AINUR

The Atlas of Images of NUclear Rings (AINUR) is a catalogue of nuclear rings, which are enormous star-forming ring-shaped regions that circle certain galactic nuclei. The first edition of the atlas was published in 2010 in the Monthly Notices of the Royal Astronomical Society, and includes 113 such rings in 107 galaxies. The catalogue resulted from a joint study by researchers from the Institute of Astrophysics of the Canary Islands (IAC) and the universities of La Laguna, Oulu and Alabama led by Sébastien Comerón from the IAC.
