Galaxy located in the constellation Sextans
PGC 29820 (known asJO204 ) is aspiral galaxy 600 millionlight-years from the Solar System, in theSextans constellation .[ 1] galaxy cluster .[ 2] Catalogue of Galaxies and of Clusters of Galaxies compiled byFritz Zwicky in 1961, where it was listed asCGCG 008-077 .[ 3]
PGC 29820 is classified a massive galaxy with astellar mass of M* = 4 x1010 M.[ 4] active galactic nucleus with double-peaked narrow lines.[ 5] [ 6] Seyfert 2 galaxy .[ 7]
PGC 29820 is classified ajellyfish galaxy .[ 8] [ 9] [ 10] ram pressure by theintracluster medium .[ 2]
Because dense gas is compressed, it eventually collapses to form newstars in both the galaxy's tail and its disk.[ 4] star formation rate of 0.22 M○ yr1 [ 11] [ 2]
In additional, PGC 29820 shows a large presence ofmolecular gas making up H2 mass of 8.3 x 109 M○ . Looking atratio of total molecularhydrogen mass and stellar mass, it is estimated as 0.42.[ 12]
