Discovery of Radio Jets in <i>z</i> ~ 2 Ultraluminous Infrared Galaxies with Deep 9.7 μm Silicate Absorption

Recent Spitzer observations have revealed a substantial population of z ~ 2 ultraluminous infrared galaxies (ULIRGs) with deep silicate absorption (τ9.7 > 1). This paper reports a 20 cm radio study of such a sample to elucidate their physical nature. We discover that a substantial fraction (40%) of deep silicate …
