Reconstructing Orbits of Galaxies in Extreme Regions (ROGER) III: galaxy evolution patterns in projected phase space around massive X-ray clusters
Hector J. Martinez, Valeria Coenda, Hernan Muriel +2
We use the ROGER code by de los Rios et al. to classify galaxies around a sample of X-ray clusters into five classes according to their positions in the projected phase space diagr…
Local and large-scale effects on the astrophysics of void-galaxies
Agustín M. Rodríguez-Medrano, Dante J. Paz, Federico A. Stasyszyn +3
Galaxies in cosmic voids have been reported with properties related to a delayed evolution with respect to the Universe in general. These characteristics reflect the interaction of…
Guess the cheese flavour by the size of its holes: A cosmological test using the abundance of Popcorn voids
Dante J. Paz, Carlos M. Correa, Sebastián R. Gualpa +4
We present a new definition of cosmic void and a publicly available code with the algorithm that implements it. Underdense regions are defined as free-form objects, called popcorn…
How do galaxies populate halos in extreme density environments? An analysis of the Halo Occupation Distribution in SDSS
Ignacio G. Alfaro, Facundo Rodriguez, Andrés N. Ruiz +2
Recent works have shown that the properties of galaxy populations in dark matter halos vary with large-scale environments. These results suggest a variation in the halo occupation…
