Probing the formation of the seeds of supermassive black holes with gravitational waves

Understand

The existence of black holes in the intermediate mass interval between one hundred and ten thousand solar masses, filling the gap between the stellar and the supermassive black holes is a key prediction to explain the origin of luminous QSOs at redshifts as large as seven.

• There is a sheer difficulty in forming giant black holes of billion suns in less than one billion years.
• This has led to the concept of seed black holes.
• They are high redshift intermediate mass black holes that formed during cosmic dawn.
