A Spitzer Mid-Infrared Study of Active Galactic Nuclei with Outflows
… both BAL and non-BAL quasars obtained with the Spitzer Space Telescope. We find the BALQSOs have an average equivalent width 40% larger and an average MIR-optical luminosity ratio 40% smaller than the ControlQSOs. We explore the physical meaning behind these results.

Investigating strong gravitational lensing with infrared space missions : AKARA, Spitzer and Herschel
… components in highly photometrically blended <i>Spitzer</i> data, after observations by the Submillimeter Array revealed the lensed structure. The lensed background galaxies are highly dust obscured SMG with intrinsic infrared luminosities < ultra luminous infrared galaxies (ULIRGs), and …

From Spitzer mid-infrared observations and measurements of peculiar velocities to constrained simulations of the local universe
… in the mid-infrared with observational data from Spitzer Space Telescope. Resulting accurate distance estimates will be included in the third catalog of the project. In the meantime, two catalogs up to 30 and 150 Mpc/h have been released. We report improvements and applications of the CLUES' …

Alone at home: post-9/11 military veterans and American housing and homelessness policy by Kerry Anna Spitzer.
The social safety net available to veterans is far more robust than for civilians in the United States, however, veterans are still more likely to experience homelessness than their peers. As the number of veterans from the wars in Afghanistan and Iraq continues to increase, it is essential that …

Deconstructing the WISE nearby galaxy population
… of the two indicators. Our sample consists of Spitzer galaxies from the SINGS and KINGFISH surveys, with a select few excluded. The TIR calibration also necessitates that most of our galaxies have FIR data from Herschel. The photometric analysis done on the raw WISE and Spitzer images of our …

Help-seeking intentions and perceived stigma : a survey among university students in Iceland
… the Patient Health Questionnaire-9 (Kroenke, Spitzer & Williams, 2001) and anxiety symptoms were assessed with the General Anxiety Disorder-7 (Spitzer, Kroenke, Williams, & Löwe, 2006). Results revealed differences between age, gender, university, degree level, marital status, living …

Lenticular galaxies - the one in the middle
… A sample of lenticular galaxies from the Spitzer Survey of Stellar Structure in Galaxies (S4G) using the Spitzer Space Telescope along with Sloan Digital Sky Survey (SDSS) was used for this project to study molecular gas properties as well morphologies associated with dust where molecular …

Dust disks around hot white dwarfs and central stars of planetary nebulae
… disks of the latter type, we have carried out a Spitzer MIPS 24 um survey of 71 hot WDs or pre-WDs, and found nine WDs with excess 24 um emission, seven of which are still central stars of planetary nebulae (CSPNs). We have therefore used archival Spitzer IRAC and MIPS observations of PNe to …

Equipartition and mass segregation : simulations of star clusters with two mass-components
… the different masses, a phenomenon known as the Spitzer equipartition instability; the heavy component decouples and collapses under the influence of the gravothermal instability of its own subsystem. For the first time the critical boundary between Spitzer-stable and -unstable systems is …

Observations, Thermochemical Calculations, and Modeling of Exoplanetary Atmospheres
… and modeling their atmospheres. We used Spitzer multi-wavelength secondary-eclipse observations to characterize planetary atmospheres. We chose targets with high signal-to-noise ratios, as their deep eclipses allow us to detect signatures of spectral features and assess planetary …

Depressive and anxiety symptoms among university students in Iceland
… symptoms were measured with the PHQ-9 (Kroenke, Spitzer & Williams, 2001), anxiety symptoms were measured with GAD-7 (Spitzer, Kroenke, Williams, & Löwe, 2006) and to measure quality of life we used the Quality of Life Scale (Burckhardt & Anderson, 2003). The estimated prevalence of clinically …

Ion Cyclotron Resonance Heating Induced Transport in Stellarators and Other Asymmetric Toroids
… on a Coulomb scattering model that contains the Spitzer coefficients of drag, velocity diffusion, and pitch angle scattering (PAS). Ion drift orbit equations of motion are set in a magnetic flux coordinate system which separate fast motion along the field lines from slow motion across the lines.

Star formation in the bars of nearby galaxies
… galaxies in the nearby universe taken from the Spitzer Survey of Stellar Structure in Galaxies (S⁴G). The data are combined with Hα data from various optical telescopes. (KPNO, JKT, OHP and CTIO) Methods: We overlay continuum-subtracted Hα emission on 3.6μm images from Spitzer (S⁴G) to quantify …
