Update of membership and mean proper motion of open clusters from UCAC5 catalog
W. S. Dias, H. Monteiro, M. Assafin
We present mean proper motions and membership probabilities of individual stars for optically visible open clusters, which have been determined using data from the UCAC5 catalog. T…
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…
Fitting Isochrones to Open Cluster photometric data: A new global optimization tool
H. Monteiro, W. S. Dias, T. C. Caetano
We present a new technique to fit color-magnitude diagrams of open clusters based on the Cross-Entropy global optimization algorithm. The method uses theoretical isochrones availab…
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…
