We survey on-shell and off-shell higher derivative supergravities in dimensions 1≤ D≤ 11.
Various approaches to their construction, including the Noether procedure,(harmonic) …

A bstract The scale at which quantum gravity becomes manifest, the species scale Λ s, has
recently been argued to take values parametrically lower than the Planck scale. We use …

We present a complete basis to study gauged curvature-squared supergravity in five
dimensions. We replace the conventional ungauged Riemann-squared action with a new …

A bstract We study supersymmetric AdS 2× Y 9 solutions of 11d supergravity where Y 9 is an
S 7 fibration over a Riemann surface equipped with a metric of non-constant curvature. We …

We study four-derivative corrections to four-dimensional N= 2 minimal gauged supergravity
controlled by two real constants. The solutions of the equations of motion in the two …

A bstract We use conformal supergravity techniques to study four-derivative corrections in
four-dimensional gauged supergravity. We show that the four-derivative Lagrangian for the …

A bstract We find new asymptotically locally AdS 4 Euclidean supersymmetric solutions of
the STU model in four-dimensional gauged supergravity. These “black saddles” have an S …

A bstract We study the parameter space of magnetically charged AdS 2×\({\mathbbm {WCP}}
_ {\left [{n} _ {-}{n} _ {+}\right]}^ 1\) solutions in 4d U (1) 4 gauged STU supergravity. We show …

A bstract Small black holes are a powerful tool to explore infinite distances in moduli spaces.
However, we show that in 4d theories with a scalar potential growing fast enough at infinity …

A bstract We analyse the scalar curvature of the vector multiplet moduli space\({\mathcal {M}}
_X^{\textrm {VM}}\) of type IIA string theory compactified on a Calabi-Yau manifold X. While …
