Abstract
In this study, we
investigate gravitational lensing by rotating wormholes in the braneworld framework. By deriving the deflection angle for
a rotating wormhole spacetime with extra-dimensional contributions, we analyze
how rotation and braneworld effects modify lensing
signatures. The metric incorporates a rotational
parameter
Keywords: Braneworld gravity; deflection angle;
extra dimensions; gravitational lensing; rotating wormholes
Abstrak
Dalam penyelidikan ini, kami mengkaji kanta graviti oleh lohong cecacing berputar dalam kerangka dunia bran. Dengan menerbitkan sudut pesongan bagi ruang masa lohong cecacing berputar yang mempunyai sumbangan daripada dimensi tambahan, kami menganalisis bagaimana kesan putaran dan dunia bran mengubah ciri kanta graviti. Metrik yang digunakan menggabungkan suatu parameter putaran, manakala sudut pesongan yang terhasil merangkumi sumbangan tambahan yang timbul daripada pembetulan dunia bran berdimensi tambahan. Hasil yang diperoleh buat pertama kalinya, menunjukkan sumbangan gandingan antara putaran dan pembetulan dunia bran terhadap sudut pesongan, termasuk kebergantungan eksplisit kepada faktor pengembangan, yang tidak terdapat dalam kajian putaran terdahulu. Pembetulan ini membezakan lohong cecacing dunia bran daripada analognya dalam kerelatifan am, sekali gus menawarkan pandangan baharu dalam membezakan lohong cecacing berputar daripada lohong hitam serta menguji kosmologi dunia
bran melalui kanta graviti.
Kata kunci: Dimensi tambahan; graviti dunia bran; kanta graviti; lohong cecacing berputar; sudut pesongan
