abstract
The Planetary Camera and Spectrograph (PCS) for the Extremely Large Telescope (ELT) will be dedicated to detecting and characterising nearby exoplanets with sizes from sub-Neptune to Earth-size in the neighbourhood of the Sun. This goal is achieved by a combination of eXtreme Adaptive Optics (XAO), coronagraphy and spectroscopy. PCS will allow us not only to take images, but also to look for biosignatures such as molecular oxygen in the exoplanets' atmospheres. This article describes the PCS primary science goals, the instrument concept and the research and development activities that will be carried out over the coming years.

Differentiable design of the PIAA-ZWFS: a flexible wavefront sensor that approaches the fundamental limit
The PIAA-ZWFS, optimized with differentiable modeling and Bayesian design, closes the gap to the fundamental wavefront sensing limit by a factor of 10 versus conventional ZWFS in photon-limited simulations.
