UGC 4653

UGC 4653 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 UGC 4653 rather than just read about it. In short: UGC 4653 known as Arp 195, is a trio of interacting galaxies located 763 million light-years away from the Solar System in the Lynx constellation. The galaxies are being distorted through gravitational interactions with each other.

Key takeaways

UGC 4653 belongs to astronomy; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect UGC 4653 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of UGC 4653 from memory before moving on to harder problems.

Reference excerpt

UGC 4653 known as Arp 195, is a trio of interacting galaxies located 763 million light-years away from the Solar System in the Lynx constellation. The galaxies are being distorted through gravitational interactions with each other. The first known reference for this object, was in 1959 where B.A. Vorontsov-Vel'yaminov compiled it inside the Vorontsov-Vel'yaminov Interacting galaxies, as VV 243. This image of UGC 4653 was captured by the Hubble Space Telescope. The galaxies make up the 195th object in the Atlas of Peculiar Galaxies created by Halton Arp. They fall into the category of galaxies with material ejected from nuclei. UGC 4653 has active nuclear regions which produce infrared (IR) emissions. These appear to be more like AGNs than HII regions. A study published in 2023, confirmed all three galaxies of the UGC 4653 system are spirals. The southern galaxy is a face-on galaxy hosting a bright core, while the central is edge-on but no clear distinction whether it is an early or late-type galaxy. The northern galaxy has a tidal tail and is of late-type morphology. With the exception of the third, both galaxies contain presence of strong emission lines.

Supernova Type Ia supernova, SN 2008bv was discovered in UGC 4653 with a magnitude of 18.3. It was located 1".7 east and 3".9 south of the nucleus.

Worked examples

Example 1 — a first encounter with UGC 4653

Start with the simplest possible case. Write down what UGC 4653 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 UGC 4653 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 UGC 4653 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 UGC 4653

In research: UGC 4653 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 UGC 4653 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: UGC 4653 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Arp objects, Interacting galaxies, LEDA objects, so understanding it makes those chapters shorter.
In everyday life: Look for UGC 4653 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.
