Reference excerpt

WISEA J085101.70+163857.3 also known as [YHW2016] J132.75719+16.64924 and J085101.56+163848.6, is a radio galaxy located in the constellation of Cancer. The redshift of the galaxy is estimated to be located at (z) 0.332.

Description WISEA J085101.70+163857.3 is an elliptical galaxy in stages of a gravitational interaction with another galaxy. It is also the brightest cluster galaxy of the WHL J085101.7+163857 galaxy cluster with 14 confirmed galaxy member candidates but it does not belong to any superclusters. The R-band magnitude of the galaxy has been estimated to be 18.04 while its absolute magnitude is -23.32. The nucleus is found to be active and it has been categorized as a non-bend Fanaroff-Riley Class Type I/II radio galaxy with the total flux density calculated to be 18.70 mJy at 1.4 GHz frequencies by NRAO VLA Sky Survey (NVSS). The radio morphology is found to be hybrid with one radio lobe being classified of FR I type whereas the other lobe is of FR II type although evidence confirms it has both characteristics of Fanaroff-Riley Class Type I and Type II radio galaxies, with presence of linear structures located near the radio core and edges of the structure. The radio core itself, has a measured core flux density of 7.45 mJy while the radio emission has a flux density of 31.00 mJy. The total radio power has been calculated to be 11.58 × 1024 WHz-1. A study found it is a wide-angle-tailed radio galaxy (WAT). The flux density at 3 MHz is 14.94 mJy whereas the spectral index between 1.4 and 3 GHz is 1.06α. There is also a presence of a radio jet with the opening angle estimated to be 164.4° while the jet curvature radius is 148.3 arcseconds. The largest angular size of the source is 99 arcseconds whereas the largest linear size is 489 kiloparsecs. A logarithmic radio luminosity of 25.12 W Hz-1 at 1.4 GHz has been calculated for the source.

Worked examples

Example 1 — a first encounter with WISEA J085101.70+163857.3

Start with the simplest possible case. Write down what WISEA J085101.70+163857.3 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 J085101.70+163857.3 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 J085101.70+163857.3 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 J085101.70+163857.3

In research: WISEA J085101.70+163857.3 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 J085101.70+163857.3 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 J085101.70+163857.3 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Active galaxies, Cancer (constellation), Elliptical galaxies, so understanding it makes those chapters shorter.
In everyday life: Look for WISEA J085101.70+163857.3 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.
