We present an X-ray study of our nearest starburst galaxy IC 10, based on XMM–Newton and Chandra observations. A list of 73 XMM–Newton and 28 Chandra detections of point-like X-ray sources in the fiel...
The XMM-Newton/Chandra monitoring campaign of the Galactic center region
Accretion accretion disks
2014/12/24
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 t...
We present an XMM–Newton observation of the massive edge-on Sb galaxy NGC 2613. We discover that this galaxy contains a deeply embedded active nucleus with a 0.3–10 keV luminosity of 3.3 × 1040 erg s&...
VLA and XMM-Newton Observations of the SNR W41/TeV Gamma-Ray Source HESS J1834–087
W41 HESS
2014/12/23
The recently discovered extended TeV source HESS J1834-087 is associated with both a diffuse X-ray enhancement and a molecular cloud, projected at the center of an old radio supernova remnant, G23.3-0...

2014/12/23
We present an X-ray study of the massive edge-on Sa galaxy, Sombrero (M 104; NGC 4594), based on XMM–Newton and Chandra observations. A list of 62 XMM–Newton and 175 Chandra discrete X-ray sources is ...
Detection of an ultra-bright submillimeter galaxy in the Subaru/XMM-Newton Deep Field using AzTEC/ASTE
AzTEC ASTE
2014/12/22
We report the detection of an extremely bright ($\sim$34 mJy at 1100 $\mu$m and $\sim$73 mJy at 880 $\mu$m) submillimeter galaxy (SMG), AzTEC-ASTE-SXDF1100.001 (hereafter referred to as SXDF1100.001),...
A remarkable long-term light curve, and deep, low-state spectroscopy: Swift & XMM-Newton monitoring of the NLS1 galaxy Mkn 335
remarkable long-term light curve low-state spectroscopy Swift XMM-Newton monitoring the NLS1 galaxy
2012/2/23
The Narrow-line Seyfert 1 galaxy (NLS1) Mkn 335 is remarkable because it has repeatedly shown deep, long X-ray low-states which show pronounced spectral structure. It has become one of the prototype A...
