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…
Speed of Gravitational Waves from Strongly Lensed Gravitational Waves and Electromagnetic Signals
Xi-Long Fan, Kai Liao, Marek Biesiada +2
We propose a new model-independent measurement strategy for the propagation speed of gravitational waves (GWs) based on strongly lensed GWs and their electromagnetic (EM) counterpa…
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…
Exploring Cosmic Origins with CORE: Extragalactic sources in Cosmic Microwave Background maps
G. De Zotti, J. Gonzalez-Nuevo, M. Lopez-Caniego +121
We discuss the potential of a next generation space-borne Cosmic Microwave Background (CMB) experiment for studies of extragalactic sources. Our analysis has particular bearing on…
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-…
