Two recent short-author papers involving U\u00b2GRC researchers address complementary challenges in gravitational-wave astronomy: searching for unusual long-duration signals and separating astrophysical information from transient detector noise.<\/p>\n
Long-duration GW Searches for Sub-solar NSs and Superkilonovae using CoCoA<\/em><\/a>, by Abby Tejera, Divyajyoti, Alessandra Corsi, Yossef Zenati, Robert Coyne, and Logan Cote, studies possible gravitational-wave signatures from mergers involving sub-solar-mass neutron stars. Such signals could last hundreds to thousands of seconds and may not be well captured by standard waveform templates. The authors explore how the Cross-Correlation Algorithm (CoCoA) could support targeted follow-up searches, including searches prompted by candidate gravitational-wave events or electromagnetic observations of supernovae.

Tests with simulated and real data show how conclusions about black-hole spin can depend on both the waveform model and the treatment of detector noise. The work provides a flexible framework for more reliable inference when signals overlap with non-Gaussian noise transients. INSPIRE record<\/a>.<\/p>\n
