J080107.90+435030.6

J080107.90+435030.6 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 J080107.90+435030.6 rather than just read about it. In short: J080107.90+435030.6 also known as 6C B075738+435851, is a radio galaxy in the constellation of Lynx. The redshift of the galaxy is (z) 0.255 and it was first discovered from a sample of 2,712 radio-loud active galactic nuclei in the Sloan Digital Sky Survey (SDSS) in September 2005.

Key takeaways

J080107.90+435030.6 belongs to astronomy; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect J080107.90+435030.6 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of J080107.90+435030.6 from memory before moving on to harder problems.

Reference excerpt

J080107.90+435030.6 also known as 6C B075738+435851, is a radio galaxy in the constellation of Lynx. The redshift of the galaxy is (z) 0.255 and it was first discovered from a sample of 2,712 radio-loud active galactic nuclei in the Sloan Digital Sky Survey (SDSS) in September 2005.

Description J080107.90+435030.6 is a Fanaroff-Riley Class Type II radio galaxy. The total angular size of the source is 26 arcseconds while the total linear size is 103.25 kiloparsecs. There are no detections of either a radio core or hotspot features. A study published in 2016 found it is a broad-line radio galaxy. There are detections of both hydrogen-alpha and doubly ionized oxygen emission lines in its optical spectrum with estimated line luminosities of 6.899 and 6.740 L☉ respectively. The supermassive black hole residing in the center of the galaxy is found to 8.42 M☉, while the accretion disk luminosity is 43.79 erg s−1. A radio jet is present with an estimated power of 44.69 erg s−1. It is an X-shaped radio galaxy. The apparent r-band magnitude of the galaxy is 17.15, while the absolute magnitude is -23.06. It is also categorized as a bent-tailed radio galaxy which can be further classified as a wide angle-tail (WAT) radio galaxy. The total flux density at 1.4 GHz frequencies is 80.53 mJy while at 3 GHz frequencies, the flux density is 42.86 mJy. The curvature radius of the jet is 12.1 arcseconds. The g-r color value of the galaxy is 1.56 magnitude.

Illustrations

Worked examples

Example 1 — a first encounter with J080107.90+435030.6

Start with the simplest possible case. Write down what J080107.90+435030.6 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 J080107.90+435030.6 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 J080107.90+435030.6 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 J080107.90+435030.6

In research: J080107.90+435030.6 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 J080107.90+435030.6 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: J080107.90+435030.6 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Active galaxies, Astronomical objects discovered in 2005, LEDA objects, so understanding it makes those chapters shorter.
In everyday life: Look for J080107.90+435030.6 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.
