Modeling very long baseline interferometric images with the cross-entropy global optimization technique
Anderson Caproni, Hektor Monteiro, Zulema Abraham +2
We present a new technique for obtaining model fittings to VLBI images of astrophysical jets. The method minimizes a performance function proportional to the sum of the squared dif…

Cross-entropy optimiser: a new tool to study precession in astrophysical jets
A. Caproni, H. Monteiro, Z. Abraham
Evidence of jet precession in many galactic and extragalactic sources has been reported in the literature. Much of this evidence is based on studies of the kinematics of the jet kn…
