I’m very excited to share the first results from a new branch of my research, looking at the gas contents of galaxies which appear to be actively quenching star formation!

We’ve looked at the molecular gas in a couple objects previously, at both low and high spatial resolution. Now, Manuel Aravena and I extend that work to a large sample of SPT sources, and we’re able to test a couple claims from the literature and look at how the molecular gas has evolved over the history of the universe.
Stellar Masses and Star Formation Rates of Lensed, Dusty, Star-forming Galaxies from the SPT Surv...
ADS: Ma, Gonzalez, Spilker et al. 2015 arXiv: Ma, Gonzalez, Spilker et al. 2015 One of the most fundamental parameters of a galaxy is its stellar mass. Unfortunately, it’s been very hard to measure these for the SPT dusty galaxies I’ve been studying – since they’re lensed by foreground galaxies, the light from the foreground galaxy can totally […]
ADS: Spilker et al. 2015 ArXiv: Spilker et al. 2015 Stars are born from giant clouds of gas made mostly of molecular hydrogen. One of the best ways to observe this gas indirectly is to use the carbon monoxide (CO) molecule. It’s even better if you can observe it at high resolution – this can tell you […]
ADS: Hezaveh et al. 2013b arXiv: Hezaveh et al. 2013b This paper, another part of the trio we published at the same time, describes the initial results of our ALMA Cycle 0 program to take one-minute snapshot images of a large number of SPT galaxies. While we were pretty sure the galaxies were lensed, we […]
