Nauyaca: a new tool to determine planetary masses and orbital elements through transit timing analysis
Eliab F. Canul, Héctor Velázquez, Yilen Gómez Maqueo Chew
Transit Timing Variations (TTVs) is currently the most successful method to determine dynamical masses and orbital elements for Earth-sized transiting planets. Precise mass determi…
Assessing the Hierarchical Hamiltonian Splitting Integrator for Collisionless N-body Simulations
G. Aguilar-Argüello, O. Valenzuela, J. C. Clemente +2
The large dynamic range in some astrophysical N-body problems led to the use of adaptive multi-time-steps; however, the search for optimal strategies is still challenging. We numer…
GARROTXA Cosmological Simulations of Milky Way-sized Galaxies: General Properties, Hot Gas Distribution, and Missing Baryons
Santi Roca-Fàbrega, Octavio Valenzuela, Pedro Colín +5
We introduce a new set of simulations of Milky Way-sized galaxies using the AMR code ART + hydrodynamics in a CDM cosmogony. The simulation series is named GARROTXA and follow t…
On the galaxy spiral arms' nature as revealed by rotation frequencies
Santi Roca-Fàbrega, Octavio Valenzuela, Francesca Figueras +4
High resolution N-body simulations using different codes and initial condition techniques reveal two different behaviours for the rotation frequency of transient spiral arms like s…
The specific star formation rate and stellar mass fraction of low-mass central galaxies in cosmological simulations
V. Avila-Reese, P. Colín, A. González-Samaniego +4
(Abridged) By means of high-resolution cosmological simulations in the context of the LCDM scenario, the specific star formation rate (SSFR=SFR/Ms, Ms is the stellar mass)--Ms and…
