WSRT detection of HI absorption in the z=3.4 damped Ly alpha system in PKS 0201+113

Publikováno v: Astronomy & astrophysics, 305(2), 450-456. EDP Sciences

We report the detection of a faint narrow HI absorption line at a redshift of 3.38 against the quasar PKS 0201+113 which itself has an emission redshift of 3.61. The absorption line redshift agrees, to within the errors, with that of a damped Ly alph

The very luminous millisecond binary radio pulsar PSR J0218+4232 has been detected in soft X-rays, at a luminosity of 8.4 x 10(32)erg s(-1) between 0.1 - 2.4 keV. The EGRET source 2EG J0220+4228 has a position which is consistent with that of PSR J02

FAINT RADIO-SOURCES WITH PEAKED SPECTRA .1. VLA OBSERVATIONS OF A NEW SAMPLE WITH INTERMEDIATE FLUX-DENSITIES

Autor: SNELLEN, IAG, ZHANG, M, SCHILIZZI, RT, ROTTGERING, HJA, DEBRUYN, AG, MILEY, GK

Publikováno v: Astronomy & astrophysics, 300(2), 359-365. EDP Sciences

We present 2 and 20 cm observations with the VLA of 25 candidate peaked spectrum radio sources. These data combined with those from earlier surveys have allowed us to construct radio spectra spanning a range of frequency from 0.3 to 15 GHz. Ten of th
