Supermassive black holes at the centers of galaxies, elusive intermediate mass black holes, and dead stars in the form of black holes, neutron stars, or white dwarfs, are the densest objects in the Universe. They are central players in much of modern astrophysics, but we have only been aware of and studying these objects for less than a century. Our observational record is less than five decades long. As such, there are still many unanswered questions about how these systems form and evolve over cosmic time. CIERA is home to a broad group of researchers in theory, simulation, and observation that study these exotic objects.
Research at CIERA
Few things in the Universe are as dramatic as the death of a star. Transient events like supernovae, gamma ray bursts, and tidal disruptions of stars encountering massive black holes, are all astoundingly bright and carry information about the star that died, how it tore itself apart, and the fragments that remain.
Professor Fong observes short gamma ray bursts to learn about the neutron star and black hole mergers that give rise to these intense explosions.
Professor Miller observes Type Ia supernovae to understand the conditions and environments under which white dwarf stars explode.

Simulated image of an accretion disk, the violent whirlpool of gas that encircles a supermassive black hole, broken apart into inner and outer rings. According to new high-resolution 3D simulations, spinning black holes twist up the surrounding space-time, ultimately ripping apart the violent whirlpool of gas (or accretion disk) that encircles and feeds them.

Unprecedented gamma-ray burst explained by long-lived jet
Unprecedented gamma-ray burst explained by long-lived jet
Last year, Northwestern University researchers uncovered new observational evidence that long gamma-ray bursts (GRBs) can result from the merger of a neutron star with another compact object (either another neutron star or black hole) — a finding that was previously believed to be impossible. Now, another Northwestern team offers a potential explanation for what generated

The distant band of the Milky Way can be seen toward the lower-left of the black hole pair. Light is warped nearby the black holes due to their strong gravity. The
