Bayesian classification of astronomical spectra with class uncertainties

Simon Barton, Martin Sahlén, Andreas Korn +1

Context: We developed a probabilistic machine learning method with the aim of performing the O(10)-way classification of low- and high-resolution spectra of stellar and extragalact…

Cosmic nucleosynthesis: a multi-messenger challenge

Roland Diehl, Andreas Korn, Bruno Leibundgut +2

The origins of the elements and isotopes of cosmic material is a critical aspect of understanding the evolution of the universe. Nucleosynthesis typically requires physical conditi…

Optimising the shape of photometric redshift distributions with clustering cross-correlations

Benjamin Stölzner, Benjamin Joachimi, Andreas Korn +1

We present an optimisation method for the assignment of photometric galaxies into a chosen set of redshift bins. This is achieved by combining simulated annealing, an optimisation…

Project Hephaistos I. Upper limits on partial Dyson spheres in the Milky Way

Matías Suazo, Erik Zackrisson, Jason T. Wright +2

Dyson spheres are hypothetical megastructures built by advanced extraterrestrial civilizations to harvest radiation energy from stars. Here, we combine optical data from Gaia DR2 w…

Estimating from Gaia low-resolution BP/RP spectra using the ExtraTrees algorithm

Alvin Gavel, René Andrae, Morgan Fouesneau +2

Gaia Data Release 3 will contain more than a billion sources with positions, parallaxes, and proper motions. In addition, for hundreds of millions of stars, it will include low-res…

Forecasting the potential of weak lensing magnification to enhance LSST large-scale structure analyses

Constance Mahony, Maria Cristina Fortuna, Benjamin Joachimi +4

Recent works have shown that weak lensing magnification must be included in upcoming large-scale structure analyses, such as for the Vera C. Rubin Observatory Legacy Survey of Spac…
