Core Scouring Dynamics and Gravitational Wave Consequences: Constraints on Supermassive Black Hole Binary Hardening

C. J. Harris, Kayhan Gultekin, Laura Blecha

We present a multi-messenger investigation of supermassive black hole binary (SBHB) hardening by jointly comparing models to the observed stellar mass deficits of nearby core galax…

Astro2020 Science White Paper: Black Holes Across Cosmic Time

Kayhan Gültekin, Aaron Barth, Karl Gebhardt +8

Supermassive black holes are located at the center of most, if not all, massive galaxies. They follow close correlations with global properties of their host galaxies (scaling rela…

Astro2020 Science White Paper: The Local Relics of of Supermassive Black Hole Seeds

Jenny E Greene, Aaron Barth, Andrea Bellini +18

We have compelling evidence for stellar-mass black holes (BHs) of ~5-80 M_sun that form through the death of massive stars. We also have compelling evidence for so-called supermass…

Astro2020 Science White Paper: Black Hole Growth in Mergers and Dual AGN

Michael Koss, Vivian U, Edmund Hodges-Kluck +13

Hierarchical models of galaxy formation predict that galaxy mergers represent a significant transitional stage of rapid supermassive black hole (SMBH) growth. Yet, the connection b…
