Discovery of Two High-Magnetic-Field Radio Pulsars
V. M. Kaspi, F. Camilo, A. G. Lyne +5
We report the discovery of two isolated radio pulsars having the largest inferred surface dipole magnetic fields yet seen in the population: 4.1e10^13 G and 5.5e10^13 G. These puls…
VLBI observations of 3C273 at 22 GHz and 43 GHz. II: test of Synchrotron Self-Compton process
F. Mantovani, W. Junor, I. M. McHardy +1
The VLBI observations at 22 GHz and 43 GHz of the quasar 3C273 obtained during a multi-frequency campaign in late 1992 in the radio, millimetre and X-ray bands allow us to derive t…
The CERES Astronomical Database
Xanthopoulos, N. J. Jackson, I. Snellen +2
The CERES Astronomical Archive was created initially in order to make the large amount of data that were collected from the two surveys, the Jodrell-VLA Astrometric Survey (JVAS) a…
A Cluster Deficit in the ROSAT NEP Survey
Isabella Gioia
We have used data from the deepest region of the ROSAT All-Sky Survey, the North Ecliptic Pole (NEP) region, to produce a complete and unbiased X-ray selected sample of distant clu…
The Parkes Multibeam Pulsar Survey: preliminary results
N. D'Amico, A. G. Lyne, R. N. Manchester +7
A high-frequency survey of the Galactic plane for radio pulsars is in progress, using the multibeam receiver on the 64-m Parkes radiotelescope. We describe the survey motivations,…
The Parkes Multibeam Pulsar Survey: PSR J1811-1736 - a pulsar in a highly eccentric binary system
A. G. Lyne, F. Camilo, R. N. Manchester +8
We are undertaking a high-frequency survey of the Galactic plane for radio pulsars, using the 13-element multibeam receiver on the 64-m Parkes radio telescope. We describe briefly…
BeppoSAX observations of two high redshift clusters of galaxies: RXJ0152.7-1357 and MS2053.7-0449
R. Della Ceca, R. Scaramella, I. M. Gioia +3
We present X-ray observations of two high redshift clusters of galaxies carried out with the BeppoSAX satellite. One cluster, RXJ0152.7-1357 at z = 0.83, was selected from the ROSA…
The lives of FR I radio galaxies
P. Parma, M. Murgia, H. R. de Ruiter +1
After a brief introduction to the morphological properties of FRI radio sources, we discuss the possibility that FRI jets are relativistic at their bases and decelerate quickly to…
RXJ1716.6+6708: a protocluster at z=0.81?
Isabella M. Gioia
At z=0.809, RXJ1716.6+6708 is the second most distant X-ray selected cluster so far published and the only one with a large number of spectroscopically determined cluster member ve…
HI in four star-forming low-luminosity E/S0 and S0 galaxies
E. Sadler, T. Oosterloo, R. Morganti
We present HI data cubes of four low-luminosity early-type galaxies which are currently forming stars. These galaxies have absolute magnitudes in the range M_B=-17.9 to -19.9 (H_o=…
The radio structures of southern 2-Jy radio sources: new ATCA and VLA radio images
R. Morganti, T. Oosterloo, C. N. Tadhunter +3
We present new radio images obtained with the Australia Telescope Compact Array (ATCA) and the Very Large Array (VLA) for a group of 14 galaxies belonging to the 2-Jy sample of rad…
The Extreme Scattering Event Toward PKS 1741-038: VLBI Images
T. Joseph W. Lazio, A. L. Fey, Brian Dennison
(Abridged) We report multi-epoch VLBI observations of the source PKS 1741-038 as it underwent an extreme scattering event. Observations at four epochs were obtained, and images wer…
Restarting activity in radio galaxies
L. Lara, G. Giovannini, W. D. Cotton +5
We present observations of two radio galaxies, J1835+620 and 3C338, both with signs of having passed through different stages of core activity. The former presents two symmetric an…
The 408 MHz B3.1 Survey
M. Pedani, G. Grueff
We present a new 408 MHz survey (B3.1) carried out with the ''Croce del Nord'' radiotelescope in Bologna. The survey coordinates limits are to $+2^\circ 15^\pr…
Anisotropic inverse Compton scattering from the trans-relativistic to the ultra-relativistic regime and application to the radio galaxies
G. Brunetti
The problem of the anisotropic Inverse Compton scattering between a monochromatic photon beam and relativistic electrons is revisited and formally solved without approximations. So…
The galactic magnetic field in the quasar 3C216
T. Venturi, G. B. Taylor
Multifrequency polarimetric observations made with the Very Long Baseline Array of the quasar 3C216 reveal the presence of Faraday rotation measures (RMs) in excess of 2000 rad/m**…
