Reference excerpt

WISEA J110524.16+594341.2 also known as J1105+5943 and J110524.25+594342.0, is a radio galaxy located in the constellation of Ursa Major. The redshift of the galaxy is (z) 0.35 and it was first discovered from the Sixth Cambridge Survey of Radio Sources by astronomers in September 1990.

Description WISEA J110524.16+594341.2 is a red luminous galaxy residing in the WHL J110524.2+594342 galaxy cluster, with a total angular separation between it and the cluster center estimated to be just one arcsecond and a linear distance of 5.0 kiloparsecs. The nucleus is active and has been categorized as a Fanaroff-Riley Class Type II radio galaxy with a total radio luminosity of 5.60 × 1043 erg s-1 and contains a compact radio source. The total flux density calculated by the NRAO VLA Sky Survey (NVSS) is 81.00 mJy at 1.4 GHz frequencies. The absolute magnitude of the galaxy is -22.92 magnitude. A study found it is a wide angle-tail (WAT) radio galaxy. The radio spectra index between 3 GHz and 1.4 GHz is 0.7α and the total flux density is 51.95 mJy at 3 GHz frequencies. The 1.4 GHz logarithmic luminosity is 25.58 W Hz-1. A radio jet is present, with the jet opening angle estimated to be 122.5° and a jet curvature radius of 17.5 arcseconds in total. The largest angular size is 37 arcseconds, while the largest linear size is 192.0 kiloparsecs. The flux density at 1400 MHz is 89 mJy and the flux density at 150 MHz is 504 mJy.

Worked examples

Example 1 — a first encounter with WISEA J110524.16+594341.2

Start with the simplest possible case. Write down what WISEA J110524.16+594341.2 claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to WISEA J110524.16+594341.2 before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about WISEA J110524.16+594341.2 ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of WISEA J110524.16+594341.2

In research: WISEA J110524.16+594341.2 appears in astronomy research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses WISEA J110524.16+594341.2 in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: WISEA J110524.16+594341.2 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Active galaxies, Astronomical objects discovered in 1990, LEDA objects, so understanding it makes those chapters shorter.
In everyday life: Look for WISEA J110524.16+594341.2 outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
