The double AGN in NGC 6240 revealed through 3-5 micron spectroscopy
G. Risaliti, E. Sani, R. Maiolino +7
We present 3-5 micron spectroscopy of the interacting system NGC 6240, showing the presence of two active galactic nuclei. The brightest (southern) nucleus shows up with a starburs…
Remarkable Disk and Off-nuclear Starburst Activity in the "Tadpole Galaxy" as revealed by the Spitzer Space Telescope
T. H. Jarrett, M. Polletta, I. P. Fournon +20
We present ground-based optical and Spitzer infrared imaging observations of the interacting galaxy UGC 10214, the "Tadpole Galaxy" (z = 0.0310), focusing on the star formation act…
Unveiling the nature of Ultraluminous Infrared Galaxies with 3-4 micron spectroscopy
G. Risaliti, R. Maiolino, A. Marconi +6
We present the results of L-band spectroscopical observations of local bright ULIRGs, performed with ISAAC at the VLT. We discuss the L-band spectral features of seven single sourc…
FORS spectroscopy of galaxies in the Hubble Deep Field South
Dimitra Rigopoulou, William D. Vacca, Stefano Berta +2
We present low resolution multi-object spectroscopy of an I-band magnitude limited (I_{AB} ~ 23--23.5) sample of galaxies located in an area centered on the Hubble Deep Field-South…
