             abstract = "The irregular satellites of outer planets are thought to have been 
                         captured from heliocentric orbits. The exact nature of the capture 
                         process, however, remains uncertain. We examine the possibility 
                         that irregular satellites were captured from the planetesimal disk 
                         during the early solar system instability when encounters between 
                         the outer planets occurred. Nesvorn{\'y} et al. already showed 
                         that the irregular satellites of Saturn, Uranus, and Neptune were 
                         plausibly captured during planetary encounters. Here we find that 
                         the current instability models present favorable conditions for 
                         capture of irregular satellites at Jupiter as well, mainly because 
                         Jupiter undergoes a phase of close encounters with an ice giant. 
                         We show that the orbital distribution of bodies captured during 
                         planetary encounters provides a good match to the observed 
                         distribution of irregular satellites at Jupiter. The capture 
                         efficiency for each particle in the original transplanetary disk 
                         is found to be (1.3-3.6) × 10-8. This is roughly enough to explain 
                         the observed population of jovian irregular moons. We also confirm 
                         Nesvorn{\'y} et al.'s results for the irregular satellites of 
                         Saturn, Uranus, and Neptune.",
