University Of Minnesota Radio Astronomy

Bio: Nitza earned her B.S. in Physics and Electronics on the College of Puerto Rico at Humacao. Now she is a part of the employees at Columbia College working as a research assistant. She intends to apply to graduate faculty to obtain a PhD in Astrophysics. Her research interests embrace radio observations of galaxies, galactic construction and star formation. Over the years plenty of different fascinating radio astronomy actions were explored, and most are featured on this website. I’m responsible of failing to maintain this website up to date with the assorted initiatives , technical details and observational results over the last few years.


James Clerk Maxwell (6/13/1831 – eleven/5/1879) was a Scottish mathematician & theoretical physicist. Within the 1860s, his equations showed that electromagnetic radiation from stellar sources might exist with any wavelength, not simply optical. It wasn’t until 1931 that Karl Jansky (10/22/1905 – 02/14/1950), an American physicist and radio engineer with Bell Telephone Laboratories, confirmed the idea. While investigating static that interfered with quick wave transatlantic voice transmissions, Jansky used a large directional antenna to track the interference. He noticed that his analog pen/paper recording system kept recording a repeating sign of unknown origin.



The Astronomy Division could be very energetic in radio astronomy analysis. This web page provides an outline of the folks concerned and the tasks we work on. Many of the projects take a multi-wavelength method, with complemenatry in the infrared, optical, and x-ray regime. The title “Radio Astronomy Research” may thus not be quite correct, but it surely does provide us with a approach to summarize what we do. Latest Research Highlights: Big Void in the Universe The Square Law Detector is a interface from the receiver to therecording device. A straightforward to construct detector is shown beneath. Part placement is notcritical. All resistors are 1/4 watt.


Decision, which can be expressed as beam width, is a function of the wavelength of the signal and the diameter of the reflector. At optical frequencies (blue-inexperienced light 600,000 GHz or a wavelength of0005 mm) a 1 meter diameter “excellent” mirror will have a beam width of about00003 levels. The identical mirror operating at radio frequencies (30 GHz for example with a wavelength of 1 cm) could have a beam width of about 6 degrees. As may be seen, the beam width for the radio telescope is about 200,000 times wider, thus yielding lower resolution observations.


Gentle, clearly, is the physical phenomenon that empowers our capability to use our visual affirmation system, e.g. our eyes to understand something, on this case the celebs. So once we lookup on the heavens, we will see the light emitting from a star or reflecting from a planet or moon. In lots of circumstances, if we see a far-off star, we are actually seeing it a whole bunch or 1000′s of years in the past as a result of that’s how long it takes for that gentle to cross the universe and be seen in our sky. That alone is a fairly mind blowing thought.
