Reference excerpt

WISEA J122413.39+160600.8 also known as NYU-VAGC 1771198, is a radio galaxy located in the constellation of Coma Berenices. The redshift of the galaxy is estimated to be at (z) 0.233.

Description WISEA J122413.39+160600.8 is an elliptical galaxy residing as the brightest cluster galaxy of the WHL J122413.4+160601 galaxy cluster with nine confirmed galaxy member candidates. The R-band magnitude of the galaxy is 16.76 whereas its absolute magnitude is -23.32. The stellar velocity dispersion of the galaxy is 310 kilometers per seconds and it has a galaxy effective radius of 10.7 kiloparsecs. The total physical size is 346 kiloparsecs. The galaxy shows a presence of a central active galaxy nucleus and is categorized as a Fanaroff-Riley Class Type II radio galaxy with a total flux density of 87.00 mJy measured by NRAO VLA Sky Survey at 1.4 GHz frequencies. Radio imaging made with Faint Images of the Radio Sky at Twenty-Centimeters (FIRST) found it is a hybrid radio galaxy with the first radio lobe displaying a FR-I morphology while the other lobe has a FR-II morphology. The radio core is detected and it has a core flux density of 4.23 mJy. The luminosity distance of the source is 1177.9 megaparsecs. The total radio power at 1.4 GHz is estimated to be 25.17 W Hz-1. A study in 2025 described it as a narrow-angle-tail (NAT) radio galaxy. The radio jets are resolved with the opening angle estimated to be 36.8° whereas the jet curvature radius is 12.3 arcseconds. The spectral index is found to be 0.94α between 1.4 and 3 GHz frequencies. The largest angular size of the source is 85 arcseconds while the largest linear size is 327.0 kiloparsecs. The g–r color value of the galaxy is 1.48 magnitude.

Worked examples

Example 1 — a first encounter with WISEA J122413.39+160600.8

Start with the simplest possible case. Write down what WISEA J122413.39+160600.8 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 J122413.39+160600.8 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 J122413.39+160600.8 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 J122413.39+160600.8

In research: WISEA J122413.39+160600.8 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 J122413.39+160600.8 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 J122413.39+160600.8 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Active galaxies, Coma Berenices, Elliptical galaxies, so understanding it makes those chapters shorter.
In everyday life: Look for WISEA J122413.39+160600.8 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.
