Cut-off radii of galactic disks. A new statistical study on the truncation of galactic disks.

POHLEN M., DETTMAR R.-J. and LUETTICKE R.

Abstract (from CDS):

We present the analysis of a CCD survey of 31 nearby (≤110Mpc) edge-on spiral galaxies. The three-dimensional one-component best fit models provide their disk-scalelengths h and for the first time their disk cut-off radii Rco. We confirm for this sample the existence of such sharp truncations, and find a significantly lower mean value of the distance independent ratio Rco/h=2.9±0.7 than the standard value of 4.5 often used in the literature. Our data show no correlation of these parameters with Hubble type, whereas we report a correlation between Rco/h and the distance based scalelength in linear units. Compared to the Milky Way we find only lower values of Rco/h, explained either by possible selection effects or by the completely different techniques used. We discuss our data in respect to present models for the origin of the cut-off radii, either as a relict of the galaxy formation process, or as an evolutionary phenomenon.

within arcsec The VizieR photometry tool allows for easy visualization of photometry points extracted around the Simbad position from photometry-enabled catalogues in VizieR.
The search radius has to be specified by the user. It is currently limited to a maximum of 30 arcsec. It depends mostly on the precision or quality of the coordinates (SIMBAD and VizieR catalogs), the resolution of the images from which the sources were extracted, source extent, and source crowding.
Suggestions are: crowded field: 0.5 to 1.5 arcsec, 3 arcsec otherwise; uncertain coordinates (SIMBAD quality E or coordinates without reference): 5 to 30 arsec (risky!). sed-help-icon
