M32p

[edit]

Should link to M32p and mention D'Souza and Bell. Also, D'Souza and Bell predict that the collision happened 2 billion years ago, which is newer info than the possibly outdated 800 million year mention in the article.

Redshift?

[edit]

Are the given redshifts here and in other pages about galaxies from the Local Group earth-centric, heliocentric, or barycenter-centric? —Preceding unsigned comment added by 87.126.159.205 (talk) 05:48, 28 May 2009 (UTC)[reply]

Missing references stating that M32 is a dwarf elliptical?

[edit]

I have not seen any literature indicating that M32 is a dwarf elliptical (dE). In fact I have only seen indication that it is not a dE, but rather a very rare, dim, compact elliptical (cE).

The website from Caltech referenced in the article here: http://nedwww.ipac.caltech.edu/forms/byname.html states that M32 is a type cE3 galaxy, and in the book 'Galaxies in The Universe' by L. S. Sparke and J. S. Gallagher they make a clear distinction between M32 (which they call a rare compact elliptical) and dwarf ellipticals citing that M32 has 'appreciable rotation' compared to dE's and dSph.

You can see the discussion by Sparke and Gallagher in the Google preview of their book here: http://books.google.com/books?id=N8Hngab5liQC&lpg=RA1-PA251&dq=galaxie%20sin%20the%20universe&pg=RA1-PA248#v=onepage&q=&f=false Askielboe (talk) 21:36, 24 October 2009 (UTC)[reply]

Distance question

[edit]

Hi all. Just wondering about something as it does not make sense to me, but I do not want to update something incorrectly. In the beginning of the article it says

about 2,650,000 light-years (810,000 pc) from the Solar System, appearing in the constellation Andromeda.

Yet the info box says

Distance 2.49 ± 0.08 Mly (763 ± 24 kpc)

And then there's the entire section about distance:

Distance measurements At least two techniques have been used to measure distances to M32. The infrared surface brightness fluctuations distance measurement technique estimates distances to spiral galaxies based on the graininess of the appearance of their bulges. The distance measured to M32 using this technique is 2.46 ± 0.09 million light-years (755 ± 28 kpc). However, M32 is close enough that the tip of the red giant branch (TRGB) method may be used to estimate its distance. The estimated distance to M32 using this technique is 2.51 ± 0.13 million light-years (770 ± 40 kpc). For several additional reasons, M32 is thought to be in the foreground of M31, rather than behind. Its stars and planetary nebulae do not appear obscured or reddened by foreground gas or dust. Gravitational microlensing of M31 by a star in M32 was observed at the end of November 2000 in one event (with peak on 2 december 2000).

Why so many different measurements in the same article? Chupon (talk) 18:52, 8 September 2023 (UTC)[reply]
