Do reverberation-measured H quasars provide a useful test of cosmology?
Narayan Khadka, Mary Loli Martínez-Aldama, Michal Zajaček +2
We use 118 H quasar (QSO) observations in the redshift range to simultaneously constrain cosmological model parameters and QSO 2-parameter radius-lumin…
Standardizing Dainotti-correlated gamma-ray bursts, and using them with standardized Amati-correlated gamma-ray bursts to constrain cosmological model parameters
Shulei Cao, Narayan Khadka, Bharat Ratra
We show that each of the three Dainotti-correlated gamma-ray burst (GRB) data sets recently compiled by Wang et al. and Hu et al., that together probe the redshift range $0.35 \leq…
Do quasar X-ray and UV flux measurements provide a useful test of cosmological models?
Narayan Khadka, Bharat Ratra
The recent compilation of quasar (QSO) X-ray and UV flux measurements include QSOs that appear to not be standardizable via the X-ray luminosity and UV luminosity () re…
Standardizing reverberation-measured Mg II time-lag quasars, by using the radius-luminosity relation, and constraining cosmological model parameters
Narayan Khadka, Zhefu Yu, Michal Zajaček +3
We use 78 reverberation-measured Mg II time-lag quasars (QSOs) in the redshift range to constrain cosmological parameters in six different cosmological mo…
Do gamma-ray burst measurements provide a useful test of cosmological models?
Narayan Khadka, Orlando Luongo, Marco Muccino +1
We study eight different gamma-ray burst (GRB) data sets to examine whether current GRB measurements -- that probe a largely unexplored part of cosmological redshift () space --…
