Recent Progress in Calibration of the Rossi X-ray Timing Explorer Proportional Counter Array
We present the calibration and background model for the Proportional Counter Array on board the Rossi X-Ray Timing Explorer. The energy calibration is systematics-limited below 10 keV, withExpand

In-orbit performance and calibration of the Rossi X-ray Timing Explorer (RXTE) Proportional Counter Array (PCA)
The proportional counter array (PCA) is designed to perform microsecond timing of bright galactic sources and broad band, confusion limited, studies of faint extragalactic sources in the 2 - 60 keVExpand

An X-ray pulsar with a superstrong magnetic field in the soft γ-ray repeater SGR1806 − 20
Soft γ-ray repeaters (SGRs) emit multiple, brief (∼0.1-s), intense outbursts of low-energy γ-rays. They are extremely rare—three are known in our Galaxy and one in the Large Magellanic Cloud. TwoExpand

Millisecond X-Ray Variability from an Accreting Neutron Star System
We report the detection with the Proportional Counter Array (PCA) on board the Rossi X-Ray Timing Explorer (RXTE) of millisecond variability in the X-ray emission from the low-mass X-ray binary 4UExpand

The shear modulus of the neutron star crust and nonradial oscillations of neutron stars
Shear moduli are calculated for bcc crystalline and rapidly quenched Coulomb solids produced by the Monte Carlo simulation method. The shear moduli are calculated up to the transition temperature andExpand

Discovery of a Second Millisecond Accreting Pulsar: XTE J1751–305
We report the discovery by the Rossi X-Ray Timing Explorer Proportional Counter Array of a second transient accreting millisecond pulsar, XTE J1751-305, during regular monitoring observations of theExpand

Discovery of a Magnetar Associated with the Soft Gamma Repeater SGR 1900+14
The soft gamma repeater SGR 1900+14 became active again on 1998 June after a long period of quiescence; it remained at a low state of activity until 1998 August, when it emitted a series ofExpand

A Remarkable 3 Hour Thermonuclear Burst from 4U 1820–30
We present a detailed observational and theoretical study of a ~3 hr long X-ray burst (the "superburst") observed by the Rossi X-Ray Timing Explorer (RXTE) from the low-mass X-ray binary 4U 1820-30.Expand

PSR J0030+0451 Mass and Radius from NICER Data and Implications for the Properties of Neutron Star Matter
Neutron stars are not only of astrophysical interest, but are also of great interest to nuclear physicists because their attributes can be used to determine the properties of the dense matter inExpand

A NICER View of PSR J0030+0451: Millisecond Pulsar Parameter Estimation
We report on Bayesian parameter estimation of the mass and equatorial radius of the millisecond pulsar PSR J0030+0451, conditional on pulse-profile modeling of Neutron Star Interior CompositionExpand
