GRB 191221B: ALMA detection
Abstract
"We observed GRB 191221B (Laha et al. GCN 26534) with the Atacama Large Millimeter/Submillimeter Array (ALMA) beginning on 2019 December 22 at 07:43:55 UT (11.1 hr after the burst) at 97.5 GHz under good weather conditions. Preliminary analysis reveals a bright (S/N > 300) mm source at position: 10:19:19.225 (+/- 0.005), -38:09:27.45 (+/- 0.01) consistent with the X-ray position (Beardmore et al. GCN 26540) and optical position (Lipunov et al., GCN 26537). Follow-up observations are planned. We thank the JAO staff, AoD, P2G, and the entire ALMA team for their help with these observations."
