Consequently, a gravitational lens has no single focal point, but a focal line.
Akibatnya, sebuah lensa gravitasi tidak punya satu titik fokus, melainkan garis fokus.
In both cases the galaxies and sources are quite distant, many hundreds of megaparsecs away from the Milky Way Galaxy.
Dalam kedua kasus galaksi dan sumber cukup jauh, ratusan megaparsek dari galaksi kita.
Microlensing Where no distortion in shape can be seen but the amount of light received from a background object changes in time.
Pelensaan mikro: di mana tidak ada distorsi bentuk yang terlihat tetapi jumlah cahaya yang diterima dari objek latar berubah dari waktu ke waktu.
Gravitational lenses act equally on all kinds of electromagnetic radiation, not just visible light, and also in non-electromagnetic radiation, like gravitational waves.
Pelensaan gravitasi bertindak sama pada semua jenis radiasi elektromagnetik, tidak hanya cahaya tampak.
Weak lensing effects are being studied for the cosmic microwave background as well as galaxy surveys.
Efek pelensaan lemah sedang dipelajari untuk radiasi latar gelombang mikro kosmik maupun survei galaksi.
It was not until 1979 that the first gravitational lens would be discovered.
Tidak sampai tahun 1979 lensa gravitasi pertama ditemukan.
This gravitational lens was discovered by Dennis Walsh, Bob Carswell, and Ray Weymann using the Kitt Peak National Observatory 2.1 meter telescope.
Lensa gravitasi ini tak sengaja ditemukan oleh Dennis Walsh, Bob Carswell, dan Ray Weymann menggunakan teleskop 2,1 meter di Kitt Peak National Observatory.
In the 1980s, astronomers realized that the combination of CCD imagers and computers would allow the brightness of millions of stars to be measured each night.
Pada tahun 1980-an, para astronom menyadari bahwa paduan dari pencitra CCD dan komputer dapat memungkinkan terang dari jutaan bintang diukur tiap malam.
In a dense field, such as the galactic center or the Magellanic clouds, many microlensing events per year could potentially be found.
Pada tempat yang padat, seperti pusat galaksi atau awan Magellan, banyak even pelensaan mikro tiap tahun berpotensi untuk ditemukan.
This led to efforts such as Optical Gravitational Lensing Experiment, or OGLE, that have characterized hundreds of such events, including those of OGLE-2016-BLG-1190Lb and OGLE-2016-BLG-1195Lb.
Ini membawa pada usaha seperti Optical Gravitational Lensing Experiment, atau OGLE, yang mencirikan ratusan peristiwa yang demikian.
Most of the gravitational lenses in the past have been discovered accidentally.
Banyak lensa gravitasi dahulu ditemukan secara tidak sengaja.
A search for gravitational lenses in the northern hemisphere (Cosmic Lens All Sky Survey, CLASS), done in radio frequencies using the Very Large Array (VLA) in New Mexico, led to the discovery of 22 new lensing systems, a major milestone.
Pencarian lensa gravitasi di belahan bumi utara (Cosmic Lens All Sky Survey, CLASS), dilakukan pada frekuensi radio menggunakan Very Large Array (VLA) di New Mexico, membawa pada penemuan 22 sistem pelensaan baru, batu pijakan besar dalam sejarah lensa gravitasi.
This has opened a whole new avenue for research ranging from finding very distant objects to finding values for cosmological parameters so we can understand the universe better.
hal ini membuka jalan baru untuk riset dari pencarian benda yang sangat jauh sampai pencarian nilai parameter kosmologis agar pemahaman terhadap alam semesta menjadi lebih baik.
A similar search in the southern hemisphere would be a very good step towards complementing the northern hemisphere search as well as obtaining other objectives for study.
Pencarian yang sama di belahan bumi selatan akan menjadi langkah yang sangat baik untuk melengkapi pencarian di belahan bumi utara maupun mendapat hal lain untuk dipelajari.
The use of the Australia Telescope 20 GHz (AT20G) Survey data collected using the Australia Telescope Compact Array (ATCA) stands to be such a collection of data.
Penggunaan data Australia Telescope 20 GHz (AT20G) Survey dikumpulkan menggunakan Australia Telesope Compact Array (ATCA) merupakan kumpulan data yang demikian.
The AT20G survey is a blind survey at 20 GHz frequency in the radio domain of the electromagnetic spectrum.
Survei AT20G adalah survei buta pada frekuensi 20 GHz pada domain radio pada spektrum elektromagnetik.
Due to the high frequency used, the chances of finding gravitational lenses increases as the relative number of compact core objects (e.g. quasars) are higher (Sadler et al. 2006).
karena frekuensi tinggi yang dipakai, peluang menemukan lensa gravitasi menjadi lebih besar karena jumlah relatif dari objek inti kompak (contoh quasar) lebih tinggi (Sadler et al. 2006).
This search involves the use of interferometric methods to identify candidates and follow them up at higher resolution to identify them.
Pencarian ini melibatkan pengukuran interferometrik untuk mengenali calon dan mengikutinya pada resolusi lebih tinggi untuk mengidentifikasinya.
