Let Qn be the random number of comparisons made by quicksort in sorting n distinct keys, when we assume that all n! possible orderings are equally likely. Known results concerning moments for Qn do not show how rare it is for Qn to make large deviations from its mean. Here we give a good approximation to the probability of such a large deviation, and find that this probability is quite small. A...

New constraints on the mass of quasars are derived from gravitational lensing studies of the QSO pairs Q1548+114 A & B and Q1148+0055 A & B, for which new ground-based and Hubble Space Telescope (HST) direct imagery have been obtained. In the case of Q1548+114 A & B, QSO A has been resolved into its host galaxy and a close companion. The nondetection with HST of a secondary lensed image of the ...

We have obtained optical intermediate resolution spectra (R = 3000) of the narrow-line quasars DMS 0059−0055 and PG 1543+489. The [O III] emission line in DMS 0059−0055 is blueshifted by 880 km s relative to Hβ. We also confirm that the [O III] emission line in PG 1543+489 has a relative blueshift of 1150 km s. These two narrow-line quasars show the largest [O III] blueshifts known to date amon...
