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…

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…

A tight angular-momentum plane for disc galaxies

Pavel E. Mancera Piña, Lorenzo Posti, Gabriele Pezzulli +4

The relations between the specific angular momenta () and masses () of galaxies are often used as a benchmark in analytic models and hydrodynamical simulations as they are co…

Zero-metallicity hypernova uncovered by an ultra metal-poor star in the Sculptor dwarf spheroidal galaxy

Ása Skúladóttir, Stefania Salvadori, Anish M. Amarsi +9

Although true metal-free "Population III" stars have so-far escaped discovery, their nature, and that of their supernovae, is revealed in the chemical products left behind in the n…

A universal relation between the properties of supermassive black holes, galaxies, and dark matter halos

A. Marasco, G. Cresci, L. Posti +5

We study the relations between the mass of the central black hole (BH) , the dark matter halo mass , and the stellar-to-halo mass fraction $f_\star\propto M_…

Dynamical evidence for a morphology-dependent relation between the stellar and halo masses of galaxies

Lorenzo Posti, S. Michael Fall

We derive the stellar-to-halo mass relation (SHMR), namely versus and , for early-type galaxies from their near-IR luminosit…
