A new list of extra-galactic radio jets
F. K. Liu, Y. H. Zhang
A catalogue of extra-galactic jets is very useful both in observational and theoretical studies of active galaxies. With the use of new powerful radio instruments, the detailed str…
AGNs among ROSAT Blank Field Sources
I. Cagnoni, M. Elvis, D. -W. Kim +3
We selected a sample of sources with high X-ray over optical flux ratio from the ROSAT PSPC archives. Out of the 16 sources in our sample, one is a (possibly extreme) BL Lac and tw…
Prospects for High Energy Studies of Pulsars with the AGILE Gamma-Ray Telescope
A. Pellizzoni, A. Chen, M. Conti +4
AGILE is a small gamma-ray astronomy satellite, with good spatial resolution, excellent timing capabilities and an unprecedented large field of view (~1/5 of the sky). It will be t…
A deep VLA survey at 6 cm in the Lockman Hole
P. Ciliegi, G. Zamorani, G. Hasinger +3
We have obtained a deep radio image with the Very Large Array at 6 cm in the Lockman Hole. The noise level in the central part of the field is about 11 microJy. From these data we…
Interstellar H_2 in M 33 detected with FUSE
Hartmut Bluhm, Klaas S. de Boer, Ole Marggraf +2
FUSE spectra of the four brightest H II regions in M 33 show absorption by interstellar gas in the Galaxy and in M 33. On three lines of sight molecular hydrogen in M 33 is detecte…
Mass-to-light ratios in early-type galaxies and the dark matter content
M. Capaccioli, N. R. Napolitano, M. Arnaboldi
The distribution of the radial trends of the mass-to-light ratios (M/L) within an assorted sample of early-type galaxies is discussed. Three classes of galaxies are identified acco…
