Eccentricity as a Magnifying Glass: Precision Population Inference Enabled by Eccentric Neutron Star-Black Hole Mergers
Alberto Salvarese, Hsin-Yu Chen, Aaron Zimmerman +1
The formation history of compact binary systems remains one of the key open questions in astrophysics. Theoretical studies generally favor isolated binary evolution for neutron sta…
Binary Neutron Star Merger Evolution and r-Process Enrichment in the Milky Way Disk
Joon Young Lee, Hsin-Yu Chen, Muhammed Saleem
The origin of half of the rapid neutron-capture nucleosynthesis (r-process) elements in the Universe remains an open question. Binary neutron star (BNS) mergers have been shown to…
Golden and Silver Dark Sirens for precise H0 measurement with HETDEX
Yixuan Dang, Ish Gupta, Robin Ciardullo +12
Gravitational waves (GWs) from compact binary coalescences are standard sirens that provide a direct measure of the source's luminosity distance, enabling an independent measuremen…
Identifying the host of compact binary mergers
Alberto Salvarese, Hsin-Yu Chen, Daniel E. Holz
Finding the host galaxies of stellar-mass compact binary mergers will open a new window for studying their formation histories and measuring key cosmological parameters, such as th…
Listening Across the Cosmic Time: Standard Sirens from Ground- and Space-Based Missions in the Next Decade
Alberto Salvarese, Hsin-Yu Chen, Alberto Mangiagli +1
Precise measurement of the Hubble parameter will enable stringent tests of the standard model for cosmology. Standard sirens, using the luminosity distances measured by gravitation…
Mitigating the binary viewing angle bias for standard sirens
Alberto Salvarese, Hsin-Yu Chen
The inconsistency between experiments in the measurements of the local Universe expansion rate, the Hubble constant, suggests unknown systematics in the existing experiments or new…
