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…
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…
Single field slow-roll inflation with step uplift to
Hao-Shi Yuan, Ze-Yu Peng, Yun-Song Piao
The early dark energy resolution of Hubble tension seems to be suggesting a scale-invariant Harrison-Zeldovich spectrum of primordial scalar perturbation, i.e. ($|n_s-1|\si…
The environmental dependence of mid-IR luminous dusty Supernovae
Lin Xiao, Zeyue Peng, Lluis Galbany +10
Using the Spitzer and WISE images, we discovered 42 mid-IR luminous dusty supernovae with local integral-field spectroscopy data. The observed mid-IR emission indicates the presenc…
Testing in light of the latest ACT and SPT data
Ze-Yu Peng, Jun-Qian Jiang, Hao Wang +1
It is commonly recognized that the primordial scalar spectral index is approximately , depending on the dataset. However, this view is being completely altered by…
Hint of after DESI DR2 ?
Hao Wang, Ze-Yu Peng, Yun-Song Piao
In the report by BICEP/Keck collaborations, the tensor-to-scalar ratio is (95\% C.L.). However, recent datasets have preferred the evolving dark energy, which thus…
