Resolved spectroscopy of gravitationally lensed galaxies: recovering coherent velocity fields in subluminous z 23 galaxies
We present spatially resolved dynamics for six strongly lensed star-forming galaxies at z = 1.7–3.1, each enlarged by a linear magnification factor of ∼×8. Using the Keck laser guide star AO system and the OH-Suppressing Infra-Red Imaging Spectrograph integral field unit spectrograph, we resolve kinematic and morphological detail in our sample with an unprecedented fidelity, in some cases achie...
متن کاملA survey of the cold molecular gas in gravitationally lensed star - forming galaxies at z > 2
Using the Australia Telescope Compact Array (ATCA), we conducted a survey of CO J = 1− 0 and J = 2− 1 line emission towards strongly lensed high-redshift dusty star forming galaxies (DSFGs) previously discovered with the South Pole Telescope (SPT). Our sample comprises 17 sources that had CO-based spectroscopic redshifts obtained with the Atacama Large Millimeter/submillimeter Array (ALMA) and ...
متن کاملThe properties of galaxies at z > 5
In a recent paper Lehnert & Bremer have photometrically selected a sample of galaxies at z > 4.8 from a single VLT/FORS2 pointing and spectroscopically confirmed half of them to be at 4.8 < z < 5.8. To study the properties of such galaxies further, we have photometrically selected a similar sample (V AB > 28, i AB < 26.3, i AB − z AB > 0) from the HST ACS images of the Chandra Deep Field South....
متن کاملThe Baryonic and Dark Matter Properties of High Redshift Gravitationally Lensed Disk Galaxies
We present a detailed study of the structural properties of four gravitationally lensed disk galaxies at z = 1. Modelling the rotation curves on sub-kpc scales we derive the values for the disk mass, the reference dark matter density and core radius, and the angular momentum per unit mass. The derived models suggest that the rotation curve profile and amplitude are best fit with a dark matter c...
متن کاملHigh–Redshift Gravitationally Lensed Galaxies and Tunable Filter Imaging
Most surveys for multiply–imaged gravitational lenses, outside of rich galaxy clusters, are based on sifting through large samples of distant sources to identify the rare examples of lensing. An alternative strategy, based on the selection of optimal lines–of–sight, offers a number of significant advantages. Utilising the multiplex capability of wide–area multifibre spectroscopy, together with ...
