Realistic Detection and Early Warning of Binary Neutron Stars with Decihertz Gravitational-wave Observatories

Posted by klaurent Peking

Kavli Affiliate: Lijing Shao | First 5 Authors: Chang Liu, Yacheng Kang, Lijing Shao, , | Summary: We investigated the detection and localization of binary neutron star (BNS) populations with decihertz gravitational-wave observatories in a realistic detecting strategy, including real-time observations and early warnings. Assuming 4 years’ operation of B-DECIGO, we found that the detected […]

Ejection-accretion connection in NLS1 AGN 1H 1934-063

Posted by klaurent MIT

Kavli Affiliate: Erin Kara | First 5 Authors: Yerong Xu, Ciro Pinto, Erin Kara, Megan Masterson, Javier A. García | Summary: Accretion and ejection of matter in active galactic nuclei (AGN) are tightly connected phenomena and represent fundamental mechanisms regulating the growth of the central supermassive black hole and the evolution of the host galaxy. […]

Edge observables of the Maxwell-Chern-Simons theory

Posted by klaurent MIT

Kavli Affiliate: J. S. Villasenor | First 5 Authors: J. Fernando Barbero G., Bogar Díaz, Juan Margalef-Bentabol, Eduardo J. S. Villaseñor, | Summary: We analyze the Lagrangian and Hamiltonian formulations of the Maxwell-Chern-Simons theory defined on a manifold with boundary for two different sets of boundary equations derived from a variational principle. We pay special […]

A High-Time Resolution Search for Compact Objects using Fast Radio Burst Gravitational Lens Interferometry with CHIME/FRB

Posted by klaurent MIT

Kavli Affiliate: Kiyoshi W. Masui | First 5 Authors: Zarif Kader, Calvin Leung, Matt Dobbs, Kiyoshi W. Masui, Daniele Michilli | Summary: The gravitational field of compact objects, such as primordial black holes, can create multiple images of background sources. For transients such as fast radio bursts (FRBs), these multiple images can be resolved in […]

Measuring quasi-normal mode amplitudes with misaligned binary black hole ringdowns

Posted by klaurent MIT

Kavli Affiliate: Scott A. Hughes | First 5 Authors: Halston Lim, Gaurav Khanna, Scott A. Hughes, , | Summary: In recent work, we examined how different modes in the ringdown phase of a binary coalescence are excited as a function of the final plunge geometry. At least in the large mass ratio limit, we found […]
