IRAS 05189−2524
Seyfert 2 galaxy in the constellation Lepus
IRAS 05189−2524 is a galaxy merger located in the constellation Lepus. It is located 603 million light-years away from the Solar System and has an approximate diameter of 75,000 light years.
A luminous galaxy
IRAS 05189−2524 is classified as an ultraluminous infrared galaxy (ULIRG), which is formed by two interacting gas-rich spiral galaxies that merged together. Signs left by merging process, included a single bright nucleus and an outer structure consisting one-sided extension of the inner arms, with its tidal tail formed by material ripped from the galaxies by gravitational forces.
IRAS 05189−2524 is one of the brightest local ULIRG in X-ray with a E = 2–10 keV continuum luminosity of ~1043 erg/s This tends to vary over time in which the E = 0.5–2 keV was relatively constant during the 2001-2002 observation done by XMM Newton and Chandra. But in 2006 study done by Suzaku shows it was a factor of ~30 lower. The galaxy has a power output above 10 times that of the Sun, emitting a tremendous amount of light at infrared wavelengths.
Moreover, IRAS 05189−2524 is classified an optical Seyfert 2 galaxy, presenting a hidden broadline region. A study noticed there is ~70% percent of the bolometric luminosity attributed to its active galactic nucleus, thus making it a quasar. It is represented by its dust enshrouded stage which is shed over time by the nuclei.
Begin with the source’s own compact description: “IRAS 05189−2524” is seyfert 2 galaxy in the constellation Lepus. The dossier treats that line as a proposition to test through IRAS, Seyfert and galaxy, not as a finished interpretation.
Why this record matters
The phrase “seyfert 2 galaxy in the constellation Lepus” 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 Nov 26, 2025. The linked authority identifier is Q80724638. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1043, 2001, 2002 and 2006.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
