Star-forming Dwarf Galaxies: Ariadne’s Thread in the Cosmic Labyrinth Stellar kinematics in blue compact galaxies
In a programme of observations of local luminous blue compact galaxies (BCGs) we are investigating kinematics by using tracers of both stars and ionised gas. Here we summarise our program and present new data on the local Lyman break galaxy analogue Haro 11. From spatially-resolved spectroscopy around the near-infrared Ca ii triplet, we find that its stars and ionised gas have similar velocity ...
متن کاملGas metallicity diagnostics in star-forming galaxies
Generally the gas metallicity in distant galaxies can only be inferred by using a few prominent emission lines. Various theoretical models have been used to predict the relationship between emission line fluxes and metallicity, suggesting that some line ratios can be used as diagnostics of the gas metallicity in galaxies. However, accurate empirical calibrations of these emission line flux rati...
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 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 ...
