Leo Triplet (mosaic)

Triplet de Leo (mosaic)

Aprofitant les fotografies de m65-66 i de NGC 3628 he fet aquest mosaic amb MaximDL i processat amb PixInsight.

És una combinació de dues peces.

A 100% de resolució es veuen els defectes… peró al 50% dona el pego 😉

NGC 3628 and questions on dark matter models

Sobre NGC3628:

NGC 3628 is an unbarred spiral galaxy about 35 million light-years away in the constellation Leo. It was discovered by William Herschel in 1784. It has an approximately 300,000 light-years long tidal tail. NGC 3628 along with M65 and M66 form the famous Leo Triplet, a small group of galaxies. Its most conspicuous feature is the broad and obscuring band of dust located along the outer edge of its spiral arms, effectively transecting the galaxy to our view.

Sobre Leo Triplet:

The Leo Triplet (also known as the M66 Group) is a small group of galaxies about 35 million light-years away[citation needed] in the constellation Leo. This galaxy group consists of the spiral galaxies M65, the M66, and the NGC 3628.

The table below lists galaxies that have been consistently identified as group members in the Nearby Galaxies Catalog[3], the Lyons Groups of Galaxies (LGG) Catalog[1], and the group lists created from the Nearby Optical Galaxy sample of Giuricin et al.[2].

Members of the Leo Triplet
Name Type[5] R.A. (J2000)[5] Dec. (J2000)[5] Redshift (km/s)[5] Apparent Magnitude[5]
M65 SAB(rs)a 11h 18m 56.0s +13° 05′ 32″ 807 ± 3 10.3
M66 SAB(s)b 11h 20m 15.0s +12° 59′ 30″ 727 ± 3 9.7
NGC 3628 SAb pec 11h 20m 17.0s +13° 35′ 23″ 843 ± 1 9.4

Additionally, some of the references cited above indicate that one or two other nearby galaxies may be group members. NGC 3593 is frequently but not consistently identified as a member of this group.
