Context. Empirical libraries of stellar spectra play an important role in different fields. For example, they are used as reference for the automatic...
Counting stars from the integrated spectra of galaxies
Over the last few decades, evolutionary population synthesis models have powered an unmatched leap forward in our understanding of galaxies. From dating the age...
Counts-in-cylinders in the Sloan Digital Sky Survey with Comparisons to N-body Simulations
Environmental statistics provide a necessary means of comparing the properties of galaxies in different environments, and a vital test of models of galaxy...
Covariance matrices for variance-suppressed simulations
Cosmological N-body simulations provide numerical predictions of the structure of the Universe against which to compare data from ongoing and future surveys...
Lenticular galaxies (S0s) represent the majority of early-type galaxies in the local Universe, but their formation channels are still poorly understood. While...
Cross-correlation of SDSS DR7 Quasars and DR10 BOSS Galaxies: The Weak Luminosity Dependence of Quasar Clustering at z ~ 0.5
We present the measurement of the two-point cross-correlation function (CCF) of 8198 Sloan Digital Sky Survey Data Release 7 quasars and 349,608 Data Release 10...
Crucial aspects of the initial mass function. II. The inference of total quantities from partial information on a cluster
Context. In a probabilistic framework of the interpretation of the initial mass function (IMF), the IMF cannot be arbitrarily normalized to the total mass, ℳ...
Recent observations of galaxy luminosity profiles and dark matter simulations find luminosity and mass distributions characterized by central cusps rather than...
CUYS survey of Ha+NII ELG galaxies (Bongiovanni+, 2005)
The CUYS is being carried out on the 1-m Schmidt telescope located at the Venezuelan National Astronomical Observatory, Llano del Hato, Merida, Venezuela...
