Correlation of Black Hole and Bulge Masses: Driven by Energy but Correlated with Momentum

open access: yes, 2010
We use a recent sample of 49 galaxies to show that there is a proportionality relation between the black hole mass M_BH and the quantity \mu =M_G*\sigma /c, where M_G is mass of the spheroidal stellar component and \sigma is the stellar velocity ...

A Review of the Theory of Galactic Winds Driven by Stellar Feedback [PDF]

open access: yesGalaxies, 2018
Galactic winds from star-forming galaxies are crucial to the process of galaxy formation and evolution, regulating star formation, shaping the stellar mass function and the mass-metallicity relation, and enriching the intergalactic medium with metals.

Playing with FIRE: A Galactic Feedback-halting Experiment Challenges Star Formation Rate Theories

open access: yesThe Astrophysical Journal
Stellar feedback influences the star formation rate (SFR) and the interstellar medium of galaxies in ways that are difficult to quantify numerically, because feedback is an essential ingredient of realistic simulations.

SUSTAINING GALAXY EVOLUTION: THE ROLE OF STELLAR FEEDBACK

open access: yesPublications of The Korean Astronomical Society, 2015
We have conducted a near-infrared monitoring campaign at the UK InfraRed Telescope (UKIRT), of the Local Group galaxy M33. The main aim was to identify stars in the very final stage of their evolution, and for which the luminosity is more directly related to the birth mass than the more numerous less-evolved giant stars that continue to increase in ...

The Average Stellar Population Age and Metallicity of Intermediate-redshift Quiescent Galaxies

open access: yesThe Astrophysical Journal
The HectoMAP spectroscopic survey provides a unique mass-limited sample of more than 35,000 quiescent galaxies ( D _n 4000 > 1.5) covering the redshift range 0.2  10 ^11 M _⊙ ) assemble the bulk of their stars at earlier epochs.
