Prediction of space distribution of young neutron stars as sources of gravitational waves — •Markus Hohle — AIU, Jena, Germany

In my talk I would like to introduce methods and ideas to find nearby young neutron stars and how to estimate a prediction for a distribution of these objects. This leads to constrains of certain areas in the sky where a neutron star excess could be expected. Dense objects like neutron stars and black holes, or the binary systems of them and supernova events are sources of gravitational waves.

The question of how many neutron stars could be detected depends strong on their physical behaviour, such as kick velocity and assumed cooling scenario.

The main interests are on young isolated neutron stars, which enable us in principle to constrain the equation of state.

Furthermore I would talk about a new estimation of the supernova rate for the solar vicinity compared with previous ones and other population synthesises and I will discuss how reliable are these predictions.
