Estimating Probability Densities with Transformer and Denoising Diffusion
Henry W. Leung, Jo Bovy, Joshua S. Speagle
Transformers are often the go-to architecture to build foundation models that ingest a large amount of training data. But these models do not estimate the probability density distr…
Should zeros count? Modeling the galaxy-globular cluster scaling relation with(out) zero-inflated count models
Samantha C. Berek, Gwendolyn M. Eadie, Joshua S. Speagle +1
The scaling relation between the size of a galaxy's globular cluster (GC) population () and the galaxy's stellar mass () is usually described with a continuous, linear…
Stochastic prior for non-parametric star-formation histories
Jenny T. Wan, Sandro Tacchella, Benjamin D. Johnson +3
The amount of power contained in the variations in galaxy star-formation histories (SFHs) across a range of timescales encodes key information about the physical processes which mo…
Katachi: Decoding the Imprints of Past Star Formation on Present Day Morphology in Galaxies with Interpretable CNNs
Juan Pablo Alfonzo, Kartheik G. Iyer, Masayuki Akiyama +8
The physical processes responsible for shaping how galaxies form and quench over time leave imprints on both the spatial (galaxy morphology) and temporal (star formation history; S…
Scaling Laws for Galaxy Images
Mike Walmsley, Micah Bowles, Anna M. M. Scaife +17
We present the first systematic investigation of supervised scaling laws outside of an ImageNet-like context - on images of galaxies. We use 840k galaxy images and over 100M annota…
The Power of High Precision Broadband Photometry: Tracing the Milky Way Density Profile with Blue Horizontal Branch stars in the Dark Energy Survey
Fengqing Yu, Ting S. Li, Joshua S. Speagle +9
Blue Horizontal Branch (BHB) stars, excellent distant tracers for probing the Milky Way's halo density profile, are distinguished in the vs color space from ano…
