Molecular gas and star formation in the host galaxy of I Zw 1

Schinnerer, Eva; Eckart, Andreas; Tacconi, Linda

A recent analysis of high angular resolution NIR imaging and spectroscopic data in conjunction with Plateau de Bure interferometric mm-line observations indicate the presence of a circum-nuclear starburst ring of ∼1.5″ (1.5 kpc) diameter in I Zw 1. High angular resolution NIR imaging, using the MPE SHARP camera at the ESO NTT, HST V-band images, a…
