Alex Echeverría publishes his first paper on an important Journal

Alumnus Alex Echeverria published on October 21st in the prestigious Journal "Astronomy & Astrophysics". The news were spread by several local media, which gave big relevance to the topic.
The work titled "Analysis of the Bayesian Cramér-Rao lower bound in astrometry: Studying the impact of prior information in the location of an object" was developed in an interdisciplinary effort by Alex Echeverria as his undergraduate thesis, Jorge Silva and Marcos Orchard, associate proffessors in the Electrical Engineering Department and René Méndez, associate professor in the Astronomy Department and research associate in Instituto Milenio de Astrofísica. They decided to change the approach of estimating objects position in space by creating a tool which allows to improve and quantify the precision of the acquired information of astronomical observation, but not from the quality of the instruments but from mathematics, making use of data usually lost in the sea of information obtained in each astronomical observation. Using the results from the so-called Bayesian Theory of Probabilities, the experts created a tool which allows the re-use of information previously aquired and combine it with current observations in order to magnify the fidelity of the resulting data.
