Test of the cosmic distance duality relation for arbitrary spatial curvature
Jin Qin, Fulvio Melia, Tong-Jie Zhang
The cosmic distance duality relation (CDDR), eta(z)=(1+z)^2 d_A(z)/d_L(z)=1, is one of the most fundamental and crucial formulae in cosmology. This relation couples the luminosity…

Assessing Cosmic Acceleration with the Alcock-Paczynski Effect in the SDSS-IV Quasar Catalog
Fulvio Melia, Jin Qin, Tong-Jie Zhang
The geometry of the Universe may be probed using the Alcock-Paczynski (AP) effect, in which the observed redshift size of a spherical distribution of sources relative to its angula…
