Constraining Brans-Dicke Gravity with Millisecond Pulsars in Ultracompact Binaries
Dimitrios Psaltis
The five accreting, millisecond X-ray pulsars in ultracompact binaries that were recently discovered with the Rossi X-ray Timing Explorer provide excellent candidates for constrain…
Accreting Neutron Stars and Black Holes: A Decade of Discoveries
Dimitrios Psaltis
This is a review of recent observational and theoretical developments related to accreting neutron stars and black holes in binary systems.
Testing Strong-field Gravity with Quasi-Periodic Oscillations
Simon DeDeo, Dimitrios Psaltis
The frequencies of quasi-periodic oscillations around neutron stars are believed to be related to characteristic frequencies in the gravitational fields of the compact objects. In…
Photon Scattering by Relativistic Flows in Schwarzschild Spacetimes. I. The Generation of Power-Law Spectra
H. Papathanassiou, D. Psaltis
We study the spectra generated as a result of bulk Comptonization by relativistic electrons in radial flows onto compact objects. We solve numerically the general-relativistic radi…
Hydrodynamic Effects on the QPO Frequencies of Accreting Compact Objects
Dimitrios Psaltis
The variability properties of accreting compact objects predicted by dynamical models are characterized by a number of distinct frequencies that are specific to each model. Because…
On the Origin of Quasi-Periodic Oscillations and Broad-band Noise in Accreting Neutron Stars and Black Holes
Dimitrios Psaltis, Colin Norman
Accreting neutron stars and black holes share a number of rapid variability characteristics, such as quasi-periodic oscillations and broad-band noise. The frequencies of these feat…
