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.
EARTH AND PLANETARY ASTROPHYSICS
From these simulations we produce tens of thousands of 21 cm maps at redshifts $10\leq z\leq 20$.
COSMOLOGY AND NONGALACTIC ASTROPHYSICS ASTROPHYSICS OF GALAXIES
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
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.

The Astropy project supports and fosters the development of open-source and openly-developed Python packages that provide commonly-needed functionality to the astronomical community.
INSTRUMENTATION AND METHODS FOR ASTROPHYSICS
The code natively supports initial conditions with nested zoom regions at progressively increasing resolution.

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).

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.

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.

We present the Open Supernova Catalog, an online collection of observations and metadata for presently 36, 000+ supernovae and related candidates.
