Cosmological constraints from HII starburst galaxy apparent magnitude and other cosmological measurements
Shulei Cao, Joseph Ryan, Bharat Ratra
We use HII starburst galaxy apparent magnitude measurements to constrain cosmological parameters in six cosmological models. A joint analysis of HII galaxy, quasar angular size, ba…

Evidence against Ryskin's model of cosmic acceleration
Joseph Ryan
In this paper I examine how well Ryskin's model of emergent cosmic acceleration fits several sets of cosmological observations. I find that while Ryskin's model is somewhat compati…

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…
