AO scientists were first authors for five presentations and served as co-authors for additional presentations. AO senior scientist Shikha Raizada was invited to deliver two presentations while AO scientists Christiano Brum, Selvaraj Dharmalingam and Sukanta Sau contributed one presentation each. + Read More

On December 1st, 2020, the 900-ton instrument platform of the Arecibo radio telescope in Puerto Rico suffered a series of cascading catastrophic cable failures causing it to crash down into the telescope’s 305-meter reflector dish.
