NGC 5532
galaxy
NGC 5532 is an elliptical galaxy located in the constellation Boötes. It is located at a distance of about 250 million light years from Earth, which, given its apparent dimensions, means that NGC 5532 is about 110,000 light years across. It was discovered by William Herschel on March 15, 1784. It is a Fanaroff–Riley type 1 (FR1) radio galaxy.
NGC 5532 is an elliptical galaxy located in a galaxy group. In the centre of the galaxy lies a warped disk, while the isophotes display boxiness and the centre of the galaxy doesn't coincide with the isophotal centre. The core appears obstructed in X-rays, with a column density of (1.0±0.5)×1022 cm−2, which is considered high for a FR1 galaxy. In the centre of the galaxy lies a supermassive black hole whose mass is estimated to be 108.8 (630 millions) M☉ based on the M–sigma relation.
Two straight radio jets emerge from the galaxy core and form sharp edged lobes that appear to engulf the jets, although this could be a projection effect. The jets are typical of a Fanaroff–Riley type 1 radio galaxy, with faint bases that brighten abruptly 2.7 arcseconds from the nucleus and then the brightness gets lower at the distance from the core increases.
Begin with the source’s own compact description: “NGC 5532” is galaxy. The dossier treats that line as a proposition to test through galaxy, not as a finished interpretation.
Why this record matters
The phrase “galaxy” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 3, 2026. The linked authority identifier is Q1120805. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1784 and 1022.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
