Discovery of a Giant, Highly Collimated Jet from Sanduleak's Star in the Large Magellanic Cloud
(2011)
Highly-collimated gas ejections are among the most dramatic structures in the Universe, observed to emerge from very different astrophysical systems - from active galactic nuclei down to young brown dwarf stars. Even with ...
Producción de neutrones en jets de microcuásares: inyección de partículas relativistas en el medio circundante
(Asociación Argentina de Astronomía, 2020-07)
The composition and launching mechanism of astrophysical jets are open problems in the relativistic astrophysics area, though not at all independent as comes up from the proposed launching models. To study the jet composition ...
Radiative models for jets in X-ray binaries
(Paideia, 2013)
In this work we develop a lepto-hadronic model for the electromagneticradiation from jets in microquasars with low-mass companionstars. We present general results as well as applications to somespecific systems, and carefully ...
Real-time evolution of a large-scale relativistic jet
(Edp Sciences, 2015-06)
Context. Astrophysical jets are ubiquitous in the Universe on all scales, but their large-scale dynamics and evolution in time are hard to observe since they usually develop at a very slow pace. Aims. We aim to obtain the ...
Evolução de Rádio Fontes Duplas Extragalácticas
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em FísicaFísica da Matéria Condensada; Astrofísica e Cosmologia; Física da Ionosfera, 2010-06-28)
Double radio sources have been studied since the discovery of extragalactic radio sources in the decade of 1930. Since then, several numerical studies and analytical models have been proposed seeking a better understanding ...
Neutron escape from microquasar jets
(Asociación Argentina de Astronomía, 2020-08)
The launching mechanism and composition of astrophysical jets are still open problems. If relativistic protons are present in these jets, then energetic neutrons should be produced. Since neutrons are not affected by ...

MODELING VERY LONG BASELINE INTERFEROMETRIC IMAGES WITH THE CROSS-ENTROPY GLOBAL OPTIMIZATION TECHNIQUE
(IOP PUBLISHING LTD, 2011)
We present a new technique for obtaining model fittings to very long baseline interferometric images of astrophysical jets. The method minimizes a performance function proportional to the sum of the squared difference ...
Astrophysical jets from boosted compact objects
(American Physical Society, 2019-09)
We perform full 3D numerical simulations of compact objects, such as black holes or neutron stars, boosted through an ambient forcefree plasma that posses a uniform magnetization. We study jet formation and energy extraction ...
