An ALMA survey of the SCUBA-2 CLS UDS field: physical properties of 707 sub-millimetre galaxies
Thomson, A. P.; Ivison, R. J.; Scott, D. +27 more
We analyse the physical properties of a large, homogeneously selected sample of ALMA-located sub-millimetre galaxies (SMGs). This survey, AS2UDS, identified 707 SMGs across the ∼1 deg2 field, including ∼17 per cent, which are undetected at K ≳ 25.7 mag. We interpret their ultraviolet-to-radio data using magphys and determine a median re…
Galaxy And Mass Assembly (GAMA): a forensic SED reconstruction of the cosmic star formation history and metallicity evolution by galaxy type
Hopkins, Andrew M.; Driver, Simon P.; Robotham, Aaron S. G. +9 more
We apply the spectral energy distribution (SED) fitting code PROSPECT to multiwavelength imaging for ∼7000 galaxies from the GAMA survey at z < 0.06, in order to extract their star formation histories. We combine a parametric description of the star formation history with a closed-box evolution of metallicity where the present-day gas-phase met…
Galaxy And Mass Assembly (GAMA): assimilation of KiDS into the GAMA database
Driver, Simon P.; Robotham, Aaron S. G.; Bellstedt, Sabine +9 more
The Galaxy And Mass Assembly Survey (GAMA) covers five fields with highly complete spectroscopic coverage (>95 per cent) to intermediate depths (r < 19.8 or i < 19.0 mag), and collectively spans 250 deg2 of equatorial or southern sky. Four of the GAMA fields (G09, G12, G15, and G23) reside in the European Southern Observatory (…
Megaparsec-scale structure around the protocluster core SPT2349-56 at z = 4.3
Greve, Thomas R.; Spilker, Justin; Aravena, Manuel +20 more
We present an extensive ALMA spectroscopic follow-up programme of the z = 4.3 structure SPT2349-56, one of the most actively star-forming protocluster cores known, to identify additional members using their [C II] 158 µm and CO(4-3) lines. In addition to robustly detecting the 14 previously published galaxies in this structure, we identify a…
High molecular gas content and star formation rates in local galaxies that host quasars, outflows, and jets
Thomson, A. P.; Alexander, D. M.; Mainieri, V. +11 more
We use a sample of powerful $z\, \approx \, 0.1$ type 2 quasars ('obscured'; log [LAGN/erg s $^{-1}]\, \gtrsim \, 45$ ), which host kpc-scale ionized outflows and jets, to identify possible signatures of AGN feedback on the total molecular gas reservoirs of their host galaxies. Specifically, we present Atacama Pathfinder EXperiment (APE…
The Hi-GAL catalogue of dusty filamentary structures in the Galactic plane
Umana, G.; Moore, T. J. T.; Palmeirim, P. +27 more
The recent data collected by Herschel have confirmed that interstellar structures with a filamentary shape are ubiquitously present in the Milky Way. Filaments are thought to be formed by several physical mechanisms acting from large Galactic scales down to subparsec fractions of molecular clouds, and they might represent a possible link between s…
LEGO - II. A 3 mm molecular line study covering 100 pc of one of the most actively star-forming portions within the Milky Way disc
Weiss, A.; Evans, N. J.; Goldsmith, P. F. +20 more
The current generation of (sub)mm-telescopes has allowed molecular line emission to become a major tool for studying the physical, kinematic, and chemical properties of extragalactic systems, yet exploiting these observations requires a detailed understanding of where emission lines originate within the Milky Way. In this paper, we present 60 arcs…
The evolution of rest-frame UV properties, Ly α EWs, and the SFR-stellar mass relation at z ∼ 2-6 for SC4K LAEs
da Cunha, E.; Arrabal Haro, P.; Sobral, D. +6 more
We explore deep rest-frame UV to FIR data in the COSMOS field to measure the individual spectral energy distributions (SED) of the ∼4000 SC4K (Sobral et al.) Lyman α (Ly α) emitters (LAEs) at z ∼ 2-6. We find typical stellar masses of 109.3 ± 0.6 M⊙ and star formation rates (SFR) of SFR_SED=4.4^{+10.5}_{-2.4} M⊙ yr…
JINGLE - IV. Dust, H I gas, and metal scaling laws in the local Universe
Clements, D. L.; Lin, L.; Saintonge, A. +29 more
Scaling laws of dust, H I gas, and metal mass with stellar mass, specific star formation rate, and metallicity are crucial to our understanding of the build-up of galaxies through their enrichment with metals and dust. In this work, we analyse how the dust and metal content varies with specific gas mass (MH I/M⋆) across a div…
Self-gravitating filament formation from shocked flows: velocity gradients across filaments
Ostriker, Eve C.; Chen, Che-Yu; Mundy, Lee G. +2 more
In typical environments of star-forming clouds, converging supersonic turbulence generates shock-compressed regions, and can create strongly magnetized sheet-like layers. Numerical magnetohydrodynamic simulations show that within these post-shock layers, dense filaments and embedded self-gravitating cores form via gathering material along the magn…
