MRC 0051–097

MRC 0051–097 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 MRC 0051–097 rather than just read about it. In short: MRC 0051–097 also known as OGC 666 and NYU-VAGC 0306384, is a radio galaxy located in the constellation of Cetus. The redshift of the galaxy is (z) 0.269 and it was first discovered by astronomers with the Molongo Radio Telescope in February 1981.

Key takeaways

MRC 0051–097 belongs to astronomy; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect MRC 0051–097 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of MRC 0051–097 from memory before moving on to harder problems.

Reference excerpt

MRC 0051–097 also known as OGC 666 and NYU-VAGC 0306384, is a radio galaxy located in the constellation of Cetus. The redshift of the galaxy is (z) 0.269 and it was first discovered by astronomers with the Molongo Radio Telescope in February 1981.

Description MRC 0051–097 is an elliptical galaxy residing as the brightest cluster galaxy of the WHL J005354.2–092823 galaxy cluster with 47 confirmed galaxy member candidates. The R-band magnitude of the galaxy is 17.03. The stellar velocity dispersion is 308 kilometers per seconds while the galaxy effective radius is 15.7 kiloparsecs. The absolute magnitude has been estimated as -23.62 whereas the physical size is 347 kiloparsecs. The radio source of the galaxy is found mainly compact on sub-arcsecond scales with its total flux density estimated to be 0.337 mJy at 1400 MHz frequencies by NRAO VLA Sky Survey (NVSS) with a calculated solar elongation of 34.9°. The spectral index of the source is -0.83α while the scintillation index is less than 0.02. A study has found the source is a double with a 162 MHz flux density of 1.634 mJy with a normalized scintillation index of 18.9. Radio imaging by Faint Images of the Radio Sky at Twenty-Centimeters (FIRST) detected four separate components associated with the source. Evidence found the galaxy is found powered by its active galactic nucleus (AGN) with its total log radio luminosity estimated to be 25.86 W Hz−1 and has a 1.4 GHz flux density of 337.4 mJy. The stellar mass of the galaxy is 11.39 M☉. The K-band magnitude of the galaxy is 12.681 based on its isothopal K magnitude calculated by the 2MASS survey.

Worked examples

Example 1 — a first encounter with MRC 0051–097

Start with the simplest possible case. Write down what MRC 0051–097 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 MRC 0051–097 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 MRC 0051–097 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 MRC 0051–097

In research: MRC 0051–097 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 MRC 0051–097 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: MRC 0051–097 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Active galaxies, Astronomical objects discovered in 1981, Cetus (constellation), so understanding it makes those chapters shorter.
In everyday life: Look for MRC 0051–097 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.
