Topological Signatures of AGN Feedback in the Simba Simulations
Ryusei R. Kano, Romeel Davé, Tsutomu T. Takeuchi +1
Active galactic nuclei (AGN) feedback can alter the abundance and spatial distribution of galaxies within large-scale structure. We apply topological data analysis (TDA) to Simba h…

Resolving the Dust Budget Crisis at with Optically Thick, High-Density Molecular Clumps: MACS0416_Y1
Ryusei R. Kano, Tsutomu T. Takeuchi, Erina R. Kawamoto +3
Dust plays a crucial role in galaxy evolution by shaping the spectral energy distribution (SED) and star formation history. However, standard models often underestimate the infrare…

Joint State-and-Dynamics Inference for Galaxy Population Evolution on an Effective Manifold
Tsutomu T. Takeuchi, Ryusei R. Kano
Galaxy surveys provide noisy, incomplete, selection-affected population snapshots rather than complete evolutionary histories. We formulate galaxy evolution as joint inference of e…
