How well can we measure the stellar mass of a galaxy: The impact of the assumed star formation history model in SED fitting
(IOP Publishing, 2020)
The primary method for inferring the stellar mass (M∗) of a galaxy is through spectral energy distribution (SED) modeling. However, the technique rests on assumptions such as the galaxy star formation history and dust ...
A flexible method for estimating luminosity functions via Kernel Density Estimation
(IOP Publishing, 2020)
We propose a flexible method for estimating luminosity functions (LFs) based on kernel density
estimation (KDE), the most popular nonparametric density estimation approach developed in modern
statistics, to overcome ...
Non-linear damping of superimposed primordial oscillations on the matter power spectrum in galaxy surveys
(IOP Publishing Ltd, 2020)
Galaxy surveys are an important probe for superimposed oscillations on the primordial power spectrum of curvature perturbations, which are predicted in several theoretical
models of inflation and its alternatives. In order ...
Improvements in cosmological constraints from breaking growth degeneracy
(EDP Sciences, 2020)
The key probes of the growth of a large-scale structure are its rate f and amplitude σ8. Redshift space distortions in the galaxy power spectrum allow us to measure only the combination fσ8, which can be used to constrain ...
Planck 2018 results VIII. Gravitational lensing
(EDP Sciences, 2020)
We present measurements of the cosmic microwave background (CMB) lensing potential using the final Planck 2018 temperature and polarization data. Using polarization maps filtered to account for the noise anisotropy, we ...
The VLA-COSMOS 3 GHz Large Project: Evolution of specific star formation rates out to z∼5
(IOP Publishing, 2020)
We provide a coherent, uniform measurement of the evolution of the logarithmic star formation rate
(SFR) – stellar mass (M∗) relation, called the main sequence of star-forming galaxies (MS), for starforming and all galaxies ...
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 ...
