Talk:Pulsar timing array

Negative 2015 result

This negative result should be discussed. --mfb (talk) 12:30, 28 November 2015 (UTC)[reply]

What is "quadrupolar correlation"?

I just tagged the article for clarification. Is it sort of like triangulation in a higher dimension? That is, not to determine something's location of course, just to determine that there's oscillation along a certain axis (namely, x, y, or z, plus a control for time) — W.andrea (talk) 05:16, 31 March 2024 (UTC)[reply]

quadrupolar correlation is a correlation in the quadrupole moment tensors of two signals.

The term is not uncommon in the physics literature in general and in pulsar timing publications in particular, e.g. Xu, Heng (2023-06-29). "Searching for the Nano-Hertz Stochastic Gravitational Wave Background with the Chinese Pulsar Timing Array Data Release I". Research in Astronomy and Astrophysics. 23 (7). IOP Publishing: 075024. doi:10.1088/1674-4527/acdfa5. ISSN 1674-4527. Hence I'm going to remove the clarification tag and put in a wikilink to the quadrupole article.
