HCN emission from translucent gas and UV-illuminated cloud edges revealed by wide-field IRAM 30 m maps of the Orion B GMC - Revisiting its role as a tracer of the dense gas reservoir for star formation

Fig. 1

Composite image of the ~5 deg² area mapped in Orion B. Red color represents the PACS 70 μm emission tracing FUV-illuminated extended warm dust. Green color represents the cloud depth in magnitudes of visual extinction, A_V ∝ N(H₂). Blue color represents the HCN J = 1−0 line intensity. We note that outside the main filaments most of the HCN J =1−0 emission is at A_V < 4 mag.
