Reference excerpt

WISEA J095351.39+221531.7 also known as NYU-VAGC 2251145 and J095351.36+221532.1, is a radio galaxy located in the constellation of Leo. The redshift of the galaxy is estimated to be (z) 0.264.

Description WISEA J095351.39+221531.7 is a red luminous galaxy residing as the brightest cluster galaxy (BCG) of the galaxy cluster, GMBCG J148.46405+22.25892. The total absolute magnitude of the galaxy is estimated to be -23.20 magnitude while the g–r color value is 1.54 magnitude. A stellar mass of 11.29 h−2 M☉ has been calculated for the galaxy. The nucleus is active and it has been categorized as a wide angle-tail (WAT) Fanaroff-Riley Class Type II radio galaxy. The total logarithmic luminosity is 25.27 W Hz−1 at 1.4 GHz frequencies and the radio spectral index is 0.61α between 3 and 1.4 GHz. A radio jet is resolved, with a jet opening angle of 145.5° and a jet curvature radius of 38.0 arcseconds. The largest angular size of the source is 45 arcseconds. A study published in 2015 showed radio lobes are resolved ,with a total lobe flux density of 0.063 mJy and the radio core has a measured core flux density of 0.0187 mJy. The lobes are separated from each other by just 0.007526°. The total radio flux density for the source at 1.4 GHz is 87.9 mJy and the total radio luminosity is 25.26 W Hz−1. It is a class b radio galaxy, categorized as an early-type galaxy, with its stellar velocity dispersion calculated to be 292 kilometers per seconds and its effective radius is 12.8 kiloparsecs. The total physical size of the galaxy is 171 kiloparsecs. The total radio power at 1.4 GHz is 25.26 W Hz−1.

Worked examples

Example 1 — a first encounter with WISEA J095351.39+221531.7

Start with the simplest possible case. Write down what WISEA J095351.39+221531.7 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 J095351.39+221531.7 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 J095351.39+221531.7 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 J095351.39+221531.7

In research: WISEA J095351.39+221531.7 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 J095351.39+221531.7 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 J095351.39+221531.7 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Active galaxies, Elliptical galaxies, LEDA objects, so understanding it makes those chapters shorter.
In everyday life: Look for WISEA J095351.39+221531.7 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.
