Despite predicted FRB rates as high as 10,000 per day, the VLA and VLBA
teams don't expect to find many bursts--one or two at most.
is operated by the National Radio Astronomy Observatory (NRAO).
As a result, The VLBA resolves detail about a million times smaller than Fermi's Large Area Telescope (LAT) and 1,000 times smaller than NASA's Hubble Space Telescope.
In autumn 2011, the VLBA images revealed a bright knot that appeared to move outward at a speed 20 times faster than light.
In early June 2009, H1743-322 underwent this transition as astronomers watched with RXTE, the VLBA
, the Very Large Array near Socorro, N.
In addition to measuring the distance, the VLBA
observations, made during 2009 and 2010, also measured Cygnus X-1's movement through our Galaxy.
is an instrument of the National Radio Astronomy Observatory.
New measurements with the VLBA
have placed a galaxy called NGC 6264 at a distance of 450 million light-years from Earth, with an uncertainty of no more than nine percent.
showed us with great precision where the radio emission came from, so we know the gamma rays came from closer in toward the black hole," he added.
Bower and his colleagues were studying the motion of M82 with the VLBA
, which links the VLA and nine other radio telescopes into a very high resolution instrument, when they noticed a very bright radio source - five times brighter than anything else in the galaxy - in the VLA data.
can resolve details about a million times smaller than Fermi can and 50 times smaller than any optical telescope.
These areas, called cosmic masers, serve as bright landmarks for the sharp radio vision of the VLBA
