Engineering physics senior Angel Hernandez is spending the summer looking to the stars and learning the fundamentals of radio astronomy.

Earlier this summer, Hernandez completed a boot camp on radio astronomy at the Green Bank Observatory (GBO) in West Virginia. Now he鈥檚 at the National Radio Astronomy Observatory鈥檚 Research Experience for Undergraduates (REU) program where he continues to explore the field.

Boot camp takes Hernandez to new heights

During the week-long boot camp at the Green Bank Observatory, students from around the country met with their peers, dove into the basics of radio astronomy, and conducted observations using the 40-foot telescope with a four-person team. The students even toured the enormous Robert C. Byrd Green Bank Telescope that stands about 485 feet above ground level, which Hernandez said tested his fear of heights.

Radio astronomy uses massive telescopes to detect celestial objects like stars and galaxies through radio frequencies. Since its establishment by Karl Jansky in the 1930s, the technique has led to the discovery of pulsars, quasars, and radio galaxies.

Hernandez said the best part of the boot camp was hearing about all the science that radio astronomy has contributed to. 鈥淭he engineering behind a radio telescope is quite sophisticated and the science from observations has given us further insight on what is out there in our universe,鈥� he said.

Because the observatory is in a radio quiet zone to avoid interference, there is no cell phone service or wireless internet. But there鈥檚 plenty to learn and do, and the break from constant connection was welcomed by Hernandez.

鈥淣ot having cell service or wireless internet wasn鈥檛 bad at all,鈥� he said. 鈥淚t was really nice to be disconnected from the outside world, read without distractions, and go on various hikes.鈥� The break also helped him get as much sleep as he could. Hernandez and his team were assigned the 2am to 5am time block to conduct their observations.

The boot camp was a precursor to the National Radio Astronomy Observatory鈥檚 REU program, which Hernandez is attending this summer in Charlottesville, Virginia.

Through the REU, Hernandez hopes to narrow down his research interests. 鈥淚 have never directly worked with observational data before and have always been curious about the methods behind observations,鈥� he said.

Hernandez is a military veteran who returned to pursue his undergraduate education in engineering physics at 精品SM在线影片 after serving in the Marine Corps. His research activities have included fluid dynamics with Professor Michael Calkins, a summer research experience at Los Alamos National Laboratory, and now, radio astronomy.

He is currently working on a computational astrophysics project to model the stellar atmosphere of a binary system of a massive star and black hole.
