Planck’s version of the CIB

Planck’s version of the CIB is quite startling as well – as I am sure many of you have seen some of the photos by now, for there is more information as Planck looks through voids in the milky way to see deeper…

Planck

Every spot in these images of the sky represents a point of light seen by Planck. On the left are objects within our own Galaxy, while on the right are other galaxies. On the left, the Galactic sources are almost all in the disc of our Galaxy, which is seen edge-on from Earth and lies across the centre of the image. There are loops and wisps of gas and dust above and below the Galactic Plane, which are generally parts of the Galaxy much closer to Earth. On the right, the Extragalactic sources are distributed all over the sky, though they cannot be seen through the Galactic Plane due to the gas and dust within our own Galaxy. The large spots below-right of the centre are the Magellanic Clouds, which are nearby, small galaxies which orbit our own. The background image in each is the Planck full-sky map, and the size of the points represents how bright they are when seen by Planck. Image credit: ESA/Planck Collaboration.

first six fields used to detect Cosmic Infrared

This image shows the location of the first six fields used to detect and study the Cosmic Infrared Background. The fields, named N1, AG, SP, LH2, Boötes 1 and Boötes 2, respectively, are all located at a relatively high galactic latitude, where the foreground contamination due to the Milky Way’s diffuse emission is less dramatic.

CIB taken by the Herschel Space Observatory

This week on JPL/Nasa, there is a pretty interesting article on THE COSMIC INFRARED BACKGROUND CIB with photos taken by the Herschel Space Observatory- this intrgiues me very much, as it is the infrared version of CMB – and well worth a read.

Herschel Measures Dark Matter for Star-Forming Galaxies

A region of the sky called the “Lockman Hole,” located in the constellation of Ursa Major, is one of the areas surveyed in infrared light by the Herschel Space Observatory. All of the little dots in this picture are distant galaxies. Image credit: ESA/Herschel/SPIRE/HerMES
