A linear relation between galaxy-lensing cross-correlations to test the cosmological principle model-independently
Hai Yu, Pengjie Zhang, Jiaxin Wang +2
We discover a linear relation between two sets of galaxy-lensing cross-correlations. This linear relation holds, as long as light follows the geodesic and the metric is Friedmann-L…
A New Method to Measure Hubble Parameter using Fast Radio Bursts
Q. Wu, Hai Yu, F. Y. Wang
The Hubble parameter is directly related to the expansion of our Universe. It can be used to study dark energy and constrain cosmology models. In this paper, we propose that…
Dark matter deficient galaxies in the Illustris flat-CDM model structure formation simulation
Hai Yu, Bharat Ratra, Fa-Yin Wang
Surveying dark matter deficient galaxies (those with dark matter mass to stellar mass ratio ) in the Illustris simulation of structure formation in the f…
Measuring the cosmic proper distance from fast radio bursts
H. Yu, F. Y. Wang
The cosmic proper distance is a fundamental distance in the Universe. Unlike the luminosity and angular diameter distances, which correspond to the angular size, the proper d…
The Age-Redshift Relationship of Old Passive Galaxies
Jun-Jie Wei, Xue-Feng Wu, Fulvio Melia +2
We use 32 age measurements of passively evolving galaxies as a function of redshift to test and compare the standard model (CDM) with the Universe. We show that t…
