SDSS J092712.65+294344.0: Recoiling Black Hole or A Sub-parsec Binary Candidate?
Tamara Bogdanovic, Michael Eracleous, Steinn Sigurdsson
A search for recoiling supermassive black hole candidates recently yielded the best candidate thus far, SDSS J092712.65+294344.0 reported by Komossa et al. Here we propose the alte…
Modeling of Emission Signatures of Massive Black Hole Binaries: I Methods
Tamara Bogdanovic, Britton D. Smith, Steinn Sigurdsson +1
We model the electromagnetic signatures of massive black hole binaries (MBHBs) with an associated gas component. The method comprises numerical simulations of relativistic binaries…
Alignment of the spins of supermassive black holes prior to coalescence
Tamara Bogdanovic, Christopher S. Reynolds, M. Coleman Miller
Recent numerical relativistic simulations of black hole coalescence suggest that in certain alignments the emission of gravitational radiation can produce a kick of several thousan…
Electromagnetic Signatures of Massive Black Hole Binaries
Tamara Bogdanovic, Britton D. Smith, Michael Eracleous +1
We model the electromagnetic emission signatures of massive black hole binaries (MBHBs) with an associated gas component. The method comprises numerical simulations of relativistic…
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…
Tidal Disruption of a Star By a Black Hole : Observational Signature
Tamara Bogdanovic, Michael Eracleous, Suvrath Mahadevan +2
We have modeled the time-variable profiles of the Halpha emission line from the non-axisymmetric disk and debris tail created in the tidal disruption of a solar-type star by a mill…

Circumnuclear Shock and Starburst in NGC 6240: Near-IR Imaging and Spectroscopy with Adaptive Optics
Tamara Bogdanovic, Jian Ge, Claire E. Max +1
We have obtained adaptive optics, high spatial resolution (0.15 arcsecond) K-band spectra and images of the region around the two active nuclei in NGC 6240 which show the presence…
