Accretion disks, quasars and cosmology: meandering towards understanding
Bozena Czerny, Shulei Cao, Vikram Kumar Jaiswal +11
As Setti & Woltjer noted back in 1973, quasars could be used to construct the Hubble diagram but the actual application was not that straightforward. It took years to implement the…
Standardizing reverberation-measured C IV time-lag quasars, and using them with standardized Mg II quasars to constrain cosmological parameters
Shulei Cao, Michal Zajaček, Swayamtrupta Panda +3
We use 38 C IV quasar (QSO) reverberation-mapped (RM) observations, which span eight orders of magnitude in luminosity and the redshift range , to simul…
Using lower-redshift, non-CMB, data to constrain the Hubble constant and other cosmological parameters
Shulei Cao, Bharat Ratra
We use updated Hubble parameter and baryon acoustic oscillation data, as well as other lower-redshift Type Ia supernova, Mg II reverberation-measured quasar, quasar angular size, H…
Gamma-ray burst data strongly favor the three-parameter fundamental plane (Dainotti) correlation relation over the two-parameter one
Shulei Cao, Maria Dainotti, Bharat Ratra
Gamma-ray bursts (GRBs), observed to redshift , are potential probes of the largely unexplored part of the early Universe. Thus, finding relevant relations a…
Potentialities of Hubble parameter and expansion rate function data to alleviate Hubble tension
Yingjie Yang, Xuchen Lu, Lei Qian +1
Taking advantage of Gaussian process (GP), we obtain an improved estimate of the Hubble constant, km s Mpc, using Hubble parameter [] from co…
Standardizing Platinum Dainotti-correlated gamma-ray bursts, and using them with standardized Amati-correlated gamma-ray bursts to constrain cosmological model parameters
Shulei Cao, Maria Dainotti, Bharat Ratra
We show that the Platinum gamma-ray burst (GRB) data compilation, probing the redshift range , obeys a cosmological-model-independent three-parameter fundame…
