"This means that, using the VLBA
, we now can accurately map the whole extent of our galaxy.
is operated by the National Radio Astronomy Observatory (NRAO).
Using the radio-wave portion of the spectrum, the VLBA
can receive emissions from such objects.
, part of the Long Baseline Observatory, is a continent-wide radio telescope system using ten, 240-ton dish antennas distributed from Hawaii to St.
When Neff's team took a second look with the VLBA
last February, it found a fifth supernova.
"The data we get from the VLBA
is very high quality.
Boston University astronomers Alan Marscher and Svetlana Jorstad routinely monitor 4C +71.07 along with dozens of other blazars using several facilities, including the VLBA
Diamond, both of the National Radio Astronomy Observatory in Socorro, N.M., weren't sure what to expect when they began studying the star with the Very Long Baseline Array (VLBA
), a network of telescopes stretching from Hawaii to the Virgin Islands.
"These things should be out there, but because they are so dim they are very hard to find." Kaplan and his colleagues found this stellar gem using the National Radio Astronomy Observatory's (NRAO) Green Bank Telescope (GBT) and Very Long Baseline Array (VLBA
), as well as other observatories.
The data comes from observations from NASA's Rossi X-ray Timing Explorer (RXTE) satellite and the National Science Foundation's (NSF) Very Long Baseline Array (VLBA
) radio telescope.
All three were built: the Chandra X-ray Observatory, the Far Ultraviolet Spectroscopic Explorer (FUSE), and the Very Long Baseline Array (VLBA
The unusually high resolution of the network of 10 radio telescopes, collectively known as the Very Long Baseline Array (VLBA
), enabled researchers to record structures deep within the spiral galaxy NGC 4258, which lies some 21 million light-years from Earth.
