NGC 6264

NGC 6264 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 NGC 6264 rather than just read about it. In short: NGC 6264 is an active Seyfert galaxy located in the constellation of Hercules. The redshift of the galaxy is (z) 0.033 and it was first discovered in June 1864 by the German astronomer Albert Marth who described it as having a magnitude of 15 and is faint, small and also round.

Key takeaways

NGC 6264 belongs to astronomy; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect NGC 6264 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of NGC 6264 from memory before moving on to harder problems.

Reference excerpt

NGC 6264 is an active Seyfert galaxy located in the constellation of Hercules. The redshift of the galaxy is (z) 0.033 and it was first discovered in June 1864 by the German astronomer Albert Marth who described it as having a magnitude of 15 and is faint, small and also round. This galaxy is known to host a triple peaked water megamaser.

Description NGC 6264 is categorized as a barred spiral galaxy of Type Sb or Type Sc+. The nucleus of this galaxy is known to be active and is classified as a Type 2 Seyfert galaxy. The galaxy contains signatures of water maser emission with its own circumnuclear disk warped slightly and also having a thin appearance. The position angle of the disk is -85° and the inclination angle is 90°. The disk's inner and outer radius are 0.18 and 0.77 parsecs respectively. The estimated mass of the Keplerian disk is 0.42 ± 0.03 × 107 M☉. A study has found the supermassive black hole lying in the center of NGC 6264 has a mass of 3.09 ± 0.42 × 107 M☉. The maser features have different acceleration ranges, with the masers in one of the clump features having velocities higher than at least 7 kilometers per second per year. In another clump, the masers have an acceleration of 3.96 ± 1.77 kilometers per second per year. The total star formation of the galaxy is estimated to be around 1.4 M☉ per year. Further evidence also suggests the active galactic nucleus (AGN) is Compton thick. The bolometric luminosity of the AGN is 45.55 erg s−1.

Worked examples

Example 1 — a first encounter with NGC 6264

Start with the simplest possible case. Write down what NGC 6264 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 NGC 6264 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 NGC 6264 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 NGC 6264

In research: NGC 6264 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 NGC 6264 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: NGC 6264 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Active galaxies, Astronomical objects discovered in 1864, Barred spiral galaxies, so understanding it makes those chapters shorter.
In everyday life: Look for NGC 6264 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.
