Sterile neutrinos in light of recent cosmological and oscillation data: A multi-flavor scheme approach (2009)
Journal Article
Melchiorri, A., Mena, O., Palomares-Ruiz, S., Pascoli, S., Slosar, A., & Sorel, M. (2009). Sterile neutrinos in light of recent cosmological and oscillation data: A multi-flavor scheme approach. Journal of Cosmology and Astroparticle Physics, 2009(01), Article 036. https://doi.org/10.1088/1475-7516/2009/01/036

Light sterile neutrinos might mix with the active ones and be copiously produced in the early Universe. In the present paper, a detailed multi-flavor analysis of sterile neutrino production is performed. Making some justified approximations allows us...

The Chandra Deep protocluster survey : evidence for an enhancement of AGN activity in the SSA22 protocluster at z = 3.09 (2009)
Journal Article
Lehmer, B., Alexander, D., Geach, J., Smail, I., Basu-Zych, A., Bauer, F., …Yamada, T. (2009). The Chandra Deep protocluster survey : evidence for an enhancement of AGN activity in the SSA22 protocluster at z = 3.09. Astrophysical Journal, 691(1), 687-695. https://doi.org/10.1088/0004-637x/691/1/687

We present results from a new ultra-deep ≈400 ks Chandra observation of the SSA22 protocluster at z = 3.09. We have studied the X-ray properties of 234 z ~ 3 Lyman Break Galaxies (LBGs; protocluster and field) and 158 z = 3.09 Lyα Emitters (LAEs) in...

Manipulation of quantum particles in rapidly oscillating potentials by inducing phase hops (2009)
Journal Article
Ridinger, A., & Weiss, C. (2009). Manipulation of quantum particles in rapidly oscillating potentials by inducing phase hops. Physical Review A, 79(1), https://doi.org/10.1103/physreva.79.013414

Analytical calculations show that the mean motion of a quantum particle trapped by a rapidly oscillating potential can be significantly manipulated by inducing phase hops—i.e., by instantaneously changing the potential’s phase. A phase hop can be vis... Read More about Manipulation of quantum particles in rapidly oscillating potentials by inducing phase hops.
