Machine Learning for Exoplanet Detection in High-Contrast Spectroscopy: Revealing Exoplanets by Leveraging Hidden Molecular Signatures in Cross-Correlated Spectra with Convolutional Neural Networks
The new generation of observatories and instruments (VLT/ERIS, JWST, ELT) motivate the development of robust methods to detect and characterise faint and close-in exoplanets. Molecular mapping and cross-correlation for spectroscopy […]

Swarming Proxima Centauri: Coherent Picospacecraft Swarms Over Interstellar Distances
Tiny gram-scale interstellar probes pushed by laser light are likely to be the only technology capable of reaching another star this century. We presuppose availability by mid-century of a laser […]

Outback Radio Telescope Listens in on Interstellar Visitor
A telescope in outback Western Australia has been used to listen to a mysterious cigar-shaped object that entered our Solar System late last year. The unusual object–known as ‘Oumuamua–came from […]
