Bergshoeff, E. A., Hartong, J., Ploegh, A., Sorokin, D.
We construct the half-supersymmetric instanton solutions that are electric-magnetically dual to the recently discussed half-supersymmetric Q7-branes. We call these instantons `Q-instantons'. Whereas...

Q-branes in type IIB supergravity (2008)
Bergshoeff, E.A., Hartong, J., Sorokin, D.
The notion of Q7-branes and Q-instantons is introduced. These are one-half BPS solutions of the type IIB supergravity theory characterized by a set of three parameters p, q, r such that r^2 > 4pq....
Pseudo-supersymmetry and a Tale of Alternate Realities (2007)
Bergshoeff, E. A., Hartong, J., Ploegh, A., Rosseel, J., Bleeken, D. Van Den
We discuss how all variant 10d and 11d maximal supergravities, including star supergravities and supergravities in different signatures, can be obtained as different real slices of three complex...
IIB seven-branes revisited (2007)
Ortín, T., Hartong, J., Bergshoeff, E., Roest, D.
We re-investigate the construction of half-supersymmetric seven-brane solutions of IIB supergavity. In contrast to previous approaches we allow the occurrence of objects with monodromy Tr Λ ≠ 2....
