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…
