PSR

PSR may refer to:

Abell 1835 IR1916

Abell 1835 IR1916 (also known as Abell 1835, Galaxy Abell 1835, or Galaxy Abell 1835 IR1916) was a candidate for being the most distant galaxy ever observed, although that claim has not been verified by additional observations. It was claimed to lie behind the galaxy cluster Abell 1835, in the Virgo constellation.

Initial observation

Abell 1835 was discovered by French and Swiss astronomers of the European Southern Observatory, namely Roser Pelló, Johan Richard, Jean-François Le Borgne, Daniel Schaerer, and Jean-Paul Kneib. The astronomers used a near-infrared instrument on the Very Large Telescope to detect the galaxy; other observatories were then used to make an image of it possible. The Observatory, in conjunction with the Swiss National Science Foundation, the French Centre National de la Recherche Scientifique, and the journal Astronomy and Astrophysics, issued a press release on 1 March 2004 announcing the discovery. It was believed to be more distant than the galaxy lensed by Abell 2218.

PSR J1719-1438

PSR J1719-1438 is a millisecond pulsar with a spin period of 5.8 ms located about 4000 ly from Earth in the direction of Serpens Cauda, one minute from the border with Ophiuchus. Millisecond pulsars are generally thought to begin as normal pulsars and then spin up by accreting matter from a binary companion.

Diamond planet

PSR J1719-1438 was discovered in 2011 by the High Time Resolution Survey, a radio astronomy search for astronomical objects that rapidly vary in radio brightness, such as pulsars. Timing measurements using the Parkes Telescope and Lovell Telescope showed that it has a low-mass companion: PSR J1719-1438 b. The companion has a mass similar to that of Jupiter, but 40% of the diameter. It orbits the pulsar with a period of 2 hours 10 minutes and 37 seconds, at a distance of around 600,000 km (0.89 solar radii). The companion is likely the remnant of a star whose outer layers were siphoned off by the more massive pulsar. Calculations show the companion has a minimum density of 23 grams per cubic centimeter and is probably an ultra-low-mass carbon–oxygen white dwarf.

Cirrus (interbank network)

Cirrus is a worldwide interbank network operated by MasterCard Worldwide. Founded in 1982, it links MasterCard, Maestro, Diners Club credit, debit and prepaid cards to a network of over a million ATMs in 93 countries.

By default, Maestro cards are linked to the Cirrus network, but very often all three logotypes of the MasterCard family, MasterCard, Maestro and Cirrus, will be shown. Canadian, American, Venezuelan, Chilean and Saudi Arabian ATMs use this network alongside their local networks and many banks have adopted Cirrus as their international interbank network alongside either a local network, the rival Visa PLUS ATM network, or both. In locations such as India and Bangladesh, the Cirrus network also serves as a local interbank network as well as an international network.

Cirrus (Helsinki building)

Cirrus is a high-rise cooperative apartment building in Helsinki, the capital of Finland. Cirrus is the second tallest building in Finland with a height of 86 meters (282 feet). The building, which is located in Vuosaari in East Helsinki, has 28 floors (including two underground ones) and 140 apartments. The proposal for this building originally included a public observation terrace and cafe, but they were never built.

The building was designed by the Finnish architect company YIT Group and construction commenced in early 2005. The building reached its final height on 15 March 2006.

The roof was part of the setting of the music video of Finnish rock band Poets of the Fall's 2010 single Dreaming Wide Awake.
