Differentiable Optics with dLux II: Optical Design Maximising Fisher Information

The design of astronomical hardware operating at the diffraction limit requires optimisation of physical optical simulations of the instrument with respect to desired figures of merit, such as photometric or astrometric precision. System design entails many parameters some of whi...

Photometry for highly saturated TESS stars

Saturation in TESS complicates simple aperture photometry, as flux can be lost to bleeding outside the target pixels. Halo photometry can nevertheless reconstruct good light curves of these stars, as a weighted linear combination of pixel time series from the unsaturatedwings of...
