Dark Energy from α-attractors: Phenomenology and Observational Constraints

Garcia-Garcia, Carlos; Linder, Eric V.; Ruiz-Lapuente, Pilar; Zumalacaregui, Miguel (NURIS; Energetic Cosmos Laboratory, 2018-03-01)

The possibility of linking inflation and late cosmic accelerated expansion using the α-attractor models has received increasing attention due to their physical motivation. In the early universe, α-attractors provide an ...
Debiasing Cosmic Gravitational Wave Sirens [Article]

Keeley, Ryan E.; Shafieloo, Arman; L'Huillier, Benjamin; Linder, Eric V. (NURIS; Energetic Cosmos Laboratory, 2019-05-27)

Accurate estimation of the Hubble constant, and other cosmological parameters, from distances measured by cosmic gravitational wave sirens requires sufficient allowance for the dark energy evolution. We demonstrate how ...
Deep decarbonisation and growth: challenges and prospects

Developments in Cosmic Growth and Gravitation [Article]

Linder, Eric V. (NURIS; Energetic Cosmos Laboratory, 2019-04-23)

Cosmic surveys of large scale structure have imaged hundreds of millions of galaxies and mapped the 3D positions of over a million. Surveys starting over the next few years will increase these numbers more than tenfold. ...
EDUCATION FOR SUSTAINABLE DEVELOPMENT

Electrodeposited Ni-Sn intermetallic alloy electrode for 3D sulfur battery

Tolegen, B.; Adi, A.; Aishova, A.; Bakenov, Z.; Nurpeissova, A. (Materials Today: Proceedings, 2017-01-01)

Abstract 3D architecture appeared to be a promising design to enhance the performance of the Lithium-ion batteries by shortening the lithium ion diffusion path and increasing the energy density per unit area. In this paper, ...
Emptying Water Towers? Impacts of Future Climateand Glacier Change on River Discharge in theNorthern Tien Shan, Central Asia

Zhumabayev, Dauren; Shahgedanova, Maria; Afzal, Muhammad; Hagg, Wilfried; Kapitsa, Vassiliy; Kasatkin, Nikolay; Mayr, Elizabeth; Rybak, Oleg; Saidaliyeva, Zarina; Severskiy, Igor; Usmanova, Zamira; Wade, Andrew; Yaitskaya, Natalia (MDPI, 2020-02-26)

mpacts of projected climate and glacier change on river discharge in five glacierized catchments in the northern Tien Shan, Kazakhstan are investigated using a conceptual hydrological model HBV-ETH. Regional climate model ...
The End of Cosmic Growth

Linder, Eric V.; Polarski, David (NURIS; Energetic Cosmos Laboratory, 2018-10-24)

The growth of large scale structure is a battle between gravitational attraction and cosmic acceleration. We investigate the future behavior of cosmic growth under both general relativity (GR)and modified gravity during ...
ENERGY, SCIENCE AND INNOVATION IN SWITZERLAND

Roesle, Phillippe (International Scientific and University Conference. "Climate Change and CO2 Emission Reduction" 12-13 July, 2017, 2017-07)
Energy Storage: a Critical Component of Future Energy

Rakymbay, Ruslan (International Scientific and University Conference. "Climate Change and CO2 Emission Reduction" 12-13 July, 2017, 2017-07-13)
Eternal and Evanescent Black Holes: It’s All Done With Mirrors

Good, Michael R.R.; Linder, Eric V. (NURIS; Energetic Cosmos Laboratory, 2017-11-27)

The analogy between black hole radiation and accelerating mirror radiation (the dynamical Casimir effect) is particularly strong for mirror trajectories giving rise to a constant thermal flux of particles. We present new ...
Finite Energy but Infinite Entropy Production from Moving Mirrors

Good, Michael R.R.; Linder, Eric V. (NURIS; Energetic Cosmos Laboratory, 2018-07-20)

Accelerating mirrors provide a simple conceptual laboratory for studying particle production and the relation between trajectory and particle, energy, and entropy fluxes. We focus on the relation between energy and entropy, ...
FUTURE POWER SYSTEMS: CHALLENGES AND SOLUTIONS

Ni, Alexander (International Scientific and University Conference. "Climate Change and CO2 Emission Reduction".12-13 July, 2017, 2017-07)
Gravity’s Islands: Parametrizing Horndeski Stability

Denissenya, Mikhail; Linder, Eric V. (NURIS; Energetic Cosmos Laboratory, 2018-07-31)

Cosmic acceleration may be due to modified gravity, with effective field theory or property functions describing the theory. Connection to cosmological observations through practical parametrization of these functions is ...
GW170817 Most Likely Made a Black Hole

Pooley, David; Kumar, Pawan; Wheeler, J. Craig; Grossan, Bruce (NURIS; Energetic Cosmos Laboratory, 2018-05-14)

There are two outstanding issues regarding the neutron-star merger event GW170817: the nature of the compact remnant and the interstellar shock. The mass of the remnant of GW170817, ∼2.7 M⊙, implies the remnant could be ...
