The star formation efficiency per free-fall time ( ε rm ff ) quantifies how efficiently giant molecular clouds (GMCs) convert gas into stars and is often observed to be orders of magnitude lower than expected for…
Using a data sample of (2712.4 pm14.4)x 10 6 ψ(3686) events collected with the BESIII detector, we report a high-precision study of the π 0 π 0 mass spectrum from ψ(3686) rightarrowπ 0 π ....
Edge-on protoplanetary disks provide a spatially resolved view of the vertical distribution of icy planetary building blocks, but inferring their relative abundances requires ....
