ILT J2336+1842

ILT J2336+1842 is a astronomy topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand ILT J2336+1842 rather than just read about it. In short: ILT J2336+1842 also known as ILT J233624.72+184247.9 is a high-redshift quasar, and radio galaxy at z = 6.6, equivalent to a distance of 17.55 billion light years (5,380 megaparsecs) away. The galaxy has an apparent Z magnitude of 22.04 and is in the constellation of Pegasus.

ILT J2336+1842 belongs to astronomy; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect ILT J2336+1842 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of ILT J2336+1842 from memory before moving on to harder problems.

Reference excerpt

ILT J2336+1842 also known as ILT J233624.72+184247.9 is a high-redshift quasar, and radio galaxy at z = 6.6, equivalent to a distance of 17.55 billion light years (5,380 megaparsecs) away. The galaxy has an apparent Z magnitude of 22.04 and is in the constellation of Pegasus. The galaxy was first discovered in 2022 in a survey of 24 radio-bright quasars between redshifts z = 4.9 to z = 6.6. As of 2023, it is believed to be the most distant radio galaxy known, greatly succeeding TGSS J1530+1049.

Physical properties ILT J2336+1842 is a dwarf galaxy that is not known to be a part of galaxy clusters and it is probably a field galaxy. Using an angular diameter of 0.1 arcsecs from the eight data release from the DESI telescope, and a redshift-based distance of 5,380 megaparsecs, it has an estimated diameter of 8,500 light years (2,600 parsecs). The galactic center contains a radio-bright quasar with an estimated absolute luminosity of -24.32, equivalent to 457.09 billion L☉ making it one of the most luminous high redshift quasars discovered. In 2023, it was discovered in the second data-release of the LOFAR Two-Metre Sky Survey (LoTSS). The radio lobes have an extent of 54.8 kiloparsecs or 179,000 light years across based on an angular diameter of 10.13 arcsecs. With a predicted redshift of z = 6.6 it is believed to the furthest known radio galaxy being more distant than the previous most distant radio galaxy, TGSS J1530+1049.

Worked examples

Example 1 — a first encounter with ILT J2336+1842

Start with the simplest possible case. Write down what ILT J2336+1842 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 ILT J2336+1842 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 ILT J2336+1842 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 ILT J2336+1842

In research: ILT J2336+1842 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 ILT J2336+1842 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: ILT J2336+1842 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Quasars, Radio galaxies, so understanding it makes those chapters shorter.
In everyday life: Look for ILT J2336+1842 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.
