How many stars are in the Sculptor Dwarf Galaxy?
Nov 30, 2015 · The Sculptor Dwarf Galaxy is a small satellite Galaxy of the Milky Way. There are many such satellites galaxies and I'm trying to compile basic data on them. However, I can't find an estimate for the number of stars in the Sculptor Dwarf (and many other satellite galaxies too).
How many satellites does the Milky Way have?
Dec 10, 2019 · other: several additional ultra-faint dwarf spheroidal galaxies However: There is a much longer list of "galaxies" (over 60 items) Wikipedia's Satellite galaxies of the Milky Way Hopefully another answer will be posted discussing just how galactic these need to be to be called galaxies, and if they are all known to be gravitationally bound to ...

Nov 29, 2020 · Thus a "dwarf galaxy" would be assumed to be a galaxy of a type which is noticably smaller than galaxies of at least one other type. And in science there might possibly be an established dividing line between dwarf galaxies and ordinary sized galaxies, just as there might possibly be a diving line between ordinary sized galaxies and giant galaxies.

Apr 12, 2023 · It's a bit hard to pick an obvious "large galaxy" threshold. This is partly because most galaxy group catalogs are based on galaxy catalogs that are limited by apparent magnitude, meaning that it includes lower-luminosity galaxies at small distances but only high-luminosity galaxies at large distances.

May 22, 2021 · Recent studies show that ultra diffuse galaxies or UDGs were formed by tidally disturbed dwarf galaxies and failed L∗ galaxies. So I've been searching for the failed L∗ galaxies but can't find what it is.
How to find integrated radio flux for the 21-cm line due to HI …
Jul 7, 2023 · Suppose I have a rough estimate of HI gas content (in solar mass units) in a local dwarf galaxy located at a distance say d parsec (at some RA and Dec co-ordinates) with a half-light radius r and I am assuming a velocity width of 10-20 km/s. Now equipped with this info I need to figure out how much would be the approx integrated radio flux on ...

Sep 22, 2023 · We may be an exception for having so many satellite (or at least nearby) galaxies because the Milky Way's mass is thought to be quite high, even compared to many other major ones - but if we assume this figure is generally uniform throughout major galaxies, without considering independent dwarf galaxies, we can see that they out-populate ...

Apr 3, 2024 · Andromeda galaxy is inclined at about 77 degrees to us (where 90 degrees would be edge on) which makes it hard to reconstruct how it would look from 0 degrees. However there are various "artistic interpretations" I found this one as part of the Space Engine planetary Database Wiki page of about the Andromeda galaxy. It doesn't claim to be a ...
