Also, we wish to thank all of the staff at La Silla in Chile and the ING staff at La Palma, Spain—scientific, technical and administration—for their assistance. Our work presents a new approach to modeling the local structure of the Galactic magnetic field. The DIB properties in the northern hemisphere. Agreement and J.T.v.L. Weilbacher, P. M. et al.

Next, we applied an analytical model for the ordered magnetic field in the shell to the modeled shell surface.

A.F. The Solar System has been traveling through the region currently occupied by the Local Bubble for the last five to ten million years. The Sun is embedded in the so-called Local Bubble (LB) - a cavity of hot plasma created by supernova explosions and surrounded by a shell of cold, dusty gas. This magnetic field model was successfully fitted to the Planck 353 GHz dust polarized emission maps over the Galactic polar caps. Sarre, P. J. We expect our methodology and our results to be useful both in modeling the local ISM as traced by its different components and in modeling the dust polarized emission, which is a long-awaited input for studies of the polarized foregrounds for cosmic microwave background. The origin of the local 1/4-keV X-ray flux in both charge exchange and a hot bubble. and for their support of the southern observations. Fuchs, B., Breitschwerdt, D., de Avillez, M.

Project overview and southern hemisphere survey.

The history and future of the local and loop I bubbles. Knowing the local distortion of the Galactic magnetic field associated with the LB is critical for the modeling of interstellar polarization data at high Galactic latitudes.

For each polar cap, the direction of the mean magnetic field derived from dust polarization (together with the prior that the field points toward longitude 90° ± 90°) is found to be consistent with the Faraday spectra of the nearby diffuse synchrotron emission.

The asymmetric shape of the local bubble is simulated by introducing axial profiles for the density of the interstellar medium, such as exponential, Gaussian, inverse square dependence and Navarro-Frenk-White. We expanded the shell inner surface in spherical harmonics, up to a variable maximum multipole degree, which enabled us to control the level of complexity for the modeled surface.
