CO line emission represents the most accessible and widely used tracer of the molecular
ISM. This renders the translation of observed CO intensity into total H2 gas mass critical to …

We review current understanding of star formation, outlining an overall theoretical framework
and the observations that motivate it. A conception of star formation has emerged in which …

We investigate the momentum and energy budget of stellar feedback during different stages
of stellar evolution, and study its impact on the interstellar medium (ISM) using simulations of …

The mass of molecular gas in an interstellar cloud is often measured using line emission
from low rotational levels of CO, which are sensitive to the CO mass, and then scaling to the …

▪ Abstract Turbulence affects the structure and motions of nearly all temperature and density
regimes in the interstellar gas. This two-part review summarizes the observations, theory …

The morphology and kinematics of molecular clouds (MCs) are best explained as the
consequence of supersonic turbulence. Supersonic turbulence fragments MCs into dense …

We use three-dimensional (3D) numerical magnetohydrodynamic simulations to follow the
evolution of cold, turbulent, gaseous systems with parameters chosen to represent …

Dusty star-forming galaxies at high redshift (1< z< 3) represent the most intense star-forming
regions in the universe. Key aspects to these processes are the gas heating and cooling …

We propose that the stellar initial mass function (IMF) is universal in the sense that its
functional form arises as a consequence of the statistics of random supersonic flows. A …

We present the results of 3D relativistic hydrodynamic simulations of interaction of active
galactic nucleus jets with a dense turbulent two-phase interstellar medium, which would be …
