Does AGN feedback trigger star formation?
Active galactic nuclei are some of the most luminous objects in the universe. This paper explores how feedback from AGN could trigger star formation in their host galaxies.
QUIET, please…we’re observing the CMB
The QUIET telescope has been observing the CMB, looking for the gravitational wave background. Will it find the “smoking gun” for the theory of inflation?
Interstellar Lithium in the Small Magellanic Cloud
What can a nearby dwarf galaxy tell us about the the chemical evolution of the universe?
Viewing the Zodiacal Light
The zodiacal light may look beautiful, but it can get in the way of important observations. This paper suggests improvements to models of the dust cloud using observations from the Spitzer Space Telescope.
Polarization in Stacked X-ray Imaging Detectors
Why are there so few X-ray imaging polarimeters? This paper determines the intrinsic sensitivity of stacked imaging detectors to hard X-ray polarization.
