Visualizing 3D Astronomical Data Cubes from Radio Telescopes: Spiral Galaxy NGC 6946
Показать описание
NGC 6946 is a SAB spiral galaxy between the constellations Cygnus and Cepheus.
If we observe a spiral galaxy with the NRAO Karl G. Jansky Very Large Array we can obtain information about its three-dimensional dynamic structure.
The spectral line observed here is that of the 1420 MHz neutral hydrogen line.This radio data cube shows right ascension and declination sky axes, as well as a third axis of frequency. This 3D rendering of the data seen here shows the dynamic structure and rotation of this spiral galaxy.
The National Radio Astronomy Observatory is a facility of the National Science Foundation operated under cooperative agreement by Associated Universities, Inc.
