The volumetric star formation law in the Milky Way
C. Bacchini, F. Fraternali, G. Pezzulli +3
Several open questions on galaxy formation and evolution have their roots in the lack of a universal star formation law, that could univocally link the gas properties, e.g. its den…
Young stars raining through the Galactic Halo: the nature and orbit of Price-Whelan 1
M. Bellazzini, R. A. Ibata, N. Martin +3
We present radial velocities for five member stars of the recently discovered young (age= 100-150 Myr) stellar system Price-Whelan 1 (PW 1), that is located far away in the Galacti…
HALOGAS: the properties of extraplanar HI in disc galaxies
A. Marasco, F. Fraternali, G. Heald +9
We present a systematic study of the extraplanar gas (EPG) in a sample of 15 nearby late-type galaxies at intermediate inclinations using publicly available, deep interferometric H…
Off the baryonic Tully-Fisher relation: a population of baryon-dominated ultra-diffuse galaxies
Pavel E. Mancera Piña, Filippo Fraternali, Elizabeth A. K. Adams +17
We study the gas kinematics traced by the 21-cm emission of a sample of six HIrich low surface brightness galaxies classified as ultra-diffuse galaxies (UDGs). Using the 3D kine…
Galaxy disc scaling relations: A tight linear galaxy -- halo connection challenges abundance matching
Lorenzo Posti, Antonino Marasco, Filippo Fraternali +1
In CDM cosmology, to first order, galaxies form out of the cooling of baryons within the virial radius of their dark matter halo. The fractions of mass and angular momentum reta…
