Left: channel maps showing the CO(1-0) line emission of the “gas blob” (RA 9:00:25.26, Dec +39:03:58.9) located ∼6 kpc north of the main galaxy. The NOEMA beam is shown in the top-left corner of the first panel. The contours show the 2.5σ (dashed line) and 3, 4, 5 and 6σ (solid lines) levels of emission. Right: CO(1-0) spectrum extracted from a circular region with a radius of 1.5″ centered around the “gas blob.”
