Low- and high-redshift H II starburst galaxies obey different luminosity-velocity dispersion relations

Shulei Cao, Bharat Ratra

To determine whether or not H II starburst galaxies (H IIG) are standardizable candles, we study the correlation between the H $β$ luminosity ( $L$ ) and the velocity dispersion ( $σ$ )…

Effects of heterogeneous data sets and time-lag measurement techniques on cosmological parameter constraints from MgII and CIV reverberation-mapped quasar data

Shulei Cao, Michal Zajaček, Bożena Czerny +2

Previously, we demonstrated that MgII and CIV reverberation-mapped quasars (RM QSOs) are standardizable and that the cosmological parameters inferred using the broad-line region ra…

$H_{0} = 69.8 \pm 1.3$ $km s^{- 1} Mp c^{- 1}$ , $Ω_{m 0} = 0.288 \pm 0.017$ , and other constraints from lower-redshift, non-CMB, expansion-rate data

Shulei Cao, Bharat Ratra

We use updated Type Ia Pantheon+ supernova, baryon acoustic oscillation, and Hubble parameter (now also accounting for correlations) data, as well as new reverberation-measured C I…
