An Optical Study of the Black Widow Population
D. Kandel, Roger W. Romani
The optical study of the heated substellar companions of `Black Widow' (BW) millisecond pulsars (MSP) provides unique information on the MSP particle and radiation output and on th…
PSR J0952-0607: The Fastest and Heaviest Known Galactic Neutron Star
Roger W. Romani, D. Kandel, Alexei V. Filippenko +2
We describe Keck-telescope spectrophotometry and imaging of the companion of the ``black widow" pulsar PSR~J09520607, the fastest known spinning neutron star (NS) in the disk of…
XMM-Newton Observes the Intrabinary Shock of PSR J1959+2048
D. Kandel, Roger W. Romani, Hongjun An
In a multi-orbit (100 ks) exposure of the original black widow pulsar, PSR J1959+2048, we measure the strong orbital modulation caused by intrabinary shoc…
PSR J1810+1744: Companion Darkening and a Precise High Neutron Star Mass
Roger W. Romani, D. Kandel, Alexei V. Filippenko +2
Keck-telescope spectrophotometry of the companion of PSR J1810+1744 shows a flat, but asymmetric light-curve maximum and a deep, narrow minimum. The maximum indicates strong gravit…
Discovery of a Gamma-ray Black Widow Pulsar by GPU-accelerated Einstein@Home
L. Nieder, C. J. Clark, D. Kandel +39
We report the discovery of 1.97 ms period gamma-ray pulsations from the 75 minute orbital-period binary pulsar now named PSR J1653-0158. The associated Fermi Large Area Telescope g…
On the vanishing orbital X-ray variability of the eclipsing binary millisecond pulsar 47 Tuc W
Pavan R. Hebbar, Craig O. Heinke, D. Kandel +2
Redback millisecond pulsars (MSPs) typically show pronounced orbital variability in their X-ray emission due to our changing view of the intrabinary shock (IBS) between the pulsar…
