J-PAS
J-PAS (Javalambre Physics of the Accelerating universe Astrophysical Survey) is an astronomical survey is being carried out by the Astrophysical Observatory of Javalambre (OAJ), located in Pico del Buitre in Sierra de Javalambre, in Teruel, Spain. J-PAS officially started in the summer of 2023. OAJ is managed by Aragon Center for Physics of the Cosmos (CEFCA) and consists of two telescopes: a 2.5- metre primary mirror telescope (JST/T250) and an 80- centimeter telescope (JAST/T80). J-PAS is surveying the sky with JST/T250 telescope which has a 1.2 Giga-pixel camera, constituted by an array of 14 CCDs. J-PAS will observe more than 8000 square degrees (about 1/5 of the whole sky) in 57 filters during 5 to 6 years. J-PAS filters cover the entire visible region of the electromagnetic spectrum (3500 Å to 10000 Å) and can be classified as: * 54 narrow-band (roughly 14-nanometer width) filters. * 2 medium-band (roughly 50-nanometer width) filters; these are located on the extre ...

Astronomical Surveys
An astronomical survey is a general map or image of a region of the sky (or of the whole sky) that lacks a specific observational target. Alternatively, an astronomical survey may comprise a set of images, spectra, or other observations of objects that share a common type or feature. Surveys are often restricted to one band of the electromagnetic spectrum due to instrumental limitations, although multiwavelength surveys can be made by using multiple detectors, each sensitive to a different bandwidth. Surveys have generally been performed as part of the production of an astronomical catalog. They may also search for transient astronomical events. They often use wide-field astrographs. Scientific value Sky surveys, unlike targeted observation of a specific object, allow astronomers to catalog celestial objects and perform statistical analyses on them without complex corrections for selection effects. In some cases, an astronomer interested in a particular object will find ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nanometer
330px, Different lengths as in respect to the molecular scale. The nanometre (international spelling as used by the International Bureau of Weights and Measures; SI symbol: nm) or nanometer (American and British English spelling differences#-re, -er, American spelling) is a units of measurement, unit of length in the International System of Units (SI), equal to one billionth ( short scale) of a metre () and to 1000 picometres. One nanometre can be expressed in scientific notation as , and as metres. History The nanometre was formerly known as the millimicrometre – or, more commonly, the millimicron for short – since it is of a micron (micrometre), and was often denoted by the symbol mμ or (more rarely and confusingly, since it logically should refer to a ''millionth'' of a micron) as μμ. Etymology The name combines the SI prefix '' nano-'' (from the Ancient Greek , ', "dwarf") with the parent unit name ''metre'' (from Greek , ', "unit of measuremen ...

National Observatory (Brazil)
The National Observatory (Portuguese: ''Observatório Nacional'' or ''ON'') is an institution localized in Rio de Janeiro, Brazil. Founded by Pedro I on October 15, 1827, it is one of the oldest scientific institutions in the country. Its initial purpose was to guide the geographic studies of Brazil and teaching navigation. The institute is responsible for the Brazilian Official Time and performs various researches and studies in astronomy, astrophysics and geophysics. It offers postgraduate courses leading to master's and doctorate degree. History There has been astronomical observation in Brazil since the colonial times. According to Father Serafim Leite, the Jesuits installed an observatory in his school in Castle Hill in the Rio de Janeiro in 1730. In the same place, in 1780, Portuguese astronomers Sanches d'Orta and Oliveira Barbosa set up an observatory and began to perform regular observations of astronomy, meteorology and terrestrial magnetism.

Charge-coupled Device
A charge-coupled device (CCD) is an integrated circuit containing an array of linked, or coupled, capacitors. Under the control of an external circuit, each capacitor can transfer its electric charge to a neighboring capacitor. CCD sensors are a major technology used in digital imaging. In a CCD image sensor, pixels are represented by p-doped metal–oxide–semiconductor (MOS) capacitors. These MOS capacitors, the basic building blocks of a CCD, are biased above the threshold for inversion when image acquisition begins, allowing the conversion of incoming photons into electron charges at the semiconductor-oxide interface; the CCD is then used to read out these charges. Although CCDs are not the only technology to allow for light detection, CCD image sensors are widely used in professional, medical, and scientific applications where high-quality image data are required. In applications with less exacting quality demands, such as consumer and professional digital camera ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
