Bayesian multi-band fitting of alerts for kilonovae detection
Biswajit Biswas, Junpeng Lao, Eric Aubourg +4
In the era of multi-messenger astronomy, early classification of photometric alerts from wide-field and high-cadence surveys is a necessity to trigger spectroscopic follow-ups. The…
Neural Posterior Estimation with Differentiable Simulators
Justine Zeghal, François Lanusse, Alexandre Boucaud +2
Simulation-Based Inference (SBI) is a promising Bayesian inference framework that alleviates the need for analytic likelihoods to estimate posterior distributions. Recent advances…
Probabilistic segmentation of overlapping galaxies for large cosmological surveys
Hubert Bretonnière, Alexandre Boucaud, Marc Huertas-Company
Encoder-Decoder networks such as U-Nets have been applied successfully in a wide range of computer vision tasks, especially for image segmentation of different flavours across diff…
Convolution kernels for multi-wavelength imaging
Alexandre Boucaud, Marco Bocchio, Alain Abergel +3
Astrophysical images issued from different instruments and/or spectral bands often require to be processed together, either for fitting or comparison purposes. However each image i…
