I will review recent advances in sub-galactic scale modelling of star formation, with a
particular emphasize on the interplay between star formation and stellar feedback and
how this impacts galaxy formation and evolution over cosmic time.

State-of-the-art instrumentation is currently revolutionizing our view on the gas-star
cycle in nearby galaxies by resolving individual star-forming clouds and their young
stellar population. I will highlight recent results from several concerted legacy-type
surveys targeting galaxies in the Local Group and Local Universe. This includes (a)
the structure of the atomic and molecular gas...

The Kennicutt-Schmidt law relating the surface densities of the star-formation rate
(SFR) and gas (atomic and molecular) is a widely-accepted star-formation law.
However, it is a disk-averaged law smoothing over local variations, and hence may not
provide an explanation for the local relationship between SFR and gas density at the
sub-galactic scale. To further probe this, various groups...

In the era of multi-wavelength surveys of the Milky Way, we are well-equipped to
observationally characterise the conditions necessary for star formation on parsec
size-scales. With this wealth of information, we can now not only ask the question of
what these conditions are, but also why they arise where they do. I employ the
Herschel Galactic Plane survey (Hi-GAL) to study the connection...

Over the past decade, there has been a move to better connect observations with
numerical simulations. In this work we focus on mimicking the CO emission for
simulated Giant Molecular Clouds (GMCs). We performed a set of smooth particle
hydrodynamics (SPH) simulations with time-dependent chemistry, in which environmental
conditions such as mass, density, size, metallicity and Interstellar...

Beyond the observed proportionality between surface densities of molecular gas and
star formation, the efficiency of star formation varies significantly with
environment. I will review the situations where the star formation is triggered by
dynamical processes, such as bars or spirals, tidal interactions, ram-pressure
due to AGN feedback or in groups and clusters.

Gravitational instabilities play a primary role in shaping the structure and powering the
star formation activity of disc galaxies. We review the effort made by theorists to
provide the astronomical community with reliable disc stability diagnostics. The most
well-known diagnostic is Toomre's Q parameter, but there are newer and more powerful
tools for detecting gravitational...

Knowing how efficiently stars are formed in galaxies is fundamental to understand the
evolution of our universe. Unfortunately, several physical processes governing star
formation are dynamically coupled in the non-linear regime, complicating the study of
their independent effects. Here we use numerical experiments to study the effects of
galactic rotation, employing the Adaptive Mesh...
