Variable 21 cm absorption at z = 0 . 3127
We report multi-epoch GMRT HI observations of the z = 0.3127 damped absorber towards the quasar PKS 1127-145 , which reveal variability in both the absorption profile and the flux of the background source, over a timescale of a few days. The observed variations cannot be explained by simple inter-stellar scintillation (ISS) models where there are only one or two scintillating components and all...
متن کاملDrifting subpulse survey at 21 cm
We present the statistical results of a systematic, unbiased search for subpulse modulation of 187 pulsars performed with the Westerbork Synthesis Radio Telescope (WSRT) in the Netherlands at an observing wavelength of 21 cm (Weltevrede et al. 2006a). We have increased the list of pulsars that show the drifting subpulse phenomenon by 42, indicating that more than 55% of the pulsars that show th...
متن کاملHI 21 cm absorption at z ∼ 2 . 347 towards PKS B 0438 − 436
We report the detection of redshifted HI 21cm absorption in the z ∼ 2.347 damped Lymanα absorber (DLA) towards PKS B0438−436, with the Green Bank Telescope. This is the second-highest redshift at which 21cm absorption has been detected in a DLA. The absorption extends over ∼ 60 km s and has two distinct components, at z = 2.347477(12) and z = 2.347869(20). A similar velocity structure is seen i...
متن کاملHI 21 cm absorption at z ∼ 3 . 39 towards PKS 0201 + 113
We report the Giant Metrewave Radio Telescope detection of HI 21cm absorption from the z ∼ 3.39 damped Lyman-α absorber (DLA) towards PKS 0201+113, the highest redshift at which 21cm absorption has been detected in a DLA. The absorption is spread over ∼ 115 km s−1 and has two components, at z = 3.387144(17) and z = 3.386141(45). The stronger component has a redshift and velocity width in agreem...
متن کاملSETHI@Berkeley– A Piggyback 21-cm Sky Survey at Arecibo
SETI@home observes a 2.5 MHz bandwidth centered on 1420 MHz near the 21-cm line using a short line feed at Arecibo which provides a 6 beam. This feed sits on Carriage House 1, which means that during normal astronomical observations with the new Gregorian dome the feed scans across the sky at twice the sidereal rate. We are using the SETI@home receiver to obtain about 4 4 106 spectra per year w...
