J1010+0612

J1010+0612 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 J1010+0612 rather than just read about it. In short: J1010+0612 also known as SDSS J101043.36+061201.4 is a radio-quiet type 2 quasar with an active galactic nucleus, located in the constellation of Sextans. The redshift of the galaxy is (z) 0.097 and it was first discovered by astronomers in December 2008.

Key takeaways

J1010+0612 belongs to astronomy; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect J1010+0612 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of J1010+0612 from memory before moving on to harder problems.

Reference excerpt

J1010+0612 also known as SDSS J101043.36+061201.4 is a radio-quiet type 2 quasar with an active galactic nucleus, located in the constellation of Sextans. The redshift of the galaxy is (z) 0.097 and it was first discovered by astronomers in December 2008.

Description J1010+0612 is classified as an early-type galaxy of type S0a based on optical imaging. It is interacting with a small companion that is located 13 kiloparsecs southwest from its position. The total star formation rate of the galaxy is estimated to be 30 M☉ per year based on its infrared luminosity. The radio morphology is compact, with a rounded nuclear component, whose total major axis is estimated to be 200 parsecs and at position angle 180° based on radio imaging made by the Very Large Array at 6 GHz frequencies. The carbon monoxide emission of the galaxy has a total radius of 2.4 kiloparsecs. There is a double structure present with a separation gap of 1.25 kiloparsecs between the peaks that are located in east to west. A dust lane is also present in the galaxy, located in a southwest direction from the central reddened nucleus. Studies have found there is a rotating disk of doubly ionized oxygen described as compact, with the major axis being -61°. There are broad wing features that have full width at half maximum of 1000 to 1200 kilometers per seconds and are blueshifted by -100 kilometers per second. Broad emission lines have also been discovered in the northwest direction. Further studies in 2024 have also discovered the line emission is mainly limited to an area of between seven and eight kiloparsecs from the nucleus position, and even beyond where the flux emission becomes faint. Kinematic hydrogen-alpha mapping has shown the emission is blueshifted southeast from the nucleus, with the velocity found closer to 50 kilometers per seconds from the northwest. The companion is being ionized by the emission. H2 rotation lines and polycyclic aromatic hydrocarbon emission have been detected in the galaxy as well.

Worked examples

Example 1 — a first encounter with J1010+0612

Start with the simplest possible case. Write down what J1010+0612 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 J1010+0612 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 J1010+0612 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 J1010+0612

In research: J1010+0612 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 J1010+0612 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: J1010+0612 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Active galaxies, Astronomical objects discovered in 2008, IRAS catalogue objects, so understanding it makes those chapters shorter.
In everyday life: Look for J1010+0612 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.
