VIS3COS: III. environmental effects on the star formation histories of galaxies at z~0.8 seen in [OII], H, and Dn4000
Ana Paulino-Afonso, David Sobral, Behnam Darvish +5
[ABRIDGED] We present spectroscopic observations of 466 galaxies in and around a superstructure at targeted by the VIMOS Spectroscopic Survey of a Supercluster in the C…
Unveiling the cause of hybrid morphology radio sources (HyMoRS)
Jeremy J. Harwood, Tessa Vernstrom, Andra Stroe
Hybrid morphology radio sources (HyMoRS) are a rare group of radio galaxies in which differing Fanaroff & Riley morphologies (FR I/II) are observed for each of the two lobes. While…
Chandra Observations of the Spectacular A3411-12 Merger Event
Felipe Andrade-Santos, Reinout J. van Weeren, Gabriella Di Gennaro +17
We present deep Chandra observations of A3411-12, a remarkable merging cluster that hosts the most compelling evidence for electron re-acceleration at cluster shocks to date. Using…
The X-ray and radio activity of typical and luminous Lya emitters from z~2 to z~6: evidence for a diverse, evolving population
João Calhau, David Sobral, Sérgio Santos +6
Despite recent progress in understanding Lyman-alpha (Lya) emitters (LAEs), relatively little is known regarding their typical black hole activity across cosmic time. Here, we stud…
Large Molecular Gas Reservoirs in Star Forming Cluster Galaxies
Joseph Cairns, Andra Stroe, Carlos De Breuck +2
We present CO(2-1) observations of 72 galaxies in the nearby, disturbed Antlia galaxy cluster with the Atacama Pathfinder Experiment (APEX) telescope. The galaxies in our sample ar…
VIS3COS: II. Nature and nurture in galaxy structure and morphology
Ana Paulino-Afonso, David Sobral, Behnam Darvish +7
We study the impact of local density and stellar mass on the morphology of ~500 quiescent (Q) and SFGs from the VIS3COS survey. We perform B/D decomposition of the SBPs and find ~4…
