Planck-selected strongly lensed high-redshift galaxies: systematic search, in Planck catalogues and maps, for ultra-bright, strongly lensed dusty star-forming galaxies (DSFGs); physical characterisation (redshift, gas and dust mass, star-formation rate) and lens modelling through sub-millimetre and radio follow-up observations (NOEMA, NIKA2, SCUBA-2, ATCA, EVN+e-MERLIN).
Weak-lensing detection of galaxy clusters: development and application of the optimal-filtering algorithm AMICO-WL to identify clusters in shear maps; validation on simulations and application to Euclid data (Galaxy Clusters SWG).
Lensed sub-millimetre galaxies in Euclid: identification and study of strongly lensed sub-millimetre galaxies in the Euclid releases (Q1, DR1), in synergy with sub-millimetre and radio surveys (Herschel, SCUBA-2, MIGHTEE, LOFAR), within the Strong Lensing SWG.
Radio astronomy and interferometry: high-resolution interferometric observations (VLBI with EVN+e-MERLIN, NOEMA, ATCA, LOFAR) of lensed systems; radio morphology and nature of the emission (star formation or AGN) in lensed sources and in lens galaxies.
