Simultaneous PSF Matching via Dual Kernel Optimization

Abstract Standard point spread function (PSF) matching algorithms consider one image as the reference and aim to find a convolution kernel such that, when applied to the reference image, the PSFs of the reference and non-reference images are matched. This method works well if one...

The Luminosity Function of Ultrafaint Trans-Neptunian Objects Detected by JWST

Abstract We present a definitive discovery of 27 trans-Neptunian objects (TNOs) using the Near-Infrared Camera aboard the James Webb Space Telescope (JWST). By employing a shift-and-stack technique and a machine learning network geared specifically to identifying false-positive d...
