Reference excerpt

SDSS J110347.36+055047.5 also known as [LHC2018] J165.94736+05.84654, is a radio galaxy located in the constellation of Leo. The redshift of the galaxy is estimated to be located at (z) 0.244.

Description SDSS J110347.36+055047.5 is an elliptical galaxy of Type E morphology, residing as the brightest cluster galaxy of the WHL J110347.4+055048 galaxy cluster belonging as part of a supercluster with 25 confirmed galaxy member candidates. The R-band magnitude of the galaxy has been found to be 16.98 while its absolute magnitude is calculated to be -23.42. The central nucleus is found to be active and it has been categorized as a non-bend compact radio galaxy or a low-excitation radio galaxy (LERG) with its total flux density estimated as 6.60 mJy by NRAO VLA Sky Survey (NVSS). The radio morphology is mainly elongated, depicted as a single elliptical profile component although radio contour imaging made by Faint Images of the Radio Sky at Twenty-Centimeters (FIRST) suggested the radio morphology is compact and described by a single point-like component. There is also a presence of a radio core with its total core flux density of 2.04 mJy while the total radio emission flux density is 4.70 mJy. The luminosity distance of the source is 1239.6 megaparsecs. Radio imaging by NVSS also showed there is a single component with a total integrated radio flux density of 4.70 mJy. The G-band magnitude of the galaxy is 18.14 while the I-band magnitude is 16.52. A study found the total stellar mass of the galaxy is 11.33 M☉. The log radio luminosity is 23.91 W Hz-1 while the radio flux density at 1.4 GHz is 4.7 mJy. The rest-frame r0.1 magnitude is -22.685. Evidence found the galaxy is powered by its active galactic nucleus.

Worked examples

Example 1 — a first encounter with SDSS J110347.36+055047.5

Start with the simplest possible case. Write down what SDSS J110347.36+055047.5 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 SDSS J110347.36+055047.5 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 SDSS J110347.36+055047.5 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 SDSS J110347.36+055047.5

In research: SDSS J110347.36+055047.5 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 SDSS J110347.36+055047.5 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: SDSS J110347.36+055047.5 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 SDSS J110347.36+055047.5 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.
