Most of the cool CGM of star-forming galaxies is not produced by supernova feedback
Andrea Afruni, Filippo Fraternali, Gabriele Pezzulli
The characterization of the large amount of gas residing in the galaxy halos, the so called circumgalactic medium (CGM), is crucial to understand galaxy evolution across cosmic tim…
Revealing the Impact of Quasar Luminosity on Giant Ly Nebulae
Ruari Mackenzie, Gabriele Pezzulli, Sebastiano Cantalupo +6
We present the results from a MUSE survey of twelve quasars, which were selected to be much fainter (20<i<23) than in previous studies of Giant Ly Nebulae around t…
The impact of the halo spin-concentration relation on disc scaling laws
Lorenzo Posti, Benoit Famaey, Gabriele Pezzulli +3
Galaxy scaling laws, such as the Tully-Fisher, mass-size and Fall relations, can provide extremely useful clues on our understanding of galaxy formation in a cosmological context.…
The volumetric star formation law for nearby galaxies -- Extension to dwarf galaxies and low-density regions
Cecilia Bacchini, Filippo Fraternali, Gabriele Pezzulli +1
In the last decades, much effort has been put into finding the star formation law which could unequivocally link the gas and the star formation rate (SFR) densities measured on sub…
The nature of CR7 revealed with MUSE: a young starburst powering extended Lyman- emission at z=6.6
Jorryt Matthee, Gabriele Pezzulli, Ruari Mackenzie +11
CR7 is among the most luminous Lyman- emitters (LAEs) known at and consists of at least three UV components that are surrounded by Lyman- (Ly) emission. Previous…
Evidence for supernova feedback sustaining gas turbulence in nearby star-forming galaxies
Cecilia Bacchini, Filippo Fraternali, Giuliano Iorio +3
It is well known that gas in galaxy discs is highly turbulent, but there is much debate on which mechanism can energetically maintain this turbulence. Among the possible candidates…
Probing the AGN Unification Model at redshift z 3 with MUSE observations of giant Ly nebulae
J. S. den Brok, S. Cantalupo, R. Mackenzie +7
A prediction of the classic active galactic nuclei (AGN) unification model is the presence of ionisation cones with different orientations depending on the AGN type. Confirmations…
Robust HI kinematics of gas-rich ultra-diffuse galaxies: hints of a weak-feedback formation scenario
Pavel E. Mancera Piña, Filippo Fraternali, Kyle A. Oman +15
We study the gas kinematics of a sample of six isolated gas-rich low surface brightness galaxies, of the class called ultra-diffuse galaxies (UDGs). These galaxies have recently be…
The MUSE Hubble Ultra Deep Field Survey XIII. Spatially resolved spectral properties of Lyman alpha haloes around star-forming galaxies at z > 3
Floriane Leclercq, Roland Bacon, Anne Verhamme +18
We present spatially resolved maps of six individually-detected Lyman alpha haloes (LAHs) as well as a first statistical analysis of the Lyman alpha (Lya) spectral signature in the…
