LIGO A: Detector Design and Science Prospects Beyond A+
L. Sun, K. Kuns, B. J. J. Slagmolen +1153
We present the LIGO A detector concept, an upgrade for the LIGO observatories based on room-temperature interferometers beyond the fifth observing run (O5). Building on th…
All-sky, all-frequency directional search for persistent gravitational-waves from Advanced LIGO's and Advanced Virgo's first three observing runs
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1627
We present the first results from an all-sky all-frequency (ASAF) search for an anisotropic stochastic gravitational-wave background using the data from the first three observing r…
GW230814: investigation of a loud gravitational-wave signal observed with a single detector
The LIGO Scientific Collaboration, The Virgo Collaboration, The Kagra Collaboration +1783
GW230814, detected by the LIGO Livingston observatory with a signal-to-noise ratio of 42.4, represents the loudest gravitational-wave signal in the GWTC-4.0 catalog. Its source is…
Regression on Regression: Mapping Data-Driven Binary Black Hole Merger Rate Fits to Progenitor Histories
Emma Blanchet, Aryanna Schiebelbein-Zwack, Maya Fishbach
The binary black hole (BBH) merger rate is governed by the progenitor formation rate and the distribution of delay-times between formation and merger, but these functions remain po…
Forbidden Formation Histories: The Binary Black Hole Merger Rate Disfavors Long Delay Times
Aryanna Schiebelbein-Zwack, Maya Fishbach
The redshift evolution of the binary black hole (BBH) merger rate can be expressed as the convolution of the progenitor formation rate with the distribution of time delays between…
Evidence of the pair instability gap from black hole masses
Hui Tong, Maya Fishbach, Eric Thrane +13
Stellar theory predicts a forbidden range of black-hole masses between -- due to pair-instability supernovae, but evidence for such a gap in the mass distri…
