Cinemática y Dinámica de Galaxias Espirales /
(2010-03)
Esta tesis estudia la relación entre la cinemática y el brillo superficial en una muestra de galaxias espirales, poniendo especial atención en las incertezas involucradas para poder interpretar las observaciones en términos ...
Estudios estadísticos en entornos de galaxias /
(2011-03)
En este trabajo de Tesis se presentan los resultados provenientes de análisis estadísticos de galaxias en diferentes medios.
Utilizando información de los redshifts fotométricos obtenidas a través de redes neuronales para ...
Función de luminosidad de galaxias a partir de corrimientos al rojo fotométricos
(2014-12)
En el presente trabajo se realiza un análisis de la estima de la Función de Luminosidad (FL) de galaxias a partir del uso de redshifts fotométricos como estimadores de distancias. Se estudian dos métodos para estimar la ...
Effects of the explosion asymmetry and viewing angle on the Type Ia supernova colour and luminosity calibration
(2011)
Phenomenological relations exist between the peak luminosity and other observables of type Ia supernovae (SNe~Ia), that allow one to standardize their peak luminosities. However, several issues are yet to be clarified: ...
Carbon Stars in the Large Magellanic Cloud: Luminosities, Colors, and Implications for the History of Star Formation
(1996-12)
We present RI and JHK photometry for 888 and 204 carbon (C) stars, respectively, of the 1035 C stars found by Blanco and his collaborators in 52 fields of the Large Magellanic Cloud (LMC). The results of our analysis of ...
Color-Magnitude Relations of Active and Non-active Galaxies in the Chandra Deep Fields: High-redshift Constraints and Stellar-mass Selection Effects
(2010)
We extend color-magnitude relations for moderate-luminosity X-ray AGN hosts and non-AGN galaxies through the galaxy formation epoch in the Chandra Deep Fields. We utilized analyses of color-magnitude diagrams (CMDs) to ...
The Color-Magnitude Relation for Metal-Poor Globular Clusters in M87: Confirmation from Deep HST/ACS Imaging
(2009)
Metal-poor globular clusters (GCs) are our local link to the earliest epochs of star formation and galaxy building. Studies of extragalactic GC systems using deep, high-quality imaging have revealed a small but significant ...
