The role of the in flaton is played by a blowup modulus of a type IIB Calabi-Yau compactifica tion. I will start by recalling that\, in the Large Volume Scenario of mod uli stabilization\, such a modulus can remain unstabilized at leading orde r. This observation has given rise to the proposal of Blowup Inflation. Ho wever\, as I will explain\, loop corrections are generically present and t oo large to allow for slow roll. Our proposal employs this setting in a ne w regime\, where the value of the blowup modulus is much larger and slow-r oll can hence be realized. A detailed analysis\, based on the explicitly k nown form of loop corrections in this specific geometry\, reveals that obs ervational and consistency constraints can be met and interesting predicti ons for inflationary and late-time cosmological observables are possible.\ n LOCATION:https://researchseminars.org/talk/AnLy/42/ END:VEVENT END:VCALENDAR
