Early Formation of Supermassive Black Holes via Dark Star Gravitational Instability
Katherine Freese, George M. Fuller, Sohan Ghodla +4
We show that dark stars, which are dark-matter-powered stars in the early universe, can grow by accretion to masses in the range $\mathscr{O}\left ({10}^4\right )-\mathscr{O}\left…
The evolution of accretor stars in binary systems due to accretion of increasingly helium-rich material
Sean Richards, Jan Eldridge, Sohan Ghodla +1
The recent discovery of examples of intermediate-mass helium stars have offered new insights into interacting binaries. These observations will allow significant improvements in ou…
Reconstructing PTA measurements via early seeding of supermassive black holes
Sohan Ghodla, Cosmin Ilie
Motivated by recent findings that PTA's nHz signal may be dominated by supermassive black hole (SMBH) binaries (), and high redshift quasar observations rev…
Galactic and extragalactic probe of dark matter with LISA's binary black holes
Sohan Ghodla
The upcoming LISA mission will be able to detect gravitational waves from galactic and extragalactic compact binaries. Here, we report on LISA's capability to probe dark matter aro…
