Design of a CZT Gamma-Camera for GRB and Fast Transient Follow-up: a Wide-Field-Monitor for the EDGE Mission (2008)

Natalucci, L., Feroci, M., Quadrini, E., Ubertini, P., Piro, L., Herder, J. W. Den, ...

The success of the SWIFT/BAT and INTEGRAL missions has definitely opened a new window for follow-up and deep study of the transient gamma-ray sky. This now appears as the access key to important...

EDGE: Explorer of Diffuse emission and Gamma-ray burst Explosions (2007)

Piro, L., Herder, J. W. Den, Ohashi, T.

How structures on various scales formed and evolved from the early Universe up to present time is a fundamental question of astrophysical cosmology. EDGE will trace the cosmic history of the baryons...

Status of the XMM-Newton cross-calibration with SASv6.5.0 (2005)

Stuhlinger, M., Altieri, B., Baskill, D., Dennerl, K., Esquej, M. P., Freyberg, M., ...

Further achievements of the XMM-Newton cross-calibration - XMM internal as well as with other X-ray missions - are presented. We explain the major changes in the new version SASv6.5 of the XMM-Newton...

XMM-Newton EPIC and OM Observations of Her X-1 over the 35 d Beat Period and an Anomalous Low State (2005)

Zane, S., Ramsay, G., Jimenez-Garate, M. A., Herder, J. W. Den, Still, M., Boyd, P. T., ...

We present the results of a series of XMM-Newton EPIC and OM observations of Her X-1, spread over a wide range of the 35 d precession period. We confirm that the spin modulation of the neutron star...

The interstellar oxygen-K absorption edge as observed by XMM-Newton (2003)

De Vries, C. P., Herder, J. W. Den, Boggende, A. J. Den, Rasmussen, A. P.

High resolution X-ray spectra of the Reflection Grating Spectrometer (RGS) on board the XMM satellite are used to resolve the oxygen K absorption edge. By combining spectra of low and high extinction...

XMM-Newton confirmation of Soft X-ray excess emission in clusters of galaxies - the discovery of O VII emission from an extended warm baryonic component (2002)

Kaastra, J. S., Lieu, R., Tamura, T., Paerels, F. B. S., Herder, J. W. Den

We investigate a sample of 14 clusters of galaxies observed with XMM-Newton in a search for soft X-ray excess emission. In five of these clusters a significant soft excess is evident. This soft X-ray...

High Resolution Soft X-ray Spectroscopy of M87 with the Reflection Grating Spectrometers on XMM-Newton (2002)

Sakelliou, I., Peterson, J. R., Tamura, T., Paerels, F. B. S., Kaastra, J. S., Belsole, E., ...

We present high-resolution X-ray spectroscopic observations of M87 with the Reflection Grating Spectrometers on XMM-Newton. We detect strong K-shell line emission from N, O, Ne, Mg, some emission...

High-Resolution X-ray Spectroscopy of Hercules X-1 with the XMM-Newton RGS: CNO Element Abundance Measurements and Density Diagnostics of a Photoionized Plasma (2002)

Jimenez-Garate, M. A., Hailey, C. J., Herder, J. W. Den, Zane, S., Ramsay, G.

We analyze the high-resolution X-ray spectrum of Hercules X-1, an intermediate-mass X-ray binary, which was observed with the XMM-Newton Reflection Grating Spectrometer. We measure the elemental...

X-ray line emission in Hercules X-1 (2002)

Jimenez-Garate, M. A., Hailey, C. J., Herder, J. W. Den, Zane, S., Ramsay, G.

We find line emission from the hydrogen- and/or helium-like ions of Ne, O, N and C in the low and short-on states of Her X-1, using the XMM-Newton Reflection Grating Spectrometer. The emission line...

XMM-Newton EPIC observations of Her X-1 (2002)

Ramsay, G., Zane, S., Jimenez-Garate, M. A., Herder, J. W. Den, Hailey, C. J.

We present spin-resolved X-ray data of the neutron star binary Her X-1. We find evidence that the Iron line at 6.4 keV originates from the same location as the blackbody X-ray component. The line...

Can a Dusty Warm Absorber Model Reproduce the Soft X-ray Spectra of MCG-6-30-15 and Mrk 766? (2001)

Sako, M., Kahn, S. M., Branduardi-Raymont, G., Kaastra, J. S., Brinkman, A. C., Page, M. J., ...

XMM-Newton RGS spectra of MCG-6-30-15 and Mrk 766 exhibit complex discrete structure, which was interpreted in a paper by Branduardi-Raymont et al. (2001) as evidence for the existence of...
