Black Hole Growth from Cosmological N-body Simulations
Miroslav Micic, Kelly Holley-Bockelmann, Steinn Sigurdsson
(Abridged) We use high resolution cosmological N-body simulations to study the growth of intermediate to supermassive black holes from redshift 49 to zero. We track the growth of b…
Role of Dynamical Research in the Detection and Characterization of Exoplanets
Eric B. Ford, Fred C. Adams, Phil Armitage +6
(Abridged) The discovery of extrasolar planetary systems revealed an unexpected diversity of planetary systems that has revolutionized planet formation theory. A strong program of…
Supermassive Black Hole Growth and Merger Rates from Cosmological N-body Simulations
Miroslav Micic, Kelly Holley-Bockelmann, Steinn Sigurdsson +1
Understanding how seed black holes grow into intermediate and supermassive black holes (IMBHs and SMBHs, respectively) has important implications for the duty-cycle of active galac…
Spitzer Search for Mid-IR Excesses Around Five DAZs
J. H. Debes, S. Sigurdsson
Hydrogen atmosphere white dwarfs with metals, so-called DAZs, require external accretion of material to explain the presence of weak metal line absorption in their photospheres. Th…
Observational Signature of Tidal Disruption of a Star by a Massive Black Hole
Tamara Bogdanovic, Michael Eracleous, Suvrath Mahadevan +2
We have modeled the time-variable profiles of the Balmer alpha emission from the nonaxisymmetric disk and debris tail created in the tidal disruption of a solar-type star by a mill…
Finding Extrasolar Planets in the Stellar Graveyard with the Hubble Space Telescope
John H. Debes, Steinn Sigurdsson, Bruce E. Woodgate
In order to directly image an extrasolar planet, the large contrast between a star and a companion planet must be overcome. White Dwarfs (WDs) are the remnants of stars > 1 M_sun a…
