Abstract
We present progress towards developing a science-grade, megapixel format linear-mode avalanche photodiode array for low background shortwave (1 - 2.4 um) infrared astronomy. Our latest results show outstanding performance, with dark current <1e-4 electrons/pixel/second and read noise reducing by 30% per volt of bias, reaching less than 1e-/pixel/frame in correlated double-sampling, and able to average down to ~0.3 e-/pixel/frame when using multiple non-destructive reads. We present some on-sky data as well as comment on prospects for photon counting and photon number resolution.
