(Phys.org)—A team of undergraduates from the Indian Institute of Science Education and Research (IISER) at the College of Engineering in Trivandrum, India, has designed and constructed a portable college-level radio telescope for amateur radio astronomers. The students have developed a radio telescope and also data analysis tools that are affordable for schools and colleges, combining low cost and ubiquitous accessibility of resources needed to build these instruments. The team described the project in details in a paper published online on Jan. 12 on the arXiv pre-print server.
