TXS 1159+583

TXS 1159+583 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 TXS 1159+583 rather than just read about it. In short: TXS 1159+583 is a radio galaxy located in the constellation of Ursa Major. The redshift of the galaxy is (z) 0.102 and it was first discovered by astronomers as an astronomical radio source in September 1973, where it was identified as 4C 58.23 based on its radio and optical position.

Key takeaways

TXS 1159+583 belongs to astronomy; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect TXS 1159+583 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of TXS 1159+583 from memory before moving on to harder problems.

Reference excerpt

TXS 1159+583 is a radio galaxy located in the constellation of Ursa Major. The redshift of the galaxy is (z) 0.102 and it was first discovered by astronomers as an astronomical radio source in September 1973, where it was identified as 4C 58.23 based on its radio and optical position. It is the brightest cluster galaxy (BCG) of Abell 1446.

Description TXS 1159+583 is classified as a head-tail radio galaxy or a wide angle-tailed (WAT) radio galaxy, with its tail structure remarkably extendible away from the galaxy host. The host galaxy is a large elliptical galaxy, dominating the center of the galaxy cluster and has been depicted to have a much more brighter appearance when compared to other galaxies members. There is a double nucleus present. The source of the galaxy is considered as compact and it has been classified as a bend-double. When observed with both NRAO and Very Large Array (VLA), it is found to contain a compact nuclear component that contains a steep radio spectrum. There is also a hotspot feature found as clearly resolved and also bright, with an extend of around eight arcseconds. A radio jet is seen emerging outwards from the hotspot region before disappearing into the tail region. Further observations made by the VLA, would find the source is also small and also asymmetric given that the southern tail is both longer and much more narrower when compared to the tail in the north. The tail lobe of the southern one is found to have little signs of polarization between 5% and 15% but increases up to 40% upon reaching a second broadening. Two radio lobes have also been discovered in the galaxy, bending into a C-shape. Traces of radio emission are shown to be coinciding together with the cluster X-ray emission within a 47 kiloparsec radius, hinting the galaxy has sunk to the bottom of the gravitational well. The radio lobes are also found also asymmetrical with the southern lobe being around 105 kiloparsecs long and the northern lobe only around 45 kiloparsecs in length.

Worked examples

Example 1 — a first encounter with TXS 1159+583

Start with the simplest possible case. Write down what TXS 1159+583 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 TXS 1159+583 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 TXS 1159+583 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 TXS 1159+583

In research: TXS 1159+583 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 TXS 1159+583 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: TXS 1159+583 is common in secondary-school and first-year university syllabi. It links to neighbouring topics 4C objects, Active galaxies, Astronomical objects discovered in 1973, so understanding it makes those chapters shorter.
In everyday life: Look for TXS 1159+583 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.
