A semicoherent resampling method for long-transient gravitational wave searches with applications to subsolar-mass primordial black-hole binaries
Neil Lu, Cristiano Palomba, Ornella J. Piccinni +1
Resampling removes the modeled phase evolution of a frequency-evolving signal, transforming it into a monochromatic one. We introduce a novel implementation for long-transient grav…
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…
Alternative neural-network follow-up for all-sky FrequencyHough in continuous gravitational-wave searches
Martina Di Cesare, Pia Astone, Rosario De Rosa +3
Continuous gravitational waves are long-lived signals emitted by spinning neutron stars (NSs) or boson clouds around black holes. While the Milky Way is expected to host $\mathrm{O…
A semi-coherent generalization of the 5-vector method to search for continuous gravitational waves
S. D'Antonio, C. Palomba, P. Astone +8
The emission of continuous gravitational waves (CWs), with duration much longer than the typical data taking runs, is expected from several sources, notably spinning neutron stars,…
