The Barolo Palace: medieval astronomy in the streets of Buenos Aires
(University Wales Trinity Saint David. The Sophia Centre for the Study of Cosmology in Culture, 2013-04)
Cultural heritage relating to the sky in the form of sundials, old observatories and the like, are commonly found in many cities in the Old World, but rarely in the New. This paper examines astronomical heritage embodied ...
Redshift-space effects in voids and their impact on cosmological tests. Part I: The void size function
(Wiley Blackwell Publishing, Inc, 2021-01)
Voids are promising cosmological probes. Nevertheless, every cosmological test based on voids must necessarily employ methods to identify them in redshift space. Therefore, redshift-space distortions (RSD) and the ...
Non-fiducial cosmological test from geometrical and dynamical distortions around voids
(Wiley Blackwell Publishing, Inc, 2019-03)
We present a new cosmological test using the distribution of galaxies around cosmic voids without assuming a fiducial cosmology. The test is based on a physical model for the void-galaxy cross-correlation function projected ...
Improving the precision matrix for precision cosmology
(Oxford University Press, 2015-12)
The estimation of cosmological constraints from observations of the large-scale structure of the Universe, such as the power spectrum or the correlation function, requires the knowledge of the inverse of the associated ...
Cosmología en la obra de Dante Alighieri
(Universidad del RosarioFilosofíaEscuela de Ciencias Humanas, 2012)
This essay try to show the synthesis beetween the greek cosmological traditiona and the middle ages reception, through the Dante Alighieri´s work
The sparkling Universe: clustering of voids and void clumps
(Wiley Blackwell Publishing, Inc, 2017-07)
We analyse the clustering of cosmic voids using a numerical simulation and the main galaxy sample from the Sloan Digital Sky Survey. We take into account the classification of voids into two types that resemble different ...
Cosmología en la obra de Dante Alighieri: Génesis y fuentes
(Editorial Universidad del RosarioFilosofía, 2013-12-06)
This text explores some relationships between art and science; focuses on a specific period in history: the late Middle Ages, and on one author in particular: Dante Alighieri. The selection of Dante's work as an object of ...
Contexto, consecuencias y fuentes de la doctrina dantesca “Homo est Medium” (Monarchia, III, xv)Context, Consequences and Sources of Dante’s Doctrine of the “Homo est Medium” (Monarchia, III, xv)
(Facultad de Filosofía y Letras, Universidad de Buenos Aires, 1992)
Voids and superstructures: Correlations and induced large-scale velocity flows
(Wiley Blackwell Publishing, Inc, 2017-09)
The expanding complex pattern of filaments, walls and voids build the evolving cosmic web with material flowing from underdense on to high density regions. Here, we explore the dynamical behaviour of voids and galaxies in ...
The sparkling Universe: A scenario for cosmic void motions
(Oxford University Press, 2016-10)
Cosmic voids are prominent features of the Universe, encoding relevant information of the growth and evolution of structure through their dynamics. Here, we perform a statistical study of the global motion of cosmic voids ...
