The length of a human life barely registers on the scale of cosmic time. In spite of our relatively tiny size and our limited time here on Earth, a single generation of humans can take giant leaps forward in our understanding of the Universe. Join us to find out how dramatically our story of the

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.

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

Density (top) and temperature (bottom) snapshots from an idealized hydro-simulation of the circum-galactic medium of a Milky-Way-like galaxy. Note the outskirts (>70 kpc) are cool and free-falling, while the inner region is hot and pressure-supported.

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 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

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

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

In this movie, 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 density). Thus diffuse and hot gas looks like a hazy green mist while cold and dense gas looks

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,
