This talk explores how astronomers reconstruct black hole environments using X-ray polarization while reflecting on the fragility of telescopes, scientific archives, and human memory. It connects astrophysical discovery with the preservation of historical records, highlighting the overlooked contributions of women astronomers and the importance of safeguarding scientific heritage.

This research uses weak gravitational lensing to map the invisible distribution of dark matter within galaxy clusters. By measuring tiny distortions in the shapes of distant galaxies, it reconstructs total mass distributions, helping scientists understand dark matter, galaxy cluster evolution, and the large-scale structure and history of the universe.

This research uses gravitational lensing to investigate dark matter, the invisible substance that makes up roughly 80% of the Universe's matter. By studying distortions in light caused by massive galaxies, it seeks to identify dark matter structures and determine whether dark matter is clumpy, smooth, cold, warm, concentrated, or diffuse.
