AGN Dusty Tori: I. Handling of Clumpy Media
Maia Nenkova, Matthew M. Sirocky, Zeljko Ivezic +1
According to unified schemes of Active Galactic Nuclei (AGN), the central engine is surrounded by dusty, optically thick clouds in a toroidal structure. We have recently developed…
Silicates in Ultra-Luminous Infrared Galaxies
M. M. Sirocky, N. A. Levenson, M. Elitzur +2
We analyze the mid-infrared (MIR) spectra of ultraluminous infrared galaxies (ULIRGs) observed with the Spitzer Space Telescope's Infrared Spectrograph. Dust emission dominates the…
Deep Mid-Infrared Silicate Absorption as a Diagnostic of Obscuring Geometry Toward Galactic Nuclei
N. A. Levenson, M. M. Sirocky, L. Hao +4
The silicate cross section peak near 10um produces emission and absorption features in the spectra of dusty galactic nuclei observed with the Spitzer Space Telescope. Especially in…
