unyt: Handle, manipulate, and convert data with units in Python

Software that processes real-world data or that models a physical system must have some way of managing units. While simple approaches like the understood convention that all data are in a unit system (such as the MKS SI unit system) do work in …

Machine learning and cosmological simulations -- I. Semi-analytical models

We present a new exploratory framework to model galaxy formation and evolution in a hierarchical Universe by using machine learning (ML). Our motivations are two-fold: (1) presenting a new, promising technique to study galaxy formation, and (2) …

Machine learning and cosmological simulations--II. Hydrodynamical simulations

We extend a machine learning (ML) framework presented previously to model galaxy formation and evolution in a hierarchical universe using N-body+ hydrodynamical simulations. In this work, we show that ML is a promising technique to study galaxy …

Vertical Integration

Gmail. It serves as the center of my digital life. When I receive a new email with a Google Docs document linked in it, there's a preview of that document--- when I send one to someone else, Gmail first checks to see if the person receiving it has …

Dark Sky Simulations: Early Data Release

The Dark Sky Simulations are an ongoing series of cosmological N-body simulations designed to provide a quantitative and accessible model of the evolution of the large-scale Universe. Such models are essential for many aspects of the study of dark …

Fostering Collaborative Computational Science

Designing Software for Collaboration In computational science, collaboration in different scientific communities often takes different forms---examining the results of data generation or acquisition, combining dispa- rate pieces of software in a …

Seismic Sound Lab: Sights, Sounds and Perception of the Earth as an Acoustic Space

We construct a representation of earthquakes and global seismic waves through sound and animated images. The seismic wave field is the ensemble of elastic waves that propagate through the planet after an earthquake, emanating from the rupture on the …

The Ground beath our Feet: Earth Science in the Planetarium

What topics belong inside a planetarium and what is beyond the scope of our mission? Are we limited to astronomy?

DWARF GALAXIES WITH IONIZING RADIATION FEEDBACK. II. SPATIALLY RESOLVED STAR FORMATION RELATION

We investigate the spatially resolved star formation relation using a galactic disk formed in a comprehensive high-resolution (3.8 pc) simulation. Our new implementation of stellar feedback includes ionizing radiation as well as supernova explosions, …

DWARF GALAXIES WITH IONIZING RADIATION FEEDBACK. I. ESCAPE OF IONIZING PHOTONS

We describe a new method for simulating ionizing radiation and supernova feedback in the analogs of low-redshift galactic disks. In this method, which we call star-forming molecular cloud (SFMC) particles, we use a ray-tracing technique to solve the …
