UGC 711 is a relatively nearby spiral galaxy located in the constellation of Cetus. Estimated to be located 77 million light-years from Earth, [1] the galaxy's luminosity class is IV and it has a HI line width region.[ clarification needed ] [2] It belongs to the equatorial region of Eridanus Void with an arcsec approximation of ≈ 250.[ clarification needed ] [3]

Morphology

UGC 711 is considered a low-surface brightness galaxy (LSB) [4] with a diffuse stellar disk. [5] [6]

With a surface brightness measurement found ~1 magnitude less illuminated compared to μ B,0 = 21.65 mag arcsec−2 according to K.C. Freeman, [7] UGC 711 is one of best studied superthin galaxies defined by its atypical classification when seen edge-on. [8] [9] [10] It has a flat structure with only a diameter estimating to be a = 40 arcsecs but has a major-to-minor axis ratio wider than 7 arcsecs. [11]

The rotational velocity of UGC 711 is said to be only Vcirc = 92 km s−1 according to measurements from Hyperleda. [12]

<span class="mw-page-title-main">Galaxy formation and evolution</span>

The study of galaxy formation and evolution is concerned with the processes that formed a heterogeneous universe from a homogeneous beginning, the formation of the first galaxies, the way galaxies change over time, and the processes that have generated the variety of structures observed in nearby galaxies. Galaxy formation is hypothesized to occur from structure formation theories, as a result of tiny quantum fluctuations in the aftermath of the Big Bang. The simplest model in general agreement with observed phenomena is the Lambda-CDM model—that is, clustering and merging allows galaxies to accumulate mass, determining both their shape and structure. Hydrodynamics simulation, which simulates both baryons and dark matter, is widely used to study galaxy formation and evolution.

<span class="mw-page-title-main">Thick disk</span> Structural component of some galaxies

The thick disk is one of the structural components of about 2/3 of all disk galaxies, including the Milky Way. It was discovered first in external edge-on galaxies. Soon after, it was proposed as a distinct galactic structure in the Milky Way, different from the thin disk and the halo in the 1983 article by Gilmore & Reid. It is supposed to dominate the stellar number density between 1 and 5 kiloparsecs above the galactic plane and, in the solar neighborhood, is composed almost exclusively of older stars. Its stellar chemistry and stellar kinematics are also said to set it apart from the thin disk. Compared to the thin disk, thick disk stars typically have significantly lower levels of metals—that is, the abundance of elements other than hydrogen and helium.
