The origin of the high-velocity cloud complex C
F. Fraternali, A. Marasco, L. Armillotta +1
High-velocity clouds consist of cold gas that appears to be raining down from the halo to the disc of the Milky Way. Over the past fifty years, two competing scenarios have attribu…
The WSRT HALOGAS Survey
George Heald, the HALOGAS Team
We present an overview of the HALOGAS (Hydrogen Accretion in LOcal GAlaxieS) Survey, which is the deepest systematic investigation of cold gas accretion in nearby spiral galaxies t…
The triggering of starbursts in low-mass galaxies
Federico Lelli, Marc Verheijen, Filippo Fraternali
Strong bursts of star formation in galaxies may be triggered either by internal or external mechanisms. We study the distribution and kinematics of the HI gas in the outer regions…
The extended structure of the dwarf irregular galaxy Sagittarius
G. Beccari, M. Bellazzini, F. Fraternali +6
We present a detailed study of the stellar and HI structure of the dwarf irregular galaxy Sagittarius. We use new deep and wide field photometry to trace the surface brightness pro…
A low HI column density filament in NGC 2403: signature of interaction or accretion
W. J. G. de Blok, Katie M. Keating, D. J. Pisano +6
Observed HI accretion around nearby galaxies can only account for a fraction of the gas supply needed to sustain the currently observed star formation rates. It is possible that ad…
Gas accretion from minor mergers in local spiral galaxies
Enrico Di Teodoro, Filippo Fraternali
In this paper we quantify the gas accretion rate from minor mergers onto star-forming galaxies in the Local Universe using HI observations of 148 nearby spiral galaxies (WHISP samp…
