DOI: 10.1016/j.newast.2017.04.013
Abstract: Abstract New strong non-spiralling-in gravitational wave (GW) source for LIGO/VIRGO detectors are proposed. Double O Ne–Mg white dwarf mergers can produce strong gravitational waves with frequencies in the several hundreds Hz range. Such events can… read more here.

DOI: 10.1051/0004-6361/201936528
Abstract: All ten LIGO/Virgo binary black hole (BH-BH) coalescences reported following the O1/O2 runs have near-zero effective spins. There are only three potential explanations for this. If the BH spin magnitudes are large, then: (i) either… read more here.

DOI: 10.1088/1475-7516/2021/03/068
Abstract: We analyse the LIGO-Virgo data, including the recently released GWTC-2dataset, to test a hypothesis that the data contains more than one population of black holes. We perform a maximum likelihood analysis including a population of… read more here.

DOI: 10.1088/1475-7516/2023/04/024
Abstract: String cosmology models predict a relic background of gravitational-wave (GW) radiation in the early universe. The GW energy spectrum of radiated power increases rapidly with the frequency, and therefore it becomes a potential and meaningful… read more here.
