Distribution and kinematics of atomic and molecular gas inside the Solar circle
A. Marasco, F. Fraternali, J. M. van der Hulst +1
The detailed distribution and kinematics of the atomic and the CO-bright molecular hydrogen in the disc of the Milky Way inside the Solar circle are derived under the assumptions o…
Massive disc galaxies in cosmological hydrodynamical simulations are too dark matter-dominated
A. Marasco, L. Posti, K. Oman +3
We investigate the disc-halo connection in massive (Mstar/Msun>5e10) disc galaxies from the cosmological hydrodynamical simulations EAGLE and IllustrisTNG, and compare it with that…
The first all-sky view of the Milky Way stellar halo with Gaia+2MASS RR Lyrae
G. Iorio, V. Belokurov, D. Erkal +3
We exploit the first \gaia data release to study the properties of the Galactic stellar halo as traced by RR Lyrae. We demonstrate that it is possible to select a pure sample of RR…
An optical and HI study of the dwarf Local Group galaxy VV124=UGC4879. A gas-poor dwarf with a stellar disk?
M. Bellazzini, G. Beccari, T. A. Oosterloo +8
We present a detailed study of the dwarf galaxy VV124, recently recognized as a isolated member of the Local Group. We have obtained deep (r=26.5) wide-field g,r photometry of indi…
Fountain-driven gas accretion by the Milky Way
F. Marinacci, F. Fraternali, J. Binney +3
Accretion of fresh gas at a rate of ~ 1 M_{sun} yr^{-1} is necessary in star-forming disc galaxies, such as the Milky Way, in order to sustain their star-formation rates. In this w…
The gaseous haloes of disc galaxies
F. Fraternali, T. Oosterloo, J. J. Binney +1
The study of gas outside the plane of disc galaxies is crucial to understanding the circulation of material within a galaxy and between galaxies and the intergalactic environment.…
