Benchmarking Irish Private-Sector Credit

Strong credit growth since the mid-1990s has resulted in a near doubling of Ireland’s private-sector credit to Gross Domestic Product ratio.

The Irish Pound: From Origins to EMU

This article provides a brief overview of the Irish pound’s origins, before looking in more detail at the questioning of the sterling link and events leading up to Ireland joining the EMS.

Decoding mode-mixing in black-hole merger ringdown

Optimal extraction of information from gravitational-wave observations of binary black-hole coalescences requires detailed knowledge of the waveforms. Current approaches for representing waveform information are based on spin-weighted spherical harmonic decomposition. Higher-order harmonic modes carrying a few percent of the total power output near merger can supply information critical to determining intrinsic and extrinsic parameters of the binary. One obstacle to constructing a full multi-mode template of merger waveforms is the apparently complicated behavior of some of these modes; instead of settling down to a simple quasinormal frequency with decaying amplitude, some $|m| \neq \ell$ modes show periodic bumps characteristic of mode-mixing. We analyze the strongest of these modes -- the anomalous $(3,2)$ harmonic mode -- measured in a set of binary black-hole merger waveform simulations, and show that to leading order, they are due to a mismatch between the spherical harmonic basis used for extraction in 3D numerical relativity simulations, and the spheroidal harmonics adapted to the perturbation theory of Kerr black holes. Other causes of mode-mixing arising from gauge ambiguities and physical properties of the quasinormal ringdown modes are also considered and found to be small for the waveforms studied here.Comment: 15 pages, 10 figures, 2 tables; new version has improved Figs. 1-3, consistent labelling of simulations between Tables I & II, additional/corrected references, and extra hyphen
