Testing the speed of light over cosmological distances: the combination of strongly lensed and unlensed supernova Ia
Shuo Cao, Jingzhao Qi, Marek Biesiada +3
Probing the speed of light is as an important test of General Relativity but the measurements of using objects in the distant universe have been almost completely unexplored. I…
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…
Anomalies in Time Delays of Lensed Gravitational Waves and Dark Matter Substructures
Kai Liao, Xuheng Ding, Marek Biesiada +2
The cold dark matter scenario of hierarchical large-scale structure formation predicts the existence of abundant subhalos around large galaxies. However, the number of observed dwa…
Model-independent Test of the Cosmic Distance Duality Relation
Cheng-Zong Ruan, Fulvio Melia, Tong-Jie Zhang
A validation of the cosmic distance duality (CDD) relation, eta(z)=(1+z)^2 d_A(z)/d_L(z)=1, coupling the luminosity (d_L) and angular-diameter (d_A) distances, is crucial because i…
Spatial Distribution of Metals in the ICM: Evolution of the Iron Excess in Relaxed Galaxy Clusters
Ang Liu, Paolo Tozzi, Heng Yu +2
We investigate the spatial distribution of iron in the intra-cluster medium in a selected sample of 41 relaxed clusters in the redshift range using {\sl Chandra}…
The Quest for the Inflationary Spectral Runnings in the Presence of Systematic Errors
Xiaolei Li, Noah Weaverdyck, Saroj Adhikari +3
Cosmological inflation predicts that the scalar spectral index "runs" with scale. Constraints on the values of the spectral runnings, and…
Cosmology with Gravitational Wave/Fast Radio Burst Associations
Jun-Jie Wei, Xue-Feng Wu, He Gao
Recently, some theoretical models predicted that a small fraction of fast radio bursts (FRBs) could be associated with gravitational waves (GWs). In this work, we discuss the possi…
Cosmological Model Independent Time Delay Method
Yi Zhang, Xuewen Liu, Jingzhao Qi +1
We propose a Cosmological Model Independent Time Delay (CMITD) method where the Lorentz invariance violation (LIV) variable is constructed by observational data instead of c…
Statistical analysis with cosmic-expansion-rate measurements and two-point diagnostics
Xiaogang Zheng, Marek Biesiada, Xuheng Ding +3
Direct measurements of Hubble parameters are very useful for cosmological model parameters inference. Based on them, Sahni, Shafieloo and Starobinski introduced a two-point…
What is parameterized diagnostics telling us in light of recent observations?
Jing-Zhao Qi, Shuo Cao, Marek Biesiada +4
In this paper, we propose a new parametrization of diagnostics and show how the most recent and significantly improved observations concerning the and SN Ia measurem…
The distance sum rule from strong lensing systems and quasars - test of cosmic curvature and beyond
Jing-Zhao Qi, Shuo Cao, Sixuan Zhang +3
Testing the distance-sum-rule in strong lensing systems provides an interesting method to determine the curvature parameter using more local objects. In this paper, we apply…
Strongly gravitational lensed SNe Ia as multi-messengers: Direct test of the Friedmann-Lema\^ıtre-Robertson-Walker metric
Jing-Zhao Qi, Shou Cao, Marek Biesiada +3
We present a new idea of testing the validity of the Friedman-Lema\^ıtre-Robertson-Walker metric, through the multiple measurements of galactic-scale strong gravitational lensing s…
Co-evolution of supermassive black holes with galaxies from semi-analytic model: stochastic gravitational wave background and black hole clustering
Qing Yang, Bin Hu, Xiao-Dong Li
We study the co-evolution of supermassive black holes (SMBHs) with galaxies by means of semi-analytic model (SAM) of galaxy formation based on sub-halo merger trees built from Mill…
Curvature from strong gravitational lensing: a spatially closed Universe or systematics?
Zhengxiang Li, Xuheng Ding, Guo-Jian Wang +2
Model-independent constraints on the spatial curvature are not only closely related to important problems such as the evolution of the Universe and properties of dark energy, but a…
Cosmological inference from standard sirens without redshift measurements
Xuheng Ding, Marek Biesiada, Xiaogang Zheng +3
The purpose of this work is to investigate the prospects of using the future standard siren data without redshift measurements to constrain cosmological parameters. With successful…
