Detection of Gravitational Redshift in Open Cluster non-degenerate stars
Carlos M. Gutiérrez, Nataliya Ramos-Chernenko
A key observational prediction of Einstein's Equivalence Principle is that light undergoes redshift when it escapes from a gravitational field. Although astrophysics provides a wid…
Constraint on the time variation of the fine-structure constant with the SDSS-III/BOSS DR12 quasar sample
Franco D. Albareti, Johan Comparat, Carlos M. Gutiérrez +9
From the Sloan Digital Sky Survey (SDSS) Data Release 12, which covers the full Baryonic Oscillation Spectroscopic Survey (BOSS) footprint, we investigate the possible variation of…
A study of the galaxy redshift distribution toward the cosmic microwave background cold spot in the Corona Borealis supercluster
Ricardo Génova-Santos, Carmen P. Padilla-Torres, José Alberto Rubiño-Martín +2
We present a study of the spatial and redshift distributions of Sloan Digital Sky Survey (SDSS) galaxies toward the position of CrB-H, a very deep and extended decrement in the Cos…
Weather at Sierra Negra: 7.3-year statistics and a new method to estimate the temporal fraction of cloud cover
E. Carrasco, A. Carramiñana, R. Avila +5
Sierra Negra, one of the highest peaks in central Mexico, is the site of the Large Millimeter Telescope. We describe the first results of a comprehensive analysis of the weather da…
Motion properties of satellites around external spiral galaxies
M. Azzaro, F. Prada, C. M. Gutiérrez
We are analyzing a sample of closeby galaxy systems, each comprising a bright isolated spiral and its satellites. We find an excess (56%) of prograde satellites over retrograde, wh…
