Metals in Star-Forming Galaxies at High Redshift
The chemical composition of high-redshift galaxies is an important property that gives clues to their past history and future evolution. Measuring abundances in distant galaxies with current techniques is often a challenge, and the canonical metallicity indicators can often not be applied. I discuss currently available metallicity indicators based on stellar and interstellar absorption and emis...
متن کاملThe Rest-frame Submillimeter Spectrum of High-redshift, Dusty, Star-forming Galaxies
We present the average rest-frame spectrum of high-redshift dusty, star-forming galaxies from 250− 770GHz. This spectrum was constructed by stacking ALMA 3mm spectra of 22 such sources discovered by the South Pole Telescope and spanning z = 2.0 − 5.7. In addition to multiple bright spectral features of CO, [CI], and H2O, we also detect several faint transitions of CO, HCN, HNC, HCO, and CN, and...
متن کاملThe Star-Forming Molecular Gas in High-Redshift Submillimetre Galaxies
We present a model for the CO molecular line emission from high-redshift Submillimetre Galaxies (SMGs). By combining hydrodynamic simulations of gas-rich galaxy mergers with the polychromatic radiative transfer code, SUNRISE, and the 3D non-LTE molecular line radiative transfer code, TURTLEBEACH, we show that if SMGs are typically a transient phase of major mergers, then their observed compact ...
متن کاملThe Kiloparsec-scale Kinematics of High-redshift Star-forming Galaxies
We present the results of a spectroscopic survey of the kinematic structure of star-forming galaxies at redshift z ∼ 2 − 3 using Keck/OSIRIS integral field spectroscopy. Our sample is comprised of 12 galaxies between redshifts z ∼ 2.0 and 2.5 and one galaxy at z ∼ 3.3 which are well detected in either Hα or [O iii] emission. These galaxies are generally representative of the mean stellar mass o...
متن کاملRadio Observations of High Redshift Star Forming Galaxies
I summarize recent results from radio observations of high redshift star forming galaxies, discuss radio continuum emission as a measure of star formation rate, and consider future capabilities at cm to IR wavelengths. 1 Radio surveys to μJy sensitivity Source counts based on low frequency surveys of the sky with Jy sensitivity showed a significant departure from a Euclidean, non-evolving sourc...
