The spin-foam-representation of loop quantum gravity
The problem of background independent quantum gravity is the problem of defining a quantum field theory of matter and gravity in the absence of an underlying...
SPIRE, the Spectral and Photometric Imaging Receiver, is Herschel's submillimetre camera and spectrometer. It comprises a three-band imaging photometer...
The Spitzer Survey of Stellar Structure in Galaxies (S4G)
We propose the ultimate survey of the distribution of stellar structure in the nearby universe using IRAC's 3.6 and 4.5 micron channels. Deep observations of...
The Spitzer-SWIRE Investigation of the "Tadpole" Galaxy
We present results from an investigation of the peculiar "Tadpole Galaxy" (UGC 10214) using mid-infrared imaging from the Spitzer Wide-area Infrared...
The Star Formation & Chemical Evolution Timescales of Two Nearby Dwarf Spheroidal Galaxies
We present wide-field photometry of resolved stars in the nearby Sculptor and Fornax dwarf spheroidal galaxies, going down to the oldest Main Sequence Turn-Off...
The Star Formation and Chemical Enrichment History of the Fornax dSph Galaxy
We present new deep color-magnitude diagrams (CMD) at two galactocentric distances, and Ca II triplet spectroscopy, of the Local Group dSph galaxy Fornax...
