B-mode targets
The CMB-S4 Science Book [1], Simons Observatory report [2], Astro2020 Science White Paper on gravitational waves [3], and PICO report [4] contain an extensive discussion of many ongoing and planned efforts in the search for gravitational waves produced by inflation. Here we give a short executive su...
