APAKAH MAKSUD SEYFERT GALAXY dalam CORSICA?

Galaksi Seyfert

Seyfert galaxy

Galaksi Seyfert adalah salah satu daripada dua kumpulan galaksi aktif, bersama dengan quasar. Mereka mempunyai nukleus seperti quasar dengan kecerahan permukaan yang sangat tinggi yang spektrumnya menunjukkan garis pelepasan yang kuat dan tinggi, tetapi tidak seperti quasar, galaksi tuan rumah mereka dapat dikesan dengan jelas. Seyfert galaksi menyumbang kira-kira 10% daripada semua galaksi dan merupakan sebahagian daripada objek yang paling banyak dikaji dalam astronomi, kerana ia dianggap dapat dikuasai oleh fenomena yang sama yang terjadi di quasar, walaupun mereka lebih dekat dan kurang bercahaya daripada quasar. Galaksi-galaksi ini mempunyai lubang hitam supermasif di pusat-pusat mereka yang dikelilingi oleh cakera akrilik bahan yang jatuh. Cakilan akrilik dipercayai menjadi sumber radiasi ultraviolet yang diperhatikan. Pelepasan ultraviolet dan penyerapan menyediakan diagnosis terbaik untuk komposisi bahan sekitar. Dilihat dalam cahaya yang kelihatan, kebanyakan galaksi Seyfert kelihatan seperti galaksi spiral yang normal, tetapi apabila dikaji di bawah panjang gelombang yang lain, menjadi jelas bahawa kecerahan teras mereka adalah keamatan yang setanding dengan kecerahan seluruh galaksi saiz Bima Sakti.

Seyfert galaxies are one of the two largest groups of active galaxies, along with quasars. They have quasar-like nuclei with very high surface brightnesses whose spectra reveal strong, high-ionisation emission lines, but unlike quasars, their host galaxies are clearly detectable. Seyfert galaxies account for about 10% of all galaxies and are some of the most intensely studied objects in astronomy, as they are thought to be powered by the same phenomena that occur in quasars, although they are closer and less luminous than quasars. These galaxies have supermassive black holes at their centres which are surrounded by accretion discs of in-falling material. The accretion discs are believed to be the source of the observed ultraviolet radiation. Ultraviolet emission and absorption lines provide the best diagnostics for the composition of the surrounding material. Seen in visible light, most Seyfert galaxies look like normal spiral galaxies, but when studied under other wavelengths, it becomes clear that the luminosity of their cores is of comparable intensity to the luminosity of whole galaxies the size of the Milky Way.
