Palatini Linear Attractors Are Back in ACTion
Christian Dioguardi, Alexandros Karam
Recent results from the Atacama Cosmology Telescope (ACT) indicate a scalar spectral index , in excellent agreement with the prediction of linear inflation. Howe…
Fractional attractors in light of the latest ACT observations
Christian Dioguardi, Antonio J. Iovino, Antonio Racioppi
In light of the latest results from ACT observations we review a class of potentials labeled as fractional attractors, that can originate from Palatini gravity. We show that, for c…
Quintessential Inflation in Palatini gravity
Konstantinos Dimopoulos, Christian Dioguardi, Gert Hütsi +1
Palatini gravity, with the inflaton kinetic term, proved to be a powerful framework for generating asymptotically flat inflaton potentials. Here we show that a quadrat…
Natural inflation in Palatini
N. Bostan, R. H. Dejrah, C. Dioguardi +1
In the context of Palatini gravity, models, with X the inflaton kinetic term, are characterized by the appealing property of generating asymptotically flat inflaton potent…
A note on the linear stability of black holes in quadratic gravity
Christian Dioguardi, Massimiliano Rinaldi
Black holes in -gravity are known to be unstable, especially the rotating ones. In particular, an instability develops that looks like the classical black hole bomb mechanism…
