SN 2004gt

SN 2004gt 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 SN 2004gt rather than just read about it. In short: SN 2004GT was a Type Ic supernova that happened in the interacting galaxy NGC 4038 on December 12, 2004. The event occurred in a region of condensed matter in the western spiral arm.

Key takeaways

SN 2004gt belongs to astronomy; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect SN 2004gt to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of SN 2004gt from memory before moving on to harder problems.

Reference excerpt

SN 2004GT was a Type Ic supernova that happened in the interacting galaxy NGC 4038 on December 12, 2004. The event occurred in a region of condensed matter in the western spiral arm. The progenitor was not identified from older images of the galaxy, and is either a type WC Wolf-Rayet star with a mass over 40 times that of the Sun, or a star 20 to 40 times as massive as the Sun in a binary star system.

Worked examples

Example 1 — a first encounter with SN 2004gt

Start with the simplest possible case. Write down what SN 2004gt 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 SN 2004gt 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 SN 2004gt 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 SN 2004gt

In research: SN 2004gt 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 SN 2004gt 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: SN 2004gt is common in secondary-school and first-year university syllabi. It links to neighbouring topics Astronomical objects discovered in 2004, Corvus (constellation), Type Ib and Ic supernovae, so understanding it makes those chapters shorter.
In everyday life: Look for SN 2004gt 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.
