Design, analysis and test of a microdots apodizer for the Apodized Pupil Lyot Coronagraph
P. Martinez, C. Dorrer, E. Aller Carpentier +4
Coronagraphic techniques are required to detect exoplanets with future Extremely Large Telescopes. One concept, the Apodized Pupil Lyot Coronagraph (APLC), is combining an apodizer…
High variability in Vela X-1: giant flares and off states
Ingo Kreykenbohm, Joern Wilms, Peter Kretschmar +6
We investigate the spectral and temporal behavior of the high mass X-ray binary Vela X-1 during a phase of high activity, with special focus on the observed giant flares and off st…
Suzaku and XMM-Newton Observations of Diffuse X-ray Emission from the Eastern Tip Region of the Carina Nebula
Yuichiro Ezoe, Kenji Hamaguchi, Robert A. Gruendl +3
The eastern tip region of the Carina Nebula was observed with the Suzaku XIS for 77 ks to conduct a high-precision spectral study of extended X-ray emission. XMM-Newton EPIC data o…
Galaxy Clusters in the Swift/BAT era: Hard X-rays in the ICM
M. Ajello, P. Rebusco, N. Cappelluti +6
We report about the detection of 10 clusters of galaxies in the ongoing Swift/BAT all-sky survey. This sample, which comprises mostly merging clusters, was serendipitously detected…
A novel method for measuring the extragalactic background light: Fermi application to the lobes of Fornax A
Markos Georganopoulos, Rita M. Sambruna, Demosthenes Kazanas +5
We describe a new method for measuring the extragalactic background light (EBL) through the detection of -ray inverse Compton (IC) emission due to scattering of the EBL photons…
Cosmic X-ray background and Earth albedo Spectra with Swift/BAT
M. Ajello, J. Greiner, G. Sato +8
We use Swift/BAT Earth occultation data at different geomagnetic latitudes to derive a sensitive measurement of the Cosmic X-ray background (CXB) and of the Earth albedo emission i…
