Group Scaling Relations From a Cosmological Hydrodynamic Simulation: No Pre-heating Required?
pre-heating entropy fl oors
2014/12/26
We investigate the X-ray vs. optical scaling relations of poor groups
to small clusters ( 100−700 km/s) identified in a cosmological hydro-
dynamic simulation of a ΛCDM universe, with cooli...
Hydrodynamic simulation of the cosmological X-ray background
observations large scale structure of Universe
2014/12/26
We use a hydrodynamic simulation of an inflationary cold dark matter model with a cosmological constant to predict properties of the extragalactic X-ray background (XRB). We focus on emission from the...
X-ray scaling relations of galaxy groups in a hydrodynamic cosmological simulation
theory clusters
2014/12/26
We examine the scalings of X-ray luminosity, temperature, and dark matter or galaxy velocity dispersion for galaxy groups in a ΛCDM cosmological simulation, which incorporates gravity, gas dynamics, r...
Star formation and feedback in smoothed particle hydrodynamic simulations - I. Isolated galaxies
star formation supernova feedback
2014/12/24
We present an analysis of star formation and feedback recipes appropriate for galactic smoothed particle hydrodynamics simulations. Using an isolated Milky Way-like galaxy, we constrain these recipes ...
Intergalactic dust extinction in hydrodynamic cosmological simulations
formation intergalactic medium
2014/12/22
Recently Ménard et al. (hereafter MSFR) detected a subtle but systematic change in the mean colour of quasars as a function of their projected separation from foreground galaxies, extending to comovin...
The nature of submillimetre galaxies in cosmological hydrodynamic simulations
star-forming submillimetre galaxies
2014/12/20
We study the nature of rapidly star-forming galaxies at z= 2 in cosmological hydrodynamic simulations, and compare their properties to observations of submillimetre galaxies (SMGs). We identify simula...
Theoretical Support for the Hydrodynamic Mechanism of Pulsar Kicks
High Energy Astrophysical Phenomena (astro-ph.HE) Solar and Stellar Astrophysics (astro-ph.SR) High Energy Physics - Phenomenology (hep-ph)
2010/12/24
The collapse of a massive star's core, followed by a neutrino-driven, asymmetric supernova explosion, can naturally lead to pulsar recoils and neutron star kicks.

A heliospheric hybrid model：hydrodynamic plasma flow and kinetic cosmic ray transport
heliospheric hybrid hydrodynamic plasma flow kinetic cosmic ray transport
2009/5/27
In this paper we present a new five particle species hybrid model for calculating cosmic ray particle transport and acceleration in a dynamic heliospheric environment. In particular the effects of sol...
