RUBIX: Differentiable forward modelling of galaxy spectral data cubes for gradient-based parameter estimation
Anna Lena Schaible, Ufuk Ãakır, Tobias Buck +5
Although integral-field spectroscopy enables spatially resolved spectral studies of galaxies, bridging particle-based simulations to observations remains slow and non-differentiabl…
Causal Discovery of Latent Variables in Galactic Archaeology
Zehao Jin, Yuxi Lu, Yuan-Sen Ting +2
Galactic archaeology--the study of stellar migration histories--provides insights into galaxy formation and evolution. However, establishing causal relationships between observable…
Fast GPU-Powered and Auto-Differentiable Forward Modeling of IFU Data Cubes
Ufuk Ãakır, Anna Lena Schaible, Tobias Buck
We present RUBIX, a fully tested, well-documented, and modular Open Source tool developed in JAX, designed to forward model IFU cubes of galaxies from cosmological hydrodynamical s…
Deep Multimodal Representation Learning for Stellar Spectra
Tobias Buck, Christian Schwarz
Recently, contrastive learning (CL), a technique most prominently used in natural language and computer vision, has been used to train informative representation spaces for galaxy…
