XMM-Newton observations of the Seyfert 1 AGN H0557-385
C. E. Ashton, M. J. Page, G. Branduardi-Raymont +1
We present XMM-Newton observations of the Seyfert 1 AGN H0557-385. We have conducted a study into the warm absorber present in this source, and using high-resolution RGS data we fi…
The nature and origin of Seyfert warm absorbers
A. J. Blustin, M. J. Page, S. V. Fuerst +2
We collate the results of recent high resolution X-ray spectroscopic observations of 23 AGN, and use the resulting information to try to provide answers to some of the main open qu…
XMM-Newton observations of warm absorbers in PG quasars
C. E. Ashton, M. J. Page, A. J. Blustin +5
We present XMM-Newton EPIC observations of warm absorbers in the quasars PG 1114+445 and PG 1309+355, both of which exhibit evidence for absorption by warm material in the line-of-…
Gravitational microlensing of planets: the influence of planetary phase and caustic orientation
Ceri E. Ashton, Geraint F. Lewis
Recent studies have demonstrated that detailed monitoring of gravitational microlensing events can reveal the presence of planets orbiting the microlensed source stars. With the po…
