Spin-Orbit Misalignments of Eccentric Black Hole Mergers in AGN Disks
Gaia Fabj, Christopher Tiede, Connar Rowan +2
The disks of active galactic nuclei (AGNs) provide a natural environment where stellar-mass black holes (BHs) can dynamically pair, undergo repeated interactions, and eventually me…
Little Red Dots as self-gravitating discs accreting on supermassive stars: Spectral appearance and formation pathway of the progenitors to direct collapse black holes
Lorenz Zwick, Christopher Tiede, Lucio Mayer
We propose an alternative physical interpretation and formation pathway for the recently discovered "little red dots" (LRDs). We model LRDs as super-massive stars (SMSs) surrounded…
Dissecting environmental effects with eccentric gravitational wave sources
Lorenz Zwick, Kai Hendriks, David O'Neill +6
We model the effect of resonances between time-varying perturbative forces and the epi-cyclical motion of eccentric binaries in the gravitational wave (GW) driven regime. These ind…
Environmental effects in stellar mass gravitational wave sources I: Expected fraction of signals with significant dephasing in the dynamical and AGN channels
Lorenz Zwick, János Takátsy, Pankaj Saini +5
We present the first overview of the expected quantity of signals which will showcase significant gravitational wave phase shifts caused by astrophysical environments, considering…
