Detecting Obscured AGN in the Distant Universe with Spitzer
J. L. Donley, G. H. Rieke, P. G. Perez-Gonzalez +2
We present the results of a Spitzer search for obscured AGN in the Chandra Deep Field-North, using both radio-excess and mid-infrared power-law selection. AGN selected via the form…
Time relaxation of interacting single--molecule magnets
J. F. Fernandez, J. J. Alonso
We study the relaxation of interacting single--molecule magnets (SMMs) in both spatially ordered and disordered systems. The tunneling window is assumed to be, as in Fe8, much narr…
Expressions for the number of J=0 pairs in even-even Ti isotopes
L. Zamick, A. Escuderos, S. J. Lee +4
We count the number of pairs in the single j-shell model of {44}Ti for various interactions. For a state of total angular momentum I, the wave function can be written in terms of t…
Comment on "Hole digging in ensembles of tunneling molecular magnets"
J. J. Alonso, J. F. Fernandez
Tupitsyn et al. [Phys. Rev. B v69, 132406 (2004)] have recently reported results for the relaxation of crystalline systems of single--molecule magnets, such as Fe_8. They claim tha…
How systems of single-molecule magnets magnetize at low temperatures
J. F. Fernandez, J. J. Alonso
We model magnetization processes that take place through tunneling in crystals of single-molecule magnets, such as Mn_12 and Fe_8. These processes take place when a field H is appl…
Multiple Point-Symmetric Ejections in IC 4634
Martin A. Guerrero, Luis F. Miranda, You-Hua Chu
We present a spatio-kinematical study of the planetary nebula (PN) IC 4634 which has experienced several episodes of point-symmetric ejections oriented at different directions. The…
