Evidence for supernova feedback sustaining gas turbulence in nearby star-forming galaxies

C. Bacchini, F. Fraternali, G. Pezzulli +3

HI and CO observations indicate that the cold gas in galaxies is very turbulent. However, the turbulent energy is expected to be quickly dissipated, implying that some energy sourc…

The volumetric star formation law in nearby galaxies

C. Bacchini, F. Fraternali, G. Pezzulli +3

Star formation laws are empirical relations between the cold gas (HI+H) content of a galaxy and its star formation rate (SFR), being crucial for any model of galaxy formation a…

Compact object mergers: exploring uncertainties from stellar and binary evolution with SEVN

Giuliano Iorio, Michela Mapelli, Guglielmo Costa +9

Population-synthesis codes are an unique tool to explore the parameter space of massive binary star evolution and binary compact object (BCO) formation. Most population-synthesis c…

RR Lyrae From Binary Evolution: Abundant, Young and Metal-Rich

Alexey Bobrick, Giuliano Iorio, Vasily Belokurov +3

RR Lyrae are a well-known class of pulsating horizontal branch stars widely used as tracers of old, metal-poor stellar populations. However, mounting observational evidence shows t…

The impact of gas disc flaring on rotation curve decomposition and revisiting baryonic and dark-matter relations for nearby galaxies

Pavel E. Mancera Piña, Filippo Fraternali, Tom Oosterloo +4

Gas discs of late-type galaxies are flared, with scale heights increasing with the distance from the galaxy centres and often reaching kpc scales. We study the effects of gas disc…

Revisiting Common Envelope Evolution -- A New Semi-Analytic Model for N-body and Population Synthesis Codes

Alessandro Alberto Trani, Steven Rieder, Ataru Tanikawa +5

We present a novel way of modeling common envelope evolution in binary and few-body systems. We consider the common envelope inspiral as driven by a drag force with a power-law dep…

The Smallest Scale of Hierarchy Survey (SSH). II. Extended star formation and bar-like features in the dwarf galaxy NGC 3741: recent merger or ongoing gas accretion?

F. Annibali, C. Bacchini, G. Iorio +12

Using Large Binocular Telescope deep imaging data from the Smallest Scale of Hierarchy Survey (SSH) and archival Hubble Space Telescope data, we reveal the presence of two elongate…
