Late-time cosmological constraints on three holographic dark energy models with DESI DR2 BAO and Type Ia supernovae
Jiayuan Huang, Tonghua Liu, Chenggang Shao
We constrain three holographic-inspired dark energy models, namely holographic dark energy (HDE), agegraphic dark energy (ADE), and Ricci dark energy (RDE), using late-time observa…
Extragalactic test of General Relativity with time-delay gravitational lenses
Wuzheng Guo, Shuo Cao, Qiumin Wang +4
Strong gravitational lensing, a key prediction of General Relativity (GR), offers a unique environment for examining alternative modified gravity theories. In this Letter, we emplo…
Identification of Lensed Gravitational-Wave Beat Patterns by LISA
Hengyu Wu, Tonghua Liu, Kai Liao
Strong lensing of massive black hole binaries can produce multiple gravitational-wave images with different magnifications and arrival times. LISA signals remain in band for months…
Mock Catalogs of Strongly Lensed Gravitational Waves via a Halo Model Approach with Space-borne Detectors
Mingqi Sun, Kai Liao, Youkai Li +6
Future space-borne gravitational-wave (GW) detectors, such as LISA and DECIGO, are expected to detect a large number of GW events, a fraction of which may be strongly lensed by int…
Metastability in Emergent Dark Energy: A New Framework Confronting Cosmological Observations
Xiaolei Li, Tonghua Liu, Tian-Nuo Li +3
We propose the Metastable Emergent Dark Energy (MEDE) model, a novel phenomenological extension of the Phenomenological (PEDE) and Generalized (GEDE) Emergent Dark Energy framework…
Polarization Birefringence and Waveform Systematics in GW231123
Tonghua Liu, Chenggang Shao, Kai Liao
GW231123 is a short, massive binary-black-hole event whose source properties show strong waveform dependence. We use this event to test gravitational-wave polarization birefringenc…
Testing General Relativity on Galactic Scales via DESI-BAO and Strong Lensing: Circumventing Assumptions on the Hubble Constant, Sound Horizon, and Dark Energy
Hengyu Wu, Tonghua Liu, Chenggang Shao
We present a cosmological model-independent framework for testing general relativity (GR) on galactic scales by combining baryon acoustic oscillation (BAO) angular scale measuremen…
Model-Independent Reconstruction of Quintessence Potential and Kinetic Energy from DESI DR2 and Pantheon+ Supernovae
Shengjia Wang, Tian-Nuo Li, Tonghua Liu +1
We present a model-independent reconstruction of the quintessence scalar field's dynamics-both its potential and kinetic energy-directly from the latest cosmological observations.…
Exploring the central engines of gamma-ray bursts from prompt light curves
Xue Zhang, Shuang-Xi Yi, Wei-Hua Lei +6
Hyperaccreting stellar-mass black hole systems are leading candidates for the central engines of gamma-ray bursts (GRBs). Their jets are thought to be powered by either the Blandfo…
Evidence for deviation in gravitational light deflection from general relativity at cosmological scales with KiDS-Legacy and CMB lensing
Guo-Hong Du, Tian-Nuo Li, Tonghua Liu +2
General relativity (GR) faces challenges from cosmic acceleration and observational tensions, necessitating stringent tests at cosmological scales. In this work, we probe GR deviat…
Improved Identification of Strongly Lensed Gravitational Waves with Host Galaxy Locations
Tonghua Liu, Kai Liao
We present a Bayesian framework that enhances the identification of strongly lensed gravitational waves (GWs) by incorporating informative positional priors from the Euclid galaxy…
CSST Strong Lensing Preparation: Cosmological Constraints Forecast from CSST Galaxy-Scale Strong Lensing
