a galaxy ("galactocentric cylindrical polar coordinates"). The three coordinates (ρ, φ, z) of a point P are defined as: The radial distance ρ is the Euclidean...

See Fig. 6. for a plot of the effective cluster radius versus galactocentric distance. Caldwell, N.; Strader, J.; Romanowsky, A.J.; Brodie, J.P.; Moore...

which means that it is travelling within the Milky Way at a mean galactocentric distance of 28.7 kly (8.79 kiloparsecs) from the core along an orbit that...

Milky Way galaxy of 0.30 (compared to 0.06 for the Sun.) The mean galactocentric distance for the orbit is 10.3 kiloparsecs (about 34,000 light-years). As...

published, claiming a distance of more than 5 Mpc. It was based on the infrared Tully–Fisher relation. As of 2011, the distance to Dwingeloo 1 is thought...

Way galaxy that has an orbital eccentricity of 0.18 at a mean galactocentric distance of 8.1 kpc. The star will achieve perihelion in around 82,200 years...

(km/s)/Mpc to estimate a distance of 16.8 Mpc to NGC 4569. Adjusting for the 2006 value of 70+2.4 −3.2 (km/s)/Mpc we get a distance of 18.0+0.9 −0.6 Mpc....

larger than the red ones at the same galactocentric distance, while the size of the clusters increases with galactocentric radius. NGC 4278 has been identified...

the distance to the star can be measured. The stars lie at the distance of 3,070×10^3 ± 240×10^3 ly (941 ± 74 kpc). The average of 102 distance estimates...

241 km/s. The visible radius of Dwingeloo 2 is approximately 2′, which at the distance of 3 Mpc corresponds to about 2 kpc. Dwingeloo 2 has a well defined rotating...

using this technique gave distances of 30.6 ± 1.3 Mly (9,380 ± 400 kpc). Later, after some refinement of the technique, a distance of 32 ± 3 Mly (9,810 ± 920 kpc)...
