The growth of the central region by acquisition of counter-rotating gas in star-forming galaxies
Yan-Mei Chen, Yong Shi, Christy A. Tremonti +29
Galaxies grow through both internal and external processes. In about 10% of nearby red galaxies with little star formation, gas and stars are counter-rotating, demonstrating the im…
The Molecular Baryon Cycle of M82
John Chisholm, Satoki Matsushita
Baryons cycle into galaxies from the inter-galactic medium, are converted into stars, and a fraction of the baryons are ejected out of galaxies by stellar feedback. Here we present…
A Robust Measurement of the Mass Outflow Rate of the Galactic Outflow from NGC 6090
John Chisholm, Christy A. Tremonti, Claus Leitherer +1
To evaluate the impact of stellar feedback, it is critical to estimate the mass outflow rates of galaxies. Past estimates have been plagued by uncertain assumptions about the outfl…
Shining A Light On Galactic Outflows: Photo-Ionized Outflows
John Chisholm, Christy A. Tremonti, Claus Leitherer +2
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…
