Revisiting dark energy models using differential ages of galaxies
Nisha Rani, Deepak Jain, Shobhit Mahajan +2
In this work, we use a test based on the differential ages of galaxies for distinguishing the dark energy models. As proposed by Jimenez and Loeb, relative ages of galaxies can be…
Measuring the speed of light with ultra-compact radio quasars
Shuo Cao, Marek Biesiada, John Jackson +3
In this paper, based on a 2.29 GHz VLBI all-sky survey of 613 milliarcsecond ultra-compact radio sources with , we describe a method of identifying the sub-sample w…
What are and diagnostics telling us in light of data?
Xiaogang Zheng, Xuheng Ding, Marek Biesiada +2
Two-point diagnostics and have been introduced as an interesting tool for testing the validity of the CDM model. Quite recently, Sahni, Shafieloo…
Limits on the power-law mass and luminosity density profiles of elliptical galaxies from gravitational lensing systems
Shuo Cao, Marek Biesiada, Meng Yao +1
We use 118 strong gravitational lenses observed by the SLACS, BELLS, LSD and SL2S surveys to constrain the total mass profile and the profile of luminosity density of stars (light-…
Constraints on non-flat cosmologies with massive neutrinos after Planck 2015
Yun Chen, Bharat Ratra, Marek Biesiada +2
We investigate two dark energy cosmological models (i.e., the CDM and CDM models) with massive neutrinos assuming two different neutrino mass hierarchies in both the spatiall…
Testing the gas mass density profile of galaxy clusters with distance duality relation
Shuo Cao, Marek Biesiada, Xiaogang Zheng +1
In this paper, assuming the validity of distance duality relation, , where and are the angular and the luminosity distance respective…
