Reference excerpt

WISEA J085845.08+171002.6 also known as [SBP2022] J0858+1710 and J085845.10+171003.1, is a radio galaxy located in the constellation of Cancer. The redshift of the galaxy is estimated to be (z) 0.330.

Description WISEA J085845.08+171002.6 is a red luminous galaxy residing as the brightest cluster galaxy of the WHL J085845.1+171003 galaxy cluster with 15 confirmed galaxy members. The R-band magnitude of the galaxy has been estimated to be 17.81 magnitude. The nucleus is active and it is either a bent-tailed or a wide angle-tail Fanaroff-Riley Class Type II radio galaxy characterized by its radio lobes displaying an opening angle that exceeds 90° and has a radio flux density of 59.10 mJy that is calculated by NRAO VLA Sky Survey (NVSS). The total radio power of the source is 24.71 × 1024 WHz−1. There is a radio jet with the jet opening angle estimated to be 97.5° and the jet curvature radius is measured to be 14.4 arcseconds in total. The largest angular size of the source is 43 arcseconds while the largest known linear size is 211 kiloparsecs. The radio spectral index is 0.69α between 3 GHz and 4 GHz frequencies while the 3 GHz flux density is 40.15 mJy. The g–r color value of the galaxy is 1.71 magnitude. A study published in 2015, found it is a C-shaped radio galaxy located in a moderately galaxy environment with a total radio luminosity of 25.38 W Hz-1 with the total extent of the source being 0.15 megaparsecs making it a small. The absolute magnitude of the galaxy has been calculated to be -23.66. The total stellar mass of the galaxy has been estimated as 11.48 M☉ with the radio luminosity at 1.4 GHz being 25.30 W Hz−1. The rest-frame r0.1 magnitude is -23.12.

Worked examples

Example 1 — a first encounter with WISEA J085845.08+171002.6

Start with the simplest possible case. Write down what WISEA J085845.08+171002.6 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 J085845.08+171002.6 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 J085845.08+171002.6 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 J085845.08+171002.6

In research: WISEA J085845.08+171002.6 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 J085845.08+171002.6 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 J085845.08+171002.6 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Active galaxies, Cancer (constellation), LEDA objects, so understanding it makes those chapters shorter.
In everyday life: Look for WISEA J085845.08+171002.6 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.
