Fig. 1: Histogram of globular cluster pulsars per cluster. Credit: Alessandro Ridolfi. PSR J1823−3022 is possibly associated with the GC NGC 6624; for this reason it is listed below. Pulsar Ter 5 B (ljm+90) was later renamed PSR J1744−2444 and suspected of not being associated with Terzan 5 (lmbm00). This is confirmed by the DM distribution of subsequent discoveries in Terzan 5 (rhs+05); for this reason this pulsar is not listed below. Pulsars M3C and NGC 6749B (hrs+07) have never been confirmed, so they are not listed below, but they might still be. 47 Tuc A and B (ajm+89) have never been confirmed, their DMs are very different from those of subsequent discoveries in 47 Tuc. Pulsar 47 Tuc K (mlj+90) was later found to be the third harmonic of 47 Tuc D (rlm+95). Pulsar NGC 6517J was later found to be a harmonic of NGC 6517B. |
