By studying nearby galaxy ESO320-G030, a team of international astronomers led by CIERA Postdoctoral Fellow Mark Gorski has discovered extremely dense and powerful rotating, magnetic winds help the galaxy’s central supermassive black hole grow. This image, created by CIERA Professor Aaron Geller, depicts this phenomenon. The process is strikingly similar to the birth of new

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. This

A 31.5 solar-mass black hole with an 8.38 solar-mass black hole companion viewed in front of its (computer generated) stellar nursery prior to merging. 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

A Northwestern University-led team of astronomers has developed the most extensive inventory to date of the galaxies where short gamma-ray bursts (SGRBs) originate. Using several highly sensitive instruments and sophisticated galaxy modeling, the researchers, including Anya Nugent, pinpointed the galactic homes of 84 SGRBs and probed the characteristics of 69 of the identified host galaxies.

A still image taken from the 3D simulation of the natural development of an X-shaped jet. The gas (bright red) falls into the black hole, which launches a pair of relativistic jets (light blue). The jets propagate vertically and shock the ambient gas (dark red). The older cavities (dark blue) buoyantly rise at an angle

On Aug. 21, the NASA-funded team launched its “Micro-X” rocket from White Sands Missile Range in southern New Mexico. The rocket spent 15 minutes in space — just enough time to snap a quick image of supernova remnant Cassiopeia A, a star in the Cassiopeia constellation that exploded approximately 11,000 light-years away from Earth. Then,
