Shining a light on galactic outflows: photoionized outflows [PDF]

open access: yesMonthly 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.

The mass and momentum outflow rates of photoionized galactic outflows [PDF]

open access: yesMonthly 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.

Cooler and smoother – the impact of cosmic rays on the phase structure of galactic outflows [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2018
We investigate the impact of cosmic rays (CRs) on galactic outflows from a multi-phase interstellar medium with solar neighbourhood conditions. The three-dimensional magneto-hydrodynamical simulations include CRs as a relativistic fluid in the advection ...

The Role of Magnetic Fields in Protostellar Outflows and Star Formation [PDF]

open access: yesFrontiers in Astronomy and Space Sciences, 2019
The role of outflows in the formation of stars and the protostellar disks that generate them is a central question in astrophysics. Outflows are associated with star formation across the entire stellar mass spectrum.

Smoothed particle magnetohydrodynamic simulations of protostellar outflows with misaligned magnetic field and rotation axes [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2015
We have developed a modified form of the equations of smoothed particle magnetohydrodynamics which are stable in the presence of very steep density gradients.

Metallicity and Quasar Outflows [PDF]

open access: yesThe Astrophysical Journal, 2012
Correlations are investigated of the outflow strength of quasars, as measured by the blueshift and asymmetry index (BAI) of the CIV line (Wang et al. 2011), with intensities and ratios of broad emission lines, based on composite quasar spectra built from

Cool outflows in galaxies and their implications [PDF]

open access: yesThe Astronomy and Astrophysics Review, 2020
Neutral-atomic and molecular outflows are a common occurrence in galaxies, near and far. They operate over the full extent of their galaxy hosts, from the innermost regions of galactic nuclei to the outermost reaches of galaxy halos.

Protostellar Outflows

open access: yesHighlights in Science Engineering and Technology, 2023
The formation of massive stars differs from low-mass stars due to their rapid evolution, relatively low abundance, and their burial within molecular clouds, making observations more challenging.

First Results from SMAUG: Characterization of Multiphase Galactic Outflows from a Suite of Local Star-forming Galactic Disk Simulations [PDF]

open access: yesAstrophysical Journal, 2020
Large-scale outflows in star-forming galaxies are observed to be ubiquitous and are a key aspect of theoretical modeling of galactic evolution, the focus of the Simulating Multiscale Astrophysics to Understand Galaxies (SMAUG) project. Gas blown out from

Ionized outflows from active galactic nuclei as the essential elements of feedback [PDF]

open access: yes, 2020
Outflows from active galactic nuclei (AGNs) are one of the fundamental mechanisms by which the central supermassive black hole interacts with its host galaxy. Detected in ≥50% of nearby AGNs, these outflows have been found to carry kinetic energy that is
