NGC 1559 is a barred spiral galaxy in the constellation Reticulum. It was discovered on 6 November 1826 by Scottish astronomer James Dunlop. [2]

Contents

NGC 1559 is a Seyfert galaxy, i.e. it has a quasar-like nuclei with very high surface brightnesses whose spectra reveal strong, high-ionisation emission lines, but unlike quasars, the host galaxy is clearly detectable. Although it was originally thought to be a member of the Dorado Group, [3] subsequent observations have shown that it is in fact not a member of any galaxy group or cluster and does not have any nearby companions. [4] [5] NGC 1559 has massive spiral arms and strong star formation. [4] It contains a small bar which is oriented nearly east-west and spans 40″. [4] Its bar and disc are the source of very strong radio emissions. [4]
