The ramp-up of interstellar medium enrichment at z>4
(2021-11-04)
Fluorine is one of the most interesting elements for nuclear and stellar astrophysics 1,2. Fluorine abundance was first measured for stars other than the Sun in 1992 1, then for a handful of metal-poor stars 3, which are ...
Cosmic evolution of the H2 mass density and the epoch of molecular gas
(2021-05-05)
We present new empirical constraints on the evolution of ρ H2, the cosmological mass density of molecular hydrogen, back to z ≈ 2.5. We employ a statistical approach measuring the average observed 850 μm flux density of ...
Revealing the Stellar Mass and Dust Distributions of Submillimeter Galaxies at Redshift 2
(2019-07-03)
We combine high-resolution ALMA and HST/CANDELS observations of 20 submillimeter galaxies (SMGs), predominantly from the AS2UDS survey at z ≃ 2, with bright rest-frame optical counterparts () to investigate the resolved ...
An ALMA survey of the SCUBA-2 Cosmology Legacy Survey UKIDSS/UDS field : Source catalogue and properties
(2019-06-06)
We present the catalogue and basic properties of sources in AS2UDS, an 870-\mum continuum survey with the Atacama Large Millimetre/sub-millimetre Array (ALMA) of 716 single-dish sub-millimetre sources detected in the ...
The Dynamics and Distribution of Angular Momentum in HiZELS Star-Forming Galaxies at z = 0.8 - 3.3
(2019-06)
We present adaptive optics assisted integral field spectroscopy of 34 star-forming galaxies at z = 0.8-3.3 selected from the HiZELS narrow-band survey. We measure the kinematics of the ionized interstellar medium on ∼1 kpc ...
The Halo Mass of Optically Luminous Quasars at z ,F≈ ,F1-2 Measured via Gravitational Deflection of the Cosmic Microwave Background
(2019-03-27)
We measure the average deflection of cosmic microwave background photons by quasars at 〈Z〉= 1.7. Our sample is selected from the Sloan Digital Sky Survey to cover the redshift range 0.9 ≤z≤2.2 with absolute i-band magnitudes ...
The linear bias of radio galaxies at z~0.3 via cosmic microwave background lensing
(2019-02-26)
We present a new measurement of the linear bias of radio loud active galactic nuclei (RLAGN) at $z\approx0.3$ and $L_{\rm 1.4GHz}>10^{23}\,{\rm W\,Hz^{-1}}$ selected from the Best & Heckman (2012) sample, made by ...
The nature of the variable millimetre-selected AGN in the Brightest Cluster Galaxy of Abell 851
(2018-11-21)
We present the detection of a bright 3mm continuum source in the brightest cluster galaxy (BCG) in Abell 0851 (z = 0.411) with the NOrthern Extended Millimeter Array (NOEMA). When this detection is compared to other ...
A Magnified View of Circumnuclear Star Formation and Feedback around an Active Galactic Nucleus at z = 2.6
(2018-10-10)
We present Atacama Large Millimeter/submillimeter Array observations of an intrinsically radio-bright (L 1.4 GHz = (1.7 ± 0.1) ×10 25 W Hz -1) and infrared luminous (L IR ≈ 10 13 L o) galaxy at z = 2.6. The infrared-to-radio ...
A direct calibration of the IRX-β relation in Lyman-break Galaxies at z=3-5
(2018-10)
We use a sample of 4209 Lyman-break galaxies (LBGs) at z ≃ 3, 4, and 5 in the UKIRT Infrared Deep Sky Survey Ultra Deep Survey field to investigate the relationship between the observed slope of the stellar continuum ...
