A Coherent Timing Solution for the Nearby, Thermally Emitting Isolated Neutron Star RX J0420.0-5022
David L. Kaplan, Marten H. van Kerkwijk
We present a phase-coherent timing solution for RX J0420.0-5022, the coolest (kT=45 eV) and fastest-spinning (P=3.45 s) of the seven so-called isolated neutron stars (INSs). Using…
New Optical/UV Counterparts and the Spectral Energy Distributions of Nearby, Thermally Emitting, Isolated Neutron Stars
David L. Kaplan, Atish Kamble, Marten H. van Kerkwijk +1
We present Hubble Space Telescope optical and ultraviolet photometry for five nearby, thermally emitting neutron stars. With these measurements, all seven such objects have confirm…
Blindly Detecting Merging Supermassive Black Holes with Radio Surveys
David L. Kaplan, Richard O'Shaughnessy, Alberto Sesana +1
Supermassive black holes presumably grow through numerous mergers throughout cosmic time. During each merger, supermassive black hole binaries are surrounded by a circumbinary accr…
