Wandering Massive Black Holes Detected in Nearby Dwarf Galaxies

An artist’s conception of a dwarf galaxy, its shape distorted, most likely by a past interaction with another galaxy, and a massive black hole in its outskirts (pullout). The black hole is drawing in material that forms a rotating disk and generates jets of material propelled outward. Image credit: Sophia Dagnello, NRAO / AUI / NSF.

Astronomers using NSF’s Karl G. Jansky Very Large Array (VLA) at the National Radio Astronomy Observatory have observed 111 nearby dwarf galaxies within one billion light-years from Earth. They have identified 13 dwarf galaxies that host very massive black holes. These galaxies, more than 100 times less massive than our own Milky Way, are among the smallest galaxies known to host massive black holes. In roughly half of these galaxies, the black...

This Hubble image shows NGC 1022, a face-on barred spiral galaxy located in the constellation of Cetus, approximately 62 million light-years away. The image is made up of observations from Hubble’s Wide Field Camera 3 (WFC3) in the infrared and optical parts of the spectrum. Three filters were used to sample various wavelengths. The color results from assigning different hues to each monochromatic image associated with an individual filter. Image credit: NASA / ESA / Hubble / A. Seth.

This infographic shows the key results from a study that has revealed the interstellar thread of phosphorus. The background of the infographic shows a part of the night sky in the constellation of Auriga, where the star-forming region AFGL 5142 is located. The ALMA image of this object is on the top left of the infographic, and one of the locations where the team found phosphorus-bearing molecules is indicated by a circle. The most common phosphorus-bearing molecule in AFGL 5142 is phosphorus monoxide, represented in orange and red in the diagram on the bottom left. Another molecule found was phosphorus nitride, represented in orange and blue. The astronomers also found phosphorus monoxide on 67P/Churyumov-Gerasimenko, shown on the bottom right.
