We’ve strongly suspected they’re there. A new method promises to prove it.
Using super high resolution data from ALMA and the VLA, the authors of this paper resolve star formation in active galaxies — and find that active galactic nuclei are embedded inside central star-forming regions.
Last week, over 1400 astronomers met at the European Week of Astronomy and Space Sciences in Liverpool. From observations of high-redshift galaxies, to simulations of the universe and starquakes, we give you an eclectic mixture of highlights of the week.
What is responsible for the excess radio emission from our nearest star, Proxima Centauri? No alien radio stations required!
Astronomers using ALMA have just discovered that our closest neighbor has at least one dust ring, analog to the Kuiper belt in the solar system. Sorry, but a reference to Lord of the Rings is unavoidable.
Turbulence plays a key role in determining what types of planets can form in a disk. We are finally on the verge of measuring this property for the first time using CO spectral lines, but it will only work if we factor in how quickly CO can be depleted.
