C
Correct answer
Explanation
Govind Swarup was an Indian radio astronomer who made significant contributions to the study of galaxy formation. He is known for his work on the formation of dwarf galaxies, which are small galaxies that contain only a few billion stars.
Which Indian scientist is known for his work on the role of dark energy in galaxy formation?
-
Subrahmanyan Chandrasekhar
-
Jayant Narlikar
-
Govind Swarup
-
Harish-Chandra
B
Correct answer
Explanation
Jayant Narlikar is an Indian astrophysicist and cosmologist who has made significant contributions to the study of galaxy formation. He is known for his work on the role of dark energy in galaxy formation, which is the idea that galaxies are expanding at an accelerating rate due to the presence of a mysterious force called dark energy.
Which Indian scientist is known for his work on the formation of active galactic nuclei?
-

-
Jayant Narlikar
-
Govind Swarup
-
Harish-Chandra
C
Correct answer
Explanation
Govind Swarup was an Indian radio astronomer who made significant contributions to the study of galaxy formation. He is known for his work on the formation of active galactic nuclei, which are the bright centers of galaxies that are powered by the accretion of matter onto a supermassive black hole.
Which Indian astronomer proposed the theory of 'pulsating universe'?
