Cusps in the center of galaxies: a real conflict with observations or a numerical artefact of cosmological simulations?
A. N. Baushev, L. del Valle, L. E. Campusano +3
Galaxy observations and N-body cosmological simulations produce conflicting dark matter halo density profiles for galaxy central regions. While simulations suggest a cuspy and univ…
Super massive black holes in star forming gaseous circumnuclear discs
Luciano del Valle, Andres Escala, Cristian Maureira-Fredes +3
Using N-body/SPH simulations we study the evolution of the separation of a pair of SMBHs embedded in a star forming circumnuclear disk (CND). This type of disk is expected to be fo…
Binary Disk interaction II: Gap-Opening criteria for unequal mass binaries
Luciano del Valle, Andres Escala
We study the interaction between an unequal mass binary with an isothermal circumbinary disk, motivated by the theoretical and observational evidence that after a major merger of g…
Gravitational Fragmentation in Galaxy Mergers: A Stability Criteria
Andres Escala, Fernando Becerra, Luciano del Valle +1
We study the gravitational stability of gaseous streams in the complex environment of a galaxy merger, because mergers are known to be places of ongoing massive cluster formation a…
Last giant impact on the Neptunian system. Constraints on oligarchic masses in the trans-Saturnian region
M. Gabriela Parisi, Luciano del Valle
Stochastic impacts by large bodies are, at present, the usually accepted mechanisms able to account for the obliquity of the ice giants. We attempt to set constraints on giant impa…
