This article was created with good intentions to be a quick reference page listing all known and probable black hole stars; I will commit to clarifying and expanding this article, and I look forward to our joint effort to improve this article. Take care. ProfessorPaul ( talk) 01:46, 19 July 2009 (UTC)
Candidates should be placed on List of black hole candidates. --- cymru lass (hit me up)⁄ (background check) 21:18, 2 October 2010 (UTC)
Could we incorporate a new section "black holes by distance from Sol", or include it distance in the listing? It's trivial, but I'm curious. samwaltz ( talk) 03:54, 21 November 2010 (UTC)
I, too, am curious to know relative & actual distances from Earth/Sun to black holes, and I think adding that information to this page would greatly increase its utility & popularity. But rather than duplicating the existing list with a reorganized one, I suggest adding sort options to the current list. This would also solve the issue of "confirmed" vs. "candidate" by offering that sort option. Steve8394 ( talk) 19:55, 29 November 2014 (UTC)
This page should not be speedily deleted because... (your reason here) -- 24.34.11.217 ( talk) 20:53, 31 March 2015 (UTC) there is a galaxy in the page.
This section needs updating. Two others have been found, one is a duplicate, and five (listed as mass unknown below) can be considered extremely tentative because all that is known about them is that they are a bright X-ray source that is not a supermassive black hole. Best masses are listed in the following table.
In the Milky Way
2,200 – 47 Tucanae – a star cluster 16,700 light years from Earth
198 – 1E1740.7-2942 (Great Annihilator), 340 LY from Sgr A* – a confirmed black hole near the centre of the Milky Way
100,000 – CO-0.40-0.22 – this is a possible black hole near the centre of the Milky Way
1,300 – GCIRS 13E – this is a possible black hole near the centre of the Milky Way
mass unknown – Messier 15 (NGC 7078) – a globular cluster 33,600 light-years from Earth – black hole not yet confirmed
In other galaxies
500 – HLX-1 – located in the galaxy ESO 243-49
400±100 – M82 X-1
200 to 5,000 – Cigar Galaxy (Messier 82, NGC 3034) – this is a duplicate entry, it is the same as M82 X-1.
20,000 – “Michael Rich of the University of California at Los Angeles found a 20,000 solar mass black hole in a cluster in the Andromeda Galaxy, 2.2 million light years away”. “The globular cluster G1 (Mayall II) in M31 has been claimed to host a central ~20,000 M☉ black hole, but these claims have been controversial.”
mass unknown – Messier 110 (NGC 205) – companion of Andromeda galaxy, black hole not yet confirmed
mass unknown – NGC 1313 X-1 – black hole not yet confirmed
mass unknown – NGC 1313 X-2 – black hole not yet confirmed
mass unknown – Sculptor Galaxy (NGC 253) – unidentified X-ray source near but not at the galaxy centre
mass unknown <3,000 – Triangulum Galaxy (Messier 33, NGC 598) – unidentified X-ray source at the galaxy centre Mollwollfumble ( talk) 22:56, 9 February 2017 (UTC)
