Description
The LOFAR Two-metre Sky Survey (LoTSS) Data Release 3 (DR3) now surpasses its predecessor, DR2, in both scope and source count—covering nearly 90% of the northern sky and revealing millions of new radio sources. Identifying optical and infrared counterparts to these sources is essential for determining their properties (e.g. redshift, morphology, luminosity) and enabling further scientific analysis.
While DR2 cross-matching relied on a combination of statistical techniques and citizen science, the scale of DR3 demands a more efficient and scalable approach. This talk presents a new cross-matching pipeline developed to complement the original DR2 methodology. I will outline current automated techniques used to reduce reliance on manual inspection and discuss ongoing efforts to integrate LoTSS DR3 with new optical/IR data from the Euclid mission.
