🚨 New header picture 🖼️
It shows the two supernova remnants Cassiopeia A (left, in X-rays) and Vela Jr. (right, at radio wavelengths). Both harbor a “central compact object”, a neutron star left behind together with the debris cloud after the supernova.
Researchers from the permanent independent @maxplanckgesellschaft research group “Continuous Gravitational Waves” at @mpi_grav in Hanover, Germany, have been searching for gravitational waves from these central compact objects using the volunteer distributed computing project @einsteinathome.

The fact that they did not find any gravitational waves indicates that the neutron stars can only be minimally deformed.
