Colloidal Opaline Composites as Throughput‐Scalable, Fully Transparent, and Color‐Tunable Radiative Cooling Exterior Films for Outdoor Photovoltaics

open access: yesAdvanced Functional Materials, EarlyView.
Particular thermal metamaterials are widely used as daytime radiative coolers merely by embedding thermally emissive nanoparticles (NPs) in liquid resins to form scalable, yet highly efficient cooling films in a cost‐effective way. However, randomly dispersed NPs, prevalently used thus far, cause strong scattering, limiting NP content and cooling ...

Mock 2dF and SDSS galaxy redshift surveys [PDF]

open access: yes, 1998
We present a comprehensive set of mock 2dF and SDSS galaxy redshift surveys constructed from a set of large, high-resolution cosmological N-body simulations.

Cosmology with Redshift Surveys of Radio Sources [PDF]

open access: yes, 1998
We use the K-z relation for radio galaxies to illustrate why it has proved difficult to obtain definitive cosmological results from studies based entirely on catalogues of the brightest radio sources, e.g. 3C. To improve on this situation we have been undertaking redshift surveys of complete samples drawn from the fainter 6C and 7C radio catalogues. We

WiggleZ Dark Energy Survey: Cosmological neutrino mass constraint from blue high-redshift galaxies [PDF]

open access: yes, 2012
The absolute neutrino mass scale is currently unknown, but can be constrained by cosmology. The WiggleZ high redshift, star-forming, and blue galaxy sample offers a complementary data set to previous surveys for performing these measurements, with ...

Tailored Reconstruction of Polycrystalline CuO Nanorods Promotes C─C Coupling in CO2 Electroreduction

open access: yesAdvanced Functional Materials, EarlyView.
Controlling the polycrystallinity of CuO nanorods enables directional reconstruction into rod‐like structures that stabilize Cu(OH)2 and increase Cu+ ratios, while modulating interfacial water dynamics to enhance C─C coupling and boost C2+ product formation in CO2 electroreduction.

The Intracluster Light Analysis of the Most Evolved Systems of Galaxies: Fossil Groups

open access: yesThe Astrophysical Journal Letters
We present the analysis of the intracluster light (ICL) in three fossil groups, RX J085640.72+055347.36, RX J1136+0713, and RX J1410+4145, at z ∼ 0.1. We used two optical broadband filters, F435W and F606W, observed with the Hubble Space Telescope, and ...

2dF QSO Redshift Survey

open access: yes, 2000
With approximately 6000 QSO redshifts,the 2dF QSO redshift survey is already the biggest complete QSO survey. The aim for the survey is to have 25000 QSO redshifts, providing an order of magnitude increase in QSO clustering statistics. We first describe the observational parameters of the 2dF QSO survey.

Redshift sensitivities of dark energy surveys

open access: yesPhysical Review D, 2006
Great uncertainty surrounds dark energy, both in terms of its physics, and the choice of methods by which the problem should be addressed. Here we quantify the redshift sensitivities offered by different techniques. We focus on the three methods most adept at constraining w, namely supernovae, cosmic shear, and baryon oscillations.

Cosmological Constraints with Clustering-Based Redshifts

open access: yes, 2016
We demonstrate that observations lacking reliable redshift information, such as photometric and radio continuum surveys, can produce robust measurements of cosmological parameters when empowered by clustering-based redshift estimation. This method infers
