The MaNGA survey has revealed a new class of galaxies called “red geysers” that harbor supermassive black holes with winds that have the power to keep dormant galaxies quiet. You can read the Nature discovery paper by Edmond Cheung, myself, and the MaNGA team or check out press coverage from the PBS Newshour, the UK's Daily Mail, and Japan's Asahi Shinbun (朝日新聞).
resolving the physics of galaxy formation
I am the founder and Principal Investigator of MaNGA, one of three programs in the 4th Sloan Digital Sky Survey (SDSS-IV). MaNGA stands for Mappiang Nearby Galaxies at Apache Point Observatory and in Aug 2020 reached its goal of resolved spectroscopy for an unprecedented 10,000 galaxies. MaNGA has produced over 200 papers (as of 2020) on the life history of galaxies, providing clues about their early formation, maps of their ongoing growth, and insight into the processes that eventually cause their star formation to "die out." We have over 300 team members spanning more than 60 institutions around the world.
a new era of High-precision with large-volume surveys
Dark energy surveys are ushering in a new era of high-precision galaxy evolution where evolving populations can be tracked with vanishing statistical uncertainties. I am developing the observational and interpretative framework needed to exploit these large-volume data sets to answer questions like, how do galaxies grow? Do they assemble hierarchically like their dark matter halos? What drives transformations between evolving populations?
The Stripe 82 Massive Galaxy Catalog
Synthetic Aperture Matched Photometry
The S82MGC is a uniformly processed set of data products comprising the largest-volume mass-complete sample of galaxies beyond z > 0.1 constructed to date (Bundy et al. 2015b).
SuMIRe: Subaru's Hyper Surpime Cam and Prime Focus Spectrograph
The 300-night Hyper Suprime Cam (HSC, pictured) survey is underway at the Subaru Telescope ahead of the 2400-fiber Prime Focus Spectrograph planned for 2019. HSC-Wide will span 1400 deg2 to 26th magnitude in grizY bands, opening enormous volumes to galaxy evolution work at z < 2.
I am an Assistant Professor in the UCSC Department of Astronomy & Astrophysics. As an observational astronomer, I specialize in mapping the distribution, properties, and internal structure of galaxies across large cosmic volumes in order to address key questions about their formation and assembly history. My work combines statistical analyses of "Big Data" survey programs with targeted observations from premier facilities, especially Keck Observatory. I am particularly interested in the mechanisms that shut down star formation in galaxies and regulate their growth and assembly. I am the Principal Investigator of the Keck-FOBOS instrument project, and I lead an initiative at UCSC to develop the field of "Astrophotonics." We are building new tools that will dramatically enhance the capabilities of future instruments.
