Theoretical Mid-Infrared Modeling of Starburst Galaxies
نویسندگان
چکیده
We investigated the ability of the stellar models Starburst99 and MappingsIII to model starburst galaxies using infrared diagnostics and Spitzer data. The infrared diagnostics were useful for distinguishing between starforming galaxies and AGN. The theoretical starburst models indicate that the infrared emission-line ratios are largely degenerate and are extremely sensitive to the age of the stellar population and the star formation history prescription (instantaneous versus continuous). Additional information from the near-infrared or optical spectra are required to resolve the degeneracies encountered in the infrared emission-line ratios.

Mid - infrared and optical spectroscopy of ultraluminous infrared galaxies : A comparison
New tools from Infrared Space Observatory (ISO) mid-infrared spectroscopy have recently become available to determine the power sources of dust-obscured ultraluminous infrared galaxies (ULIRGs). We compare ISO classifications – starburst or active galactic nucleus (AGN) – with classifications from optical spectroscopy, and with optical/near-infrared searches for hidden broad-line regions. The a...
متن کاملActive Galactic Nucleus and Starburst Classification from Spitzer Mid‐Infrared Spectra for High‐Redshift SWIRE Sources
Spectra have been obtained with the Infrared Spectrograph ( IRS) on the Spitzer Space Telescope for 20 sources in the Lockman Hole field of the SWIRE survey. The sample is divided between sources with indicators of an obscured AGN, based primarily on X-ray detections of optically faint sources, and sources with indicators of a starburst, based on optical and near-infrared spectral energy distri...
متن کاملMid-Infrared Images of Luminous Infrared Galaxies in a Merging Sequence
We report mid-infrared observations of several luminous infrared galaxies (LIGs) carried out with the Infrared Space Observatory (ISO). Our sample was chosen to represent different phases of a merger sequence of galaxy-galaxy interaction with special emphasis on early/intermediate stages of merging. The mid-infrared emission of these LIGs shows extended structures for the early and intermediate...

and – 2 – ABSTRACT Observations of ultraluminous infrared galaxies (ULIRGs) with an achieved resolution approaching the diffraction limit in the mid-infrared from 8-25 µm using the Keck Telescopes are reported. We find extremely compact structures, with spatial scales of < 0.3 ′′ (diameter) in six of the seven ULIRGs observed. These compact sources emit between 30% and 100% of the mid-infrared ...
متن کاملSpatial resolution bias in the mid - infrared Starburst / AGN classification
We present the effects of limited spatial resolution to the observed mid-infrared (MIR) spectrum of an active galactic nucleus (AGN) surrounded by a disk with massive star forming regions. Using MIR observations of the face-on nearby Seyfert 1 galaxy NGC 6814, we vary the observing aperture and examine the evolution of the observed AGN/starburst fraction with our MIR diagnostic. We show that th...
