Predicting the long-term stability of compact multiplanet systems
Our Stability of Planetary Orbital Configurations Klassifier (SPOCK) predicts stability using physically motivated summary statistics measured in integrations of the first $10^4$ orbits, thus achieving speed-ups of up to $10^5$ over full simulations.

Removing Astrophysics in 21 cm maps with Neural Networks
• georgestein/ml-in-cosmology
• 
From these simulations we produce tens of thousands of 21 cm maps at redshifts $10\leq z\leq 20$.

The Cosmic Linear Anisotropy Solving System (CLASS) II: Approximation schemes
Boltzmann codes are used extensively by several groups for constraining cosmological parameters with Cosmic Microwave Background and Large Scale Structure data.
COSMOLOGY AND NONGALACTIC ASTROPHYSICS
The impact of spectroscopic incompleteness in direct calibration of redshift distributions for weak lensing surveys
We do so by simulating the process of assembling a spectroscopic sample (including observer-assigned confidence flags) and highlight the impacts of spectroscopic target selection and redshift failures.

$\mathit{Chempy}$: A flexible chemical evolution model for abundance fitting - Do the Sun's abundances alone constrain chemical evolution models?
A Chempy model is specified by a set of 5-10 parameters that describe the effective galaxy evolution along with the stellar and star-formation physics: e. g. the star-formation history, the feedback efficiency, the stellar initial mass function (IMF) and the incidence of supernova type Ia (SN Ia).

Low-scatter galaxy cluster mass proxies for the eROSITA all-sky survey
The on-going X-ray all-sky survey with the eROSITA instrument will yield large galaxy cluster samples, which will bring strong constraints on cosmological parameters.

JAXNS: a high-performance nested sampling package based on JAX
Since its debut by John Skilling in 2004, nested sampling has proven a valuable tool to the scientist, providing hypothesis evidence calculations and parameter inference for complicated posterior distributions, particularly in the field of astronomy.
