Reference excerpt

RGZ J145001.5+144747 also known as J145001.6+144748, is a radio galaxy located in the constellation of Boötes. The redshift of the galaxy is (z) 0.299 and it is the brightest cluster galaxy (BCG) of the galaxy cluster, GMBCG J222.50624+14.79665.

Description RGZ J145001.5+144747 is categorized as a luminous red supergiant elliptical galaxy with a z-band absolute magnitude of -23.04. The supermassive black hole located at the center of the galaxy is 8.65 M☉ while the g–r color values of the galaxy is 1.59 magnitude. The nucleus is active and is a Fanaroff-Riley Class type I radio galaxy. There are two resolved radio lobes present in the east and west, with measured lobe lengths of 87 and 80 kiloparsecs. The flux density at 1.4 GHz calculated by Faint Images of the Radio Sky at Twenty-Centimeters (FIRST) for both lobes are estimated to be 29.9 and 34.1 mJy respectively at flux density cuts of 3σ. The radio source is a double and has an approximate measured bending angle of 0.8°. The source also has a C-shaped morphology with a total extent of 0.15 megaparsecs and a total radio luminosity of 25.39 W Hz−1, suggesting the galaxy is located in a rich galaxy environment. A study published in 2025, found it is a bent-tail radio galaxy (BTRG), which can be further classified as a wide-angle tail (WAT) radio galaxy. The total flux density at 3 GHz frequencies is estimated to be 47.54 mJy. The opening angle of the source is 143.4°, with the curvature of its radio jets estimated as 55.3 arcseconds. The largest linear size of the source is 285 kiloparsecs.

Illustrations

Worked examples

Example 1 — a first encounter with RGZ J145001.5+144747

Start with the simplest possible case. Write down what RGZ J145001.5+144747 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 RGZ J145001.5+144747 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 RGZ J145001.5+144747 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 RGZ J145001.5+144747

In research: RGZ J145001.5+144747 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 RGZ J145001.5+144747 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: RGZ J145001.5+144747 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Active galaxies, Boötes, Elliptical galaxies, so understanding it makes those chapters shorter.
In everyday life: Look for RGZ J145001.5+144747 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.
