Line width velocity
NettetThe phase velocity and propagation constant is given by: With the effective dielectric constant, εe of the microstrip line satisfying the relation: The more complex formulas for effective dielectric constant, characteristic impedance, surface resistivity of conductor and attenuation on the line are given in [1]. The Model NettetZero velocity is then defined for that redshift and is therefore intrinsic to the object. This method will appropriately apply the redshift correction to the channel and line widths and the resulting velocities are also relative to the source. Note that the VLA's natural spectral axis is in frequency.

NettetBroadening of Spectral Lines In the study of transitions in atomic spectra, and indeed in any type of spectroscopy, one must be aware that those transitions are not precisely "sharp".There is always a finite width to the observed spectral lines. One source of broadening is the "natural line width" which arises from the uncertainty in energy of the … When a particle moves (e.g., due to the thermal motion) towards the observer, the emitted radiation is shifted to a higher frequency. Likewise, when the emitter moves away, the frequency is lowered. For non-relativistic thermal velocities, the Doppler shift in frequency is where is the observed frequency, is the rest frequency, is the velocity of the emitter towards the observer, and is the speed of light.

The solid line represents the relation FWHM = 2.12σ. … In astronomy, the velocity dispersion (σ) is the statistical dispersion of velocities about the mean velocity for a group of astronomical objects, such as an open cluster, globular cluster, galaxy, galaxy cluster, or supercluster. By measuring the radial velocities of the group's members through astronomical spectroscopy, the velocity dispersion of that group can be estimated and used to derive the group's mass from the virial theorem. Radial velocity is found by measuring the Doppl…
