The current knowledge on the stellar IMF is documented. It is usually described as being
invariant, but evidence to the contrary has emerged: it appears to become top-heavy when …

ABSTRACT X-ray photons, because of their long mean-free paths, can easily escape the
galactic environments where they are produced, and interact at long distances with the …

We present an analysis of the global and spatially resolved Kennicutt–Schmidt (KS) star
formation relation in the FIRE (Feedback In Realistic Environments) suite of cosmological …

Context. The observational study of star-formation relations in galaxies is central for
unraveling the related physical processes that are at work on local and global scales. It is …

We present observational evidence of a correlation between the high-mass slope of the
stellar initial mass function (IMF) in young star clusters and their stellar surface density, σ …

Context. Tracing the molecular gas-phase in low-mass star-forming galaxies becomes
extremely challenging due to significant UV photo-dissociation of CO molecules in their low …

We show that the bulge and the disk of the Milky Way (MW) at R≲ 7 kpc are well described
by a unique chemical evolution and a two-phase star formation history (SFH). We argue that …

We investigate several panchromatic scaling relations (SRs) for the dwarf irregular galaxy
NGC 1569 using Integral Field Unit (IFU) data from the Metal-THINGS Survey. Among the …

Observations of external galaxies and of local star-forming clouds in the Milky Way have
suggested a variety of star formation laws, ie simple direct relations between the column …

For investigating the relationship between the star formation rate and gas surface density,
we develop a Bayesian linear regression method that rigorously treats measurement …
