HALQASIMON GALAKTIKALARNING KLASSIFIKATSIYA MASALASI TAHLILI
##submission.downloads##
Mazkur maqolada zamonaviy kuzatuv ma’lumotlarini hisobga olgan holda fizik halqasimon galaktikalarni tasniflash masalasi qayta tadqiq qilindi. Ishda oxirgi yillarda kuzatilgan 8052 ta yangi halqasimon galaktika nomzodlari ro‘yxati ko‘rib chiqildi. Kuzatuv tasvirlari va morfologik belgilarni tekshirish natijasida ular orasidan 2774 ta obyekt fizik halqasimon galaktika sifatida saralandi. Ushbu tanlanma avvalgi tasniflash ishlarida o‘rganilgan obyektlar bilan birlashtirilib, 4144 ta fizik halqasimon galaktikadan iborat umumiy jamlanma shakllantirildi. Shakllantirilgan umumiy jamlanmadagi obyektlarning mavjud klassifikatsiya sinflariga mansubligi tahlil qilindi. Natijada fizik halqasimon galaktikalar 10 ta sinfga ajratildi. Tasniflash jarayonida markazida yadro va uning atrofida halqa kuzatiladigan galaktikalar ko‘pchilik guruhni tashkil etishi aniqlandi.
