Spitzer IRAC observations of JWST calibration stars
Jessica E. Krick, Patrick Lowrance, Sean Carey +10
We present infrared photometry of all 36 potential JWST calibrators for which there is archival Spitzer IRAC data. This photometry can then be used to inform stellar models necessa…
Variability Timescale and Spectral Index of Sgr A* in the Near Infrared: Approximate Bayesian Computation Analysis of the Variability of the Closest Supermassive Black Hole
G. Witzel, G. Martinez, J. Hora +16
Sagittarius A* (Sgr A*) is the variable radio, near-infrared (NIR), and X-ray source associated with accretion onto the Galactic center black hole. We present an analysis of the mo…
The Stellar Populations of Two Ultra-Diffuse Galaxies from Optical and Near-infrared Photometry
Viraj Pandya, Aaron J. Romanowsky, Seppo Laine +11
We present observational constraints on the stellar populations of two ultra-diffuse galaxies (UDGs) using optical through near-infrared (NIR) spectral energy distribution (SED) fi…
Spitzer Space Telescope Mid-IR Light Curves of Neptune
J. R. Stauffer, M. S. Marley, J. E. Gizis +9
We have used the Spitzer Space Telescope in February 2016 to obtain high cadence, high signal-to-noise, 17-hour duration light curves of Neptune at 3.6 and 4.5 m. The light curv…
Repeatability and Accuracy of Exoplanet Eclipse Depths Measured with Post-Cryogenic Spitzer
James G. Ingalls, J. E. Krick, S. J. Carey +15
We examine the repeatability, reliability, and accuracy of differential exoplanet eclipse depth measurements made using the InfraRed Array Camera (IRAC) on the Spitzer Space Telesc…
A Spitzer IRAC Measure of the Zodiacal Light
Jessica E. Krick, William J. Glaccum, Sean J. Carey +5
The dominant non-instrumental background source for space-based infrared observatories is the zo- diacal light. We present Spitzer Infrared Array Camera (IRAC) measurements of the…
