On the baryonic, stellar, and luminous scaling relations of disk galaxies
V. Avila-Reese, J. Zavala, C. Firmani +1
We explore how the slopes and scatters of the scaling relations of disk galaxies (Vm-L[-M], R-L[-M], and Vm-R) do change when moving from B to K bands and to stellar and baryonic q…
Constraining the mSUGRA parameter space using the entropy of dark matter halos
Dario Nunez, Jesus Zavala, Lukas Nellen +3
We derive an expression for the entropy of a dark matter halo described by a Navarro-Frenk-White model with a core. The comparison of this entropy with the one of dark matter at th…
3D hydrodynamical simulations of the large scale structure of W50-SS433
Jesús Zavala, Pablo F. Velázquez, Adriano H. Cerqueira +1
We present 3D hydrodynamical simulations of a precessing jet propagating inside a supernova remnant (SNR) shell, particularly applied to the W50-SS433 system in a search for the or…
Stellar polytropes and Navarro-Frenk-White halo models: comparison with observations
Jesus Zavala, Dario Nunez, Roberto A. Sussman +2
Motivated by the possible conflict between the Navarro-Frenk-White(NFW) model predictions for the dark matter contents of galactic systems and its correlation with baryonic surface…
Entropy considerations in constraining the mSUGRA parameter space
Dario Nunez, Roberto A. Sussman, Jesus Zavala +3
We explore the use of two criteria to constraint the allowed parameter space in mSUGRA models. Both criteria are based in the calculation of the present density of neutralinos as d…
Pioneer anomaly? Gravitational pull due to the Kuiper belt
Jose A. de Diego, Dario Nunez, Jesus Zavala
In this work we study the gravitational influence of the material extending from Uranus orbit to the Kuiper belt and beyond on objects moving within these regions. We conclude that…
