космічні струни, фазовий перехід у ранньому Всесвіті, ультрарелятивістська плазма, швидкі радіоспалахи, FRB 121102Résumé
Космічні струни – топологічні дефекти, релікти раннього Всесвіту, які могли формуватися під час фазових переходів полів зі спонтанно порушеною симетрією. Було показано, що позагалактичні швидкі радіоспалахи можна пояснити як випромінювання від надпровідних космічних струн. У рамках нашої моделі було досліджено FRB 121102 – вперше зареєстрований повторюваний швидкий радіоспалах. Для кількох груп подій спалаху був отриманий параметр, який характеризує можливе джерело випромінювання – петлю космічної струни, а саме енергетичний масштаб фазового переходу, під час якого дана струна утворилась
