Gravitational wave induced baryon acoustic oscillations

open access: yesSciPost Physics, 2022
We study the impact of gravitational waves originating from a first order phase transition on structure formation. To do so, we perform a second order perturbation analysis in the $1+3$ covariant framework and derive a wave equation in which second ...

Systematic treatment of non-linear effects in Baryon Acoustic Oscillations

open access: yesEPJ Web of Conferences, 2016
In this contribution we will discuss the non-linear effects in the baryon acoustic oscillations and present a systematic and controllable way to account for them within time-sliced perturbation theory.

Model-independent traversable wormholes from baryon acoustic oscillations

open access: yesPhysics of the Dark Universe, 2023
In this paper, we investigate the model-independent traversable wormholes from baryon acoustic oscillations. Firstly, we place the statistical constraints on the average dark energy equation of state $\omega_{av}$ by only using BAO data.

Angular Baryon Acoustic Oscillation measure at z=2.225 from the SDSS quasar survey [PDF]

open access: green, 2018
Following a quasi model-independent approach we measure the transversal BAO mode at high redshift using the two-point angular correlation function (2PACF).

Uncorrelated Estimations of H0 Redshift Evolution from DESI Baryon Acoustic Oscillation Observations

open access: goldThe Astrophysical Journal Letters
The Dark Energy Spectroscopic Instrument (DESI) collaboration recently released the first-year data of baryon acoustic oscillations (BAOs). Based on the five different tracers, the cosmological constraint shows a hint of deviation from the standard ΛCDM ...

Probing Cosmology with Baryon Acoustic Oscillations Using Gravitational Waves

open access: yesThe Astrophysical Journal, 2023
The third-generation (3G) gravitational wave (GW) detectors such as the Einstein Telescope or Cosmic Explorer are expected to play an important role in cosmology. With the help of 3G detectors, we will be able to probe large-scale structure features such

Baryon Acoustic Oscillations from Integrated Neutral Gas Observations: an instrument to observe the 21cm hydrogen line in the redshift range 0.13 < z < 0.45 – status update

open access: yesAnais da Academia Brasileira de Ciências, 2021
BINGO (BAO from Integrated Neutral Gas Observations) is a unique radio telescope designed to map the intensity of neutral hydrogen distribution at cosmological distances, making the first detection of Baryon Acoustic Oscillations (BAO) in the frequency ...

Low-redshift estimates of the absolute scale of baryon acoustic oscillations

open access: yesEuropean Physical Journal C: Particles and Fields, 2023
Measurements of the characteristic length scale $$r_s$$ r s of the baryon acoustic oscillations (BAO) provide a robust determination of the distance-redshift relation.

Living on the Fermi edge: On baryon transport and Fermi condensation

open access: yesPhysics Letters B, 2022
The transfer function of the baryon power spectrum from redshift z≈1100 to today has recently been, for the first time, determined from data by Pardo and Spergel.

Bayesian comparison of interacting modified holographic Ricci dark energy scenarios

open access: yesEuropean Physical Journal C: Particles and Fields, 2021
We perform a Bayesian model selection analysis for interacting scenarios of dark matter and modified holographic Ricci dark energy (MHRDE) with linear interacting terms.
