This is another update on the pulsar near Sgr A* that I’ve been writing posts about the last days. This piece of news comes again from the world of X-ray astronomy, after the last updates using radio observations. „Spindown measurement of PSR J1745-2900?“ weiterlesen
Update: Radio Pulsar near Sgr A*
As of May 4, another piece of information about the recently discovered radio pulsar a mere 3“ away from Sgr A* at the Galactic Centre has been published via the ATel #5043. The astronomers at the Max Planck Institute for Radio Astronomy (MPIfR) in Bonn, Germany, had another look at the source using the 100-meter Effelsberg telescope. „Update: Radio Pulsar near Sgr A*“ weiterlesen
A magnetar / SGR / radio pulsar only 3“ from Sgr A*
In case you haven’t been following this, there’s a really interesting story unfolding in a series of ATels about a magnetar/SGR with a radio pulsar counterpart at a very small angular distance (3“) to Sgr A*.
If this were a pulsar in an orbit around the central black hole, this would be one of the holy grails of astronomy, since it could potentially be used to probe the space-time around the black hole with unprecedented precision. I’ve tried to summarize the whole story with its various twists and turns below. „A magnetar / SGR / radio pulsar only 3“ from Sgr A*“ weiterlesen
