Complete Multiwavelength Characterization of Faint Chandra X-ray Sources Seen in the Spitzer Wide-Area IR Extragalactic (SWIRE) Survey
A. Franceschini, J. Manners, M. Polletta +24
We exploit deep combined observations with Spitzer and Chandra of the SWIRE survey in the ELAIS-N1 region, to investigate the nature of the faint X-ray and IR sources in common, to…
Triaxial haloes, intrinsic alignments and the dark matter power spectrum
R. E. Smith, P. I. R. Watts
(Abridged) We develop the halo model of large-scale structure to include triaxial dark matter haloes and their intrinsic alignments. As a direct application we derive general expre…
The classical dynamics of two-electron atoms near the triple collision
Min-Ho Lee, Gregor Tanner, Nark Nyul Choi
The classical dynamics of two electrons in the Coulomb potential of an attractive nucleus is chaotic in large parts of the high-dimensional phase space. Quantum spectra of two-elec…
Short time-scale optical variability of the dwarf Seyfert nucleus in NGC 4395
J. E. Skelton, A. Lawrence, A. Pappa +2
We present optical spectroscopic observations of the least-luminous known Seyfert 1 galaxy, NGC 4395, which was monitored every half-hour over the course of 3 nights. The continuum…
Totaro's question for G_2, F_4, and E_6
Skip Garibaldi, Detlev Hoffmann
In a 2004 paper, Totaro asked whether a G-torsor X that has a zero-cycle of degree d > 0 will necessarily have a closed etale point of degree dividing d, where G is a connected alg…
Resistance noise scaling in a 2D system in GaAs
R. Leturcq, G. Deville, D. L'Hote +3
The 1/f resistance noise of a two-dimensional (2D) hole system in a high mobility GaAs quantum well has been measured on both sides of the 2D metal-insulator transition (MIT) at ze…
