Roulette Inflation with Kähler Moduli and their Axions
J. R. Bond, L. Kofman, S. Prokushkin +1
We study 2-field inflation models based on the ``large-volume'' flux compactification of type IIB string theory. The role of the inflaton is played by a Kähler modulus τcorrespondi…
Polarization from aligned atoms as a diagnostics of circumstellar, AGN and interstellar magnetic fields: II. Atoms with Hyperfine Structure
Huirong Yan, A. Lazarian
We show that atomic alignment presents a reliable way to study topology of astrophysical magnetic fields. The effect of atomic alignment arises from modulation of the relative popu…
Holography and the scale-invariance of density fluctuations
Joao Magueijo, Lee Smolin, Carlo R. Contaldi
We study a scenario for the very early universe in which there is a fast phase transition from a non-geometric, high temperature phase to a low temperature, geometric phase describ…
Large Structures and Galaxy Evolution in COSMOS at z < 1.1
N. Scoville, H. Aussel, A. Benson +25
We present the first identification of large-scale structures (LSS) at z in the Cosmic Evolution Survey (COSMOS). The structures are identified from adaptive smoothing of g…
Black Hole Formation in X-Ray Binaries: The Case of XTE J1118+480
T. Fragos, B. Willems, N. Ivanova +1
In recent years, an increasing number of proper motions have been measured for Galactic X-ray binaries. When supplemented with accurate determinations of the component masses, orbi…
Direct Measurement of the Ratio of Carbon Monoxide to Molecular Hydrogen in the Diffuse Interstellar Medium
Eric B. Burgh, Kevin France, Stephan R. McCandliss
We have used archival far-ultraviolet spectra from observations made by HST/STIS and FUSE to determine the column densities and rotational excitation temperatures for CO and H2, re…
