On Measuring Accurate 21 Cm Line Profiles with the Robert C. Byrd Green Bank Telescope
We use observational data to show that 21 cm line profiles measured with the Green Bank Telescope (GBT) are subject to significant inaccuracy. These include ∼10% errors in the calibrated gain and significant contribution from distant sidelobes. In addition, there are ∼60% variations between the GBT and Leiden/Argentine/Bonn 21 cm line profile intensities, which probably occur because of the hig...
متن کاملConstraining dark matter through 21 cm observations
Beyond reionization epoch cosmic hydrogen is neutral and can be directly observed through its 21 cm line signal. If dark matter (DM) decays or annihilates the corresponding energy input affects the hydrogen kinetic temperature and ionized fraction, and contributes to the Lyα background. The changes induced by these processes on the 21 cm signal can then be used to constrain the proposed DM cand...
متن کامل0 Cold gas , the HI 21 cm line and evolving galactic potentials
Neutral hydrogen traces gravitational potentials. In the nearby universe, 21cm emission-line surveys show that the bulk of the HI resides in well-formed, optically-luminous galaxies. At high redshift, 21cm line absorption against background radio quasars occurs in gas-rich systems identified with the highest HI column densities – the " damped Lyman alpha " quasar absorption-line systems. High s...
متن کاملHI 21 cm - line observations with the GMRT towards interstellar clouds previously seen in optical absorption
We have made HI 21cm-line absorption measurements using the GMRT towards 15 directions in the Galaxy which are known to have high random velocity clouds as seen in the optical absorption lines of CaII and NaI. For the first time, in 6 out of these 15 directions we detect HI absorption features corresponding to the high random velocity optical absorption lines. The mean optical depth of these de...
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...
