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 ... -
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 ... -
Measuring the HI mass function below the detection threshold
(Royal Astronomical Society, 2020)We present a Bayesian stacking technique to directly measure the H I mass function (HIMF) and its evolution with redshift using galaxies formally below the nominal detection threshold. We generate galaxy samples over several ... -
Properties of submillimeter galaxies in the CANDELS GOODS-south field
(American Physical Society, 2014)We derive physical properties of 10 submillimeter galaxies located in the CANDELS coverage of the GOODS-S field. The galaxies were first identified as submillimeter sources with the LABOCA bolometer and subsequently targeted ... -
The star formation rates of QSOs
(Royal Astronomical Society, 2022)We examine the far-IR properties of a sample of 5391 optically selected QSOs in the 0.5 < z < 2.65 redshift range down to log [νLν,2500(erg/s)] > 44.7, using SPIRE data from Herschel-ATLAS. We split the sample in a grid ... -
The star-formation history of mass-selected galaxies from the VIDEO survey
(Oxford University Press, 2014)We measure star formation rates (SFRs) and specific SFRs (SSFRs) of Ks-selected galaxies from the VISTA Deep Extragalactic Observations survey by stacking 1.4 GHz Very Large Array data. We split the sample, which spans 0 ...
