Continuum images toward L1448N. The left panel shows large-scale 1.1 mm continuum emission of L1448 (Enoch et al. 2006). The beam size is shown in the bottom left corner. The map size of the IRAM 30 m observations is highlighted by the dashed gray rectangle. The right panel shows the NOEMA 1.4 mm continuum of L1448N with contour levels at 5, 25, 60, 120, 200 times σ_cont with σ_cont = 0.78 mJy beam^-1. The triangles and white labels mark the positions of individual protostars (Tobin et al. 2016), and the pink cross marks the recently detected source IRS3-ALMA (Looney et al. 2025). The bipolar outflow directions launched by the three protostellar systems are marked by red and blue arrows, including the blueshifted outflow lobe that is launched by L1448-mm toward the southeast. The synthesized beam of the NOEMA continuum data is shown in the bottom left corner. The scale bars in the two panels are shown in the top left corner.
