Exploring the Universe via the Wide, Deep Near-infrared Imaging ESO Public Survey SHARKS
Helmut Dannerbauer, Aurelio Carnero, Nicholas Cross +1
The ESO Public Survey Southern H-ATLAS Regions Ks-band Survey (SHARKS) comprises 300 square degrees of deep imaging at 2.2 microns (the Ks band) with the VISTA InfraRed CAMera (VIR…
The 700 ks Chandra Spiderweb Field II: Evidence for inverse-Compton and thermal diffuse emission in the Spiderweb galaxy
P. Tozzi, R. Gilli, A. Liu +22
We present the X-ray imaging and spectral analysis of the diffuse emission around the Spiderweb galaxy at z=2.16 and of its nuclear emission, based on a deep (700 ks) Chandra obser…
Signs of environmental effects on star-forming galaxies in the Spiderweb protocluster at z=2.16
Jose Manuel Pérez-Martínez, Helmut Dannerbauer, Tadayuki Kodama +11
We use multi-object near-infrared (NIR) spectroscopy with VLT/KMOS to investigate the role of the environment in the evolution of the ionized gas properties of narrow-band selected…
The Young and the Wild: What happens to Protoclusters forming at z = 4?
Rhea-Silvia Remus, Klaus Dolag, Helmut Dannerbauer
Using one of the largest volumes of the hydrodynamical cosmological simulation suit Magneticum, we study the evolution of protoclusters identified at redshift = 4, with properties…
The GLEAMing of the first supermassive black holes: II. A new sample of high-redshift radio galaxy candidates
J. W. Broderick, G. Drouart, N. Seymour +27
While unobscured and radio-quiet active galactic nuclei are regularly being found at redshifts , their obscured and radio-loud counterparts remain elusive. We build upon our…
High-z Sudoku: A diagnostic tool for identifying robust (sub)mm redshifts
Tom J. L. C. Bakx, Helmut Dannerbauer
We present methods to (i) graphically identify robust redshifts using emission lines in the (sub)mm regime, (ii) evaluate the capabilities of different (sub)mm practices for measur…
The 700 ks Chandra Spiderweb Field I: evidence for widespread nuclear activity in the Protocluster
P. Tozzi, L. Pentericci, R. Gilli +21
(Abridged) We present an analysis of the 700 ks Chandra ACIS-S observation of the field around the Spiderweb Galaxy at z=2.156, focusing on the nuclear activity in the associated l…
Submillimetre galaxies in two massive protoclusters at z = 2.24: witnessing the enrichment of extreme starbursts in the outskirts of HAE density peaks
Yuheng Zhang, Xian Zhong Zheng, Dong Dong Shi +18
Submillimetre galaxies represent a rapid growth phase of both star formation and massive galaxies. Mapping SMGs in galaxy protoclusters provides key insights into where and how the…
Tomography of the environment of the COSMOS/AzTEC-3 submillimeter galaxy at z=5.3 revealed by Lyalpha and MUSE observations
L. Guaita, M. Aravena, S. Gurung-Lopez +8
We study the members of the protocluster around AzTEC3 submillimeter galaxy at z=5.3. We analyzed the data from the MUSE instrument in an area of 1.4x1.4 arcmin^2 around AzTEC3 and…
The Bright Extragalactic ALMA Redshift Survey (BEARS) I: redshifts of bright gravitationally-lensed galaxies from the Herschel ATLAS
S. A. Urquhart, G. J. Bendo, S. Serjeant +53
We present spectroscopic measurements for 71 galaxies associated with 62 of the brightest high-redshift submillimeter sources from the Southern fields of the Herschel Astrophysical…
Feeding the spider with carbon -- [CII] emission from the circum galactic medium and active galactic nucleus
Carlos De Breuck, Andreas Lundgren, Bjorn Emonts +3
We present the detection of [CII] 158um emission from the Spiderweb galaxy at z=2.1612 using the Atacama Pathfinder EXperiment. The line profile splits into an active galactic nucl…
