A machine learning approach for computing solar flare locations in X-rays on-board Solar Orbiter/STIX

Autor: Massa, Paolo, Felix, Simon, Etesi, László István, Dickson, Ewan C. M., Xiao, Hualin, Ramunno, Francesco P., Selcuk-Simsek, Merve, Panos, Brandon, Csillaghy, André, Krucker, Säm

The Spectrometer/Telescope for Imaging X-rays (STIX) on-board the ESA Solar Orbiter mission retrieves the coordinates of solar flare locations by means of a specific sub-collimator, named the Coarse Flare Locator (CFL). When a solar flare occurs on t

Magnetogram-to-Magnetogram: Generative Forecasting of Solar Evolution

Autor: Ramunno, Francesco Pio, Jeong, Hyun-Jin, Hackstein, Stefan, Csillaghy, André, Voloshynovskiy, Svyatoslav, Georgoulis, Manolis K.

Investigating the solar magnetic field is crucial to understand the physical processes in the solar interior as well as their effects on the interplanetary environment. We introduce a novel method to predict the evolution of the solar line-of-sight (

STIX X-ray microflare observations during the Solar Orbiter commissioning phase

Publikováno v: A&A 656, A4 (2021)

The Spectrometer/Telescope for Imaging X-rays (STIX) is the HXR instrument onboard Solar Orbiter designed to observe solar flares over a broad range of flare sizes, between 4-150 keV. We report the first STIX observations of microflares recorded duri

CosmoHammer: Cosmological parameter estimation with the MCMC Hammer

Autor: Akeret, Joël, Seehars, Sebastian, Amara, Adam, Refregier, Alexandre, Csillaghy, André

Publikováno v: Astronomy and Computing, Volume 2, August 2013, Pages 27-39

We study the benefits and limits of parallelised Markov chain Monte Carlo (MCMC) sampling in cosmology. MCMC methods are widely used for the estimation of cosmological parameters from a given set of observations and are typically based on the Metropo

Automation of the filament tracking in the framework of the HELIO project

Autor: Bonnin, Xavier, Aboudarham, Jean, Fuller, Nicolas, Csillaghy, Andre, Bentley, Robert D.

We present a new method to automatically track filaments over the solar disk. The filaments are first detected on Meudon Spectroheliograph H{\alpha} images of the Sun, applying the technique developed by Fuller, Aboudarham, and Bentley (Solar phys. 2

The flare likelihood and region eruption forecasting (FLARECAST) project: flare forecasting in the big data & machine learning era

Publikováno v: Journal of Space Weather and Space Climate, Vol 11, p 39 (2021)

The European Union funded the FLARECAST project, that ran from January 2015 until February 2018. FLARECAST had a research-to-operations (R2O) focus, and accordingly introduced several innovations into the discipline of solar flare forecasting. FLAREC
