52. Using gravitational waves to distinguish between neutron stars and black holes in binaries

Stephanie Brown (Max Planck Institut für Gravitationsphysik)

11/5/20, 3:00 PM

Parallel talk

In August 2017, the first detection of a neutron star merger, GW170817, created an opportunity to explore the equation of state of supranuclear matter using gravitational waves. But it is unknown under what circumstances this kind of gravitational wave data could distinguish between different types of mergers. For example, can the data distinguish a merger of black holes from a merger of...

50. Gravitational waves from hot neutron stars and how to find out more about matter under extreme conditions with them

Gela Hämmerling (Universität Tübingen)

11/5/20, 3:30 PM

Parallel talk

Typical neutron stars have a mass of the order of a solar mass and a radius of about 10 km, making them the most compact objects in our universe. However, the extreme conditions inside a neutron star, i.e., an extremely high density, cannot be reproduced on Earth. Therefore, the equation of state describing extremely compact nuclear matter is still largely unknown. Due to their small size and...

54. Searching for gravitational-wave signals from axions

Sylvia Zhu

11/5/20, 4:00 PM

Parallel talk

Axions are well-motivated theoretical particles that are also dark matter candidates. They can form enormous clouds around black holes, and then annihilate to produce a long-lived, slowly-evolving continuous gravitational-wave signal. This signal is potentially detectable using the current generation of gravitational-wave interferometers, and a non-detection can disfavor the existence of...
