Disentangling transients and their host galaxies with Scarlet2: A framework to forward model multi-epoch imaging
Charlotte Ward, Peter Melchior, Matt L. Sampson +6
Many science cases for wide-field time-domain surveys rely on accurate identification and characterization of the galaxies hosting transient and variable objects. In the era of the…

Score-matching neural networks for improved multi-band source separation
Matt L. Sampson, Peter Melchior, Charlotte Ward +1
We present the implementation of a score-matching neural network that represents a data-driven prior for non-parametric galaxy morphologies. The gradients of this prior can be inco…
