Improving photometric redshift estimation using GPz: size information, post processing and improved photometry
(Oxford University Press, 2017)
The next generation of large-scale imaging surveys (such as those conducted with the Large Synoptic Survey Telescope and Euclid) will require accurate photometric redshifts in order to optimally extract cosmological ...
The kinematic dipole in galaxy redshift surveys
(IOP Publishing, 2018)
In the concordance model of the Universe, the matter distribution { as observed in galaxy number
counts or the intensity of line emission (such as the 21cm line of neutral hydrogen) - should have
a kinematic dipole due ...
Mining the Herschel-Astrophysical Terahertz Large Area Survey: submillimetre-selected blazars in equatorial fields
(Oxford University Press, 2013)
The Herschel-Astrophysical Terahertz Large Area Survey (H-ATLAS) provides an unprecedented
opportunity to search for blazars at sub-mm wavelengths. We cross-matched the Faint
Images of the Radio Sky at Twenty-cm (FIRST) ...
MUFASA: The strength and evolution of galaxy conformity in various tracers
(Oxford University Press, 2017)
We investigate galaxy conformity using the Mufasa cosmological hydrodynamical
simulation. We show a bimodal distribution in galaxy colour with radius, albeit
with too many low-mass quenched satellite galaxies compared ...
Spin coating immobilisation of C-N-TiO2 Co-Doped nano catalyst on glass and application for photocatalysis or as electron transporting layer for perovskite solar cells
(MDPI, 2020)
Producingactivethinfilmscoatedonsupportsresolvesmanyissuesofpowder-basedphoto catalysis and energy harvesting. In this study, thin films of C-N-TiO2 were prepared by dynamic spin coating of C-N-TiO2 sol-gel on glass support. ...
The evolving role of science in society
(José Frantz, 2020)
The world is experiencing a traumatic change brought about by the Covid-19 pandemic. It is traumatic because it is sudden and affects everyone around the globe at once. Nothing like this has ever happened so rapidly before, ...
Investigation of excited 0+ states in 160Er populated via the (p, t) two-neutron transfer reaction
(EDP Sciences, 2018)
Many efforts have been made in nuclear structure physics to interpret the nature of low-lying excited 0+ states in well-deformed rare-earth nuclei. However, one of the difficulties in resolving the nature of these states ...
Self-catalytic growth of tin oxide nanowires by chemical vapor deposition process
(Hindawi, 2013)
We report on the synthesis of tin oxide (SnO2) nanowires by a chemical vapor deposition (CVD) process. Commercially bought
SnO nanopowders were vaporized at 1050∘C for 30 minutes with argon gas continuously passing through ...
Gaia Data Release 1. Open cluster astrometry: performance, limitations, and future prospects
(EDP Sciences, 2017)
CONTEXT: The first Gaia Data Release contains the Tycho-Gaia Astrometric Solution (TGAS). This is a subset of about 2 million stars for which,
besides the position and photometry, the proper motion and parallax are ...
Aligned metal absorbers and the ultraviolet background at the end of reionization
(Oxford University Press, 2018)
We use observations of spatially-aligned C ii, C iv, Si ii, Si iv, and O i absorbers to probe the
slope and intensity of the ultraviolet background (UVB) at z ∼ 6. We accom- plish this by comparing
observations with ...
