In-flight performance and calibration of the Infrared Array Camera (IRAC) for the Spitzer Space Telescope

TL;DR: Spitzer and Chandra observations of the nearby (~260 pc) embedded stellar cluster in the Serpens cloud core were used to detect thermal emission from circumstellar disks and protostellar envelopes and to classify stars using color-color diagrams and SEDs as mentioned in this paper.

TL;DR: In this article, a uniform analysis of eight transits and eleven secondary eclipses of the extrasolar planet GJ 436b obtained in the 3.6, 4.5, and 8.0 μm bands using the IRAC instrument on the Spitzer Space Telescope between UT 2007 June 29 and UT 2009 February 4 was presented.

TL;DR: In this paper, a census of disks in the Chamaeleon I star-forming region was presented, where the authors used the Infrared Array Camera and the Multiband Imaging Photometer onboard the Spitzer Space Telescope.

TL;DR: In this paper, a spectral energy distribution (SED) fitting approach was proposed to select radio-excess sources amongst distant star-forming galaxies in the GOODS-Herschel (North) field and to reveal the presence of hidden, highly obscured AGN.

TL;DR: The Infrared Array Camera (IRAC) is one of the three focal plane instruments in the Spitzer Space Telescope as discussed by the authors, which is a four-channel camera that obtains simultaneous broadband images at 3.6, 4.5, 5.8, and 8.0 microns.

Abstract: 1  Abstract—The upper atmosphere is a transition region between the neutron-dominated aviation environment and satellite environment where primary protons and ions dominate. We report high altitude balloon measurements and model results characterising this radiation environment for single event effects (SEE) in avionics. Our data, from the RaySure solid-state radiation monitor, reveal markedly different altitude profiles for low linear energy transfer (LET) and high LET energy depositions. We use models to show that the difference is caused by the influence of primary cosmic ray particles, which induce counts in RaySure via both direct and indirect ionization. Using the new Model of Atmospheric Ionizing Radiation Effects (MAIRE), we use particle fluxes and LET spectra to calculate single event upset (SEU) rates as a function of altitude from ground level to the edge of space at 100 km altitude. The results have implications for a variety of applications including high altitude space tourism flights, UAVs and missions to the Martian surface.
