What is a headtail?

1 : this side or that side —often used in plural in tossing a coin to decide a choice, question, or stake — compare heads or tails.

Who is the head of Galaxy?

What conditions result in a head tail radio galaxy?

Radio source sizes often 300 kpc or more — much bigger than their host galaxies. Head-tail radio galaxies arise when jets are bent by the ram-pressure of gas as the host galaxy moves through it.

What is head and tail in Indian coin?

The obverse of a coin is commonly called heads, because it often depicts the head of a prominent person, and the reverse tails.

What is a head in astronomy?

Almost everyone confuses the coma with the head of the comet, but the head, properly speaking, consists of both the coma and the nucleus. The glow from a comet’s coma is partly the light of the Sun, reflected from millions of tiny dust particles, and partly emissions of faint light from atoms and molecules in the coma.

What are the products of Galaxy Surfactants?

It offers its products under various categories, such as mild surfactants, including sodium Cocoyl Isethionate, Alkyl Polyglucoside and Sodium Lauryl Sarcosinate; surfactants, including Betaines and Lauryl Alcohol Eithoxylates; rheology modifier, including Cocomonoethanolamide and Cocodiethanolamide; conditioning …

What is the difference between Type 1 and Type 2 Seyfert galaxies?

Explanation: A Seyfert galaxy is a spiral galaxy with an active nucleus. Type I Seyfert galaxies are very bright sources of visible and ultraviolet light and x-rays. Type II Seyfert galaxies are very bright sources of infra-red and visible light.

Where is most of Milky Way’s dark matter located?

The visible disk of the Milky Way Galaxy is thought to be embedded in a much larger, roughly spherical halo of dark matter. The dark matter density drops off with distance from the galactic center.

Why is it called head and tail?

“Heads or tails” refers to the two sides of a coin, according to the Grammarist website. “Heads refers to the side of the coin with a person’s head on it. Tails refers to the opposite side, not because there is a tail on it, but because it is the opposite of heads.”

Which side is heads or tails?

Parts of a Coin The front side (“heads”) of a coin. The back side (“tails”) of a coin.

What are the 4 parts of a comet?

A comet is made up of four visible parts: the nucleus, the coma, the ion tail, and the dust tail. The nucleus is a solid body typically a few kilometres in diameter and made up of a mixture of volatile ices (predominantly water ice) and silicate and organic dust particles.

What is the biggest part of a comet?

nucleus
The nucleus is the main, solid part of the comet. The nucleus is usually 1 to 10 kilometers in diameter, but can be as big as 100 kilometers. It can be composed of rock. The coma is a halo of evaporated gas (water vapor, ammonia, carbon dioxide) and dust that surrounds the nucleus.

What kind of structures are found in radio galaxies?

Radio structures. Radio galaxies, and to a lesser extent, radio-loud quasars display a wide range of structures in radio maps. The most common large-scale structures are called lobes: these are double, often fairly symmetrical, roughly ellipsoidal structures placed on either side of the active nucleus.

How is the morphology of a radio galaxy determined?

With more detailed radio observations, the morphology turns out to reflect the method of energy transport in the radio source. FRI objects typically have bright jets in the centre, while FRIIs have faint jets but bright hotspots at the ends of the lobes.

What kind of radio emission does an active galaxy have?

Recently, much work has been done on the effects of these objects on the intergalactic medium, particularly in galaxy groups and clusters . The radio emission from radio-loud active galaxies is synchrotron emission, as inferred from its very smooth, broad-band nature and strong polarization.

Which is the most distant galaxy in the universe?

Recently, much work has been done on the effects of these objects on the intergalactic medium, particularly in galaxy groups and clusters. The most distant radio galaxy currently known is TGSS J1530+1049, at a redshift of 5.72.
