A Robust Geometric Distortion Solution for Main Survey Camera of CSST
Yibo Yan, You Wu, Jundan Nie +30
The advancement in sensitivity and field of view of next-generation wide-field survey telescopes requires astrometric measurements with high precision, even in the presence of sign…
Observational challenges to holographic and Ricci dark energy paradigms: Insights from ACT DR6 and DESI DR2
Peng-Ju Wu, Tian-Nuo Li, Guo-Hong Du +1
Recent studies suggest that dark energy may be dynamical rather than being a mere cosmological constant . In this work, we examine the viability of two physically well-motivate…
Prospects for searching for sterile neutrinos in dynamical dark energy cosmologies using joint observations of gravitational waves and -ray bursts
Lu Feng, Tao Han, Jing-Fei Zhang +1
In the era of third-generation (3G) gravitational-wave (GW) detectors, GW standard siren observations from binary neutron star mergers provide a powerful tool for probing the expan…
Prospects for probing dark matter particles and primordial black holes with the Square Kilometre Array using the 21 cm power spectrum at cosmic dawn
Meng-Lin Zhao, Yue Shao, Sai Wang +1
Probing the nature of dark matter (DM) remains an outstanding problem in modern cosmology. The 21 cm signal, as a sensitive tracer of neutral hydrogen during cosmic dawn, provides…
Characterized behaviors of black hole thermodynamics in the supercritical region
Zi-Qiang Zhao, Zhang-Yu Nie, Jing-Fei Zhang +1
The comprehension of universal thermodynamic behaviors in the supercritical region is crucial for examining the characteristics of black hole systems under high temperature and pre…
Configuration Requirements for 21-cm Forest Background Quasar Searches with the Moon-based Interferometer
Siyuan Zhang, Qi Niu, Yichao Li +1
The 21-cm forest offers a powerful cosmological probe of the thermal history and small-scale structure of the intergalactic medium during the Epoch of Reionization (EoR). Its succe…
