Spatially filtered ALMA observations of the OMC-2 region at 3 mm (right) and VISTA K_s observationsof the same area (left) (Meingast et al. 2016). Point sources detected in the ALMA data are shown: disks and protostars from the Megeath et al. (2012) catalog (red circles and blue squares, respectively); sources without detected counterparts in this catalog (black triangles). White stars indicate the locations of the Trapezium stars θ¹ Ori A – D and HD 37061; the dashed black line indicates the photoionization region around the Trapezium out to 0.5 pc, while M 42 is marked by the dotted circle. The Orion KL outflow is shown by the yellow star.
