Imprint of swampland-inspired coupled early dark energy
Hao Wang, Yun-Song Piao
Inspired by the Swampland Distance Conjecture, we investigate the cosmological implications of a fractional coupling between dark matter (DM) and early dark energy (EDE) in light o…
Inverse-k Primordial Oscillations from a Symbolic Regression Search
Ze-Yu Peng, Qing-Yu Lan, Yun-Song Piao
Oscillatory features in the primordial power spectrum, potential signatures of new physics in the early universe, are usually searched for using fixed templates. In this work, we p…
Constraining supermassive primordial black hole clustering with the angular auto-correlation of quasars
Zhan-He Wang, Hai-Long Huang, Yun-Song Piao
High-redshift quasars provide a direct probe of the origin and environment of the earliest supermassive black holes. We use their angular auto-correlation function at t…
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…
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…
