HIcosmo: a differentiable JAX-based framework for cosmology inference
Jing-Zhao Qi, Jing-Fei Zhang, Xin Zhang
The Stage IV cosmological surveys, such as Euclid, LSST, DESI, and SKA, will deliver observational data of unprecedented volume, calling for efficient and reliable inference tools.…
Gravitational wave standard sirens from GWTC-3 combined with DESI DR2 and DESY5: A late-universe probe of the Hubble constant and dark energy
Ji-Yu Song, Guo-Hong Du, Tian-Nuo Li +4
Recently, the combination of the Dark Energy Spectroscopic Instrument (DESI) Data Release 2 (DR2) baryon acoustic oscillation (BAO) data and the Planck cosmic microwave background…
Testing the cosmic distance duality relation with baryon acoustic oscillations and supernovae data
Tian-Nuo Li, Guo-Hong Du, Peng-Ju Wu +3
One of the most fundamental relationships in modern cosmology is the cosmic distance duality relation (CDDR), which describes the relationship between the angular diameter distance…
Model-independent within FLRW: Joint constraints from GWTC-3 standard sirens and strong lensing time delays
Ji-Yu Song, Jing-Zhao Qi, Jing-Fei Zhang +1
We use 47 gravitational-wave (GW) standard sirens from the third Gravitational-Wave Transient Catalog to calibrate distances in the strong gravitational lensing (SGL) system RXJ113…
Combining strongly lensed and unlensed fast radio bursts: To be a more precise late-universe probe
Ji-Guo Zhang, Yi-Fan Jiang, Ze-Wei Zhao +3
The Macquart relation and time-delay cosmography are now two promising ways to fast radio burst (FRB) cosmology. In this work, we propose a joint method that combines strongly lens…
Joint observations of late universe probes: cosmological parameter constraints from gravitational wave and Type Ia supernova data
Jie Zheng, Xiao-Hui Liu, Jing-Zhao Qi
The growing tensions between the early Universe and the late Universe increasingly highlight the importance of developing precise probes for late cosmology. As significant late-Uni…
Testing the Cosmic Distance Duality Relation Using Strong Gravitational Lensing Time Delays and Type Ia Supernovae
Jing-Zhao Qi, Yi-Fan Jiang, Wan-Ting Hou +1
We present a comprehensive test of the cosmic distance duality relation (DDR) using a combination of strong gravitational lensing (SGL) time delay measurements and Type Ia supernov…
Model-independent measurement of cosmic curvature with the latest and SNe Ia data: A comprehensive investigation
Jing-Zhao Qi, Ping Meng, Jing-Fei Zhang +1
In the context of the discrepancies between the early and late universe, we emphasize the importance of independent measurements of the cosmic curvature in the late universe. We pr…
Prospects for constraining interacting dark energy models from gravitational wave and gamma ray burst joint observation
Wan-Ting Hou, Jing-Zhao Qi, Tao Han +3
With the measurement of the electromagnetic (EM) counterpart, a gravitational wave (GW) event could be treated as a standard siren. As a novel cosmological probe, GW standard siren…
Null test for cosmic curvature using Gaussian process
Peng-Ju Wu, Jing-Zhao Qi, Xin Zhang
The cosmic curvature , which determines the spatial geometry of the universe, is an important parameter in modern cosmology. Any deviation from would have a pr…
Cosmological Parameter Estimation Using Current and Future Observations of Strong Gravitational Lensing
Jing-Zhao Qi, Wei-Hong Hu, Yu Cui +2
Remarkable development of cosmology is benefited from the increasingly improved measurements of cosmic distances including absolute distances and relative distances. In recent year…
Strongly lensed type Ia supernovae as a precise late-universe probe of measuring the Hubble constant and cosmic curvature
Jing-Zhao Qi, Yu Cui, Wei-Hong Hu +3
Strongly lensed type Ia supernovae (SNe Ia) are expected to have some advantages in measuring time delays of multiple images, and so they have a great potential to be developed int…
Cosmological model-independent measurement of cosmic curvature using distance sum rule with the help of gravitational waves
Yan-Jin Wang, Jing-Zhao Qi, Bo Wang +3
Although the cosmic curvature has been tightly constrained in the standard cosmological model using observations of cosmic microwave background anisotropies, it is still of great i…

Galaxy-Scale Test of General Relativity with Strong Gravitational Lensing
Xiao-Hui Liu, Zhen-Hua Li, Jing-Zhao Qi +1
Although general relativity (GR) has been precisely tested at the solar system scale, precise tests at a galactic or cosmological scale are still relatively insufficient. Here, in…
