Where is the electrostatic self-energy localized in general relativity?
Carlos Barcelo, Jose Luis Jaramillo
We discuss an alternative way of prescribing the spacetime geometry associated with a non-radiating distribution of charged matter. It is based on the possibility that the electros…
The collimated outflows of the planetary nebula Hu1-2: proper motion and radial velocity measurements
L. F. Miranda, M. Blanco, M. A. Guerrero +1
Hu\,1-2 is a planetary nebula that contains an isolated knot located northwestern of the main nebula, which could be related to a collimated outflow. We present a subsarcsecond H$α…
Environmental effects in the interaction and merging of galaxies in zCOSMOS
P. Kampczyk, S. J. Lilly, L. de Ravel +56
(Abridged) We analyze the environments and galactic properties (morphologies and star-formation histories) of a sample of 153 close kinematic pairs in the redshift range 0.2 < z <…
Erratic Jet Wobbling in the BL Lacertae Object OJ287 Revealed by Sixteen Years of 7mm VLBA Observations
Ivan Agudo, Alan P. Marscher, Svetlana G. Jorstad +5
We present the results from an ultra-high-resolution 7mm Very Long Baseline Array (VLBA) study of the relativistic jet in the BL Lacertae object OJ287 from 1995 to 2011 containing…
Absolute dimensions of eclipsing binaries. XXIX. The Am-type systems SW Canis Majoris and HW Canis Majoris
G. Torres, J. V. Clausen, H. Bruntt +5
CONTEXT: Accurate physical properties of eclipsing stars provide important constraints on models of stellar structure and evolution, especially when combined with spectroscopic inf…
EChO - Exoplanet Characterisation Observatory
G. Tinetti, J. P. Beaulieu, T. Henning +131
A dedicated mission to investigate exoplanetary atmospheres represents a major milestone in our quest to understand our place in the universe by placing our Solar System in context…
