Slingshot on compact binaries in the nuclear region of galaxies as the origin of large offset gamma-ray bursts
Juan C. Rodríguez-Ramírez, Viviane Alfradique, Clécio R. Bom +1
A growing number of gamma-ray bursts (GRBs) have been observed at large projected offsets from the centres of their putative host galaxies, sometimes extending to several tens of k…
Improved constraint on the Hubble constant from dark sirens with LIGO/Virgo/KAGRA O4a
V. Alfradique, C. R. Bom, G. Teixeira +1
A new measurement of the Hubble constant is presented using the statistical dark siren method applied to a sample of seven well-localized gravitational-wave (GW) events from…
Systematic bias in dark siren statistical methods and its impact on Hubble constant measurement
V. Alfradique, C. R. Bom, T. Castro
The advent of multimessenger cosmology, marked by the detection of GW170817, demonstrated that standard sirens are a valuable cosmological probe. In the absence of an electromagnet…
A deconstruction of methods to derive one-point lensing statistics
Viviane Alfradique, Tiago Castro, Valerio Marra +3
Gravitational lensing is a crucial tool for exploring cosmic phenomena, providing insights into galaxy clustering, dark matter, and dark energy. Given the substantial computational…
A dark standard siren measurement of the Hubble constant following LIGO/Virgo/KAGRA O4a and previous runs
C. R. Bom, V. Alfradique, A. Palmese +4
We present a new constraint on the Hubble constant () from the standard dark siren method using a sample of well-covered gravitational waves (GW) alerts reported during th…
A dark siren measurement of the Hubble constant using gravitational wave events from the first three LIGO/Virgo observing runs and DELVE
V. Alfradique, C. R. Bom, A. Palmese +17
The current and next observation seasons will detect hundreds of gravitational waves (GWs) from compact binary systems coalescence at cosmological distances. When combined with ind…
The lure of sirens: joint distance and velocity measurements with third generation detectors
Viviane Alfradique, Miguel Quartin, Luca Amendola +2
The next generation of detectors will detect gravitational waves from binary neutron stars at cosmological distances, for which around a thousand electromagnetic follow-ups may be…
