TL;DR

This paper constructs a string theory realization of warped AdS3 geometries from brane configurations, explores their supersymmetry, and introduces a new warped black hole solution with thermodynamic analysis.

Contribution

It provides explicit supergravity solutions with warped AdS3 geometries from TsT transformations, including their supersymmetry properties and a novel warped black hole.

Findings

Solutions preserve four supercharges.

Near-horizon geometries are explicitly constructed.

A new doubly-deformed warped black hole solution is presented.

Abstract

We provide a string theory realisation of a two-parameter family of Type IIB supergravity solutions of the form ${\rm WAdS}_3 \times {\rm WS}^3 \times M_4$, as near-horizon geometries of supersymmetric backgrounds involving D1-D5 branes, D3-branes and NS5-branes. We show that the full solutions, as well as their near-horizon limits, preserve four supercharges. We end by presenting a new doubly-deformed warped black hole solution and study its thermodynamical properties.
