Hot off the press! Via the magic of differentiable forward modeling and of non-redundant masking on JWST we may have found a new exoplanet!
One of the most challenging papers I've written, but I'm glad its finally out!

A Candidate Innermost Fifth Planet In the HR 8799 System Revealed By JWST NIRISS Aperture Masking Interferometry
We detect a candidate fifth planet in the HR 8799 system, directly imaged with the JWST/NIRISS Aperture Masking Interferometer (AMI). The detected source lies just above a $3σ$ contrast curve at a con...
