BOWIE-ALIGN: A JWST comparative survey of aligned vs misaligned hot Jupiters to test the dependence of atmospheric composition on migration history
(Oxford University Press (OUP) / Royal Astronomical Society, 10 October 2024)A primary objective of exoplanet atmosphere characterisation is to learn about planet formation and evolution, however, this is challenged by degeneracies. To determine whether differences in atmospheric composition can ... -
An absolute mass, precise age, and hints of planetary winds for WASP-121 A and b from a JWST NIRSpec phase curve
(American Astronomical Society / IOP Publishing, 1 November 2024)We have conducted a planetary radial velocity measurement of the ultrahot Jupiter WASP-121b using JWST NIRSpec phase curve data. Our analysis reveals the Doppler shift of the planetary spectral lines across the full orbit, ... -
Imaging through scattering media by exploiting the optical memory effect: a tutorial
(IOP Publishing, 18 September 2024)Scattering, especially multiple scattering, is a well known problem in imaging, ranging from astronomy to medicine. In particular it is often desirable to be able to perform non-invasive imaging through turbid and/or opaque ... -
Protocols for trainable and differentiable quantum generative modeling
(American Physical Society (APS), 12 September 2024)We propose an approach for learning probability distributions as differentiable quantum circuits (DQC) that enable efficient quantum generative modeling (QGM) and synthetic data generation. Contrary to existing QGM approaches, ... -
Rapid terahertz beam profiling and antenna characterization with phase-shifting holography
(Nature Research, 10 September 2024)In this paper we investigate the application of phase-shifting digital holography for the real-time characterization of electromagnetic sources in the THz frequency range. We use an of-the-shelf terahertz detector array ...
