Liouville strings in AdS: the worldsheet story
Gaston Giribet, Pedro Schmied
The worldsheet -model of strings on AdS with NS-NS fluxes can be equivalently described in terms of a Liouville field theory coupled to a timelike field with background char…
Neural-Spectral Discovery of Rotating Black Holes Beyond General Relativity
Felipe Agurto-Sepúlveda, Marcelo Oyarzo, Anxo Biasi +6
Finding rotating black hole solutions in higher-curvature theories of gravity is a problem of fundamental importance. Virtually every approach to reconcile gravity with quantum mec…
Higher-curvature corrections and near horizon symmetries
Mariano Chernicoff, Gaston Giribet, Julio Oliva
In the near-horizon region, black holes exhibit an infinite-dimensional symmetry reminiscent of the Bondi-Metzner-Sachs (BMS) supertranslations. The conserved charges associated wi…
Exploring the Kleinian horizons
Gaston Giribet, Juan Laurnagaray, Bryan Malpartida +1
Self-dual black holes in (2,2) signature spacetime -- Klein space -- have recently attracted interest in the context of celestial holography. Motivated by this development, we inve…
Celestial closed strings at one-loop
Anthonny F. Canazas Garay, Gaston Giribet, Yoel Parra-Cisterna +1
In this paper we continue our investigation of superstring scattering amplitudes in the conformal basis. We focus on the case of four graviton scattering processes at 1-loop in \em…
Revisiting a family of five-dimensional charged, rotating black holes
Marcos R. A. Arcodía, Gaston Giribet, Juan Laurnagaray
In the absence of a higher-dimensional analogue to the Kerr-Newman black hole, 5-dimensional Einstein-Maxwell theory with a Chern-Simons term has become a natural setting for study…
