pablo M. Galán-de Anta, Eugene Vasiliev, Marc Sarzi +6

Thin stellar discs on both galactic and nuclear, sub-kpc scales are believed to be fragile structures that would be easily destroyed in major mergers. In turn, this makes the age-d…

Rotation curve decompositions with Gaussian Processes: taking into account data correlations leads to unbiased results

Lorenzo Posti

Correlations between velocity measurements in disk galaxy rotation curves are usually neglected when fitting dynamical models. Here I show how data correlations can be taken into a…

Dark matter halos and scaling relations of extremely massive spiral galaxies from extended HI rotation curves

Enrico M. Di Teodoro, Lorenzo Posti, S. Michael Fall +6

We present new and archival atomic hydrogen (\hi) observations of \galnum\ of the most massive spiral galaxies in the local Universe (). From 3…

The phantom dark matter halos of the Local Volume in the context of modified Newtonian dynamics

P. -A. Oria, B. Famaey, G. F. Thomas +8

We explore the predictions of Milgromian gravity (MOND) in the Local Universe by considering the distribution of the `phantom' dark matter (PDM) that would source the MOND gravitat…

Rotation curves and scaling relations of extremely massive spiral galaxies

Enrico M. Di Teodoro, Lorenzo Posti, Patrick M. Ogle +2

We study the kinematics and scaling relations of a sample of 43 giant spiral galaxies that have stellar masses exceeding and optical discs up to 80 kpc in radiu…
