AGN Feedback in SDSS-IV MaNGA: AGNs have Suppressed Central Star Formation Rates
Caleb Lammers, Kartheik G. Iyer, Hector Ibarra-Medel +4
Despite the importance of feedback from active galactic nuclei (AGNs) in models of galaxy evolution, observational constraints on the influence of AGN feedback on star formation re…
Galaxy mergers can rapidly shut down star formation
Sara L. Ellison, Scott Wilkinson, Joanna Woo +6
Galaxy mergers trigger both star formation and accretion onto the central supermassive black hole. As a result of subsequent energetic feedback processes, it has long been proposed…
The physical connection between central stellar surface density and stellar spin in SAMI and MaNGA nearby galaxies
L. Cortese, A. Fraser-McKelvie, J. Woo +8
The stellar surface density within the inner 1 kpc () has become a popular tool for understanding the growth of galaxies and its connection with the quenching of star format…
Quenching Timescales in the IllustrisTNG Simulation
Dan Walters, Joanna Woo, Sara L. Ellison
The timescales for galaxy quenching offer clues to its underlying physical drivers. We investigate central galaxy quenching timescales in the IllustrisTNG 100-1 simulation, their e…
Mapping the Diversity of Galaxy Spectra with Deep Unsupervised Machine Learning
Hossen Teimoorinia, Finn Archinuk, Joanna Woo +2
Modern spectroscopic surveys of galaxies such as MaNGA consist of millions of diverse spectra covering different regions of thousands of galaxies. We propose and implement a deep u…
Interacting galaxies in the IllustrisTNG simulations -- III: (the rarity of) quenching in post-merger galaxies
Salvatore Quai, Maan H. Hani, Sara L. Ellison +2
Galaxy mergers are traditionally one of the favoured mechanisms for quenching star formation. To test this paradigm in the context of modern cosmological simulations, we use the Il…
The Structural Evolution of Isolated Galaxies at Low Redshift in the IllustrisTNG Simulation
Dan Walters, Joanna Woo, Sara L. Ellison +1
We study the structural evolution of isolated star-forming galaxies in the Illustris TNG100-1 hydrodynamical simulation, with a focus on investigating the growth of the central cor…
Interacting galaxies in the IllustrisTNG simulations -- I: Triggered star formation in a cosmological context
David R. Patton, Kieran D. Wilson, Colin J. Metrow +7
We use the IllustrisTNG cosmological hydrodynamical simulations to investigate how the specific star formation rates (sSFRs) of massive galaxies depend on…
The Activation of Galactic Nuclei and Their Accretion Rates are Linked to the Star Formation Rates and Bulge-types of Their Host Galaxies
Hassen M. Yesuf, S. M. Faber, David C. Koo +3
We use bulge-type classifications of 809 representative SDSS galaxies by Gadotti (2009) to classify a large sample of galaxies into real bulges (classical or elliptical) and pseudo…
The MUSE Atlas of Disks (MAD): Ionized gas kinematic maps and an application to Diffuse Ionized Gas
Mark den Brok, C. Marcella Carollo, Santiago Erroz-Ferrer +9
We have obtained data for 41 star forming galaxies in the MUSE Atlas of Disks (MAD) survey with VLT/MUSE. These data allow us, at high resolution of a few 100 pc, to extract ionize…
Quenching as a Contest between Galaxy Halos and their Central Black Holes
Zhu Chen, S. M. Faber, David. C. Koo +27
Existing models of galaxy formation have not yet explained striking correlations between structure and star-formation activity in galaxies, notably the sloped and moving boundaries…
Structural and Stellar Population Properties vs. Bulge Types in Sloan Digital Sky Survey Central Galaxies
Yifei Luo, S. M. Faber, Aldo Rodriguez-Puebla +12
This paper studies pseudo-bulges (P-bulges) and classical bulges (C-bulges) in Sloan Digital Sky Survey central galaxies using the new bulge indicator , which measures relati…
What shapes a galaxy? - Unraveling the role of mass, environment and star formation in forming galactic structure
Asa F. L. Bluck, Connor Bottrell, Hossen Teimoorinia +9
We investigate the dependence of galaxy structure on a variety of galactic and environmental parameters for ~500,000 galaxies at z<0.2, taken from the Sloan Digital Sky Survey data…
The MUSE Atlas of Disks (MAD): Resolving Star Formation Rates and Gas Metallicities on < 100pc Scales
Santiago Erroz-Ferrer, C. Marcella Carollo, Mark den Brok +13
We study the physical properties of the ionized gas in local disks using the sample of 38 nearby M Star-Forming Main Sequence (SFMS) galaxies observed so…
Two Growing Modes and the Morphology-Quiescence Relation in Galaxies
Joanna Woo, Sara L. Ellison
Quiescence in galaxies correlates strongly with the central density/morphology of the stellar distribution. We investigate two possible explanations for this morphology-quiescence…

Sandro Tacchella, C. Marcella Carollo, S. M. Faber +5
We investigate the origin of the evolution of the population-averaged central stellar mass density () of quiescent galaxies (QGs) by probing the relation between stellar age a…
Supermassive black holes as the regulators of star formation in central galaxies
Bryan A. Terrazas, Eric F. Bell, Joanna Woo +1
We present a relationship between the black hole mass, stellar mass, and star formation rate of a diverse group of 91 galaxies with dynamically-measured black hole masses. For our…
Quiescence correlates strongly with directly-measured black hole mass in central galaxies
Bryan A. Terrazas, Eric F. Bell, Bruno M. B. Henriques +3
Roughly half of all stars reside in galaxies without significant ongoing star formation. However, galaxy formation models indicate that it is energetically challenging to suppress…
Satellite Quenching, Galaxy Inner Density and the Halo Environment
