Evidence against the association of PSR B1706-44 with SNR G343.1-2.3 . ... Abstract An association between the supernova remnant SNR G343.1-2.3 and the pulsar PSR B1706-44 would imply a pulsar velocity greater than 1000 km/s. Observations of the pulsar scintillation made with the Parkes radio telescope at 20 and 70 cm indicate a velocity less than 50 km/s. This fact, coupled with statistical arguments and the morphology of both the SNR and the pulsar plerion, shows that the ...

... A major part of my PhD thesis consisted of distance measurements to early-type galaxies in the Hydra and Centaurus clusters ( Mieske et al. 2005 , see the two figures below). ... The results of our distance measurements implied a significant peculiar velocity of the Hydra cluster , and a negligible peculiar velocity for Centaurus . This finding is consistent with a massive Great Attractor (~10^16 M_sun) at 45-50 Mpc distance, closer in projection to Hydra than to Centaurus . ...
