Accurately simulating anisotropic thermal conduction on a moving mesh
Rahul Kannan, Volker Springel, Rüdiger Pakmor +2
We present a novel implementation of an extremum preserving anisotropic diffusion solver for thermal conduction on the unstructured moving Voronoi mesh of the AREPO code. The metho…
On the OVI Abundance in the Circumgalactic Medium of Low-Redshift Galaxies
Joshua Suresh, Kate H. R. Rubin, Rahul Kannan +3
We analyze the mass, temperature, metal enrichment, and OVI abundance of the circumgalactic medium (CGM) around galaxies of mass $10^9 M_\odot <M_\bigstar < 10^{11.5} M…
Towards a new classification of galaxies: principal component analysis of CALIFA circular velocity curves
Veselina Kalinova, Dario Colombo, Erik Rosolowsky +16
We present a galaxy classification system for 238 (E1-Sdm) CALIFA (Calar Alto Legacy Integral Field Area) galaxies based on the shapes and amplitudes of their circular velocity cur…
On the dependence of galaxy morphologies on galaxy mergers
Fabio Fontanot, Andrea V. Maccio', Michaela Hirschmann +4
The distribution of galaxy morphological types is a key test for models of galaxy formation and evolution, providing strong constraints on the relative contribution of different ph…
From Discs to Bulges: effect of mergers on the morphology of galaxies
Rahul Kannan, Andrea V. Maccio', Fabio Fontanot +3
We study the effect of mergers on the morphology of galaxies by means of the simulated merger tree approach first proposed by Moster et al. This method combines N-body cosmological…
Star formation in mergers with cosmologically motivated initial conditions
Wouter Karman, Andrea V. Maccio, Rahul Kannan +2
We use semi-analytic models and cosmological merger trees to provide the initial conditions for multi-merger numerical hydrodynamic simulations, and exploit these simulations to ex…
Galaxy Formation with Local Photoionization Feedback -II. Effect of X-Ray Emission from Binaries and Hot Gas
Rahul Kannan, Mark Vogelsberger, Greg S. Stinson +4
We study how X-rays from stellar binary systems and the hot intracluster medium (ICM) affect the radiative cooling rates of gas in galaxies. Our study uses a novel implementation o…
