Gemini South Helps Discover Galactic Jet in Spiral Galaxy
9 January 2003: Gemini South Assistant Astronomer Dr. Michael Ledlow has helped confirm the existence of a giant, subatomic particle jet streaming from a spiral galaxy similar to the Milky Way. Though long known to be associated with elliptical and merging galaxies, the discovery of such jets streaming from a spiral galaxy raises significant questions about current theories on jet production. The discovery was made possible by the combination of radio, optical and infrared observations. The findings were reported at the American Astronomical Society's meeting in Seattle. Dr. Ledlow's infrared work at Gemini South was instrumental in complementing research by the team leader, Dr. William Keel with the University of Alabama, and Dr. Frazer Owen with the National Radio Astronomy Observatory. The galaxy, known as 0313-192, first came to the attention of Dr. Owen more than 20 years ago during a galaxy survey he conducted using the Very Large Array (VLA). Gemini South's …
