Generalized quasitopological gravities (GQTGs) are higher-order extensions of Einstein
gravity in D dimensions satisfying a number of interesting properties, such as possessing …

We construct slowly rotating black-hole solutions of Einsteinian cubic gravity (ECG) in four
dimensions with flat and anti–de Sitter asymptotes. At leading order in the rotation …

Generalized quasi-topological gravities (GQTGs) are higher-curvature extensions of Einstein
gravity in D-dimensions. Their defining properties include possessing second-order …

In this note we revisit the analysis performed in De Felice and Tsujikawa (2023 Phys. Lett. B
843 138047) of odd-parity perturbations around static and spherically symmetric black holes …

We revisit the recently proposed mechanism of Geometric Inflation. On general grounds, we
show that obtaining the right amount of inflation demands an exceedingly large initial energy …

A new cosmological theory is proposed in the theoretical framework of modified gravity
theories which is based on a tachyonic field non-minimally coupled with a specific …

Cosmological and thermodynamic implications of non-canonical scalar field are investigated
in the cubic gravity by assuming various parameterizations (linear, Chevallier-Polarski …

We investigate sufficient conditions under which cubic gravity is healthy and viable at the
perturbation level. We perform a detailed analysis of the scalar and tensor perturbations. We …

The paper studies different observational features in the case of a specific cubic gravity
theory, based on third order contractions of the Riemann tensor. Considering viable cosmic …

We put forward novel extensions of Starobinsky inflation, involving a class of “geometric”
higher-curvature corrections that yield second-order Friedmann-Lemaître equations and …
