The ~0.9 mJy sample: A mid-infrared spectroscopic catalog of 150 infrared-luminous, 24 micron selected galaxies at 0.3<z<3.5
Kalliopi M. Dasyra, Lin Yan, George Helou +6
We present a catalog of mid-infrared (MIR) spectra of 150 infrared (IR) luminous galaxies in the Spitzer extragalactic first look survey obtained with IRS on board Spitzer. The sam…
First Stellar Velocity Dispersion Measurement of a Luminous Quasar Host with Gemini North Laser Guide Star Adaptive Optics
Linda C. Watson, Paul Martini, Kalliopi M. Dasyra +5
We present the first use of the Gemini North laser guide star adaptive optics (LGS AO) system and an integral field unit (IFU) to measure the stellar velocity dispersion of the hos…
HST NICMOS imaging of z~2, 24 micron-selected Ultraluminous Infrared Galaxies
Kalliopi M. Dasyra, Lin Yan, George Helou +3
We present Hubble Space Telescope NICMOS H-band imaging of 33 Ultraluminous Infrared Galaxies (ULIRGs) at z~2 that were selected from the 24 micron catalog of the Spitzer Extragala…
High-ionization mid-infrared lines as black hole mass and bolometric luminosity indicators in active galactic nuclei
K. M. Dasyra, L. C. Ho, L. Armus +6
We present relations of the black hole mass and the optical luminosity with the velocity dispersion and the luminosity of the [Ne V] and the [O IV] high-ionization lines in the mid…
Spitzer Quasar and ULIRG Evolution Study (QUEST): II. The Spectral Energy Distributions of Palomar-Green Quasars
Hagai Netzer, Dieter Lutz, Mario Schweitzer +10
This is the second paper studying the QSOs in the spitzer QUEST sample. Previously we presented new PAH measurements and argued that most of the observed far infrared (FIR) radiati…
Host dynamics and origin of Palomar-Green QSOs
K. M. Dasyra, L. J. Tacconi, R. I. Davies +7
We present host-galaxy velocity dispersions of 12 local (mainly Palomar-Green) quasi-stellar objects (QSOs) measured directly from the stellar CO absorption features in the H band.…
