The first neutron star-neutron star merger was detected in by LIGO/Virgo in a galaxy in which the majority of star formation was taking place a long time ago (11 Gyr). LIGO/Virgo estimated that local cosmic NS-NS merger rate is 110-3840 Gpc^-3 yr^-1. Only some extreme evolutionary models can generate NS-NS merger rates in old host galaxies consistent with the LIGO/Virgo estimate. However, we show that these models generate rates exceeding empirical Galactic NS-NS merger rates based on the large… Expand

Merging Rates of Compact Binaries in Galaxies: Perspectives for Gravitational Wave Detections.
We investigate the merging rates of compact binaries in galaxies, and the related detection rate of gravitational wave (GW) events with AdvLIGO/Virgo and with the Einstein Telescope. To this purpose,Expand
R-process enrichment in ultrafaint dwarf galaxies
• Physics
• 2020
We study the enrichment and mixing of r-process elements in ultrafaint dwarf galaxies (UFDs). We assume that r-process elements are produced by neutron-star mergers (NSMs), and examine multipleExpand
Neutron Star Mergers Might Not Be the Only Source of r -process Elements in the Milky Way
Probing the origin of r-process elements in the universe represents a multidisciplinary challenge. We review the observational evidence that probes the properties of r-process sites, and address themExpand

We determine the ability of Cosmic Explorer, a proposed third-generation gravitational-wave observatory, to detect eccentric binary neutron stars and to measure their eccentricity. We find that for aExpand
Constraining delay time distribution of binary neutron star mergers from host galaxy properties
• Physics
• 2020
Gravitational wave (GW) observatories are discovering binary neutron star mergers (BNSMs), and in at least one event we were able to track it down in multiple wavelengths of light, which allowed usExpand
Simulating kilonovae in the ΛCDM universe
Kilonovae are optical flashes produced in the aftermath of neutron star-neutron star mergers (NNMs) or neutron star-black hole mergers (NBMs). In this work, we use the Millennium Simulation, combinedExpand
