What do we know about cosmography

European Physical Journal C: Particles and Fields, 2017
In the present paper, we investigate the cosmographic problem using the bias–variance trade-off. We find that both the z-redshift and the $$y=z/(1+z)$$ y = z / ( 1 + z ) -redshift can present a small bias estimation.

Tests of CPT invariance in gravitational waves with LIGO-Virgo catalog GWTC-1

European Physical Journal C: Particles and Fields, 2020
A discovery of gravitational waves from binary black holes raises a possibility that measurements of them can provide strict tests of CPT invariance in gravitational waves.

Multipurpose Transparent Nanocomposites for Gamma Spectroscopy, Pulse Shape Discrimination, Thermal Neutron Detection, Radiation Shielding, and High Refractive Index Applications

Advanced Functional Materials, EarlyView.
Materials exist that are useful for gamma scintillation, radiation shielding, neutron‐gamma pulse shape discrimination (PSD), thermal neutron detection, or high refractive index applications. While certain materials have exhibited optimal performance for each of these applications, none achieve multiple functions.

Very-high energy gamma-ray astronomy: A 23-year success story in high-energy astroparticle physics

, 2012
Very-high energy (VHE) gamma quanta contribute only a minuscule fraction - below one per million - to the flux of cosmic rays. Nevertheless, being neutral particles they are currently the best "messengers" of processes from the relativistic/ultra ...

The Promise of Solid Lubricants for a Sustainable Future

Advanced Materials, EarlyView.
Lubricants are vital for technology, saving energy and resources. The industry seeks sustainable solutions beyond fossil fuels. Solid lubricants offer extremely low friction and reduce environmental impact, especially in harsh conditions. Can these solids truly replace liquid lubricants, or are they limited to extreme applications?

High energy neutrino astronomy: the experimental road [PDF]

Journal of Physics G: Nuclear and Particle Physics, 2003
The next ten years promise to be a particularly exciting decade for high energy neutrino astrophysics. The frontier of TeV and PeV energy is presently being tackled by large, expandable arrays constructed in open water or ice. Detectors tailored to record acoustic, radio, fluorescence or air shower signatures from neutrino interactions at PeV-EeV ...
