ALMA finds dew drops in the dusty spider's web

• We present 0 ''.5 resolution ALMA detections of the observed 246 GHz continuum, [CI] P-3(2) -> P-3(1) fine structure line ([CI] 2-1), CO(7-6), and H2O lines in the z = 2:161 radio galaxy MRC1138-262, the so-called Spiderweb galaxy. We detect strong [CI] 2-1 emission both at the position of the radio core, and in a second component similar to 4 kpc away from it. The 1100 km s(-1) broad [CI]2-1 line in this latter component, combined with its H-2 mass of 1 : 6 x 10(10) M-circle dot, implies that this emission must come from a compact region
