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…
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…
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…
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…
The effect of interstellar medium on LVK's black holes
Sohan Ghodla
Gravitational radiation alone is not efficient in hardening the orbit of a wide binary black hole (BBH). By employing a toy model for the interstellar medium (ISM) surrounding BBHs…
The effect of stellar rotation on black hole mass and spin
Sohan Ghodla, J. J. Eldridge
The gravitational wave signature of a binary black hole (BBH) merger is dependent on its component mass and spin. If such black holes originate from rapidly rotating progenitors, t…
Observational implications of cosmologically coupled black holes
Sohan Ghodla, Richard Easther, M. M. Briel +1
It was recently suggested that "cosmologically coupled" black holes with masses that increase in proportion to the volume of the Universe might constitute the physical basis of dar…
Sustained super-Eddington accretion around neutron stars & black holes
Sohan Ghodla, J. J. Eldridge
Recently, it was shown that the formation of a photon-trapping surface might not be sufficient to ensure unimpeded super-Eddington (SE) accretion. In light of this finding, here we…
Evaluating chemically homogeneous evolution in stellar binaries: Electromagnetic implications -- Ionizing photons, SLSN-I, GRB, Ic-BL
Sohan Ghodla, J. J. Eldridge, Elizabeth R. Stanway +1
We investigate the occurrence of rapid-rotation induced chemically homogeneous evolution (CHE) due to strong tides and mass accretion in binaries. To this end, we generalize the re…
VFTS 243 as predicted by the BPASS fiducial models
H. F. Stevance, S. Ghodla, S. Richards +3
The recent discovery of an unambiguous quiescent BH and main sequence O star companion in VFTS 243 opens the door to new constraints on theoretical stellar evolution and population…
Forward Modelling the O3(a+b) GW transient mass distributions with BPASS by varying compact remnant mass and SNe kick prescriptions
Sohan Ghodla, Wouter G. J. van Zeist, J. J. Eldridge +2
We present forward modeling from the BPASS code suite of the population of observed gravitational wave (GW) transients reported by the LIGO/VIRGO consortium (LVC) during their thir…
