Search for Long-Transient Gravitational Waves from Supernova SN2023ixf using GFH-v2 Pipeline
Sandhya Sajith Menon, Lorenzo Pierini, Pia Astone +24
We present a directed search for long-transient gravitational waves from the possible newborn magnetar remnant of SN2023ixf, a nearby Type II core-collapse supernova in the M101 ga…
GFH-v2 Pipeline for Searches of Long-Transient Gravitational Waves from Newborn Magnetars
Sandhya Sajith Menon, Lorenzo Pierini, Pia Astone +11
This paper presents an enhanced methodology for searching long transient gravitational waves associated with a newborn magnetar, with particular focus on the regime in which the ea…
GW241011 and GW241110: Exploring Binary Formation and Fundamental Physics with Asymmetric, High-Spin Black Hole Coalescence
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1783
We report the observation of gravitational waves from two binary black hole coalescences during the fourth observing run of the LIGO--Virgo--KAGRA detector network, GW241011 and GW…
GW230814: investigation of a loud gravitational-wave signal observed with a single detector
The LIGO Scientific Collaboration, The Virgo Collaboration, The Kagra Collaboration +1783
GW230814, detected by the LIGO Livingston observatory with a signal-to-noise ratio of 42.4, represents the loudest gravitational-wave signal in the GWTC-4.0 catalog. Its source is…
A directed continuous-wave search from Scorpius X-1 with the five-vector resampling technique
Francesco Amicucci, Paola Leaci, Pia Astone +8
Continuous gravitational-wave signals (CWs), which are typically emitted by rapidly rotating neutron stars with non-axisymmetric deformations, represent particularly intriguing tar…
Neural network method to search for long transient gravitational waves
Francesca Attadio, Leonardo Ricca, Marco Serra +11
We present a new method to search for long transient gravitational waves signals, like those expected from fast spinning newborn magnetars, in interferometric detector data. Standa…
