Galaxy and Mass Assembly (GAMA): Demonstrating the power of WISE in the study of Galaxy Groups to z < 0.1
(IOP Publishing, 2020)
Combining high-fidelity group characterisation from the Galaxy and Mass Assembly (GAMA) survey
and source-tailored z < 0.1 photometry from the WISE survey, we present a comprehensive study of the
properties of ungrouped ...
The XXL survey XLII. Detection and characterization of the galaxy population of distant galaxy clusters in the XXL-N/VIDEO field: A tale of variety
(ESO, 2020)
Context. Distant galaxy clusters provide an effective laboratory in which to study galaxy evolution in dense environments and at early cosmic times.
Aims. We aim to identify distant galaxy clusters as extended X-ray sources ...
Scalar-tensor theories of gravity, neutrino physics, and the H0 tension
(IOP Publishing, 2020)
We use Planck 2018 data to constrain the simplest models of scalar-tensor theories
characterized by a coupling to the Ricci scalar of the type F(σ)R with F(σ) = N2
pl + ξσ2
.
We update our results with previous Planck ...
The role of environment in galaxy evolution in the servs survey. I. density maps and cluster candidates
(The American Astronomical Society, 2020)
We use photometric redshifts derived from new u-band through 4.5 μm Spitzer IRAC photometry in the 4.8 deg2 of
the XMM-LSS field to construct surface density maps in the redshift range of 0.1–1.5. Our density maps ...
Extending the variability selection of active galactic nuclei in the W-CDF-S and SERVS/SWIRE region
(EDP Sciences, 2020)
Variability has proven to be a powerful tool to detect active galactic nuclei (AGN) in multi-epoch surveys. The new-generation facilities expected to become operational in the next few years will mark a new era in time-domain ...
Full-sky bispectrum in redshift space for 21cm intensity maps
(IOP Publishing, 2020)
We compute the tree-level bispectrum of 21cm intensity mapping after reionisation. We work in directly observable angular and redshift space, focusing on equal-redshift
correlations and thin redshift bins, for which the ...
The Hubble constant tension with next-generation galaxy surveys
(IOP Publishing Ltd, 2020)
The rate at which the universe is expanding today is a fundamental parameter in
cosmology which governs our understanding of structure formation and dark energy. However, current measurements of the Hubble constant, H0, ...
The impact of wind scalings on stellar growth and the baryon cycle in cosmological simulations
(Oxford University Press, 2020)
Many phenomenologically successful cosmological simulations employ kinetic winds to model galactic outflows. Yet systematic studies of how variations in kinetic wind scalings might alter observable galaxy properties are ...
A lack of evolution in the very bright end of the galaxy luminosity function from z 8 to 10
(Oxford University Press, 2020)
ABSTRACT
We utilize deep near-infrared survey data from the UltraVISTA fourth data release (DR4) and the VIDEO survey, in combination with overlapping optical and Spitzer data, to search for bright star-forming galaxies ...
The rest-frame UV luminosity function at z 4: A significant contribution of AGNs to the bright end of the galaxy population
(Oxford University Press, 2020)
We measure the rest-frame ultraviolet (UV) luminosity function (LF) at z ∼ 4 self-consistently over a wide range in absolute magnitude (−27 ≲ MUV ≲ −20). The LF is measured with 46 904 sources selected using a photometric ...
