The Evolution of the Star-Forming Interstellar Medium Across Cosmic Time

Sternberg, Amiel; Genzel, Reinhard; Tacconi, Linda J.

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 ∼ 1-3) have become available. This rapid progress has been possible due to the advent of powerful ground- and space-based telescopes for the combined study of several mi…

Evidence for Initial Mass Function Variation in Massive Early-Type Galaxies

Smith, Russell J.

The initial mass function (IMF), describing the distribution of birth masses of stars, plays a pivotal role in establishing the observable properties of galaxies. This article reviews the evidence for variation in the IMF of massive early-type galaxies (ETGs), especially from spectroscopic studies and from dynamical and gravitational lensing measu…
