GW Detector Characterization Workshop 2025

Dec 15, 2025, 9:15 AM → Dec 19, 2025, 5:30 PM Asia/Kolkata

IUCAA, Pune, India

Anupreeta More (IUCAA, Pune), Shivaraj Kandhasamy (IUCAA, Pune)

This workshop aims to introduce various aspects of GW detector characterization and tools, and to encourage the Indian GW community to undertake research on detector characterization, which is crucial during the commissioning phase of LIGO India. This event is supported by IUCAA and the U.S. National Science Foundation grant OISE-2201990 (HSF-India).
