The Joint Milli-Arcsecond Pathfinder Survey (JMAPS): Mission Overview and Attitude Sensing Applications
Bryan N. Dorland, Rachel P. Dudik, Zachary Dugan +1
The Joint Milliarcsecond Pathfinder Survey (JMAPS) is a Department of Navy bright star astrometric all-sky survey scheduled for launch in the 2012 timeframe. Mission objectives inc…
Spitzer Uncovers Active Galactic Nuclei Missed by Optical Surveys in 7 Late-type Galaxies
S. Satyapal, D. Vega, R. P. Dudik +2
We report the discovery using Spitzers high resolution spectrograph of 7 Active Galactic Nuclei (AGN) in a sample of 32 late-type galaxies that show no definitive signatures of AGN…
Mid-Infrared Fine Structure Line Ratios in Active Galactic Nuclei Observed with Spitzer IRS: Evidence for Extinction by the Torus
R. P. Dudik, J. C. Weingartner, S. Satyapal +3
We present the first systematic investigation of the [NeV] (14um/24um) and [SIII] (18um/33um) infrared line flux ratios, traditionally used to estimate the density of the ionized g…
The PAH Emission Deficit In Low-Metallicity Galaxies - A Spitzer View
B. O'Halloran, S. Satyapal, R. P. Dudik
Archival observations of 18 starburst galaxies that span a wide range in metallicity reveal for the first time a correlation between the ratio of emission line fluxes of [FeII] at…
The Link Between Star Formation and Accretion in LINERs: A Comparison with other AGN Subclasses
S. Satyapal, R. P. Dudik, B. O'Halloran +1
We present archival high resolution X-ray imaging observations of 25 nearby LINERs observed by ACIS on board Chandra. This sample builds on our previously published proprietary and…
A Chandra Snapshot Survey of IR-bright LINERs: A Possible Link Between Star Formation, AGN Fueling, and Mass Accretion
R. P. Dudik, S. Satyapal, M. Gliozzi +1
We present results from a high resolution X-ray imaging study of nearby LINERs observed by Chandra. This study complements and extends previous X-ray studies of LINERs, focusing on…
