PGC 1470080

PGC 1470080 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 PGC 1470080 rather than just read about it. In short: PGC 1470080 is a type E elliptical galaxy located in the Boötes constellation. It is located 3 billion light-years away from the Solar System and has a diameter of 571,000 light-years, making it a type-cD galaxy and one of the largest.

Reference excerpt

PGC 1470080 is a type E elliptical galaxy located in the Boötes constellation. It is located 3 billion light-years away from the Solar System and has a diameter of 571,000 light-years, making it a type-cD galaxy and one of the largest.

Characteristics It is the brightest cluster galaxy of the galaxy cluster, WHL J143845.0+145412. The galaxy acts as a gravitational lens for a much more distant spiral galaxy which is called SGAS J143845+145407. This creates a mirror image of the galaxy thus creating a masterpiece. Such of this phenomenon occurs, when a massive celestial body such as a galaxy cluster which creates sufficient curvature of spacetime for the path of light to be bent by the lens. This creates multiple images of the original galaxy which as seen, the background object appears as a distorted arc or a ring. This observation takes advantage of gravitational lensing to peer through early universe galaxies. It helps to reveal details of distant galaxies that is unobtainable and allowing astronomers to determine star formation in such early galaxies. Not to mention, it gives scientists a better insight on how evolution of galaxies have unfolded. By using gravitational lensing is also a very useful tool which contributes significant new results in areas as different as the cosmological distance scale, dark matter in halos and galaxy structures. According to the Hubble image of PGC 1470080, it is shown to be a peculiar lenticular galaxy rather than an elliptical galaxy as expected.

Worked examples

Example 1 — a first encounter with PGC 1470080

Start with the simplest possible case. Write down what PGC 1470080 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 PGC 1470080 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 PGC 1470080 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 PGC 1470080

In research: PGC 1470080 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 PGC 1470080 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: PGC 1470080 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Boötes, Elliptical galaxies, LEDA objects, so understanding it makes those chapters shorter.
In everyday life: Look for PGC 1470080 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.
