Observations with the continent-wide Very Long Baseline Array (VLBA) reveal previously unseen details in a jet of material ejected from the core of a galaxy seen as it was when the universe was only about 7 percent of its current age.
IMAGE RELEASE: Galaxies in the Perseus Cluster
New VLA images show how the crowded environment of a cluster of galaxies affects the individual galaxies, helping astronomers better understand some of the complex details of such an environment.
NRAO Contest Winners Illustrate Diverse Cosmic Phenomena
Winners in NRAO’s VLA 40th Anniversary Image Contest are from around the world, and their works illustrate a fascinating variety of celestial objects. Entries combined observational data from the VLA with data from optical, infrared, and X-ray telescopes, and from computer simulations.
AAS Names NRAO Astronomer as Fred Kavli Plenary Lecturer
NRAO astronomer Paul B. Demorest has been selected to give the Fred Kavli Plenary Lecture at the 237th meeting of the American Astronomical Society, to be held virtually, on 11 January 2021.
Astronomers Find Wandering Massive Black Holes in Dwarf Galaxies
Studies with the VLA indicate that roughly half of the massive black holes in dwarf galaxies are not in the centers of those galaxies. This gives astronomers new insights into the conditions in which similar black holes formed and grew in the early history of the Universe.
A Weakened Black Hole Allows its Galaxy to Awaken
Astronomers have found the first example of a galaxy cluster where large numbers of stars are being born at its core. The discovery revealed new details of how supermassive black holes affect their host galaxies.
