IVS Products for Precise Global Reference Frames
W. Schluter, N. Vandenberg
VLBI plays a unique and fundamental role in the maintenance of global reference frames which are required for precise positioning in many research areas related e.g to the understa…
Densification of the International Celestial Reference Frame: Results of EVN Observations
P. Charlot, A. L. Fey, C. S. Jacobs +3
The current realization of the International Celestial Reference Frame (ICRF) comprises a total of 717 extragalactic radio sources distributed over the entire sky. An observing pro…
A Probe of the Matter Content of Quasar Jets
M. Georganopoulos, D. Kazanas, E. S. Perlman +1
We propose a method for estimating the matter content of quasar jets which exhibit Chandra - detected knots in their kpc scale jets. The method relies on measuring the component of…
SPI observations of positron annihilation radiation from the 4th galactic quadrant: Spectroscopy
V. Lonjou, G. Weidenspointner, J. Knodlseder +13
The status of the analysis of the electron/positron annihilation radiation performed by INTEGRAL/SPI in the 4th GALACTIC QUADRANT is reported. We use data from the first two Galact…
Classification and Characterization of Objects from GALEX and SDSS surveys
Luciana Bianchi, M. Seibert, W. Zheng +22
We use the GALEX (Galaxy Evolution Explorer) Medium Imaging Survey (MIS) and All-Sky Imaging Survey (AIS) data available in the first internal release, matched to the SDSS catalogs…
Recent Advances in X-ray Observations of Cataclysmic Variables
K. Mukai
A personal selection of noteworthy X-ray results on CVs are presented, with emphasis on XMM-Newton and Chandra observations. Progressing roughly from broad-band view to narrow-band…
