Spiral galaxies are typically classified as star-forming, which is associated with their blue color. They are usually found in less dense regions. Their counterparts, red elliptical galaxies, which are usually passive, are typically found in overdense regions. Red and disk-like galaxies, on the other hand, are passive but retain a spiral disk structure. These galaxies are relatively rare, and...
The standard pipeline and deblender for LSST use techniques that are not ideal to the characterization of Low Surface Brightness galaxies and features. Of particular concern and interest to us, are issues of shredding and improper centroiding for LSB galaxies which leads to the standard pipeline catalogs becoming unreliable when searching for these objects. The alternative of re-doing the...
