Likelihood for a Network of Gravitational-Wave Detectors with Correlated Noise
Francesco Cireddu, Milan Wils, Isaac C. F. Wong +3
The Einstein Telescope faces a critical data analysis challenge with correlated noise, often overlooked in current parameter estimation analyses. We address this issue by presentin…
Inferring properties of dark galactic halos using strongly lensed gravitational waves
Eungwang Seo, Tjonnie Guan Feng Li, Martin Anthony Hendry
Gravitational waves (GWs) can be deflected, similarly to electromagnetic (EM) waves, by massive objects through the phenomenon of gravitational lensing. The importance of gravitati…
General-relativistic radiation transport scheme in Gmunu II: Implementation of novel microphysical library for neutrino radiation -- Weakhub
Harry Ho-Yin Ng, Patrick Chi-Kit Cheong, Alan Tsz-Lok Lam +1
We introduce \texttt{Weakhub}, a novel neutrino microphysics library that provides opacities and kernels beyond conventional interactions used in the literature. This library inclu…
Characterizing Gravitational Wave Detector Networks: From A to Cosmic Explorer
Ish Gupta, Chaitanya Afle, K. G. Arun +44
Gravitational-wave observations by the Laser Interferometer Gravitational-Wave Observatory (LIGO) and Virgo have provided us a new tool to explore the Universe on all scales from n…
Cosmic Explorer: A Submission to the NSF MPSAC ngGW Subcommittee
Matthew Evans, Alessandra Corsi, Chaitanya Afle +73
Gravitational-wave astronomy has revolutionized humanity's view of the universe, a revolution driven by observations that no other field can make. This white paper describes an obs…
Gravitational wave signatures from the phase-transition-induced collapse of a magnetized neutron star
Anson Ka Long Yip, Patrick Chi-Kit Cheong, Tjonnie Guang Feng Li
Strong magnetic fields make neutron stars potential sources of detectable electromagnetic and gravitational-wave signals. Hence, inferring these magnetic fields is critical to unde…
Oscillations of Highly Magnetized Non-rotating Neutron Stars
Man Yin Leung, Anson Ka Long Yip, Patrick Chi-Kit Cheong +1
Highly magnetized neutron stars are promising candidates to explain some of the most peculiar astronomical phenomena, for instance, fast radio bursts, gamma-ray bursts, and superlu…
Formation of a magnetized hybrid star with a purely toroidal field from phase-transition-induced collapse
Anson Ka Long Yip, Patrick Chi-Kit Cheong, Tjonnie Guang Feng Li
Strongly magnetized neutron stars are popular candidates for producing detectable electromagnetic and gravitational-wave signals. Gravitational collapses of neutron stars triggered…
Science with the Einstein Telescope: a comparison of different designs
Marica Branchesi, Michele Maggiore, David Alonso +73
The Einstein Telescope (ET), the European project for a third-generation gravitational-wave detector, has a reference configuration based on a triangular shape consisting of three…
General-relativistic radiation transport scheme in I: Implementation of two-moment based multi-frequency radiative transfer and code tests
Patrick Chi-Kit Cheong, Harry Ho-Yin Ng, Alan Tsz-Lok Lam +1
We present the implementation of two-moment based general-relativistic multi-group radiation transport module in the eneral-relativistic ltigrid $\texttt{n…
Exploring the hidden Universe: A novel phenomenological approach for recovering arbitrary gravitational-wave millilensing configurations
Anna Liu, Isaac C. F. Wong, Samson H. W. Leong +3
Since the first detection of gravitational waves in 2015, gravitational-wave astronomy has emerged as a rapidly advancing field that holds great potential for studying the cosmos,…
