Reference excerpt

SDSS J094836.34+154813.3 also known as [LHC2018] J147.15141+15.80372, is a radio galaxy located in the constellation of Leo. The redshift of the galaxy has been determined to be (z) 0.334.

Description SDSS J094836.34+154813.3 is an elliptical galaxy residing as the brightest cluster galaxy of the WHL J094836.3+154813 with 22 confirmed galaxy member candidates, but it does not belong to any superclusters. The R-band magnitude of the galaxy is 17.60 magnitude while the absolute magnitude is -23.64. The central nucleus of the galaxy is active and it has been classified as a Fanaroff-Riley Class Type I radio galaxy with its total flux density calculated as 41.70 mJy by NRAO VLA Sky Survey (NVSS). The radio morphology is mainly elongated, depicted as a single elliptical profile component. There is a presence of a radio core with a core flux density of 37.69 mJy while the total radio emission flux is 42.70 mJy. The total radio power has been calculated to be 16.31 × 1024 WHz−1. A study found the total stellar mass of the galaxy is 11.32 M☉. The log radio luminosity is 25.17 W Hz−1 while the radio flux density at 1.4 GHz frequencies is 41.7 mJy. The rest-frame r0.1 magnitude is -22.963. Evidence found the galaxy is powered by its own active galactic nucleus (AGN).

Worked examples

Example 1 — a first encounter with SDSS J094836.34+154813.3

Start with the simplest possible case. Write down what SDSS J094836.34+154813.3 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 SDSS J094836.34+154813.3 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 SDSS J094836.34+154813.3 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 SDSS J094836.34+154813.3

In research: SDSS J094836.34+154813.3 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 SDSS J094836.34+154813.3 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: SDSS J094836.34+154813.3 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 J094836.34+154813.3 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.
