We are searching for neutron stars and black holes in two galaxies that are so nearby that you can see them with the naked eye. These black holes and neutron stars are pulling off material from a nearby companion star in a process called accretion. Studying the way these objects spin and accrete matter helps us learn more about how galaxies, stars and even planets form and grow.
Accreting black holes and neutron stars emit all kinds of light, from high energy X-rays right down to radio waves. So in order for us to detect and study them, we will be using data from ground and space-based telescopes to look for these objects. One of the instruments we will use is called the MeerKAT radio telescope, which is being built in South Africa. MeerKAT will be the largest and best radio telescope in the southern hemisphere. The construction of this telescope has been a huge driver of innovation and technology in South Africa. The MeerKAT project is also creating new collaborative ties with the astronomy community around the world, and the UK in particular. Therefore, this a very exciting time to be involved in astronomy research in South Africa and the UK.
