Radiative-hydrodynamic Simulation of a Dusty Cloud Irradiated by a Quasar

The figure shows a radiative-hydrodynamic simulation of a dusty cloud irradiated by a quasar (located at r = 0). Radiation pressure is set to be the dominant pressure source. Left panel shows the initial conditions, while the right panel shows the cloud 10^4 years after exposure to the quasar radiation. A quasi-static density gradient develops at

Galaxy Evolution

Here we show the evolution of a Milky Way-like galaxy over time. The top row shows the galaxy as it would appear today, the middle 3.5 billion years ago, and the bottom almost 10 billion years ago. Columns give different views of the same snapshot in time, leftmost is the mock view through the Hubble

Firefly Visualization Platform

A screenshot from Firefly, an interactive, web-based, and publicly available particle visualization platform created by Aaron Geller and Alex Gurvich. Shown here is a snapshot in time from a simulation of a Milky Way-like galaxy with the stars in blue, the gas in red, and the dark matter in yellow. In the real universe the gas

One Galaxy, Multiple Perspectives

This collection of images shows gas swirling around the same galaxy in several different ways. Taken together, the columns create a time-lapse projection. The top row shows the density of gas in the galaxy at a given time: in these panels, the brightest areas show where gas is most densely concentrated. In the middle row,
