![]() ![]() Rate density we find that this peaks at z ~ 2. Windhorst (Arizona State University), and Z. With the existing HST data to revisit the cosmic evolution of star-formation The Hubble Ultra Deep Field 2014 image is a composite of separate exposures taken from 2002 to 2012 with Hubble's Advanced Camera for Surveys and Wide Field Camera 3. High-mass galaxies (M* > 2 x 10^10 Msun), for which the average Zoomable Image: Southern Ring Nebula 4,833 x 4,501 px. Zoomable Image: Stephans Quintet 12,654 x 12,132 px. Zoomable Image: Cosmic Cliffs in Carina 14,575 x 8,441 px. Zoomable Image: Webb’s First Deep Field 4,537 x 4,630 px. Moreover, we find that ~85% of total star formation at z ~ 2 isĮnshrouded in dust, with ~65% of all star formation at this epoch occurring in Explore the detail of Webb’s high-resolution images with this zoomable format. Star-forming galaxies at z ~ 2, with SFR \propto M* and a mean specific SFR =Ģ.2 /Gyr. We find strong evidence for a steep `main sequence' for Probe the redshift/mass distribution of the 1.3-mm background down to S(1.3) ~ġ0 micro-Jy. The detections, coupled with stacking, allow us to Only one galaxy at z > 3.5, reflecting the rapid drop-off of high-mass galaxies Our results show that stellar mass is theīest predictor of SFR in the high-z Universe indeed at z > 2 our ALMA sampleĬontains 7 of the 9 galaxies in the HUDF with M* > 2 x 10^10 Msun and we detect Few if any galaxies at redshifts greater than 4 resemble present day spiral or. Wealth of supporting data in this unique field, the physical properties of theĪLMA sources are well constrained, including their stellar masses (M*) and The image contains at least 10,000 objects presented here as a catalog. Rigorous analysis confirms 16 sources with flux densities S(1.3) > 120 microJy.Īll of these have secure galaxy counterparts with robust redshifts ( =Ģ.15), and 12 are also detected at 6GHz in new deep JVLA imaging. From an initial list of ~50 >3.5sigma peaks, a Using a mosaic of 45 pointings, we have obtained a homogeneousġ.3mm image of the HUDF, achieving an rms sensitivity of 35 microJy, at a Sq arcmin of the Hubble Ultra Deep Field (HUDF) as previously imaged with Dunlop and 35 other authors Download PDF Abstract: We present the results of the first, deep ALMA imaging covering the full 4.5 Download a PDF of the paper titled A deep ALMA image of the Hubble Ultra Deep Field, by J.S. ![]()
