Is Dark Matter Really Matter?
Jun-Qian Jiang, Arman Shafieloo
In the standard model of cosmology, it is assumed that dark matter is pressureless with equation of state and dark energy has . We test these assumptions jointly using…
A fast deep-learning approach to probing primordial black hole populations in gravitational wave events
Jun-Qian Jiang, Hai-Long Huang, Jibin He +2
Primordial black holes (PBHs), envisioned as a compelling dark matter candidate and a window onto early-Universe physics, may contribute to some of the gravitational-wave (GW) sign…
Late-Time Oscillating Quintessence in Light of DESI
Jun-Qian Jiang, Mustafa A. Amin, Arman Shafieloo
Recent DESI baryon acoustic oscillation measurements, especially when combined with Type Ia supernova and CMB data, sharpen the case for possible low-redshift dynamics in the dark…
DeepInflation: an AI agent for research and model discovery of inflation
Ze-Yu Peng, Hao-Shi Yuan, Qi Lai +4
We present DeepInflation, an AI agent designed for research and model discovery in inflationary cosmology. Built upon a multi-agent architecture, DeepInflation integrates Large Lan…
Search for primordial black holes from gravitational wave populations using deep learning
Hai-Long Huang, Zhan-He Wang, Qing-Yu Lan +5
Gravitational waves (GWs) signals detected by the LIGO/Virgo/KAGRA collaboration might be sourced (partly) by the merges of primordial black holes (PBHs). The conventional hierarch…
Measuring neutrino masses with joint JWST and DESI DR2 data
Sheng-Han Zhou, Tian-Nuo Li, Guo-Hong Du +3
Early JWST observations reveal an unexpectedly abundant population of high-redshift candidate massive galaxies at , and recent DESI measurements show a preference for…
