Intern in the Science Operations Department - Discovering Astronomical Anomalies with AnomalyMatch

Location

ESAC, Villanueva de la Cañada, Spain

Our team and mission

Under the direct authority of D/SCI, the Head of the Science Operations Department is responsible for the development of the science operations infrastructure under the Directorate responsibility, the operation of the Directorate’s missions once successfully commissioned, and the curation of all scientific data in the missions’ legacy phase. These responsibilities are discharged in full coordination with the Directorate’s Departments and Offices and as appropriate, with the Directorate of Operations (D/OPS).

In implementing their duties, SCI-S is supported by the

• Mission Management and Science Operations Division (SCI-SO);
• Science Operations Development Division (SCI-SD);
• Data Science and Archives Division (SCI-SA).

Candidates interested are encouraged to visit the ESA website: http://www.esa.int

Topic of the internship: Beyond Images: Discovering Astronomical Anomalies in Light Curves and Spectra with AnomalyMatch.

Astronomical archives contain vast collections of spectra and light curves that may hide rare objects, unusual variability, and unexpected physical phenomena. This project will extend AnomalyMatch, a semi-supervised and active-learning framework for finding scientifically interesting anomalies from only a few labelled examples, to support such one-dimensional data.

AnomalyMatch recently received global press attention after discovering hundreds of previously unknown anomalies in the Hubble archive and has demonstrated the capacity to trawl hundreds of millions of astronomical cutouts. It is also integrated into ESA Datalabs, allowing researchers to apply the tool directly to large astronomical datasets and scalable computing resources.

So far, AnomalyMatch has been limited to image data. You will adapt its machine-learning methodology and software for spectra and/or light curves and validate the resulting approach on real astronomical datasets. The project may also explore combining measurements from different telescopes or instruments, opening new possibilities for discovering objects that appear ordinary in one dataset but unusual when multiple observations are considered together.
