About PuMA
First pulsar observations in South America
PuMa, Pulsar Monitoring in Argentina, is a scientific collaboration dedicated to pulsar observation from the south hemisphere. The team, integrated by scientist and technicians from the Argentine Institute of Radioastronomy (IAR) and the Rochester Institute of Technolgy (RIT), is currently working with the two 30 meters single-dish radio antennas in the Institute. Our main goal is to perform long-term observational campaign of pulsars -rapidly-rotating and highly-magnetized neutron stars- to gain a better understanding of their nature. In particular, we observe milisecond pulsars used in pulsar timing arrays and glitching pulsars.
