Searching for Galactic Hidden Gas through interstellar scintillation [PDF]
, 2009 International audienceConsidering the results of baryonic compact massive ob jects searches through microlensing [1], cool molecular hydrogen (H_2 - He) clouds should now be seriously considered as a possible major component of the Galactic hidden matter.

Different Polarized Components of the Quasar 3C 286 Revealed by FAST
The Astrophysical Journal3C 286, a well-known radio calibrator, exhibits stability in both total flux density and polarization parameters. However, its stable and luminous interstellar radio signal may encounter interplanetary scintillation (IPS) due to density irregularities in

Interstellar turbulence, random density variations, and scintillation measurements [PDF]
, 1985 The presence of random electron variations suggests that the ionized interstellar medium is turbulent. In the interstellar plasma the presence of power spectra of such variations extending to spatial scales much less than a Coulomb mean free path, Lambda

Simulation of the Interstellar scintillation of radio Pulsars. Characterization of Extreme Scattering Events toward the pulsar B1937+21. [PDF]
, 2003 We explore in this thesis work the model of the natural turbulent interstellar medium (ISM) as the origin of the Extreme Scattering Events (ESE). It is well known that the inhomogeneities of the ionized ISM closely match the Kolmogorov spatial spectrum ...

The Astrophysical JournalRecent radio surveys have revealed pulsars with dispersion and scattering delays induced by ionized gas that are larger than the rest of the observed pulsar population, in some cases with electron column densities (or dispersion measures, DMs) larger ...

Interstellar scattering of pulsar radiation. 1: Scintillation [PDF]
, 1974 An investigation of the intensity fluctuations of 28 pulsars near 0.4 GHz indicates that scintillation spectra have a Gaussian shape, scintillation indices are near unity, and the scintillation bandwidth depends linearly on dispersion measure ...

Scintillation in the Circinus Galaxy H2O Megamasers [PDF]
, 2005 We present observations of the 22 GHz water vapor megamasers in the Circinus galaxy made with the Tidbinbilla 70 m telescope. These observations confirm the rapid variability seen earlier by Greenhill et al.
