178. [INVITED] Building Robust and Impactful Machine Learning Models in Astronomy

Daniela Huppenkothen

Oral Presentation

Machine learning has rapidly become a tool of choice for the astronomical community. It is being applied across a wide range of wavelengths and problems, from the classification of transients to neural network emulators of cosmological simulations, and is shifting paradigms about how we generate and report scientific results. At the same time, this class of method comes with its own set of...

182. Neural network for improving the flux density estimations in polarization of compact sources.

The importance of galaxy clusters and extra-galactic sources seen as compact or point sources (PS) in ground- and space-based CMB experiments has been clear since the conception of the Wilkinson Microwave Anisotropy Probe and Planck missions. PS in the microwave regime are mainly blazars that affects recovery of the CMB anisotropy signal especially at small angular scales. Unresolved polarized...

179. Deep learning tools for detecting and segmenting galactic structures and contaminants in low surface brightness images

Oral Presentation

The diffuse tidal stellar features that surround galaxies bring a testimony on past galaxy collisions. Because of their low surface brightness and the presence of multiple image contaminants, they are particularly difficult to isolate with classical IA techniques. We present new deep learning techniques to finely characterise the morphology of galaxies from large datasets of deep optical...

181. Detection of Galaxy Tidal Features using Self-Supervised Machine Learning

Oral Presentation

Low surface brightness substructures around galaxies are a valuable tool in the detection of past or ongoing galaxy mergers. The properties of these substructures, along with the properties of their host galaxy, can tell us about a galaxy’s past interactions and the evolution of galaxy populations. In order to draw accurate and statistically robust conclusions about this evolution process, we...
