Workshop on Open-Source Software Lifecycles

23 juil. 2020, 09:00 → 28 juil. 2020, 12:25 Europe/Paris

https://fau.zoom.us/j/92142605646 (ZOOM)

Software development is an integral part of modern science, gaining knowledge from data. All ESCAPE partners develop and maintain some software (from extensive frameworks to individual analysis scripts) for their respective experiments - along the full life cycle of software development.

The objective of this workshop is to bring together the scientists' communities of Astrophysics, Astroparticle Physics and Particle Physics who are leading the software development within their domain. Common and best practices in software development will be discussed and shared, enabling cross-fertilization across the domains. Those practices will then be taken into account in the upcoming ESCAPE school, training young scientists to build and maintain the expertise in the field

Core topics are:

• Software Development Lifecycle Strategies
• Development: coding styles, versioning, maintenance, documentation, software quality standards
• Testing: test suites and code coverage
• efficiency optimization and benchmarking: standards and ideas
• platform integration and metadata
• software licenses

10:15 SKA Software Development: Scaling agile software development processes around the world

The Square Kilometre Array Organisation (SKAO) is in the process to start construction of what will be the largest research facility in the world, with two radio interferometers generating each one petabyte of data per day, which will be distributed by a network of SKA Regional Centres (SRCs). Construction is expected to start after the establishment of the SKA Observatory Inter-Governmental Organisation by mid 2021, and last for around 6 years after that. However, we are already prototyping the software development processes that will help us align the work of around 150 full-time equivalent people around the world. In this talk we will show what are the current agile software development processes at SKAO, how we are already leveraging the Scaled Agile Framework (SAFe®) to provide alignment across the world-wide community of developers and other contributors, and how we will be managing the full software lifecycle of it during construction and beyond.

10:05 agnpy: numerical modelling of AGN spectra in python

Built on numpy and astropy, agnpy computes the spectral energy distribution (SED) produced by the synchrotron and inverse Compton radiation of relativistic electrons accelerated in the jets of Active Galactic Nuclei. The radiation field of several AGN components (e.g. Accretion Disk, Broad Line Region, Dust Torus) can be selected as target for the inverse Compton and the gamma-gamma pair-production opacity of the latter can be estimated. agnpy hopes to provide an important missing piece in the growing community of python-based astronomical software.

10:10 The joint-crab project: Towards open and reproducible multi-instrument analysis in gamma-ray astronomy

The joint-crab project represents the first multi-instrument, fully-reproducible analysis in gamma-ray astronomy.
A common data format proposed for high-level gamma-ray instruments data is implemented for a small set of Fermi-LAT, MAGIC, VERITAS, FACT, and H.E.S.S observations.
The data were analysed with the open-source software gammapy to produce a joint maximum likelihood fit of the Crab nebula spectrum.
All the results presented in this work are obtained using open-access on-line assets that allow for a long-term reproducibility of the results (Docker, zenodo).

10:15 gLike: likelihood maximization and profiling for astrophysical (and beyond) applications

Based on ROOT, gLike is a framework for the numerical maximization of likelihood functions.
The likelihood has one free parameter (named g) and as many nuisance parameters as wanted, which will be profiled in the maximization process. Multi-instrument likelihood can be created and jointly profiled by compounding together several likelihood terms. gLike has been and is being used for Dark Matter searches in gamma-ray astronomy and will ultimately enter the ESCAPE software collection.

10:20 AstroAnt: astronomical analyses of ANTARES neutrino telecsope data in python

In astronomy it is a common task for a telescope/detector team to provide a software pipeline for

• reducing data to a certain region on the sky,
• applying the most recent calibration knowledge,
• and estimating signal probabilities and signal background.

Using this pipeline enables the astrophysicist to quickly start analyzing and interpreting the data in a scientific context. In particular she or he does not need to have an in-depth knowledge of the telescope and signal detection process.

Neutrino astroparticle physics and astronomy are new and fast emerging fields. Currently, the work around prototype and neutrino telescopes being built concentrates on understanding, improving, and developing technologies. Thus, only limited software pipelines for astrophysical purposes as described above exist.

I will present highlights of the software pipeline AstroAnt developed for the ANTARES neutrino telescope. This pipeline can serve as a prototype for the next-generation KM3NeT neutrino telescope currently being built, in order to kick off astronomical analyses in the next years.
