Annotated View: Antlia Galaxy Cluster (Abell S0636) - Extreme Deep Field - 152 Hours
This annotated image is an attempt to label every confirmed member of the Antlia Cluster in the field of view. A total of 157 members are identified and the markers seem to correlate well with visible galaxies in the field. The faintest member galaxies are ultra-faint dwarfs with magnitudes ranging from 19 to 22. Many more galaxies are visible in the background but these are more distant and not members of the Antlia Cluster.
Several custom data extracts from VizieR were necessary to accurately label the member galaxies of the cluster:
- NGC/IC: Brighter cluster members from the NGC/IC catalogues
- PGC: Fainter members (to magnitude 18) present in the PGC HYPERLEDA I catalog of galaxies
- FS90: Cluster members identified by the FS90 catalogue (Ferguson & Sandage 1990)
- ANTL: Custom extract covering faint dwarf galaxies from Castelli, A. V. S., Cellone, S. A., Faifer, F. R., Bassino, L. P., Richtler, T., Romero, G. A., ... & Caso, J. P. (2012). Galaxy populations in the Antlia cluster–III. Properties of faint early-type galaxies. Monthly Notices of the Royal Astronomical Society, 419(3), 2472-2488.
Each extract was imported into PixInsight as a custom catalogue and annotation layers were generated and overlaid on the original colour image.
