Recent advances in large-scale structure (LSS) theory have opened up new avenues for probing fundamental physics with the cosmic web. Future galaxy surveys will soon map the Universe with unprecedented sub-percent precision. I will present tools...

We discuss the possible transition between string scale black holes and self gravitating fundamental strings. We find evidence for a smooth transition in the heterotic string case while in the type II case they cannot be connected as classical...

The Gaia mission and its data releases are driving a revolution in our understanding of the Milky Way and its constituents. In this talk, I will highlight a few of the results stemming from the analysis of the truly spectacular datasets produced so...

The operator product expansion of massless celestial primary operators of arbitrary spin is investigated.  Poincare symmetry is found to imply a set of recursion relations on the operator product expansion coefficients of the leading singular terms...

I will review some interesting features regarding the spectrum of near-extremal black holes in gravity and near-BPS black holes in supergravity, which are derived from the Euclidean path integral. For simplicity, I will focus on the case of charged...

In the Solar system, the planets follow orbits that are nearly aligned with the Sun's equatorial plane. What about planets around other stars? Many techniques are available to measure the obliquities of planet-hosting stars, ranging from an effect...
