We review progress over the past decade in observations of large-scale star formation, with
a focus on the interface between extragalactic and Galactic studies. Methods of measuring …

Radiation, winds, and jets from the active nucleus of a massive galaxy can interact with its
interstellar medium, and this can lead to ejection or heating of the gas. This terminates star …

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 …

Supermassive black holes (BHs) have been found in 85 galaxies by dynamical modeling of
spatially resolved kinematics. The Hubble Space Telescope revolutionized BH research by …

Over the past decade, increasingly robust estimates of the dense molecular gas content in
galaxy populations between redshift z= 0 and the peak of cosmic galaxy/star formation (z∼ …

This paper provides an update of our previous scaling relations between galaxy-integrated
molecular gas masses, stellar masses, and star formation rates (SFRs), in the framework of …

Over the past decade, observations of the cool interstellar medium (ISM) in distant galaxies
via molecular and atomic fine structure line (FSL) emission have gone from a curious look …

Far-infrared and submillimeter wavelength surveys have now established the important role
of dusty, star-forming galaxies (DSFGs) in the assembly of stellar mass and the evolution of …

Massive galaxies in the young Universe, ten billion years ago, formed stars at surprising
intensities,. Although this is commonly attributed to violent mergers, the properties of many of …

Ever deeper and wider look-back surveys have led to a fairly robust outline of the cosmic
star-formation history, which culminated around; this period is often nicknamed “cosmic …
