We plan to cover all subjects directly related to feedback including stellar and active galact ic nuclei feedback\, interstellar medium\, circumgalactic medium\, mechani cal feedback\, magnetic fields and cosmic rays\, radiative feedback\, etc. from both an observational and theoretical point of view. \nPhotos\nPlea se browse through the photos from the Thinkshop.\nSocial media\nPlease joi n us on Bluesky at #thinkshop2025\nScientific Rationale\nCentaurus A.

How do transformative p rocesses affect the characteristics of galaxies? Observations indicate tha t the mass of a galaxy is a discriminating factor in its ability to effect ively turn gas into stars. But why are galaxies like our own Milky Way app arently the most efficient in producing stars\, while dwarf galaxies and g alaxy clusters struggle? Is "feedback" the answer? and if so\, what is the underlying physics? Or do we need to go beyond Occam's razor and add addi tional interactions to otherwise cold dark matter? What do we know for sur e\, which ideas play most likely an important role and what is pure specul ation about our modern understanding of galaxy formation?\nThe number of o bservational studies of galaxies is rapidly increasing as a consequence of new techniques such as integral field spectroscopy\, and major improvemen ts at radio\, optical\, infrared\, ultraviolet\, X-ray\, and gamma-ray fre quencies. In particular\, recent JWST and MUSE observations have sharpened our understanding of the ISM in nearby galaxies\, the emergence of galact ic winds and opened up new puzzles about the early growth history of galax ies at high redshifts. These observations over the entire electro-magnetic spectrum have allowed astronomers to spatially resolve internal propertie s of galaxies with unprecedented detail\, and are thus providing key insig hts towards understanding the structural components of galaxies\, their st ar-formation processes\, kinematics\, stellar populations\, metal distribu tion\, and nuclear activity\, as well as how galaxies evolve with time. Th ey provide important clues of how cold gas accretes from the circumgalacti c medium (CGM)\, collects in the disk\, is converted into stars and return ed to the CGM in this cosmic cycle of baryons. \nM82.

These simulations can derive insights f rom idealized problem setups of small-scale physics\, including but not li mited to the multi-phase structure of galaxies and plasma physics processe s. Those models are accompanied by simulations that trace galaxy evolution following the hierarchical Lambda cold dark matter scenario with many phy sical processes included\, opening the possibility of performing realistic mock observations and comparisons to observational data. \nThe aim of th e 18th AIP Thinkshop is to bring together leading international experts an d young researchers working in both Galactic and extragalactic astronomy. We aim to discuss the different physical feedback processes shaping galaxi es\, including stellar and AGN feedback\, mechanical feedback\, magnetic f ields and cosmic rays\, radiative feedback\, etc. from both an observation al and theoretical point of view. We will also discuss the interplay of th e different components of a galaxy (stars\, interstellar and circumgalacti c media\, non-thermal components including cosmic rays\, magnetic fields\, and turbulence\, dust\, and dark matter)\, and whether we can find smokin g-gun observables identifying the dominating feedback agents during some s pecific epoch and halo mass range. The final objective is to reach a bette r understanding on the feedback processes that rule the evolution of galax ies. \nTopics\n\nThe role of feedback in self-regulating star formation a nd ISM properties in galaxies\nPhysical properties of gaseous halos and im prints of feedback on them\nCirculation of metals and gas in and out of ga laxies\nObservational evidence for feedback\nTheoretical challenges in mod elling feedback\nGalaxies: stellar feedback\nActive galactic nuclei feedba ck\nFeedback via supernovae\, cosmic rays and radiation\nImpact of cosmolo gical environment on feedback processes\n\n \nPrevious Thinkshop on “Th e role of feedback in galaxy formation”\nAfter the great success of our inaugural Thinkshop on “The role of feedback in galaxy formation” in 2 018\, we would now like to discuss the progress in this exciting and vibra nt field since then.
