Description
NED service to retrieve Quantities Derived from Redshift for a named object:
The NASA/IPAC Extragalactic Database (NED) provides a comprehensive fusion
of multi-wavelength data for hundreds of millions of objects located beyond
the Milky Way galaxy.
This service retrieves quantities derived from redshift for a named object.
The following quantities are provided:
- Calculated and corrected velocities: Heliocentric, Kinematic LSR,
Galactocentric GSR, Local Group, 3K CMB, Virgo Infall, Virgo plus
Great Attractor, Virgo + Great Attractor + Shapley Concentration
- Hubble flow distance and distance modulus: applying the same
corrections noted above, the Hubble distance in Mpc and the distance
modulus in (m - M) magnitude units are provided
- Scale at Hubble flow distance: applying the same corrections noted
above, the scale is provided in units of pc/arcsec, kpc/arcsec,
kpc/arcmin, and Mpc/degree
- Cosmology-corrected quantities: Luminosity Distance [Mpc], Angular-Size
Distance [Mpc], Co-Moving Radial Distance [Mpc], Co-Moving Tangential
Distance [Mpc], Co-Moving Volume [Gpc^3], Light Travel-Time [Gyr],
Age at Redshift (of the object) [Gyr], Age of Universe [Gyr],
Scale (Cosmology Corrected) [pc/arcsec,kpc/arcsec,kpc/arcmin,Mpc/degree],
Surface Brightness Dimming [Flux Density per Unit Area, Mag per Unit Area]
