The researchers searched for pulsars in a sample of 97 globular clusters. The strongest candidate turned out to be the source in GLIMPSE-C01, located about 10,760 light-years from Earth. The newly discovered pulsar, designated GLIMPSE-C01A, has a rotation period of 19.78 milliseconds and a dispersion measure, which shows the number of electrons in the line of sight between Earth and the pulsar, of 491.1 parsecs per cubic centimetre.
The characteristic age of this pulsar is estimated to be 100 million years. A strong magnetic field at the one billion gauss level is also suspected, as the pulsar has a higher luminosity in hard X-rays (2-10 kiloelectronvolts) than most such objects in globular clusters.
