The project is supported by the "Programme to support prospective human resources – post Ph.D. candidates" funded by the Czech Academy of Sciences.

Project goal:
This research project is devoted to the study of new types of solutions in the context of DHOST theories.
Work plan:
Year 1: Construction and study of new black holes solutions in the vector-tensor extension of DHOST theories by using the Kerr-Schild (KS) technique. We expect to find out a sector of quadratic theories admitting non-stealth solutions.
Year 2: Construction of planar black holes in DHOST theories by using axionic scalar fields, together with the study of holographic implications and the thermodynamics of these solutions. Exploring the exact gravitational wave solutions, specifically pp-waves, AdS waves including impulsive waves in DHOST theories. Studying general Kundt metrics and analysis of the corresponding algebraic classification.
