Photometry using the Infrared Array Camera on the Spitzer Space Telescope
We present several corrections for point-source photometry to be applied to data from the Infrared Array Camera (IRAC) on the Spitzer Space Telescope. These corrections are necessary because of
Optical conductivity of manganites: Crossover from Jahn-Teller small polaron to coherent transport in the ferromagnetic state
We report on the optical properties of the hole-doped manganites ${\mathrm{Nd}}_{0.7}{\mathrm{Sr}}_{0.3}{\mathrm{MnO}}_{3},$ ${\mathrm{La}}_{0.7}{\mathrm{Ca}}_{0.3}{\mathrm{MnO}}_{3},$ and
Enhanced far-ultraviolet reflectance of MgF2 and LiF over-coated Al mirrors
This paper presents and discuss data obtained on a distribution of Al+MgF2 and Al+LiF witness coupons that show substantial gains in reflectance in the far-ultraviolet (FUV) part of the optical
Large-aperture wide-bandwidth antireflection-coated silicon lenses for millimeter wavelengths.
An AR coating for curved silicon optics comprised of subwavelength features cut into the lens surface with a custom three-axis silicon dicing saw is presented, and measurements of the optical properties of silicon at millimeter wavelengths at cryogenic and room temperatures are presented.
Hemispherical reflectance and emittance properties of carbon nanotubes coatings at infrared wavelengths
Recent visible wavelength observations of Multiwalled Carbon Nanotubes (MWCNT) coatings have revealed that they represent the blackest materials known in nature with a Total Hemispherical Reflectance
Fast bolometric response by high Tc detectors measured with subnanosecond synchrotron radiation
We have measured a fast response by thin‐film YBa2Cu3O7−δ detectors to pulsed, broadband, infrared radiation. Synchrotron light from an electron storage ring was used as the infrared source,
Angle-of-incidence effects in the spectral performance of the infrared array camera of the Spitzer Space Telescope
The Infrared Array Camera (IRAC) on board the Spitzer Space Telescope uses two dichroic beamsplitters, four interference filters, and four detector arrays to acquire images in four different channels
Exchange interaction effects on the optical properties of LuMnO3.
It is found that the known anomaly in the temperature dependence of the quasistatic dielectric constant epsilon(0) below T(N) approximately 90 K is overwhelmingly dominated by the phonon contributions.
Aluminum mirror coatings for UVOIR telescope optics including the far UV
NASA Cosmic Origins (COR) Program identified the development of high reflectivity mirror coatings for large astronomical telescopes particularly for the far ultra violet (FUV) part of the spectrum as
The CHARIS IFS for high contrast imaging at Subaru
The Coronagraphic High Angular Resolution Imaging Spectrograph (CHARIS) is an integral field spectrograph (IFS) being built for the Subaru telescope. CHARIS will take spectra of brown dwarfs and hot
