- Static, spherically symmetric vacuum solutions to quadratic gravity
*Dr. Alena Pravdová, Dr. Vojtěch Pravda*- Department of Algebra, Geometry and Mathematical Physics, Institute of Mathematics, Czech Academy of Sciences
We present several classes of static, spherically symmetric vacuum solutions to quadratic gravity. Notably, besides the Schwarzschild black hole, these solutions also contain a static, spherically symmetric black hole with non-trivial Ricci tensor.

- Systematic tests of dark matter and modified gravity
*Dr. Ivan de Martino*- Donostia International Physics Center, Donostia-San Sebastian, Spain
The standard cosmological model has been constrained with unprecedented accuracy. Nevertheless, we are facing off new challenges. The lack of detection of Dark Matter and Dark Energy have opened to new paths. On one side, we are entering the "no-WIMP" era. On the other side, explaining the accelerated expansion of the Universe may require an extension of General Relativity. I will review the state of art of the standard cosmology while introducing new tests of both Dark Matter and Modified Gravity. I will introduce a relatively new paradigm for Dark Matter, named Ultra-light axions, and explain how to probe it with the current and forthcoming dataset. Then, I will also show some tests of the standard cosmological model and of modified gravity that near in future may be helpful to constrain/rule out models.
