cooling and star formation, in a process called feedback.
Observations by NASA’s Chandra X-ray Observatory and by GBO’s MUSTANG-2 instrument clearly show the enormous cavities excavated by the powerful radio jets expelled from the black hole at the center of galaxy cluster MS0735. The green contours in both images are from observations performed by the Naval Research Laboratory’s VLA Low-band Ionosphere and Transient Experiment back end used on the National Radio Astronomy Observatory’s Very Large Array .
“With the power of MUSTANG-2, we are able to see into these cavities and start to determine precisely what they are filled with, and why they don’t collapse under pressure,” elaborates Tony Mroczkowski, an astronomer with the European Southern Observatory who was part of this new research.
