This is a movie of three galaxy formation simulations I ran as part of my research.
The color of each pixel represents the temperature of the gas (blue for cold and green for hot) and the brightness of each pixel represents the density (dim for low density bright for high...
Portrait of the Galaxy is a snapshot from a 3d rendering of a galaxy that displays the complex structure of the gas component of the simulation. This gas component is difficult to observe in real telescopes but with visualizations and simulations like these we can begin to understand how to...
Mixing due to cutting-and-shuffling is studied at a fundamental level using 2D mappings known as Piecewise Isometries (PWI) which can create beautiful mixing patterns. The PWI studied here splits a hemispherical shell (HS) into four curved triangular pieces that are rearranged to make a shuffled HS. Applying the PWI repeatedly...
This visualization shows two-photon imaging of GCamp6f in hippocampal pyramidal neurons as a mouse navigates a virtual reality maze. These techniques give us an indirect measure of activity in neurons or small compartments of neurons in an awake, behaving animal. The hippocampus has been well characterized as playing an essential...
These images show how the Facebook networks of 121 LGBTQ youth (Mage = 24.13 years) differ depending on how “out” these young people are about their identities. Using cluster analysis of survey data, we found LGBTQ youth managed outness in one of four ways: high overall outness (63.82%), low overall...
This work introduces a novel optical 3D sensor principle and its implementation: the ‘single-shot 3D movie camera’. The camera is designed for the 3D measurement of macroscopic objects with scattering surfaces, e.g. human faces. It combines the acquisition of a dense point cloud displaying physically limited lateral resolution and depth...
Massive Black Holes, millions to billions of times more massive than our sun, exist in the centers of most galaxies. However, the formation and evolution of these objects through accretion of gas and mergers with other black holes is still a great mystery. LISA, a future space-based gravitational wave detector,...
A fractal is created by a Piecewise Isometry (PWI) which cuts a 2D object into pieces and rearranges those pieces to recreate the original object in a scrambled form. The PWI studied here splits a hemispherical shell into four pieces along cutting lines and rearranges them into a shuffled hemisphere....
Levitation—the rising or hovering of an object in apparent defiance of gravity—is a captivating phenomenon with a wide range of applications. In this visualization, we demonstrate our newly discovered form of fluid dynamical levitation of small particles that may be 10, 100, or even 1000 times as dense as the...
Firefly is an interactive tool that allows users to fly through any 3 dimensional dataset by rendering it on-the-fly. Here we present simulation data created as part of the FIRE galaxy formation collaboration. Interactively exploring data generates powerful intuition and helps one isolate regions of interest in the data using...
