The Fan Region is one of the dominant features in the polarized radio sky, long thought to be a local (distance . 500 pc) synchrotron feature. We present 1.3 − 1.8 GHz polarized radio continuum observations of the region from the Global Magneto-Ionic Medium Survey (GMIMS) and compare them to maps of Hα and polarized radio continuum intensity from 0.408 − 353 GHz. The high-frequency (> 1 GHz) an...
We prove that the strong polarized relation ( 2 μ )
the conditional formal potential, e°′of methyldopa has been studied by cyclic voltammetry at the surface of activated glassy carbon electrode (agce) as the working electrode in different ph phosphate buffered solutions. the experimental standard redox potential, e°′, of methyldopa is obtained to be 0.72 mv versus she (standard hydrogen electrode). e°′ values have also been calculated with the a...
We present a full-sky model of polarized Galactic microwave emission based on three years of observations by the Wilkinson Microwave Anisotropy Probe (WMAP) at frequencies from 23 to 94 GHz. The model compares maps of the Stokes Q and U components from each of the 5 WMAP frequency bands in order to separate synchrotron from dust emission, taking into account the spatial and frequency dependence...
In our previous paper, we have reported the detection of a Balmer edge absorption feature in the polarized flux of one quasar (Ton 202). We have now found similar Balmer edge features in the polarized flux of four more quasars (4C09.72, 3C95, B2 1208+32, 3C323.1), and possibly a few more, out of 14 newly observed with the VLT and Keck telescopes. In addition, we also re-observed Ton 202, but we...
The Southern Galactic Plane Survey (SGPS) is a radio survey in the 21 cm H I line and in 1.4 GHz full-polarization continuum, observed with the Australia Telescope Compact Array and the Parkes 64m single dish telescope. The survey spans a Galactic longitude of 253 < l < 358 and a latitude of |b| < 1 at a resolution of 100 arcsec and a sensitivity below 1 mJy/beam. This paper presents interferom...
A model of wavelength-dependent lags in optical continuum variability of AGNs is proposed which avoids the problems of the popular “lamppost” model. Rather than being due to reprocessing of high-energy radiation from a hypothetical source above the accretion disk, the wavelength-dependent delays observed from the B to I bands are instead due to contamination of an intrinsically coherently varia...
We propose a bipolar jet model for supernova polarization. Light from the main component of the supernova (which we call the bulk supernova for short) scatters off electrons in the jets and is polarized: this polarized light is added to the direct emission from the bulk supernova and causes the overall supernova emission to be polarized. The motivation for the bipolar jet model is to resolve th...
