Cosmological Distance Measurement of Twelve Nearby Supernovae IIP with ROTSE-IIIb
Published 2024-01-01“…We then perform cosmological parameter fitting using these EPM distances, from which we measure the Hubble constant to be ${72.9}_{-4.3}^{+5.7}\,\mathrm{km}\,{{\rm{s}}}^{-1}\,{\mathrm{Mpc}}^{-1}$ , which is consistent with the standard ΛCDM model values derived using other independent techniques.…”

Solar System-scale Interferometry on Fast Radio Bursts Could Measure Cosmic Distances with Subpercent Precision
Published 2023-01-01“…If the spacetime positions of the detectors are known to a few centimeters, comparable to the accuracy to which very long baseline interferometry baselines and global navigation satellite systems (GNSS) geolocations are constrained, nanosecond timing would allow competitive cosmological constraints. We show that a four-detector constellation at Solar radii of ≳10 au could measure geometric distances to individual sources with subpercent precision. …”

Extreme Quasars as Distance Indicators in Cosmology
Published 2020-01-01“…As a result of the small scatter in Eddington ratio shown by xA quasars, we propose a method to derive the main cosmological parameters based on redshift-independent “virial luminosity” estimates from measurements of emission line widths, roughly equivalent to the luminosity estimates based from line width in early and late type galaxies. …”
