The VISTA Deep Extragalactic Observations (VIDEO) survey
(Oxford University Press, 2013)
In this paper we describe the first data release of the the Visible and Infrared Survey Telescope
for Astronomy (VISTA) Deep Extragalactic Observations (VIDEO) survey. VIDEO is a
12 degree2 survey in the near-infrared ...
A null test to probe the scale dependence of the growth of structure as a test of general relativity
(Oxford University Press, 2019)
The main science driver for the coming generation of cosmological surveys is understanding dark energy that relies on testing general relativity on the largest scales. Once we move beyond the simplest explanation for dark ...
The impact of the connectivity of the cosmic web on the physical properties of galaxies at its nodes
(Oxford University Press, 2019)
We investigate the impact of the number of filaments connected to the nodes of the cosmic web on the physical properties of their galaxies using the Sloan Digital Sky Survey. We compare these measurements to the cosmological ...
Cosmic evolution of star-forming galaxies to z 1.8 in the faint low-frequency radio source population
(Oxford University Press, 2019)
We study the properties of star-forming galaxies selected at 610 MHz with the GMRT in a survey covering ∼1.86 deg2 down to a noise of ∼7.1 μJy beam−1. These were identified by combining multiple classification diagnostics: ...
Non-Gaussianity constraints using future radio continuum surveys and the multitracer technique
(Oxford University Press, 2019)
Tighter constraints on measurements of primordial non-Gaussianity (PNG) will allow the differentiation of inflationary scenarios. The cosmic microwave background bispectrum – the standard method of measuring the local ...
Developing a unified pipeline for large-scale structure data analysis with angular power spectra – II. A case study for magnification bias and radio continuum surveys
(Oxford University Press, 2019)
Following on our purpose of developing a unified pipeline for large-scale structure data analysis with angular power spectra, we now include the weak lensing effect of magnification bias on galaxy clustering in a publicly ...
Testing gravity using large-scale redshift-space distortions
(Oxford University Press, 2013)
We use luminous red galaxies from the Sloan Digital Sky Survey (SDSS) II to test
the cosmological structure growth in two alternatives to the standard cold dark matter
( CDM)+general relativity (GR) cosmological model. ...
Testing homegeneity with Galaxy Star formation histories
(IOP Publishing, 2013)
Observationally confirming spatial homogeneity on sufficiently large cosmological scales is of importance to test
one of the underpinning assumptions of cosmology, and is also imperative for correctly interpreting dark ...
SN Ia host galaxy properties from Sloan Digital Sky Survey-II spectroscopy
(Oxford University Press, 2013)
We study the stellar populations of Type Ia supernova (SN Ia) host galaxies using Sloan
Digital Sky Survey (SDSS)-II spectroscopy. The main focus is on the relationships of SN Ia
properties with stellar velocity dispersion ...
