X-ray Astronomy emerged in the early 1960s, and it quickly became evident that X-ray polarimetry would be crucial for interpreting data from celestial sources discovered thereafter. However, the experimental results from those early attempts were limited. On one hand, the sources were less polarized than expected; on the other, the sensitivity of the experimental techniques was still...

The launch of the Imaging X-ray Polarimetry Explorer (IXPE) in Dec 2021 opened a new era in the study of compact astrophysical objects. For unresolved sources, polarimetry is the only way to learn about the source geometry. In this talk, I will highlight the progress made thanks to IXPE in understanding the geometry and physics of emitting regions in accreting black holes and neutron stars.

The advent of gravitational wave astronomy has fundamentally changed our view of Black Holes, as far as their demographics are concerned. Likewise, the VLBI submm interferometric observations have finally directly shown us the relativistic distortions of spacetime close to a Black Hole. We may also detect neutrinos from extragalactic sources. I will argue that these novel observations nicely...
