AI-assisted super-resolution cosmological simulations II: Halo substructures, velocities and higher order statistics
In this work, we expand and test the capabilities of our recently developed super-resolution (SR) model to generate high-resolution (HR) realizations of the full phase-space matter distribution, including both displacement and velocity, from computationally cheap low-resolution (LR) cosmological N-body simulations.
AI-assisted super-resolution cosmological simulations
Cosmological simulations of galaxy formation are limited by finite computational resources.
Trend Filtering -- II. Denoising Astronomical Signals with Varying Degrees of Smoothness
The remaining studies share broad themes of: (1) estimating observable parameters of light curves and spectra; and (2) constructing observational spectral/light-curve templates.

Trend Filtering: A Modern Statistical Tool for Time-Domain Astronomy and Astronomical Spectroscopy
The problem of denoising a one-dimensional signal possessing varying degrees of smoothness is ubiquitous in time-domain astronomy and astronomical spectroscopy.

Towards Machine-assisted Meta-Studies: The Hubble Constant
We present an approach for automatic extraction of measured values from the astrophysical literature, using the Hubble constant for our pilot study.
The one-dimensional Ly-alpha forest power spectrum from BOSS
We have developed two independent methods to measure the one-dimensional power spectrum of the transmitted flux in the Lyman-$\alpha$ forest.
