Sentences with phrase «galactic dust as»

Not exact matches

The BICEP2 instrument can not distinguish the cosmic contribution from other sources directly, so, measurements of galactic dust collected by other sources, such as the Planck satellites were used.

Other effects, such as light scattering from cosmic dust and the synchrotron radiation generated by electrons moving around galactic magnetic fields within our own galaxy, can also produce these polarisation twists.

Our black hole's violent meeting with G2 began last year, and as it continues, it should give astronomers a chance to peer inside the galactic center — the neighborhood around the black hole — rather than just simulate the swirling disc of gas and dust surrounding it.

For tens of millions of years, most have been far from the galactic disc where dust and gas resides, so heavy elements such as calcium should have sunk beyond detection long before.

But teasing out this primordial signal is difficult, as swirls in the CMB could also be caused by galactic dust, and confidence had started to wane by the official publication of the BICEP2 results in June.

Dust grains in the Galaxy could imprint a similar polarization pattern in the CMB as gravitational waves can, but based on several different predictions of the galactic contribution the researchers concluded that their data was more likely to originate from primordial gravitational waves.

A popular theory known as the «unified theory» suggests that differences in the brightness of active galactic nuclei, as seen from here on Earth, are due to the placement of this donut of obscuring dust relative to our angle of observation.

The bright center band in the above image represents heated interstellar dust as seen along the galactic plane of the Milky Way.

Many active galactic nuclei are surrounded by large, dark, donut - shaped clouds of gas and dust, as seen in this artist's rendering.

«Detecting the Rayleigh signal is challenging because the frequency range where Rayleigh scattering has the biggest effect is contaminated by «noise» and foregrounds, such as galactic dust,» lead author Elham Alipour said.

As a result, many specific structural features of the spiral arms are not well known, especially when compared with other spirals observed outside the Milky Way such as Andromeda (which is located a few million ly above the galactic plane of obscuring dust in the Milky Way's disAs a result, many specific structural features of the spiral arms are not well known, especially when compared with other spirals observed outside the Milky Way such as Andromeda (which is located a few million ly above the galactic plane of obscuring dust in the Milky Way's disas Andromeda (which is located a few million ly above the galactic plane of obscuring dust in the Milky Way's disk.

As for NGC2976, an extended dust component is observed along the minor axis, which shows a distribution somewhat asymmetrical to the galactic disk; this might be associated with the HI bridge in the M81 / M82 group that NGC2976 belongs to.
