Supergugus Saraswati: Perbedaan antara revisi

'''Supergugus Saraswati''' adalah sebuah [[supergugus]] masif yang terletak sekitar 1,2 gigaparsek (4.000 juta [[tahun cahaya]]) dari area [[Stripe 82]], [[Sloan Digital Sky Survey|SDSS]], di arah [[konstelasi]] [[Pisces (rasi bintang)|Pisces]].<ref name=Bagchi2017>{{cite journal|url=http://iopscience.iop.org/article/10.3847/1538-4357/aa7949|doi=10.3847/1538-4357/aa7949|arxiv=1707.03082|volume=844|pages=25|title=Saraswati: An Extremely Massive ~ 200 Megaparsec Scale Supercluster|year=2017|first1=Joydeep|last1=Bagchi|first2=Shishir|last2=Sankhyayan|first3=Prakash|last3=Sarkar|first4=Somak|last4=Raychaudhury|author-link4=Somak Raychaudhury|first5=Joe|last5=Jacob|first6=Pratik|last6=Dabhade|access-date = 2017-07-30|journal=The Astrophysical Journal|bibcode = 2017ApJ...844...25B }}</ref><ref>{{cite web|url=https://elpais.com/elpais/2017/07/13/ciencia/1499967116_043113.html|title=Descubierta Sarasvati, una de las mayores estructuras del universo|language=es|date=14 JulyJuli 2017|access-date=14 July 2017|publisher=[[El País]]}}</ref> Supergugus ini merupakan salah satu [[Daftar struktur kosmis terbesar|struktur terbesar]] yang ditemukan di [[Alam semesta teramati|alam semesta]], dengan diameter sumbu mayor sekitar 200 Mpc (652 juta tahun cahaya).

Supergugus Saraswati dan lingkungan sekitarnya mengungkapkan bahwa beberapa peningkatan skala materiik skala besar yang ekstrem telah terbentuk di masa lalu ketika [[energi gelap]] baru saja mulai mendominasi pembentukan struktur. Konsentrasi galaksi ini menyoroti peran energi gelap dan kondisi awal kosmologis dalam pembentukan supergugus.<ref name=NewScientist>{{cite web | title = Galaxy supercluster is one of the biggest things in the universe | date = 14 July 2017 | url = https://www.newscientist.com/article/2140847-galaxy-supercluster-is-one-of-the-biggest-things-in-the-universe/ | access-date = 12 JanuaryJanuari 2018 | archive-url = https://web.archive.org/web/20171008104633/https://www.newscientist.com/article/2140847-galaxy-supercluster-is-one-of-the-biggest-things-in-the-universe/ | archive-date = 8 OctoberOktober 2017 | website = NewScientist | last = Crane | first = Leah}}</ref><ref name=HuffPo>{{cite web | title = 'Saraswati': A Supercluster Of Galaxies Discovered By Indian Scientists | date = 14 July 2017 | url = http://www.huffingtonpost.in/2017/07/13/saraswati-a-supercluster-of-galaxies-discovered-by-indian-sci_a_23029293/ | access-date = 12 JanuaryJanuari 2018 | archive-url = https://web.archive.org/web/20170714091956/http://www.huffingtonpost.in/2017/07/13/saraswati-a-supercluster-of-galaxies-discovered-by-indian-sci_a_23029293/ | archive-date = 14 JulyJuli 2017 | website = HuffingtonPost| last = | first = }}</ref>
