Poyasnenie:
Bol'shinstvo galaktik imeet po odnomu
yadru – neuzheli u etoi galaktiki ih chetyre?
Astronomy dayut strannyi otvet: nastoyashego
yadra galaktiki na etom
snimke dazhe ne vidno.
Poyavlenie etogo izobrazheniya, pohozhego na
list klevera, vyzvano izlucheniem
kvazara fona.
Gravitacionnoe pole galaktiki, vidimoi na perednem
plane, fokusiruet svet udalennogo
kvazara
v vide chetyreh ego otdel'nyh izobrazhenii.
Dlya togo, chtoby poluchilsya
takoi mirazh,
sam kvazar dolzhen
nahodit'sya tochno pozadi centra massivnoi galaktiki.
Etot effekt nazyvaetsya
gravitacionnym linzirovaniem,
a dannyi konkretnyi sluchai – Krestom
Einshteina.
Stranno to, chto otnositel'naya yarkost'
Kresta Einshteina
menyaetsya, vremya ot vremeni povyshayas' za schet
dopolnitel'nogo effekta
gravitacionnogo
mikrolinzirovaniya ot
otdel'nyh zvezd galaktiki.
