Multi log-normal density structure in Cygnus-X molecular clouds: A fitting for N-PDF without power-law

Takeru Murase, Toshihiro Handa, Ren Matsusaka +6

We studied the H${}_2$ column density probability distribution function (N-PDF) based on molecular emission lines using the Nobeyama 45-m Cygnus X CO survey data. Using the DENDROGRA…
