Nah, Teleskop Radio Bulat Aperture Lima ratus meter (FAST) kini mengambil sinyal ruang misterius yang dikenal sebagai ledakan radio cepat.<\/p>\n Ledakan radio cepat atau FRB adalah gelombang energi yang singkat namun kuat dari bagian kosmos yang jauh. Yang pertama terlihat pada tahun 2007, dan kami menemukan lebih banyak dari mereka sepanjang waktu.<\/p>\n Sementara para astronom baru-baru ini membuat beberapa kemajuan menarik dalam melacak FRB, kita hanya tidak tahu persis apa sinyal-sinyal ini, atau bagaimana mereka berasal. Mereka mungkin disebabkan oleh lubang hitam atau bintang neutron yang disebut magnetar, mungkin.<\/p>\n Apa yang menarik tentang deteksi oleh FAST adalah bahwa ledakan radio cepat ini adalah repeater. Ledakan ini secara resmi dikenal sebagai FRB 121102: pertama kali diambil pada tahun 2012 di Observatorium Arecibo di Puerto Rico, muncul beberapa kali sejak itu.<\/p>\n Para peneliti mencatat bahwa sinyal telah melakukan perjalanan sekitar 3 miliar tahun cahaya melintasi Semesta untuk mencapai kita.<\/p>\n FAST menempel FRB 121102 pada 30 Agustus, sebelum merekam lusinan pulsa kemudian (pada satu hari, 3 September, lebih dari 20 pulsa terdeteksi). Jadi, ini terlihat seperti FRB yang persisten.<\/p>\n Receiver 19-beam pada FAST sangat sensitif terhadap sinyal radio, yang mencakup rentang frekuensi 1,05-1,45 GHz, dan membuatnya sempurna untuk mengawasi FRB 121102.<\/p>\n Semakin banyak pengamatan yang dapat kita lakukan terhadap FRB ini, semakin baik peluang kita untuk bisa mengetahui apa sebenarnya FRB itu. Satu gagasan adalah bahwa FRB diproduksi berdasarkan disintegrasi kerak bintang neutron jenis tertentu.<\/p>\n Hipotesis lain menyatakan bahwa FRB yang berbeda sebenarnya memiliki penyebab yang berbeda, yang dapat menjelaskan mengapa FRB 121102 berulang dan yang lainnya tampaknya tidak melakukannya. Setidaknya kita menjadi lebih baik dalam menentukan dari mana datangnya ledakan radiasi elektromagnetik yang misterius ini.<\/p>\n Sekarang kita dapat menambahkan data yang dikumpulkan oleh FAST ke basis data pengetahuan kita yang sedang berkembang tentang fenomena ruang yang paling menarik ini. Tim di teleskop telah mampu menghilangkan gangguan pesawat dan satelit dari pengukuran mereka.<\/p>\n “Saya hanya berpikir itu sangat menakjubkan sehingga alam menghasilkan sesuatu seperti itu,” kata fisikawan Ziggy Pleunis dari McGill University kepada ScienceAlert, setelah membantu merinci delapan FRB baru dalam sebuah makalah yang diterbitkan bulan lalu.<\/p>\n “Juga, saya pikir ada beberapa informasi yang sangat penting dalam struktur itu sehingga kita hanya perlu mencari cara untuk menyandikan dan sangat menyenangkan untuk mencoba mencari tahu apa sebenarnya itu.”<\/p>\n
