SUMMARY

Researchers often refer to "XX-band selected galaxies" to denote galaxies identified based on specific wavelength criteria, such as the 250μm wavelength used by D.J.B. Smith et al. in their analysis of 250μm-selected galaxies at redshift z < 0.5. This selection process involves detecting galaxies with instruments tuned to particular wavelengths, confirming that only those galaxies meeting the specified criteria are included in the study. Similarly, "mass selected galaxies" indicates that the selection is based on the mass of the galaxies, further emphasizing the criteria-based approach in galaxy surveys.

PREREQUISITES
  • Understanding of galaxy surveys and their methodologies
  • Familiarity with redshift concepts in astrophysics
  • Knowledge of photometric selection techniques in astronomy
  • Basic grasp of galaxy mass measurement techniques
NEXT STEPS
  • Research the principles of photometric selection in galaxy surveys
  • Learn about the significance of redshift in astronomical observations
  • Explore techniques for measuring galaxy mass
  • Investigate the implications of wavelength selection on galaxy properties
USEFUL FOR

Astronomers, astrophysics students, and researchers involved in galaxy surveys and selection criteria methodologies will benefit from this discussion.

Hi all,

I'm hoping a pretty simple question. When I read about researchers working on galaxy surveys, they often state they're working on "XX-band selected galaxies". For example, D.J.B. Smith et al. performed analysis on a large number of 250μm-selected galaxies at z < 0.5.

Is this as simple as it sounds - that they selected only galaxies that were detected with their 250μm instrument?

Thanks!

Along the same lines, I've seen a few "mass selected galaxies" as well. So I'm assuming that the researcher has selected a pool of galaxies using wavelength (above example) or mass (this example) as the criteria.

Can anyone confirm?
 
come on guys :rolleyes: …

someone must know the answer to this! :smile:​
