Reference excerpt

WISEA J160318.98+031644.8 also known as OGC 1012, is a radio galaxy located in the constellation of Serpens. The redshift of the galaxy is (z) 0.222 and it was first discovered in a sample of 2,712 radio-loud active galactic nuclei obtained by the Sloan Digital Sky Survey (SDSS) in September 2005.

Description WISEA J160318.98+031644.8 is a giant elliptical galaxy of type E morphology. It is also a luminous red galaxy found to reside in the center as the brightest cluster galaxy (BCG) of the galaxy cluster, WHL J160319.0+031645 with at least 114 confirmed member candidates. The estimated J-band and H-band infrared color magnitudes of the galaxy is 15.84 and 15.00 magnitudes respectively. The absolute magnitude of the galaxy is -23.42 and it has a total stellar mass of 11.34 M☉. The nucleus is active and has been categorized as a Fanaroff-Riley Class Type II radio galaxy. The radio flux density calculated by the NRAO VLA Sky Survey (NVSS) at 1.4 GHz frequencies is 127.00 mJy. The radio luminosity is 25.26 W Hz−1. A study published in 2022, found it is a bent-tailed radio galaxy which can be further classified as a wide-angle tail radio galaxy. The total flux density estimated at 1.4 GHz is 132.94 mJy, while the flux density at 3 GHz is 66.86 mJy. The spectral index between 1.4 and 3 GHz is 0.9α. A radio jet has been detected, with a jet opening angle of 132.8° and a jet curvature radius of 30.8 arcseconds. The radio lobes are resolved, with a flux density of 0.128 Jy and have lobe to lobe separation by 0.002° while the radio core remains undetected. The largest angular size of the galaxy is 34 arcseconds and the largest linear size is 126.0 kiloparsecs. Evidence also found the source is a double, with an approximate bending angle of 41.3°. The excess bending angle is 34.4°.

Worked examples

Example 1 — a first encounter with WISEA J160318.98+031644.8

Start with the simplest possible case. Write down what WISEA J160318.98+031644.8 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 J160318.98+031644.8 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 J160318.98+031644.8 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 J160318.98+031644.8

In research: WISEA J160318.98+031644.8 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 J160318.98+031644.8 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 J160318.98+031644.8 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Active galaxies, Astronomical objects discovered in 2005, Elliptical galaxies, so understanding it makes those chapters shorter.
In everyday life: Look for WISEA J160318.98+031644.8 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.
