Cosmology with the Space-Luminosity Distribution of Virialized Halos
Christian Marinoni, Michael J. Hudson, Giuliano Giuricin
We derive the observed luminosity function of virialized systems. Coupling this statistic with the mass function predicted by CDM cosmogonies we obtain the functional behavior of t…
Clustering of Galaxies and Groups in the NOG Sample
G. Giuricin, S. Samurovic, M. Girardi +2
We use the two-point correlation function in redshift space, , to study the clustering of the galaxies and groups of the Nearby Optical Galaxy (NOG) Sample, which is a nearly…
The NOG Sample: Galaxy Systems and 3D Real-Space Galaxy Density
C. Marinoni, G. Giuricin, L. Ceriani +1
We discuss the 3D real-space reconstruction of the optical galaxy density field in the local Universe as derived from the galaxies of the Nearby Optical Galaxy (NOG) sample. NOG is…
The NOG Sample: 3D Reconstruction of the Real-Space Density Field
C. Marinoni, G. Giuricin, L. Ceriani
We discuss the real-space reconstruction of the optical galaxy density field in the local Universe (cz < 6000 km/s) as derived from the 7076 galaxies of the Nearby Optical Galaxy (…
The NOG Sample: Selection of the Sample and Identification of Galaxy Systems
G. Giuricin, C. Marinoni, L. Ceriani +1
In order to map the galaxy density field in the local universe, we select the Nearby Optical Galaxy (NOG) sample, which is a distance-limited (cz < 6000 km/s) and magnitude--limite…
The Galaxy Luminosity and Selection Functions of the NOG Sample
C. Marinoni, G. Giuricin, B. Costantini +1
In order to map the galaxy density field on small scales in the local universe, we use the Nearby Optical Galaxy (NOG) sample, which is currently one of the largest, nearly complet…
