CMB distance priors revisited: effects of dark energy dynamics, spatial curvature, primordial power spectrum, and neutrino parameters
Zhongxu Zhai, Chan-Gyung Park, Yun Wang +1
As a physical and sufficient compression of the full CMB data, the CMB distance priors, or shift parameters, have been widely used and provide a convenient way to include CMB data…
Brans-Dicke gravity with a cosmological constant smoothes out CDM tensions
Joan Sola, Adria Gomez-Valent, Javier de Cruz Perez +1
We analyze Brans-Dicke gravity with a cosmological constant, , and cold dark matter (BD-CDM for short) in the light of the latest cosmological observations on distant superno…
Quasar X-ray and UV flux, baryon acoustic oscillation, and Hubble parameter measurement constraints on cosmological model parameters
Narayan Khadka, Bharat Ratra
We use the Risaliti & Lusso (2015) compilation of 808 X-ray and UV flux measurements of quasars (QSOs) in the redshift range , alone and in conjuction with…
Using SPTpol, Planck 2015, and non-CMB data to constrain tilted spatially-flat and untilted non-flat CDM, XCDM, and CDM dark energy inflation cosmologies
Chan-Gyung Park, Bharat Ratra
We use six tilted spatially-flat and untilted non-flat dark energy cosmological models in analyses of South Pole Telescope polarization (SPTpol) cosmic microwave background (CMB) d…
Proper Fourier decomposition formalism for cosmological fields in spherical shells
Lado Samushia
Cosmological random fields are often analysed in spherical Fourier-Bessel basis. Compared to the Cartesian Fourier basis this has an advantage of properly taking into account some…
Computing 3 point correlation function randoms counts without the randoms catalogue
David W. Pearson, Lado Samushia
As we move towards future galaxy surveys, the three-point statistics will be increasingly leveraged to enhance the constraining power of the data on cosmological parameters. An ess…
A model independent constraint on the temporal evolution of the speed of light
Dandan Wang, Hanyu Zhang, Jinglan Zheng +2
We present a new, model-independent method to reconstruct the temporal evolution of the speed of light using astronomical observations. After validating our pipeline using m…
Baryon acoustic oscillation, Hubble parameter, and angular size measurement constraints on the Hubble constant, dark energy dynamics, and spatial curvature
Joseph Ryan, Yun Chen, Bharat Ratra
In this paper we use all available baryon acoustic oscillation, Hubble parameter, and quasar angular size data to constrain six dark energy cosmological models, both spatially flat…
First study of reionization in tilted flat and untilted non-flat dynamical dark energy inflation models
Sourav Mitra, Chan-Gyung Park, Tirthankar Roy Choudhury +1
We examine the effects of dark energy dynamics and spatial curvature on cosmic reionization by studying reionization in tilted spatially-flat and untilted non-flat XCDM and CDM…
Cosmological magnetic braking and the formation of high-redshift, super-massive black holes
Kanhaiya L. Pandey, Shiv K. Sethi, Bharat Ratra
We study the effect of magnetic braking due to a primordial magnetic field in the context of the formation of massive () direct collapse black holes (DCBHs)…
