| Name | Kind | What it is |
|---|---|---|
BLACK_HOLE_FOUND | constant | The ways a black hole was found: x-rays (from the X-rays of gas falling in), orbit (from the orbit of a companion star), microlensing (from how it bent a background star's light), stars (from stars orbiting it), gas (from gas orbiting it), masers (from water masers orbiting it), echoes (from the delay of light echoing through gas near it, "reverberation") and image (a picture of its shadow). |
BLACK_HOLE_KINDS | constant | The kinds of black hole, a small fixed list: stellar (in an X-ray binary, found by the X-rays it makes), quiet (found from the orbit of its companion star, or from how it bent the light of a star behind it, and giving off almost nothing) and supermassive (at the centre of a galaxy). |
blackHole | function | A black hole by any of its names, ignoring case, spacing, punctuation and the star after a name: Cygnus X-1, cyg x-1, HDE 226868, V404 Cyg, Sgr A*, M87, M87*, NGC 4486, or its id. |
BlackHole | type | One black hole. |
BlackHoleFound | type | How a black hole was found: one of BLACK_HOLE_FOUND. |
BlackHoleKind | type | The kind of a black hole: stellar, quiet or supermassive. |
BlackHoleMeasure | type | A number the papers give with its range: the best value, and the lowest and highest the paper allows, or only a limit. |
BlackHoleOptions | type | The options of blackHoles: all optional, and together they narrow the list. |
blackHoles | function | Every known black hole that has a place on the sky and a published mass or a published case for one: the stellar-mass ones in X-ray binaries (BlackCAT's 73 and a few more), the quiet ones (Gaia BH1, BH2 and BH3, VFTS 243, the lone black hole OGLE-2011-BLG-0462) and the supermassive ones at the centres of galaxies with a measured mass. |
BlackHoleSource | type | A paper that a fact comes from. |
BlackHoleSources | type | The papers behind each fact of a black hole: lists, empty where the fact is not known. |
