Explaining the Orbits of the Galactic Center S-Stars
David Merritt, Alessia Gualandris, Seppo Mikkola
The young stars near the supermassive black hole at the galactic center follow orbits that are nearly random in orientation and that have an approximately thermal distribution of e…
Recovering the real-space correlation function from photometric redshift surveys
Pablo Arnalte-Mur, Alberto Fernández-Soto, Vicent J. Martínez +3
Measurements of clustering in large-scale imaging surveys that make use of photometric redshifts depend on the uncertainties in the redshift determination. We have used light-cone…
Sudden death and sudden birth of entanglement in common structured reservoirs
L. Mazzola, S. Maniscalco, J. Piilo +2
We study the exact entanglement dynamics of two qubits in a common structured reservoir. We demonstrate that, for certain classes of entangled states, entanglement sudden death occ…
Significant Limb-Brightening in the Inner Parsec of Markarian 501
B. Glenn Piner, Niraj Pant, Philip G. Edwards +1
We present three 43 GHz images and a single 86 GHz image of Markarian 501 from VLBA observations in 2005. The 86 GHz image shows a partially resolved core with a flux density of ab…
Off-resonant entanglement generation in a lossy cavity
F. Francica, S. Maniscalco, J. Piilo +2
We provide an exact and complete characterization of the entanglement dynamics of two qubits coupled to a common structured reservoir at zero temperature. We derive the conditions…
The origin of redshift asymmetries: How LambdaCDM explains anomalous redshift
Sami-Matias Niemi, Mauri Valtonen
Several authors have found a statistically significant excess of galaxies with higher redshifts relative to the group centre, so-called discordant redshifts, in particular in group…
