Shining a light on galactic outflows: photoionized outflows [PDF]
Monthly Notices of the Royal Astronomical Society, 2016 We study the ionization structure of galactic outflows in 37 nearby, star forming galaxies with the Cosmic Origins Spectrograph on the Hubble Space Telescope. We use the O I, Si II, Si III, and Si IV ultraviolet absorption lines to characterize the different ionization states of outflowing gas. We measure the equivalent widths, line widths, and outflow

Rotation of the outflow tracts [PDF]
Interactive CardioVascular and Thoracic Surgery, 2018 The optimal treatment for transposition of the great arteries with stenosis along the pulmonary tract has always been a challenge. En bloc rotation of the truncus arteriosus has been proposed as an alternative method in this group of patients. We report a truncus turnover in a 3-month-old, 3.4 kg infant.

PROTOSTELLAR OUTFLOWS IN L1340 [PDF]
The Astrophysical Journal, 2016 ABSTRACT We have searched the L1340 A, B, and C clouds for shocks from protostellar outflows using the H2 2.122 μm near-infrared line as a shock tracer. Substantial outflow activity has been found in each of the three regions of the cloud (L1340 A, L1340 B, and L1340 C).

The mass and momentum outflow rates of photoionized galactic outflows [PDF]
Monthly Notices of the Royal Astronomical Society, 2017 Galactic outflows are believed to play an important role in regulating star formation in galaxies, but estimates of the outflowing mass and momentum have historically been based on uncertain assumptions. Here, we measure the mass, momentum, and energy outflow rates of seven nearby star-forming galaxies using ultraviolet absorption lines and ...

THE CIRCUMBINARY OUTFLOW: A PROTOSTELLAR OUTFLOW DRIVEN BY A CIRCUMBINARY DISK [PDF]
The Astrophysical Journal, 2009 The protostellar outflows have indispensable role in the formation of single stars, because they carry off the excess angular momentum from the centre of the shrinking gas cloud, and permits further collapse to form a star. On the other hand, a significant fraction of stars is supposed to be born as binaries with circumbinary disk that are frequently ...

Outflow Propagation in Collapsars: Collimated Jets and Expanding Outflows [PDF]
Astrophysics and Space Science, 2006 We investigate the outflow propagation in the collapsar in the context of gamma-ray bursts (GRBs) with 2D relativistic hydrodynamic simulations. We vary the specific internal energy and bulk Lorentz factor of the injected out- flow from non-relativistic regime to relativistic one, fixing the power of the outflow to be 1051erg s−1.

Emergence of a quasar outflow [PDF]
Monthly Notices of the Royal Astronomical Society: Letters, 2008 Abstract We report the first discovery of the emergence of a high-velocity broad-line outflow in a luminous quasar, J105400.40+034801.2, at redshift z∼ 2.1. The outflow is evident in ultraviolet C iv and Si iv absorption lines with velocity shifts v∼ 26 300 km s−1 and deblended widths FWHM ∼4000 km s−1.
