The GIGA group.
Gravitational-wave Inference from Gamma-rays and the Array. We are the only research programme in the
Netherlands dedicated to nanohertz gravitational‑wave astrophysics, based at ASTRON and led by
Dr. Aditya Parthasarathy. The group is supported by a European Research Council Starting Grant and an
NWO-I Veni fellowship, together worth over €2M.
Pillar I
Science
Noise modelling, gravitational‑wave background characterisation, and multi-messenger follow-up with international PTA collaborations.
Pillar II
Instruments
MeerKAT backends, a phased-array feed with Breakthrough Listen, the Gamma-ray PTA on NASA's Fermi, and the Westerbork upgrade.
Pillar III
AI pipelines
meerpipe, TempoNest, and next-generation Bayesian inference engines that make precision pulsar timing tractable at scale.
A dedicated group website is coming soon.
In the meantime, you can find details of current members, open positions, and ongoing projects by
contacting Aditya directly.
