Jets, Disks and Winds from Spinning Black Holes: Nature or Nurture?

Kavli Affiliate: Roger Blandford | First 5 Authors: Roger Blandford, Noemie Globus, , , | Summary: A brief summary is given of an alternative interpretation of the Event Horizon Telescope observations of the massive black hole in the nucleus of the nearby galaxy M87. It is proposed that the flow is primarily powered by the […]

An Isotropy Measurement with Gravitational Wave Observations

Kavli Affiliate: Daniel E. Holz | First 5 Authors: Reed Essick, Will M. Farr, Maya Fishbach, Daniel E. Holz, Erik Katsavounidis | Summary: We constrain the distribution of merging compact binaries across the celestial sphere using the GWTC-3 catalog from the LIGO-Virgo-KAGRA Collaborations’ (LVK) third observing run. With 63 confident detections from O3, we constrain […]

Direct detection of dark photon dark matter using radio telescopes

Kavli Affiliate: Jia Liu | First 5 Authors: Haipeng An, Shuailiang Ge, Wen-Qing Guo, Xiaoyuan Huang, Jia Liu | Summary: Dark photon can be the ultralight dark matter candidate, which can interact with the Standard Model particles via the kinetic mixing. We propose to look for ultralight dark photon dark matter (DPDM) with local absorption […]

The Gravitational Afterglow of Boson Stars

Kavli Affiliate: Ulrich Sperhake | First 5 Authors: Robin Croft, Thomas Helfer, Bo-Xuan Ge, Miren Radia, Tamara Evstafyeva | Summary: In this work we study the long-lived post-merger gravitational wave signature of a boson-star binary coalescence. We use full numerical relativity to simulate the post-merger and track the gravitational afterglow over an extended period of […]
