Jitter Characterization of the HyTI Satellite
Chase Urasaki, Frances Zhu, Michael Bottom +2
The Hyperspectral Thermal Imager (HyTI) is a technology demonstration mission that will obtain high spatial, spectral, and temporal resolution long-wave infrared images of Earth's…
First tests of a 1 megapixel near-infrared avalanche photodiode array for ultra-low background space astronomy
Charles-Antoine Claveau, Michael Bottom, Shane Jacobson +10
Spectroscopy of Earth-like exoplanets and ultra-faint galaxies are priority science cases for the coming decades. Here, broadband source flux rates are measured in photons per squa…
A Visible-light Lyot Coronagraph for SCExAO/VAMPIRES
Miles Lucas, Michael Bottom, Olivier Guyon +7
We describe the design and initial results from a visible-light Lyot coronagraph for SCExAO/VAMPIRES. The coronagraph is comprised of four hard-edged, partially transmissive focal…
Speckle suppression and companion detection using coherent differential imaging
Michael Bottom, J. Kent Wallace, Randall D. Bartos +2
Residual speckles due to aberrations arising from optical errors after the split between the wavefront sensor and the science camera path are the most significant barriers to imagi…
