Type I X-ray bursts, burst oscillations and kHz quasi-periodic oscillations in the neutron star system IGR J17191-2821

D. Altamirano, M. Linares, A. Patruno +6

We present a detailed study of the X-ray energy and power spectral properties of the neutron star transient IGR J17191-2821. We discovered four instances of pairs of simultaneous k…

Near-infrared/optical identification of five low-luminosity X-ray pulsators

Ramanpreet Kaur, Rudy Wijnands, Biswajit Paul +2

We present the identification of the most likely near-infrared/optical counterparts of five low-luminosity X-ray pulsators (AX J1700.1-4157, AX 1740.1-2847, AX J1749.2-2725, AX J18…

Discovery of burst oscillations in the intermittent accretion-powered millisecond pulsar HETE J1900.1-2455

Anna L. Watts, Diego Altamirano, Manuel Linares +8

We report the discovery of burst oscillations from the intermittent accretion-powered millisecond pulsar (AMP) HETE J1900.1-2455, with a frequency approximately 1 Hz below the know…

The Observed Spin Distributions of Millisecond Radio and X-ray Pulsars

J. W. T. Hessels

We consider the currently observed spin distributions of various types of neutron stars, including isolated and binary radio millisecond pulsars in the Galactic plane and globular…

Discovery of a large and bright bow shock nebula associated with low mass X-ray binary SAX J1712.6-3739

K. Wiersema, D. M. Russell, N. Degenaar +6

In a multiwavelength program dedicated to identifying optical counterparts of faint persistent X-ray sources in the Galactic Bulge, we find an accurate X-ray position of SAX J1712.…
