The People Behind the Very Large Array
Zach Gallegos is a shining example of dedication and hard work. His journey from a security guard to the HVAC and Plumbing lead at the VLA is inspiring. Despite the challenges, he continues to serve with grit and determination, ensuring the smooth operation of the VLA. His story serves as a reminder that with passion and dedication, one can achieve great heights in any field.
Book Release: “Joe Pawsey and the Founding of Australian Radio Astronomy”
This book was more than 15 years in the making, and it is a collaboration of three authors across two continents who worked together to bring to light the story of Joe Pawsey, a key figure in Australian science and, especially, radio astronomy.
VLA Finds Cosmic Rays Driving Galaxy’s Winds
VLA observations revealed that cosmic rays can play an important role in driving winds that rob galaxies of the gas needed to form new stars. This mechanism may be an important factor in galactic evolution, particularly at earlier times in the history of the universe.
Strange Radio Burst Raises New Questions
A highly active repeating Fast Radio Burst is raising new questions about the nature of such objects, and also raising doubts about their usefulness as cosmic yardsticks.
VLA Reveals Double-Helix Structure in Massive Galaxy’s Jet
Astronomers used the VLA to trace a corkscrew-shaped magnetic field in a powerful jet of material ejected from the core of a massive galaxy farther away from the central galaxy’s central black hole than ever seen before. The new images provide clues that will help understand the mechanics of such jets, which are seen throughout the Universe.
