A note on the Noether-Wald and generalized Komar charges
Tomás OrtÃn, Matteo Zatti
We propose a simple algorithm to compute the generalized Komar charge of any exactly gauge- and diffeomorphism-invariant theory.

Komar charge of N = 2 supergravity and its superspace generalization
Igor Bandos, Patrick Meessen, Tomás OrtÃn
We find the defining equations for a Killing vector and its superpartner (called the generalized Killing spinor) and use them to construct the generalized Komar superform of minima…

Black hole solutions in theories of supergravity
Tomás OrtÃn
Supergravity has played a very important role in many advances and developments in black hole physics. Here I will review the history of some of them.
