J1017+6352

J1017+6352 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 J1017+6352 rather than just read about it. In short: J1017+6352, also known as J101801.6+635228 and NYU-VAGC 0205375, is a radio galaxy located in the constellation of Ursa Major. The redshift of the galaxy is (z) 0.233 and it was first discovered in the Sixth Cambridge Survey of Radio Sources by astronomers in February 1990.

Key takeaways

J1017+6352 belongs to astronomy; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect J1017+6352 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of J1017+6352 from memory before moving on to harder problems.

Reference excerpt

J1017+6352, also known as J101801.6+635228 and NYU-VAGC 0205375, is a radio galaxy located in the constellation of Ursa Major. The redshift of the galaxy is (z) 0.233 and it was first discovered in the Sixth Cambridge Survey of Radio Sources by astronomers in February 1990.

Description J1017+6352 is a red luminous galaxy, residing as the brightest cluster galaxy (BCG) of the galaxy cluster, GMBCG J154.50781+63.87501. It is also classified as an elliptical galaxy with an r-band absolute magnitude of -23.73. The stellar velocity dispersion of the galaxy is estimated to be 261 kilometers per second and the galaxy's effective radius is 18.4 kiloparsecs. The physical size of the galaxy is 160 kiloparsecs. The g–r color value is 1.42 magnitude. The nucleus is active and it is classified as a narrow-angle tail Fanaroff-Riley Class Type II radio galaxy. The galaxy contains a radio source with a radio power of 36.01 × 1024 W Hz-1. The total flux density of the source at 1400 MHz frequencies is estimated to be 222 mJy, while at 150 MHz the flux density is 1349 mJy. The spectral index of the source is -0.81α between 1400 and 150 MHz. It is also a C-shaped radio galaxy, with the extent of the source being only 0.09 megaparsecs in total, making the source small. The total radio luminosity at 1.4 GHz is 25.56 W Hz-1. A study published in 2025, reclassified it as a bent wide-angle tail (WAT) Fanaroff-Riley Class Type I radio galaxy characterized by its bent radio lobes. There is a radio jet with an opening angle of 105.7°, and the curvature of the jet is 18.2 arcseconds. The largest known angular size of the galaxy is 56 arcseconds, and the largest known linear size is 215 kiloparsecs.

Worked examples

Example 1 — a first encounter with J1017+6352

Start with the simplest possible case. Write down what J1017+6352 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 J1017+6352 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 J1017+6352 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 J1017+6352

In research: J1017+6352 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 J1017+6352 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: J1017+6352 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Active galaxies, Astronomical objects discovered in 1990, Elliptical galaxies, so understanding it makes those chapters shorter.
In everyday life: Look for J1017+6352 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.
