Finding the distribution of matter using lenses - II: deconvolution-based reconstruction with 3x2pt measurements
Jun-Qian Jiang, Ajoy Dawn, Dhiraj Kumar Hazra +2
We present a deconvolution-based framework for testing scale-dependent departures of the late-time matter power spectrum from a fiducial cosmological model using pt measu…
Finding the distribution of matter using lenses - I: deconvolution-based reconstruction with CMB lensing
Ajoy Dawn, Jun-Qian Jiang, Dhiraj Kumar Hazra +2
The matter power spectrum is one of the primary statistical descriptors of the large-scale distribution of matter in the Universe and provides a powerful probe of cosmic structure…
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…
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…
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…
