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…
