For the next few days we have the pleasure of hosting Anjan Sen (who already visited us two years ago) and Antonio Junior Iovino, visiting us from Jamia Millia Islamia and NYU Abu Dhabi respectively. They will be giving us two talks respectively on an innovative way of measuring the low-redshift expansion rate and constrain the physics of Dark Energy at characteristic redshifts, and on recent important developments in primordial black hole physics. Welcome Anjan and Antonio!
