Stellar Population Properties of ETGs in Compact Groups of Galaxies
Tatiana C. Moura, Reinaldo R. de Carvalho, Sandro B. Rembold +6
We present results on the study of the stellar population in Early-Type galaxies (ETGs) belonging to 151 Compact Groups (CGs). We also selected a field sample composed of 846 ETGs…
Spectral fluctuation analysis of ionospheric inhomogeneities over Brazilian territory Part II: E-F valley region plasma instabilities
Neelakshi J., Reinaldo R. Rosa, Siomel Savio +4
The turbulent-like process associated with ionospheric instabilities, has been identified as the main nonlinear process that drives the irregularities observed in the different ion…
Bayesian surface photometry analysis for early-type galaxies
D. H. Stalder, Reinaldo R. de Carvalho, Martin D. Weinberg +4
We explore the application of Bayesian image analysis to infer the properties of an SDSS early-type galaxy sample including AGN. We use GALPHAT (Yoon et al. 2010) with a Bayes-fact…
Planetary Kp index forecast using autoregressive models
Arian Ojeda Gonzalez, Clezio Marcos Denardini, Siomel Savio Odriozola +2
The geomagnetic Kp index is derived from the K index measurements obtained from thirteen stations located around the Earth geomagnetic latitudes between and .…
A new gravitational N-body simulation algorithm for investigation of cosmological chaotic advection
Diego H. Stalder, Reinaldo R. Rosa, José da Silve Junior +6
Recently alternative approaches in cosmology seeks to explain the nature of dark matter as a direct result of the non-linear spacetime curvature due to different types of deformati…
An alternative singularity-free cosmological scenario from cusp geometries
Reinaldo R. Rosa, Cristiano Strieder, Diego H. Stalder
We study an alternative geometrical approach on the problem of classical cosmological singularity. It is based on a generalized function w…
