Two New Planetary Nebulae and an AGN in the Galactic Plane

摘要

A search for planetary nebulae was carried out using candidates selected by their infrared colours and 5 GHz radio emission. One new planetary nebula was identified on the basis of its small angular size, strong [O iii] emission and infrared colours. Another object, known as the possible planetary nebula Wray 16a€“28, is similarly identified as a planetary nebula. An undiscovered AGN was also found, and is classed as a Seyfert 2 galaxy on the basis of its strong O iii emission, linewidths of a??500 km sa?’1, and 5 GHz radio flux. Low-resolution optical spectra are presented and distance estimates discussed.
