Late-time cosmology with phantom dark-energy in f(Q) gravity [PDF]

Journal of Cosmology and Astroparticle Physics, 2022
Motivated by the exciting features and a recent proposed general form of the function of non-metricity scalar Q, we investigate the cosmological implications in f(Q) gravity, through the resulting effective dark energy sector, extracting analytical ...

Revisiting geodesic observers in cosmology [PDF]

The European Physical Journal C, 2021
AbstractGeodesic observers in cosmology are revisited. The coordinates based on freely falling observers introduced by Gautreau in de Sitter and Einstein-de Sitter spaces (and, previously, by Gautreau and Hoffmann in Schwarzschild space) are extended to general FLRW universes.

“Don't let anybody ever put you down culturally…. it's not good…”: Creating spaces for Blak women's healing

American Journal of Community Psychology, Volume 70, Issue 3-4, Page 352-364, December 2022., 2022
Abstract Research has highlighted the importance of Indigenous knowledge and cultural practice in healing from ongoing histories of trauma, dispossession, and displacement for Indigenous peoples in Australia and elsewhere. Connection with culture, Country, and kinship has been identified as protective factors for Aboriginal social and emotional well ...

Sample Variance in Cosmological Observations with a Narrow Field of View

The Astrophysical Journal, 2023
Surveys with a narrow field of view can play an important role in probing cosmology, but inferences from these surveys suffer from large sample variance, arising from random fluctuations around the cosmic mean.

Modified Gravity and Cosmology [PDF]

, 2021
General Relativity and the $\Lambda$CDM framework are currently the standard lore and constitute the concordance paradigm. Nevertheless, long-standing open theoretical issues, as well as possible new observational ones arising from the explosive ...

The DESI Survey Validation: Results from Visual Inspection of the Quasar Survey Spectra

The Astronomical Journal, 2023
A key component of the Dark Energy Spectroscopic Instrument (DESI) survey validation (SV) is a detailed visual inspection (VI) of the optical spectroscopic data to quantify key survey metrics. In this paper we present results from VI of the quasar survey

Performance of the Quasar Spectral Templates for the Dark Energy Spectroscopic Instrument

The Astronomical Journal, 2023
Millions of quasar spectra will be collected by the Dark Energy Spectroscopic Instrument (DESI), leading to a fourfold increase in the number of known quasars.

Low-Redshift Observational Constraints on Dark Energy Cosmologies [PDF]

Iranian Journal of Astronomy and Astrophysics, 2023
Applying the Markov chain Monte Carlo algorithm and using low-redshift observational data, we put cosmological constraints on dark energy cosmologies. Our main aim is to show the influence of each data sample on the procedure of constraining.

Bayesian Parameterization of Continuum Battery Models from Featurized Electrochemical Measurements Considering Noise**

Batteries &Supercaps, Volume 6, Issue 1, January 2023., 2023
We introduce a computer algorithm that incorporates the experience of battery researchers to extract information from experimental data reproducibly. This enables the fitting of complex models that take up to a few minutes to simulate. For validation, we process full‐cell GITT measurements to characterize the diffusivities of both electrodes non ...
