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…
The Evolution of the Broad-Line Region among SDSS Quasars
Tohru Nagao, Alessandro Marconi, Roberto Maiolino
Based on 5344 quasar spectra taken from the SDSS Data Release 2, the dependences of various emission-line flux ratios on redshift and quasar luminosity are investigated in the rang…
Disk and wind interaction in the young stellar object MWC 297 spatially resolved with VLTI/AMBER
F. Malbet, M. Benisty, W. J. De Wit +15
The young stellar object MWC 297 has been observed with the VLT interferometer equipped with the AMBER instrument. MWC 297 has been spatially resolved in the continuum with a visib…
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…
An Observational Pursuit for Population III Stars in a Ly_alpha Emitter at z=6.33 through HeII Emission
Tohru Nagao, Kentaro Motohara, Roberto Maiolino +5
We present a very deep near-infrared spectroscopic observation of a strong Ly_alpha emitter at z=6.33, SDF J132440.6+273607, which we used to search for HeII 1640. This emission li…
