A detailed X-ray investigation of zeta Puppis I. The dataset and some preliminary results
Yael Naze, Carlos Arturo Flores, Gregor Rauw
Aims: zeta Puppis, one of the closest and brightest massive stars, was the first early-type object observed by the current generation of X-ray observatories. These data provided so…
A note on the FKPP equation approached with the hyperbolic scaling
M. A. Reyes, H. C. Rosu
We consider the hyperbolic scaling of the FKPP equation and introduce two solutions of the action functional type in the limit of zero hyperbolic parameter. Furthermore, we show th…
Renormalization of the QED of second order spin 1/2 fermions
Rene Angeles-Martinez, Mauro Napsuciale
In this work we study the renormalization of the electrodynamics of spin 1/2 fermions in the Poincaré projector formalism which is second order in the derivatives of the fields. We…
Two long HI tails in the outskirts of Abell 1367
T. C. Scott, L. Cortese, E. Brinks +3
We present VLA D-array HI observations of the RSCG42 and FGC1287 galaxy groups, in the outskirts of the Abell 1367 cluster. These groups are projected ~ 1.8 and 2.7 Mpc west from t…
Cosmological Bianchi Class A models in Sáez-Ballester theory
J. Socorro, Paulo A. Rodríguez, Abraham Espinoza-García +2
We use the Sáez-Ballester (SB) theory on anisotropic Bianchi Class A cosmological model, with barotropic fluid and cosmological constant, using the Hamilton or Hamilton-Jacobi appr…
On Deformed Phase Space and
E. Mena, S. Pérez-Payán, M. Sabido
In this letter we study the effects of a noncommutative in the phase space of an empty (4+1) Kaluza-Klein universe with cosmological constant. We analyze the effects of the noncomm…
