MeerKAT telescope captures celestial 'Mini Mouse'
Originally Published 2 years ago — by Phys.org
The MeerKAT radio telescope has discovered a new radio nebula, dubbed "the Mini Mouse," during observations of the black hole binary GRS 1915+105. The Mini Mouse is a young radio pulsar escaping its birth site and creating a radio nebula with a cometary-like morphology. The pulsar, PSR J1914+1054g, has a spin period of approximately 138.9 milliseconds and dispersion measure of about 418.9 pc/cm3. The distance to the pulsar was estimated to be 26,700 light years. This is the fourth case of a bow shock associated with an escaping pulsar, for which both the pulsar signal and the supernova remnant associated with its birth have been observed.
