PublicationThe elusive atmosphere of WASP-12 b. High-resolution transmission spectroscopy with CARMENES
To date, the hot Jupiter WASP-12 b has been the only planet with confirmed orbital decay. The late F-type host star has been hypothesized to be surrounded by a...

PublicationThe entropy of galaxy spectra: how much information is encoded?
The inverse problem of extracting the stellar population content of galaxy spectra is analysed here from a basic standpoint based on information theory. By...
