Point spread function subtraction using telemetry data: one more step on the path to reaching the photon-noise limit in high-contrast imaging

Current HCI systems are limited by residual starlight, resulting from atmospheric turbulence unseen by the adaptive optics system or stemming from imperfections in the optical system itself. This leads to speckles in the PSF of the final images inhibiting our detection capabilities. Reaching the photon-noise limit in h...
