Dynamical Characterization of Galaxies at z~4-6 via Tilted Ring Fitting to ALMA [CII] Observations
G. C. Jones, C. L. Carilli, Y. Shao +7
Until recently, determining the rotational properties of galaxies in the early universe (z>4, Universe age <1.5Gyr) was impractical, with the exception of a few strongly lensed sys…
Are high redshift Galaxies hot? - Temperature of z > 5 Galaxies and Implications on their Dust Properties
Andreas L. Faisst, Peter L. Capak, Lin Yan +6
Recent studies have found a significant evolution and scatter in the IRX- relation at z > 4, suggesting different dust properties of these galaxies. The total far-infrared (FIR)…
Dust Properties of [CII] Detected z 5.5 Galaxies: New HST/WFC3 Near-IR Observations
Ivana Barišić, Andreas L. Faisst, Peter L. Capak +7
We examine the rest-frame ultra-violet (UV) properties of 10 [CII]detected galaxies at in COSMOS using new HST/WFC3 near-infrared imaging. Toget…
High dense gas fraction in a gas-rich star-forming galaxy at z = 1.2
Avani Gowardhan, Dominik A. Riechers, Emanuele Daddi +3
We report observations of dense molecular gas in the star-forming galaxy EGS 13004291 (z=1.197) using the Plateau de Bure Interferometer. We tentatively detect HCN and HNC (J=2-1)…
Molecular Gas Kinematics and Star Formation Properties of the Strongly-Lensed Quasar Host Galaxy RXS J1131-1231
T. K. Daisy Leung, Dominik A. Riechers, Riccardo Pavesi
We report observations of CO(J=2-1) and CO(J=3-2) line emission towards the quadruply-lensed quasar RXS J1131-1231 at z = 0.654 obtained using the Plateau de Bure Interferometer (P…
