Exploring the Invisible Universe with Computer Simulations

Northwestern Physics and Astronomy student Alex Gurvich presents a talk as part of the Northwestern Ready Set Go (RSG) program. The goals of the program are to increase awareness for the urgent need for excellent research communicators and to coach graduate and post doctoral researchers to improve their own presentation skills. The program focuses on three important

Isolated Disc Galaxy

Simulation of an isolated disc galaxy, looking at the disc of the galaxy face on (top panels) and edge on (bottom panels). The left-hand panels show images of the stellar light, and is what we would see if we viewed this galaxy with a telescope such as Hubble. The right-hand panels show the gas in

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

Firefly Demonstration

Firefly Demonstration

Firefly is a portable web-based 3d visualization software developed in partnership between the Northwestern University Galaxy Formation and Visualization groups. It was developed with the data output of the FIRE simulations in mind but can visualize any 3d dataset (in coordinate or phase space). In this video I demonstrate some of the key features of

Galaxy Evolution

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 visualization platform available at ageller.github.io/Firefly. 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 and dark matter is invisible, so
