A detailed interacting galaxy cluster within the constellation Virgo imaged by a darkish vitality digicam

That is RSCG 55, a compact galaxy cluster positioned about 350 million light-years away throughout the constellation Virgo. A galaxy cluster is a gaggle of as much as a number of dozen galaxies smaller than a galaxy cluster, and amongst them, a gaggle of galaxies that incorporates a number of galaxies particularly in a small space known as a compact galaxy cluster.

In keeping with the Nationwide Optical and Infrared Astronomy Laboratory (NOIRLab) on the Nationwide Science Basis (NSF), which launched the picture, RSCG 55 is a gaggle of interacting galaxies that affect one another by means of deep. Some interacting galaxies have shapes which are strongly moved by tidal forces, or have spiral arms that stretch like lengthy tails. The tidal bridges that join the galaxies within the picture are additionally created by interactions and are manufactured from stars, gasoline, and dirt. The galaxies related by this construction are named from the aspect left with the catalog names “Z 70-79”, “IC 790”, “Mrk 1325B”, and “NGC 4410”.(※).

This picture was created primarily based on observational information from the Darkish Vitality Digicam (DECam), an observational instrument put in on the Blanco 4m telescope on the Cerro Tololo Pan American Observatory in Chile. Because the title suggests, DECam is an observatory that was developed with the first goal of researching darkish vitality. Observations for the unique goal of darkish vitality analysis had been created from 2013 to 2019.

The primary photograph was revealed by NOIRLab on Could 22, 2024.

* Galaxies in every catalog have completely different names, so the identical galaxy could be known as a number of occasions (for instance, “M31”, “NGC 224”, and “LEDA 2557” all confer with the “Andromeda Galaxy”). Masu). Right here, we now have normalized the names listed within the fundamental information part of the Strasbourg Astronomical Information Middle “SIMBAD” database.
