An Enduring Enigma: Shedding Light on the Text of the Leiden Riddle, 1845–2025

open access: yesSelim
What riddle can be solved, but cannot be read? The Leiden Riddle, which survives on the last folio of Leiden, Leiden University Libraries, VLQ 106, stands out among the Old English riddles for having virtually no discussion about its solution.

Narrowband Searches for Continuous and Long-duration Transient Gravitational Waves from Known Pulsars in the LIGO-Virgo Third Observing Run

open access: yesThe Astrophysical Journal, 2022
Isolated neutron stars that are asymmetric with respect to their spin axis are possible sources of detectable continuous gravitational waves. This paper presents a fully coherent search for such signals from eighteen pulsars in data from LIGO and Virgo’s

GW190814: Gravitational Waves from the Coalescence of a 23 Solar Mass Black Hole with a 2.6 Solar Mass Compact Object

open access: yesThe Astrophysical Journal Letters, 2020
We report the observation of a compact binary coalescence involving a 22.2–24.3 M _⊙ black hole and a compact object with a mass of 2.50–2.67 M _⊙ (all measurements quoted at the 90% credible level).

Search for Multimessenger Sources of Gravitational Waves and High-energy Neutrinos with Advanced LIGO during Its First Observing Run, ANTARES, and IceCube

open access: yesThe Astrophysical Journal, 2019
Astrophysical sources of gravitational waves, such as binary neutron star and black hole mergers or core-collapse supernovae, can drive relativistic outflows, giving rise to non-thermal high-energy emission.
