Cosmological mirror symmetry and gravitational-wave helicity
Juan Calderón-Bustillo, Adrian del Rio, Samson H. W. Leong +1
Our current understanding of the Universe relies on the hypothesis that, when observed at sufficiently large scales, it looks statistically identical regardless of location or dire…
Identifying Proca-star mergers via consistent ultralight-boson mass estimates across gravitational-wave events
Ana Lorenzo-Medina, Juan Calderón Bustillo, Samson H. W. Leong
While black-hole and neutron-star mergers are the most plausible sources of current gravitational-wave observations, mergers of exotic compact objects may mimic these signals. Proc…
Gravitational-wave signatures of mirror (a)symmetry in binary black hole mergers: measurability and correlation to gravitational-wave recoil
Samson H. W. Leong, Alejandro Florido Tomé, Juan Calderón Bustillo +2
Precessing binary black-hole mergers can produce a net flux of circularly-polarized gravitational waves. This imbalance between left- and right-handed circularly polarized waves, q…
Testing mirror symmetry in the Universe with LIGO-Virgo black-hole mergers
Juan Calderón Bustillo, Adrian del Rio, Nicolas Sanchis-Gual +2
Certain precessing black-hole mergers produce gravitational waves with net circular polarization, understood as an imbalance between right- and left-handed amplitudes. According to…
Impact of Bayesian Priors on the Inferred Masses of Quasi-Circular Intermediate-Mass Black Hole Binaries
Koustav Chandra, Archana Pai, Samson H. W. Leong +1
Observation of gravitational waves from inspiralling binary black holes has offered a unique opportunity to study the physical parameters of the component black holes. To infer the…
Impact of ringdown higher-order modes on black-hole mergers in dense environments: the scalar field case, detectability and parameter biases
Samson H. W. Leong, Juan Calderón Bustillo, Miguel Gracia-Linares +1
Dense environments hosting compact binary mergers can leave an imprint on the gravitational-wave emission which, in turn, can be used to identify the characteristics of the environ…
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,…
A complete measurement of a black-hole recoil through higher-order gravitational-wave modes
Juan Calderón Bustillo, Samson H. W. Leong, Koustav Chandra
General relativity predicts that gravitational waves (GWs) carry linear momentum. Consequently, the remnant black hole of a black-hole merger can inherit a recoil velocity or ``kic…
Impact of the wave-like nature of Proca stars on their gravitational-wave emission
Nicolas Sanchis-Gual, Juan Calderón Bustillo, Carlos Herdeiro +4
We present a systematic study of the dynamics and gravitational-wave emission of head-on collisions of spinning vector boson stars, known as Proca stars. To this aim we build a cat…
Searching for vector boson-star mergers within LIGO-Virgo intermediate-mass black-hole merger candidates
Juan Calderon Bustillo, Nicolas Sanchis-Gual, Samson H. W. Leong +7
We present the first systematic search for exotic compact mergers in Advanced LIGO and Virgo events. We compare the short gravitational-wave signals GW190521, GW190426190642, G…
Gravitational-wave parameter inference with the Newman-Penrose scalar
Juan Calderon Bustillo, Isaac C. F. Wong, Nicolas Sanchis-Gual +7
Detection and parameter inference of gravitational-wave signals \ncor{from compact mergers} rely on the comparison of the incoming detector strain data to waveform templates…
GW190521 as a black-hole merger coincident with the ZTF19abanrhr flare
Juan Calderón Bustillo, Samson H. W. Leong, Koustav Chandra +2
We present an analysis that reconciles the gravitational-wave signal GW190521 observed by the Advanced LIGO and Advanced Virgo detectors with the electromagnetic flare ZTF19abanrhr…
GW190521 as a merger of Proca stars: a potential new vector boson of eV
Juan Calderón Bustillo, Nicolas Sanchis-Gual, Alejandro Torres-Forné +6
Advanced LIGO-Virgo reported a short gravitational-wave signal (GW190521) interpreted as a quasi-circular merger of black holes, one populating the pair-instability supernova gap,…
Mapping the Universe Expansion: Enabling percent-level measurements of the Hubble Constant with a single binary neutron-star merger detection
Juan Calderón Bustillo, Samson H. W. Leong, Tim Dietrich +1
The joint observation of the gravitational-wave and electromagnetic signal from the binary neutron-star merger GW170817 allowed for a new independent measurement of the Hubble cons…
