Arp 104

Arp 104, also known as Keenan's system, is entry 104 in Halton Arp's Atlas of Peculiar Galaxies catalog for spiral galaxy NGC 5216 and globular galaxy NGC 5218. The two galaxies are joined by a bridge of galactic material spanning 22 000 light years.

In 1790 William Herschel discovered the galaxies, and in 1926 they were studied by Edwin Hubble. In 1935 Philip C. Keenan first published a paper about the bridge connecting the galaxies, which was rediscovered in 1958 at the Lick and Palomar observatories.

History

The settlement now known as Arp was originally called Strawberry. The town was renamed for Bill Arp (pen name of Charles Henry Smith), a Georgia humorist who was nationally known in the late 19th century. The new name was supposedly chosen for its brevity, which allowed local strawberry producers to spend less time hand-marking their crates.

Krasue

The Krasue (Thai: กระสือ, /krà.sɯ̌ː/), known as Ahp (Khmer: អាប) in Cambodia and as Kasu (Lao: ກະສື, /ka.sɯ̌ː/) in Laos, is a nocturnal female spirit of Southeast Asian folklore. It manifests itself as a woman, usually young and beautiful, with her internal organs hanging down from the neck, trailing below the head.

According to Thai ethnographer Phraya Anuman Rajadhon, the Krasue consists of a floating head accompanied by a will-o'-the-wisp kind of luminescent glow. The explanations attempted about the origin of the glow include the presence of methane in marshy areas. The Krasue is often said to live in the same areas as Krahang, a male spirit of the Thai folklore.

This spirit moves about by hovering in the air above the ground, for it has no lower body. The throat may be represented in different ways, either as only the trachea or with the whole neck. The organs below the head usually include the heart and the stomach with a length of intestine, the intestinal tract emphasizing the ghost's voracious nature. In recent movie Krasue Valentine, this ghost is represented with more internal organs, such as lungs and liver, but much reduced in size and anatomically out of proportion with the head. The viscera are sometimes represented freshly daubed with blood, as well as glowing. In contemporary representations her teeth often include pointed fangs in yakkha (Thai: ยักษ์) or vampire fashion. In the movie Ghosts of Guts Eater she has a halo around her head.

NGC 4088

NGC 4088 is an intermediate spiral galaxy in the constellation Ursa Major. The galaxy forms a physical pair with NGC 4085, which is located 11′ away.

NGC 4088 is a grand design spiral galaxy. This means that the spiral arms in the galaxy's disk are sharply defined. In visible light, one of the spiral arms appears to have a disconnected segment. Halton Arp included this galaxy in the Atlas of Peculiar Galaxies as one of several examples where this phenomenon occurs.

NGC 4088 and NGC 4085 are members of the M109 Group, a group of galaxies located in the constellation Ursa Major. This large group contains between 41 and 58 galaxies, including the spiral galaxy M109.

Supernova 2009dd

On April 13, 2009, SN 2009dd was discovered in NGC 4088. At apparent magnitude 13.8, it became the 3rd brightest supernova of 2009. In 1991 there was SN1991G.
