J094700.09+254045.8

J094700.09+254045.8 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 J094700.09+254045.8 rather than just read about it. In short: J094700.09+254045.8 also known as OGC 543 and SDSS J094700.08+254045.7 is a massive barred spiral galaxy located in the constellation of Leo. The redshift of the galaxy is (z) 0.109 and it is found to belong to a class of super spirals; i.e. a rare type of spiral galaxies that are more larger and distant as compared to the Milky Way.

Key takeaways

J094700.09+254045.8 belongs to astronomy; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect J094700.09+254045.8 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of J094700.09+254045.8 from memory before moving on to harder problems.

Reference excerpt

J094700.09+254045.8 also known as OGC 543 and SDSS J094700.08+254045.7 is a massive barred spiral galaxy located in the constellation of Leo. The redshift of the galaxy is (z) 0.109 and it is found to belong to a class of super spirals; i.e. a rare type of spiral galaxies that are more larger and distant as compared to the Milky Way.

Description J094700.09+254045.8 is classified as a grand-design spiral galaxy with defined spiral arms based on a deep convolutional neural network model that is used by astronomers in October 2022. It has a bulge fraction ratio calculated as B/T = 0.21. The galactic disk is found to have a disk inclination of 43° at a position angle of 150° and a measured disk exponential scale of 17.31. Evidence found J094700.09+254045.8 is a Seyfert type 1 galaxy, hosting an active galactic nucleus (AGN). The inner regions of the nucleus are described to have bluer u – r colors compared to its inner disk, with further evidence of the u – r colors progressively being more bluer as the disk radius increases. The stellar population of the galaxy is found mainly dominated by both old population of stars and also a young star population based on ultraviolet and near-infrared data points. Most of the near-infrared emission appears mainly dominated by both polycyclic aromatic hydrocarbons (PAHs) and warm interstellar dust produced through star formation. The total stellar mass is estimated to be 1.8+0.3−0.2 × 1011 M☉ while the total star formation is estimated to be 13.5 ± 0.2 M☉ per year based on the luminosity calculated by Wide-field Infrared Survey Explorer (WISE). A spectral energy distribution (SED) fit calculated the dust mass as 108 M☉. A study published in 2025, has found the galaxy has presence of molecular gas.

Worked examples

Example 1 — a first encounter with J094700.09+254045.8

Start with the simplest possible case. Write down what J094700.09+254045.8 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 J094700.09+254045.8 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 J094700.09+254045.8 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 J094700.09+254045.8

In research: J094700.09+254045.8 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 J094700.09+254045.8 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: J094700.09+254045.8 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Active galaxies, Barred spiral galaxies, LEDA objects, so understanding it makes those chapters shorter.
In everyday life: Look for J094700.09+254045.8 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.
