Radiation-pressure Waves and Multiphase Quasar Outflows [PDF]
, 2019 We report on quasar outflow properties revealed by analyzing more than 60 composite outflow spectra built from $\sim 60\,000$ CIV absorption troughs in the SDSS-III/BOSS DR12QBAL catalog. We assess the dependences of the equivalent widths of many outflow

International Astronomical Union Colloquium, 1989 The development of millimeter and submillimeter spectroscopy has allowed astronomers to probe the cold, dense component of the interstellar medium. This medium, primarily composed of gas in molecular form, is gravitationally bound into relatively distinct clouds that are sites of star formation within our Galaxy.

Resolved images of a protostellar outflow driven by an extended disk wind [PDF]
Nature, 2016 Young stars are associated with prominent outflows of molecular gas. The ejection of gas is believed to remove angular momentum from the protostellar system, permitting young stars to grow by the accretion of material from the protostellar disk.

Pharmacological regulation of outflow resistance distal to Schlemm's canal.
American Journal of Physiology - Cell Physiology, 2018 The trabecular meshwork (TM) and Schlemm's canal generate the majority of outflow resistance; however, the distal regions of the conventional outflow pathway account for 25-50% of total resistance.

Dense Molecular Gas Tracers in the Outflow of the Starburst Galaxy NGC 253 [PDF]
, 2017 We present a detailed study of a molecular outflow feature in the nearby starburst galaxy NGC 253 using ALMA. We find that this feature is clearly associated with the edge of NGC 253's prominent ionized outflow, has a projected length of ∼300 pc, with a ...

Rotational Structure and Outflow in the Infrared Dark Cloud 18223-3 [PDF]
, 2009 We examine an Infrared Dark Cloud (IRDC) at high spatial resolution as a means to study rotation, outflow, and infall at the onset of massive star formation.

Outflow forces of low mass embedded objects in Ophiuchus: a quantitative comparison of analysis methods [PDF]
, 2013 The outflow force of molecular bipolar outflows is a key parameter in theories of young stellar feedback on their surroundings. The focus of many outflow studies is the correlation between the outflow force, bolometric luminosity and envelope mass ...

The multi-phase winds of Markarian 231: from the hot, nuclear, ultra-fast wind to the galaxy-scale, molecular outflow [PDF]
, 2015 Mrk 231 is a nearby ultra-luminous IR galaxy exhibiting a kpc-scale, multi-phase AGN-driven outflow. This galaxy represents the best target to investigate in detail the morphology and energetics of powerful outflows, as well as their still poorly ...
