Massive star formation and feedback in W49A: The source of our Galaxy's most luminous water maser outflow

, 2009
We present high spatial resolution mid-IR images of the ring of UCHII regions in W49A obtained at Gemini North, allowing us to identify the driving source of its powerful H2O maser outflow.

MEF2C regulates outflow tract alignment and transcriptional control of Tdgf1 [PDF]

, 2016
Congenital heart defects are the most common birth defects in humans, and those that affect the proper alignment of the outflow tracts and septation of the ventricles are a highly significant cause of morbidity and mortality in infants.

Direct Imaging of a Compact Molecular Outflow from a Very Low-luminosity Object; L1521F-IRS

, 2013
We report interferometric observations of the VeLLO L1521F-IRS, in 12CO (2-1) line emission and the 1.3 mm continuum emission, using the Submillimeter Array (SMA).

Feedback and Outflows [PDF]

Proceedings of the International Astronomical Union, 2012
AbstractThe low stellar and gas mass fractions, low galaxy-wide star formation rates (relative to galactic dynamical times) and observations of rapid outflows from galaxies, all suggest that stars and active galactic nuclei violently alter the state of the interstellar and even inter-halo gas in galaxies. I argue that the low galaxy wide star formation

A fast and long-lived outflow from the supermassive black hole in NGC 5548 [PDF]

Science, 2014
Gas jets block extragalactic x-rays Supermassive black holes at the heart of active galaxies produce powerful gas outflows. NGC 5548 is one such source known to sustain a persistent outflow of ionized gas.

IC5063: AGN driven outflow of warm and cold gas [PDF]

, 2007
We present new ATCA 17- and 24-GHz radio images and ESO-NTT optical spectra of the radio-loud Seyfert galaxy IC5063, the first galaxy in which a fast (~ 600 km/s) outflow of neutral hydrogen was discovered.

The dependence of Galactic outflows on the properties and orientation of zCOSMOS galaxies at z ~ 1

, 2013
We present an analysis of cool outflowing gas around galaxies, traced by MgII absorption lines in the co-added spectra of a sample of 486 zCOSMOS galaxies at 1 < z < 1.5. These galaxies span a range of stellar masses (9.45< log[M*/Msun] 5-7 Msun/yr and a

Molecular line emission in NGC 1068 imaged with ALMA: I. An AGN-driven outflow in the dense molecular gas [PDF]

, 2014
Aims. We investigate the fueling and the feedback of star formation and nuclear activity in NGC 1068, a nearby (D = 14 Mpc) Seyfert 2 barred galaxy, by analyzing the distribution and kinematics of the molecular gas in the disk.

Rotating molecular outflows: the young T Tauri star in CB26

, 2008
The disk-outflow connection is thought to play a key role in extracting excess angular momentum from a forming proto-star. Though jet rotation has been observed in a few objects, no rotation of molecular outflows has been unambiguously reported so far ...

Development and Morphology of the Ventricular Outflow Tracts

World journal for pediatric & congenital heart surgery, 2016
It is customary, at the current time, to consider many, if not most, of the lesions involving the ventricular outflow tract in terms of conotruncal malformations.
