PublicaciónThe PAU Survey and Euclid: Improving broadband photometric redshifts with multi-task learning
Current and future imaging surveys require photometric redshifts (photo-zs) to be estimated for millions of galaxies. Improving the photo-z quality is a major...

PublicaciónThe Photo-Astrometric vertical tracer density of the Milky Way - I. The method
We introduce a method to infer the vertical distribution of stars in the Milky Way using a Poisson likelihood function, with a view to applying our method to...
