The Swift Deep Galactic Plane Survey (DGPS) Phase I Catalog

The Astrophysical Journal Supplement Series, 2023
The Swift Deep Galactic Plane Survey (DGPS) is a Swift Key Project consisting of 380 tiled pointings covering ∼40 deg ^2 of the Galactic plane between longitude 10 < ∣ l ∣ < 30 deg and latitude ∣ b ∣ < 0.5 deg. Each pointing has a 5 ks exposure, yielding

X-ray irradiation of the winds in binaries with massive components

, 2015
Binaries with hot massive components are strong X-ray sources. Besides the intrinsic X-ray emission of individual binary members originating in their winds, X-ray emission stems from the accretion on the compact companion or from wind collision.

X-Ray Binaries in External Galaxies

, 2023
X-ray appearance of normal galaxies is mainly determined by X-ray binaries powered by accretion onto a neutron star or a stellar mass black hole. Their populations scale with the star-formation rate and stellar mass of the host galaxy and their X-ray luminosity distributions show a significant split between star-forming and passive galaxies, both facts

A Comprehensive Study of Thermonuclear X-Ray Bursts from 4U 1820–30 with NICER: Accretion Disk Interactions and a Candidate Burst Oscillation

The Astrophysical Journal
We present the results obtained from timing and spectral studies of 15 thermonuclear X-ray bursts from 4U 1820–30 observed with the Neutron Star Interior Composition Explorer (NICER) during its 5 yr of observations between 2017 and 2022.

Outer jet X-ray and radio emission in R Aquarii: 1999.8 to 2004.0

, 2007
Chandra and VLA observations of the symbiotic star R Aqr in 2004 reveal significant changes over the three to four year interval between these observations and previous observations taken with the VLA in 1999 and with Chandra in 2000.

Power Spectra of X‐Ray Binaries [PDF]

The Astrophysical Journal, 2002
The interpretation of Fourier spectra in the time domain is critically examined. Power density spectra defined and calculated in the time domain are compared with Fourier spectra in the frequency domain for three different types of variability: periodic signals, Markov processes and random shots.

XMM-Newton View of Pulsating Iron Fluorescent Emission from Centaurus X-3

The Astrophysical Journal
Centaurus X–3 (Cen X–3) is a bright, high-mass X-ray binary pulsar. We present a pulse phase–resolved X-ray spectral analysis of data from an archival XMM-Newton observation of Cen X–3 taken during the high state of the source.

M 33 X-7: ChASeM33 reveals the first eclipsing black hole X-ray binary [PDF]

, 2006
The first observations conducted as part of the Chandra ACIS survey of M 33 (ChASeM33) sampled the eclipsing X-ray binary M 33 X-7 over a large part of the 3.45 d orbital period and have resolved eclipse ingress and egress for the first time.
