Bad Astra Interviews Maya Fishbach

Maya Fishbach uses gravitational waves to probe the universe’s most extreme objects — black holes and neutron stars. Her research aims to understand where, when and how these systems of merging compact objects are made. As a member of the LIGO Scientific Collaboration, she analyzes gravitational-wave data to study the population properties of colliding black

Black Hole Accretion Disk

The massive black hole in M33 X-7 is hidden in the X-ray bright center of the pancake-like accretion disk of matter. The black-hole’s hot (blue) and massive star companion is losing mass in a wind that gets pulled and captured by the black hole. Learn more.

Great Conjunction 2020

PhD student Newlin Weatherford, who holds the Riedel Family Graduate Fellowship at CIERA, captured the Great Conjunction (“Christmas Star”) of Jupiter and Saturn on December 21, 2020 at 6:20 pm PT from Novato, California. Using his Panasonic DZ1000, Newlin wasn’t able to resolve Saturn’s rings, but we can see Callisto and Io and many faint

Models and Simulations Run on the Cluster and in the Family

From Purdue University’s Long Tales of Science podcast, hear CIERA’s Dr. Sarah Wellons, an astrophysicist who uses high performance computing resources to run massive simulations of galaxy formation, and her mother, Dr. Helen Wellons, a retired chemical engineer who used parallel computing to deploy computational modeling applications to optimize real-time refinery operations at ExxonMobil.

LIGO-Virgo Discoveries Over Time

This movie shows the increasing sample of gravitational wave sources, starting before LIGO-Virgo went online (with only electromagnetic, EM, sources) and then moving through the three observing runs of data that are now available (O1, O2, and O3a). Watch as the sample of merging black holes and neutron stars has dramatically increased over the past

Shane Larson’s Virtual Public Lecture, “A Storm of Stars: A Living History of the Milky Way”

On October 28, 2020 CIERA’s Shane Larson presented this public lecture titled A Storm of Stars: A Living History of the Milky Way in a virtual Zoom webinar format to an audience of nearly 450 viewers. Larson discussed how we came to understand the Milky Way, our home galaxy, and how our ideas about the
