GAMER with out-of-core computation
GAMER is a GPU-accelerated Adaptive-MEsh-Refinement code for astrophysical simulations. In this work, two further extensions of the code are reported. First, we have implemented the MUSCL-Hancock method with the Roe's Riemann solver for the hydrodynamic evolution, by which the accuracy, overall p...Tags: gpu, instrumentation, methods

Study of electromagnetic backgrounds in the 25-300 MHz frequency band at the South Pole
Extensive air showers are detectable by radio signals with a radio surface detector. A promising theory of the dominant emission process is the coherent synchrotron radiation emitted by e+ e- shower particles in the Earth's magnetic field (geosynchrotron effect). A radio air shower detector can e...Tags: instrumentation, methods, arxiv

PyMorph: Automated Galaxy Structural Parameter Estimation using Python
We present a new software pipeline -- PyMorph -- for automated estimation of structural parameters of galaxies. Both parametric fits through a two dimensional bulge disk decomposition as well as structural parameter measurements like concentration, asymmetry etc. are supported. The pipeline is de...Tags: python, galaxies, mnras, arxiv, extragalactic astrophysics, methods
