Reference excerpt

WISEA J131142.45+563236.6 also known as RGZ J131142.4+563236, is a radio galaxy located in the constellation of Ursa Major. The redshift of the galaxy is estimated to be (z) 0.248 and it was first discovered in the Sixth Cambridge Survey of Radio Sources by astronomers in September 1990.

Description WISEA J131142.45+563236.6 is a red luminous galaxy residing as the brightest cluster galaxy of the WHL J131142.5+563236 galaxy cluster with 20 confirmed galaxy member candidates. The R-band magnitude of the galaxy is 17.85 while the R-band absolute magnitude of the galaxy is -22.69. The nucleus is active and it has been classified as a wide angle-tail Fanaroff-Riley Class Type II radio galaxy. The radio jets are detected with the jets having an opening angle of 168.7° and curvature radius of 556.9 arcseconds. The largest known angular size of the source is 48 arcseconds while the largest linear size is 193.0 kiloparsecs. The spectral index of the source is 1.11α between 1.4 and 3 GHz frequencies. The radio power has been calculated to be 4.56 × 1024 WHz-1. A study found there are presence of two radio lobes. When observed, the lobes are found to have measured projected lengths of 72.1 and 102.5 kiloparsecs. The angular separation of the lobes are calculated to be 11.7 and 16.7 arcseconds from each other respectively. The total radio luminosity is 4.6 × 1024 W Hz-1 while the total radio flux density calculated by NRAO VLA Sky Survey (NVSS) is 24.3 mJy. The source is also bent with the bending angle measured to be 3.6° while the excess bending angle is -6.7°. Evidence found the R-band luminosity of the galaxy is 4.81 × 1010 Lʘ.

Worked examples

Example 1 — a first encounter with WISEA J131142.45+563236.6

Start with the simplest possible case. Write down what WISEA J131142.45+563236.6 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 J131142.45+563236.6 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 J131142.45+563236.6 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 J131142.45+563236.6

In research: WISEA J131142.45+563236.6 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 J131142.45+563236.6 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 J131142.45+563236.6 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Active galaxies, LEDA objects, Radio galaxies, so understanding it makes those chapters shorter.
In everyday life: Look for WISEA J131142.45+563236.6 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.
