Gravitational-Wave Detector Networks: Standard Sirens on Cosmology and Modified Gravity Theory
Tao Yang
We construct the catalogues of standard sirens (StS) based on the future gravitational wave (GW) detector networks, i.e., the second-generation ground-based advanced LIGO+advanced…
Running Hubble Tension and a H0 Diagnostic
Chethan Krishnan, Eoin Ó Colgáin, M. M. Sheikh-Jabbari +1
Hubble tension is routinely presented as a mismatch between the Hubble constant determined locally and a value inferred from the flat CDM cosmology. In essence, the tensio…
Model-Independent Perspectives on Coupled Dark Energy and the Swampland
Tao Yang
We present a general model-independent approach to study the coupled dark energy and the string Swampland criteria. We show how the dark sector interaction is degenerated with the…
Hubble Sinks In The Low-Redshift Swampland
Aritra Banerjee, Haiying Cai, Lavinia Heisenberg +3
Local determinations of the Hubble constant favour a higher value than Planck based on CMB and CDM. Through a model-independent expansion, we show that low redshift ($z \l…
The first simultaneous measurement of Hubble constant and post-Newtonian parameter from Time-Delay Strong Lensing
Tao Yang, Simon Birrer, Bin Hu
Strong gravitational lensing has been a powerful probe of cosmological models and gravity. To date, constraints in either domain have been obtained separately. We propose a new met…
Is there an early Universe solution to Hubble tension?
Chethan Krishnan, Eoin Ó Colgáin, Ruchika +3
We consider a low redshift cosmological dataset comprising megamasers, cosmic chronometers, type Ia SNe and BAO, which we bin according to their redshift. For each bin, w…
Gaussian processes reconstruction of modified gravitational wave propagation
Enis Belgacem, Stefano Foffa, Michele Maggiore +1
Recent work has shown that modified gravitational wave (GW) propagation can be a powerful probe of dark energy and modified gravity, specific to GW observations. We use the techniq…
Cosmography and flat CDM tensions at high redshift
Tao Yang, Aritra Banerjee, Eoin Ó Colgáin
Risaliti, Lusso \& collaborators have constructed a high-redshift Hubble diagram of supernovae (SNe); quasars (QSO) and gamma-ray bursts (GRB) that shows a " tension w…
New probe of gravity: strongly lensed gravitational wave multi-messenger approach
Tao Yang, Bin Hu, Rong-Gen Cai +1
Strong gravitational lensing by galaxies provides us with a unique opportunity to understand the nature of gravity on galactic and extra-galactic scales. In this paper, we propose…
Super-Eddington accreting massive black holes explore high- cosmology: Monte-Carlo simulations
Rong-Gen Cai, Zong-Kuan Guo, Qing-Guo Huang +1
In this paper, we simulate Super-Eddington accreting massive black holes (SEAMBHs) as the candles to probe cosmology for the first time. SEAMBHs have been demonstrated to be able t…
Probing cosmic anisotropy with gravitational waves as standard sirens
Rong-Gen Cai, Tong-Bo Liu, Xue-Wen Liu +2
The gravitational wave (GW) as a standard siren directly determines the luminosity distance from the gravitational waveform without reference to the specific cosmological model, of…
Constraints on the cosmic distance duality relation with simulated data of gravitational waves from the Einstein Telescope
Tao Yang, R. F. L. Holanda, Bin Hu
The cosmic distance duality relation (CDDR) has been test through several astronomical observations in the last years. This relation establishes a simple equation relating the angu…
Standard sirens and dark sector with Gaussian process
Rong-Gen Cai, Tao Yang
The gravitational waves from compact binary systems are viewed as a standard siren to probe the evolution of the universe. This paper summarizes the potential and ability to use th…
Null test of the cosmic curvature using and supernovae data
Rong-Gen Cai, Zong-Kuan Guo, Tao Yang
We introduce a model-independent approach to the null test of the cosmic curvature which is geometrically related to the Hubble parameter and luminosity distance . C…
Reconstructing the interaction between dark energy and dark matter using Gaussian Processes
Tao Yang, Zong-Kuan Guo, Rong-Gen Cai
We present a nonparametric approach to reconstruct the interaction between dark energy and dark matter directly from SNIa Union 2.1 data using Gaussian processes, which is a fully…
