J1328+2752

J1328+2752 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 J1328+2752 rather than just read about it. In short: J1328+2752 is a Type 2 Seyfert galaxy located in the constellation of Canes Venatici. The redshift of the galaxy is (z) 0.091 and it was first discovered from a sample of 167 dual active galactic nuclei by astronomers in January 2010.

Key takeaways

J1328+2752 belongs to astronomy; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect J1328+2752 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of J1328+2752 from memory before moving on to harder problems.

Reference excerpt

J1328+2752 is a Type 2 Seyfert galaxy located in the constellation of Canes Venatici. The redshift of the galaxy is (z) 0.091 and it was first discovered from a sample of 167 dual active galactic nuclei by astronomers in January 2010. It has been categorized as a double-double radio galaxy.

Description J1328+2752 is a radio galaxy. The radio structure of the galaxy is classified as compact, with a visible flat radio spectrum core in the center that is shown to have weak radio emission based on a 607 MHz image. The outer radio lobes have an asymmetric appearance. There is a hotspot feature present in the southern radio lobe while the northern radio lobe shows an absence of a hotspot feature. The northern outer radio lobe has been described to have a sharp bending angle towards the northeast direction. The inner double lobes are also asymmetric but embedded within an area of older radio emission. A bright hotspot is shown dominating over the northern component on the inner side. Both inner and outer lobes have spectral indexes of 0.64 ± 0.002 and 0.56 ± 0.06 respectively. The host galaxy of J1328+2752 is an elliptical galaxy with emission lines that are described as highly ionized with a narrow appearance. The host galaxy also contains a disk component that dominates an area over 2.5 kiloparsecs with a bulge dominated inner portion. A study published in 2021 has confirmed J1328+2752 has a binary supermassive black hole with an estimated separation of only six parsecs based on existence of two radio core components from imaging made by Very Long Baseline Array (VLBA) and its double-peaked emission lines with the same separation gap as the components. A study published in 2024, has found the presence of a single central component with an unresolved appearance at all frequencies and the flux density increasing by around a factor of 3.

Worked examples

Example 1 — a first encounter with J1328+2752

Start with the simplest possible case. Write down what J1328+2752 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 J1328+2752 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 J1328+2752 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 J1328+2752

In research: J1328+2752 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 J1328+2752 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: J1328+2752 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Active galaxies, Astronomical objects discovered in 2010, Canes Venatici, so understanding it makes those chapters shorter.
In everyday life: Look for J1328+2752 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.
