    1. 4. Rainbow: a colorful approach on multi-passband light curve estimation
      Etienne Russeil
      1/8/24, 11:00 AM

      Rainbow is a physically motivated framework which enables simultaneous multi-band light curve fitting. It allows the user to construct a 2-dimensional continuous surface across wavelength and time, even in situations where the number of observations in each filter is significantly limited. Assuming the electromagnetic radiation emission from the transient can be approximated by a black-body,...

    4. 5. Multiview Symbolic Regression in astronomy
      Etienne Russeil
      1/8/24, 3:00 PM

      Symbolic Regression is a data-driven method that searches the space of mathematical equations with the goal of finding the best analytical representation of a given dataset. It is a very powerful tool, which enables the emergence of underlying behavior governing the data generation process. Furthermore, in the case of physical equations, obtaining an analytical form adds a layer of...

    5. 1. Anomaly detection in Fink
      Maria Pruzhinskaya (LPC)
      1/9/24, 9:00 AM

      I would like to talk about recent updates on Fink AD module, including our last discoveries ZTF23aalftv and AT2023awt, their spectroscopic and photometric follow-up.

    6. 7. Deep dive into asteroid colors and spins in LSST era
      Dr Benoit Carry (Lagrange, Observatoire de la Cote d Azur)
      1/9/24, 11:00 AM

      With the advent of large-scale photometric surveys such as the ZTF and the Rubin Observatory, millions of Solar System objects (SSOs) are surveyed every night. The irregular cadence of these surveys precludes a simple determination of the colors of SSOs, whose photometry constantly varies due to their irregular shape and the ever changing Sun-SSO-Earth geometry.

      We extended the phase...

    7. 8. Desmitifying Fink
      Adrien RAMPARISON (CNRS), Dr Julien Peloton (CNRS-IJCLab)
      1/9/24, 2:00 PM
    8. 2. Enhancing the Infrastructure of Fink Project: A Kubernetes-based Approach
      Fabrice Jammes (CNRS)
      1/9/24, 3:00 PM

      This talk will present a summary of recent activities within Fink, an alert broker research platform. The primary focus of this contribution has been on preparing the production environment using Kubernetes as the target platform.

      Software Stack Packaging

      The initial goal was to package the entire software stack of Fink. This involved packaging key components (fink-broker,...

    10. 6. Enhancing neutrino alerts for KM3NeT with multi-wavelength correlation
      Godefroy Vannoye
      1/10/24, 9:00 AM

      The study of celestial transient objects relies on the coordination of different observations. As an increasing number of actors join this coordination, the number of alerts grows rapidly, and each experiment needs to maximize the scientific interest of their public alerts.

      KM3NeT is a neutrino telescope consisting of two detectors, ORCA and ARCA, currently under deployment in the...
