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

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

Cool outflows in galaxies and their implications [PDF]
The 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.

Highlights 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]
Astrophysical 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]
, 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

First results from the TNG50 simulation: galactic outflows driven by supernovae and black hole feedback [PDF]
Monthly notices of the Royal Astronomical Society, 2019 We present the new TNG50 cosmological, magnetohydrodynamical simulation – the third and final volume of the IllustrisTNG project. This simulation occupies a unique combination of large volume and high resolution, with a 50 Mpc box sampled by 21603 gas ...

Ionized outflows in local luminous AGN: what are the real densities and outflow rates? [PDF]
Monthly notices of the Royal Astronomical Society, 2020 We report on the determination of electron densities, and their impact on the outflow masses and rates, measured in the central few hundred parsecs of 11 local luminous active galaxies.

AGN outflows and feedback twenty years on [PDF]
Nature Astronomy, 2018 It is twenty years since the seminal works by Magorrian and co-authors and by Silk and Rees, which, along with other related work, ignited an explosion of publications connecting active galactic nucleus (AGN)-driven outflows to galaxy evolution.

Cold Molecular Outflows in the Local Universe and Their Feedback Effect on Galaxies [PDF]
Monthly notices of the Royal Astronomical Society, 2018 We study molecular outflows in a sample of 45 local galaxies, both star forming and AGN, primarily by using CO data from the ALMA archive and from the literature.
