It can be used when referring to the initial identification or discovery of something, often in scientific or technical contexts.
Example: "The researchers announced a first detection of gravitational waves, marking a significant milestone in astrophysics."
Alternatives: "an initial detection of" or "the inaugural detection of".
This record result, very close to the predicted limit, demonstrates the feasibility of reaching such sensitivities, and opens the way to designing a dedicated apparatus for a first detection of vacuum magnetic birefringence.
Along the way, I will discuss novel techniques that have been developed for moving beyond technical hurdles (such as foreground contamination) to a first detection of the cosmological 21cm signal.
