On the possibilities of high-energy neutrino production in the jets of microquasar SS433 in light of new observational data
(Elsevier Science, 2019-05)
Microquasar SS433 is composed by a supergiant star that feeds mass through a supercritical accretion disk to a ∼10 M ⊙ black hole. The latter launches two oppositely directed jets that precess with a period of 162 days. ...
Particle acceleration in the superwinds of starburst galaxies
(EDP Sciences, 2018-08)
Context. Starbursts are galaxies undergoing massive episodes of star formation. The combined effect of stellar winds from hot stars and supernova explosions creates a high-temperature cavity in the nuclear region of these ...
Sobre la aparente sobredensidad de cúmulos abiertos en la región de la supuesta galaxia enana en Canis Major
(Asociación Argentina de Astronomía, 2008-12)
We examine the nature of the Canis Major (CMa) stellar overdensity based on the fundamental parameters of the open clusters (OCs) projected in that region. We find only one OC physically located within CMa and estimate ...
Discovery of new globular clusters in the Sagittarius dwarf galaxy
(EDP Sciences, 2021-03-12)
Context. Globular clusters (GCs) are witnesses of the past accretion events onto the Milky Way. In particular, the GCs of the Sagittarius (Sgr) dwarf galaxy are important probes of an on-going merger. Aims. Our main goal ...
CAPOS: The bulge Cluster APOgee Survey: I. Overview and initial ASPCAP results
(EDP Sciences, 2021-08)
Context. Bulge globular clusters (BGCs) are exceptional tracers of the formation and chemodynamical evolution of this oldest Galactic component. However, until now, observational difficulties have prevented us from taking ...
