Info Science Highlight: A dynamically cold disk galaxy in the early Universe Apr 24, 2020 05:50 PM Due to the COVID-19 outbreak, ALMA Science Operations have been suspended and the Cycle 8 Call for Proposals has been delayed until 2021 March. The start of ALMA Cycle 8 will now be 2021 October. ALMA continues to carefully monitor the evolving global situation regarding the COVID-19 pandemic and will post ALMA-related updates as News Items to the Science Portal. In a recent paper , Rizzo and collaborators present an image reconstruction of a dynamically cold, highly star-forming, rotating disk in galaxy SPT–S J041839–4751.9, at redshift z = 4.2, which is strongly gravitationally lensed by a foreground galaxy at z = 0.263. The top panel shows the e mission of the 158-μm fine-structure line of ionized carbon [C II ] integrated across a velocity range of 721 km s −1 (zeroth-moment map), as observed with ALMA. The beam size, shown as a white ellipse on the lower left corner, is 0.19″ × 0.17″ at a position angle of −85.22°. The reconstructed image of the z=4.2 galaxy is shown in the bottom panel: it is a typical dusty starburst, with global star-forming and dust properties that are in agreement with current numerical simulations and observations. The authors also derived a rotation curve with the typical shape of nearby massive spiral galaxies, which demonstrates that at least some young galaxies are dynamically akin to those observed in the local Universe, and only weakly affected by extreme physical processes.
