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…
