| Outline of Annual Research Achievements |
Our program has met our goals to understand star formation at high redshift including the evolution of the interstellar medium (Kashino et al. 2017) and their environments. Our second science question “Does star formation rate depend on environment?” has been addressed in a paper under review by D. Kashino entitled “The FMOS-COSMOS survey of star-forming galaxies at z~1.6. V: Properties of dark matter halos containing Halpha emitting galaxies” (arXiv:1703.08326) that measures the dark matter halo masses of high-z star-forming galaxies. Additional studies on the gas content of starbursts using ALMA are near completion with one paper submitted in 2016 (“Molecular gas properties of starbursts at z~ 1.6”; J. Silverman et al.) and another close to submission (“A quintessential merger-driven starburst at z=1.52”; J. Silverman et al.). Both demonstrate the role of galaxy mergers in generating rapid and more efficient star formation due to the interaction. Additional ALMA observations have been awarded in 2016 (PI J. Silverman). A final catalog of spectroscopic redshifts and emission-line strengths has been produced. This catalog along with 1D spectra will be made available to the public in 2017.
