School of Statistics for Astrophysics 2019: Variability and Time Series Analysis
Oct 6 – Oct 12 all-day

Annonce en lien avec l’Action/le Réseau : MAESTRO

Thème :

Astrostatistics

Présentation :

The topic of the 2019 session of Stat4Astro is the time series (including variabilities and transient events) that, from celestial mechanics to gravitational waves, from exoplanets to quasars, concern nearly all the astrophysics. Variable phenomena are ubiquitous in the Universe: periodic (orbits, cycles, pulses, rotations…), transient (explosions, bursts, stellar activity…), random (accretion, ejection…) or regular (apparent motions…). The detection, the characterization and the classification of these variabilities is a discipline of statistics called time series analysis. In astrophysics, the detection can be immediate to alert other telescopes, or very detailed to identify some exoplanets or probe the interior of stars. The characterization is required for the physical modeling and understanding. Classification is of course necessary to organize the observations.

journées en analyse et traitement d’images astronomiques
Jan 24 – Jan 26 all-day

Annonce en lien avec l’Action/le Réseau : MAESTRO

Thème :

Traitement d’image en astrophysique

Présentation :

Nous organisons les 24 et 25 janvier 2019 à Strasbourg deux journées scientifiques sur le traitement d’images astronomiques. Ces deux journées seront ouvertes aux chercheurs en traitement d’images ainsi qu’aux astronomes, l’idée principale étant de stimuler les discussions entre ces deux disciplines sans se restreindre à une problématique ou un instrument. L’objectif de ces journées est double. Tout d’abord, elles permettront de faire le point sur les recherches actuelles et les problèmes ouverts, qu’ils soient actuels ou pressentis. Ensuite, elles favoriseront les échanges entre les deux communautés, de façon à réfléchir aux verrous existants et à préparer la résolution des problèmes ouverts.

Mining the sky: knowledge discovery in big and complex astronomical data sets and data streams @ Athens
Dec 6 – Dec 9 all-day

Astronomical observations produce some of the largest “big data” today through a new generation of telescopes. While these data sets exhibit the usual challenges associated with big data (immense data volumes, high dimensionality, high complexity, disparate variables, etc.) there are new problems such as pattern discovery from low-signal-to-noise imagery, near-real-time classification of multi-terabyte-size data, and the presence of strict laws of physics behind the data production which can often be assimilated into machine learning. This Special Session at a large IEEE Computational Intelligence meeting aims to engage the computational community in solutions to problems modern astronomy faces.

ICCUB School Machine Learning and Data Mining in Physics @ Institute of Cosmos Sciences, Barcelona
Oct 17 – Oct 21 all-day

This school is addressed to doctorates and post-docs working in astrophysics or particle physics, with special emphasis on those working on LHCb, Belle II, Gaia, CTA or MAGIC.

The School will be structured around two Kaggle-challenge-like projects, one in the domain of particle physics and one in astrophysics which highlight the two big groups of Machine Learning and Data Mining techniques: classification and separation. With around 5-6 hours of lessons per day, the basics of these techniques will be covered, both from the theoretical and from the practical (hands-on) point of view. Two pieces of software, covering most needs, will be introduced and students will be free to use any of them for tackling the projects. Additional time will be devoted to covering some other innovative techniques.

Journées de l’Action MAESTRO

Présentation :

Dans le domaine de l’astronomie, l’évolution rapide des télescopes et autres instruments scientifiques ainsi que le recours intensif à la simulation informatique ont conduit, ces dernières années, à une production massive de données.

De plus l’Astrophysique doit aborder des problématiques de probabilités et statistiques dans le domaine de l’acquisition ou du traitement de données, de l’analyse et de l’exploitation (validation de modèles, problèmes inverses mal contraints, réduction de dimensionnalité, classifications, fouille de données, …).

Cette première réunion MAESTRO a pour but de mettre en contact les spécialistes d’astrophysique ainsi que les différents spécialistes en traitement de données, en stockage, mise à disposition et visualisation de données. Ces deux journées s’organiseront de manière à présenter les activités des laboratoires et équipes sur des réalisations astrophysiques et informatiques. Une partie des journées sera aussi dédiée à des discussions permettant un rapprochement des communautés.

COSMO21 @ Chania - Grece
May 24 – May 27 all-day

During the past 20 years there has been a resumption of a dialogue between astronomers and statisticians. This dialogue has been fruitful and has been the origin of a new discipline that is now widely called Astrostatistics. The main tools for comparing theoretical results with observations in astronomy are statistical. However, the development of huge astronomical databases presents challenges of scale, and has initiated an active use of newly-developed statistical techniques in astronomy, notable examples being sparsity and compressed sensing.

The meeting is especially timely from the point of view of cosmological surveys, where the size makes application of a fully Bayesian analysis computationally extremely demanding, especially in the realm of model selection. Pan-STARRS will have a complete survey of 3π steradians of petabyte size; the Dark Energy Survey and the VST KiDS surveys will be well underway presenting similar difficulties in the data analysis. Moreover, the cosmological community will be preparing for LSST and for Euclid, a survey of a large fraction of the sky at an angular resolution close to that of the Hubble Space Telescope. Wide-field spectroscopic cosmology surveys of will be targeting over 10 million objects with a spectral resolution of 5000, with the SKA precursors will be grappling with data challenges which currently are unsolved. These examples also highlight the big current role and even bigger future role of archival data in astrophysics research.

This meeting offers an opportunity to show-case techniques and methodologies that will have to be used by the wider community to use these archival data.

ADA8 @ Chania Grece
May 22 – May 24 all-day

Held regularly since 2001, the ADA – Astronomical Data Analysis – conference series has been focused on algorithms and information extraction from astrophysics data sets. It became a strongly interdisciplinary forum where researchers from diverse fields such as Astronomy, Statistics, Mathematics and Computing could interact. This conference series has been characterized by a range of innovative themes, including multi-scale geometric transforms such as the curvelet transform, compressed sensing and clustering, always remaining closely linked to front-line open problems and issues in Astronomy.

Along many of its editions, the ADA conference series included hands-on tutorial sessions on various topics of advanced data processing. In the era of large astronomical surveys that are grappling with unsolved methodological and data challenges, transforming Data into Science is a huge, and exciting, problem, and a large fraction of modern Astronomy depends on this. Nevertheless, postgraduate courses can hardly cope with the pace of development of the modern data analysis methods and tools that may enable researchers to make the best use of their data. This is the main focus of the ADA8 2016 Summer School: to present advanced data analysis methods and algorithms and to demonstrate how to use publicly available codes to improve knowledge extraction from astronomical datasets, enabling a better Science.

These tutorials are not intended exclusively for an audience with background in Astrononomy, and are aimed mainly aimed for young researchers at MSc, PhD and postdoc levels, albeit any researchers are welcome to attend. Moreover, this year ADA will take place on the days preceding the COSMO21 conference, both event take place at the same venue and the inscription in COSMO21 includes the possibility to participate in the ADA8 Summer School.
