Collective Astronomy: Lessons from Extreme Galaxy Encounters and Dark Matter Studies

Explore a thought-provoking colloquium talk that delves into the fascinating discovery of dark matter-deficient galaxies and their implications for our understanding of the cosmos. Learn how extreme galactic encounters can naturally produce these unique celestial objects within the standard cosmological model, supported by evidence from the cutting-edge FIREbox simulation. Discover how tidal stripping and star formation processes operate under extreme conditions, while also examining the intersection of astronomy with broader cultural and social perspectives. Gain insights into innovative concepts like pachamama and astromimicry, which form the foundation of collective astronomy - an approach aimed at fostering more inclusive and welcoming scientific communities. Through this comprehensive presentation, understand both the technical aspects of galaxy evolution and the importance of creating diverse, collaborative spaces in astronomical research.
