... Simply count or estimate the number of redrings that it takes to fully enclose the galaxy image and use that number as your ... the redshift for each of the galaxies from your measurements in combination with the rest frame wavelengths given above ...
... UGC 6614 This galaxy is a member of the large disk class of LSB galaxies. ... has an obvious bulge and an inner ring; the outer diffuse spiral structure defines a ... The central surface brightness of this galaxy is 24.28 . ...
... We know the rest wavelength is 4861 and therefore the velocity of the galaxy (its redshift, since the line is shifted to longer wavelengths) would be: . ...
... M94 or NGc 4736 is an early type spiral galaxy with tightly would spiral structure and a dominant, luminous central bulge. ... There is a prominent ring of star formation that is somewhat visible but overexposed in this CCD image. ...
... determined and calibrated the Cepheid Period-Luminosity relation and have used it to find distances to some nearby galaxies ... m-M) LMC : (18.35 -- 18.50). Cepheid vs. RR Lyrae zeropoint discrepancy; SN 1987 Ring . M100 and depth. ...
... It may be that the LSB galaxies we observe are going through a phase of more active starformation, as is suggested by the partial star forming rings observed in a few galaxies. ...
... When the universe has cooled to the point where kT is equal to the rest mass energy of the neutrino, whatever that is ( In other words, the halo of our galaxy has a velocity dispersion of 300 km/s. A cluster of galaxies has a velocity dispersion of 1000 ...
... This first one was 720 seconds through the A1 filter. NGC 3351 is a mostly face-on late type spiral galaxy. ... It is marked by a bar like feature in its central regions and a strong inner ring of star formation. ...
... object in this field is 3-5, and thus we are seeing rest frame ultraviolet emission, redshifted into the Hubble filter set ... There are also examples of fully formed galaxies (i.e. regular spiral pattern). ...
