We report on the results of a four-year long X-ray monitoring campaign of the central 1.2 square degrees of our Galaxy, performed with Chandra and XMM-Newton between 2005 and 2008. Our study focuses on the properties of transient X-ray sources that reach 2–10 keV luminosities of LX 10 34 erg s −1 for an assumed distance of 8 kpc. There are 17 known X-ray transients within the field of view of our campaign, eight of which were detected in outburst during our observations: the transient neutron… 
The recent discovery of a millisecond radio pulsar experiencing an accretion outburst similar to those seen in low mass X-ray binaries, has opened up a new opportunity to investigate the evolutionary
NuSTAR Hard X-Ray Survey of the Galactic Center Region. II. X-Ray Point Sources
We present the first survey results of hard X-ray point sources in the Galactic Center (GC) region by NuSTAR. We have discovered 70 hard (3–79 keV) X-ray point sources in a 0.6 deg^2 region around
The X-Ray Binary Population in the Galactic Center Revealed through Multi-decade Observations
We present an investigation of the quiescent and transient X-ray binaries (XRBs) of the Galactic Center (GC). We extended our Chandra analysis of the non-thermal X-ray sources, located in the central
The transient neutron star X-ray binary KS 1741–293 in outburst and quiescence
Abstract KS 1741–293 is a transient neutron star low-mass X-ray binary that is located at an angular distance of ≃20′ from the Galactic center. We map out the historic activity of the source since
NuSTAR Hard X-ray Survey of the Galactic Center Region I: Hard X-ray Morphology and Spectroscopy of the Diffuse Emission
We present the first sub-arcminute images of the Galactic Center above 10 keV, obtained with NuSTAR. NuSTAR resolves the hard X-ray source IGR J17456–2901 into non-thermal X-ray filaments, molecular
XMM-Newton observations of the Galactic Centre Region - II. The soft-thermal emission
We have extended our earlier study (Heard & Warwick 2013, Paper I) of the X-ray emission emanating from the central 100 pc x 100 pc region of our Galaxy to an investigation of several features
The XMM–Newton view of the central degrees of the Milky Way
The deepest XMM-Newton mosaic map of the central 1.5 deg of the Galaxy is presented, including a total of about 1.5 Ms of EPIC-pn cleaned exposures in the central 15" and about 200 ks outside. This
A peculiar thermonuclear X-ray burst from the transiently accreting neutron star SAX J1810.8–2609
Abstract We report on a thermonuclear (type-I) X-ray burst that was detected from the neutron star low-mass X-ray binary SAX J1810.8–2609 in 2007 with Swift. This event was longer (≃20 min) and more
Constraints On The Very Faint X-Ray Transient System M15 X-3
We present the first combined optical/X-ray observation of a very faint transient X-ray binary (VFXT), M15 X-3. Chandra observations constrain the source to be < 1034 erg s−1 in all observations. The


The XMM-Newton/Chandra monitoring campaign of the Galactic center region. Description of the program
We present the first results of our X-ray monitoring campaign on a 1.7 square degree region centered on Sgr A* using the satellites XMM-Newton and Chandra. The purpose of this campaign is to monitor
The behavior of subluminous X-ray transients near the Galactic center as observed using the X-ray telescope aboard Swift
In this paper we report on the spectral analysis of seven X-ray transients, which were found to be active during a monitoring campaign of the Galactic center carried out in 2006 and 2007 using the
A four-year baseline Swift study of enigmatic X-ray transients located near the Galactic center
We report on continued monitoring observations of the Galactic center carried out by the X-ray telescope aboard the Swift satellite in 2008 and 2009. This campaign revealed activity of the five known
Chandra Observations of the Bursting X-Ray Transient SAX J1747.0–2853 during Low-Level Accretion Activity
We present Chandra/ACIS observations of the bursting X-ray transient SAX J1747.0-2853 performed on 2001 July 18. We detected a bright source at the position of R.A. = 17h47m0260 and decl. =
A Chandra Catalog of X-Ray Sources in the Central 150 pc of the Galaxy
We present the catalog of X-ray sources detected in a shallow Chandra survey of the inner 2° × 08 of the Galaxy and in two deeper observations of the Radio Arches and Sgr B2. The catalog contains
X-Ray Sources with Periodic Variability in a Deep Chandra Image of the Galactic Center
We report the discovery of eight X-ray sources with periodic variability in 487 ks of observations of the Galactic center with Chandra. The sources are identified from a sample of 285 objects
ASCA X-Ray Source Catalog in the Galactic Center Region
The ASCA satellite made 107 pointing observations on a 5 × 5 deg2 region around the center of our Galaxy from 1993 to 1999. In the X-ray images of the 0.7-3 keV or 3-10 keV bands, we found 52 point
Discovery of a bright X-ray transient in the galactic center with XMM-Newton
We report the discovery of a bright X-ray transient object, XMMU J174554.4–285456, observed in outburst with XMM-Newton on October 3, 2002, and located at 6.3′ from Sgr A*, the supermassive black
The X-Ray Binary GRS 1741.9–2853 in Outburst and Quiescence
We report Chandra and XMM-Newton observations of the transient neutron star low-mass X-ray binary GRS 1741.9-2853. Chandra detected the source in outburst on 2000 October 26 at an X-ray luminosity of
XMM-Newton study of the persistent X-ray source 1E 1743.1-2843 located in the Galactic Center direction
The present spectral analysis does not rule out the hypothesis of a neutron star low-mass X-ray binary as suggested previously, and it is proposed that 1E 1743.1-2843 may be explained in terms of a black hole candidate in a low/hard state.
