CIERA’s 10th Annual Public Lecture, “The NU Astronomy of Stars, Black Holes, and Cosmic Explosions”

CIERA’s 10th annual public lecture was presented October 11, 2018 by director Vicky Kalogera. Kalogera’s talk–a glimpse into the years of fascinating work conducted by CIERA–highlighted key discoveries and what they mean for the future of astronomy. Kalogera discussed the lives of stars, how their influence on the Cosmos has changed in the recent decade,

How many merger binary black holes are there?

How many merger binary black holes are there?

How many merger binary black holes are there? There are lots of uncertainties in our understanding of stellar evolution. This plot shows one prediction from the COMPAS population synthesis code for the number of gravitational-wave detections:  there would be about 500 detections per year of observing time once our detectors reach design sensitivity!

Northwestern Physics and Astronomy student Mike Zevin 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

Dynamical Evolution of Star Clusters

This movie, Life of the Pleiades, was generated from an interactive visualization that Aaron Geller developed with Mark SubbaRao using Uniview. The interactive version can be shown on a planetarium dome, or rendered into a movie (as shown here). A 3D version of this movie exists in the Space Visualization Lab at the Adler Planetarium.

Created by A. M. Geller and M. SubbaRao, using Uniview; music, narration and audio by A. M. Geller; dynamical calculation with stellar evolution performed using the NBODY6 code.

Black Hole Encounter

In late 2015, LIGO discovered gravitational waves emitted by two black holes (each with a mass of about 30 times that of our Sun) that spiraled together and merged about 1.5 billion years ago. Astrophysicists are now debating which is the most likely mechanism that can bring two black holes like those observed so close
