The role of nuclear activity as the power source of ultraluminous infrared galaxies
E. Nardini, G. Risaliti, Y. Watabe +2
We present the results of a 5-8 micron spectral analysis performed on the largest sample of local ultraluminous infrared galaxies (ULIRGs) selected so far, consisting of 164 object…
The AGN/starburst content in high redshift ULIRGs
Y. Watabe, G. Risaliti, M. Salvati +3
We apply a simple model, tested on local ULIRGs, to disentangle the active galactic nucleus (AGN) and starburst contributions in submillimiter and 24um-selected ULIRGs observed wit…
Exploring the active galactic nucleus and starburst content of local ultraluminous infrared galaxies through 5-8 micron spectroscopy
E. Nardini, G. Risaliti, M. Salvati +4
We present a 5-8 micron analysis of the Spitzer-IRS spectra of 71 ultraluminous infrared galaxies (ULIRGs) with redshift z < 0.15, devoted to the study of the role of active galact…
Supermassive Black Hole Mass Regulated by Host Galaxy Morphology
Y. Watabe, N. Kawakatu, M. Imanishi +1
We investigated the relationship between supermassive black hole (SMBH) mass and host starburst luminosity in Seyfert galaxies and Palomar-Green QSOs, focusing on the host galaxy m…
