The growth of galaxies in cosmological simulations of structure formation
Chigurupati Murali, Neal Katz, Lars Hernquist +2
We use hydrodynamic simulations to examine how the baryonic components of galaxies are assembled, focusing on the relative importance of mergers and smooth accretion in the formati…
Constraints on Stirring and Dissipation of MHD Turbulence in Molecular Clouds
Shantanu Basu, Chigurupati Murali
We discuss constraints on the rates of stirring and dissipation of MHD turbulence in molecular clouds. Recent MHD simulations suggest that turbulence in clouds decays rapidly, thus…
The Magellanic Stream and the density of coronal gas in the Galactic halo
C. Murali
The properties of the Magellanic Stream constrain the density of coronal gas in the distant Galactic halo. We show that motion through ambient gas can strongly heat Stream clouds,…
Determining the galactic mass distribution using tidal streams from globular clusters
C. Murali, J. Dubinski
We discuss how to use tidal streams from globular clusters to measure the mass distribution of the Milky Way. Recent proper motion determinations for globular clusters from plate m…
Constraints on the mass and abundance of black holes in the Galactic halo: the high mass limit
C. Murali, P. Arras, I. Wasserman
We establish constraints on the mass and abundance of black holes in the Galactic halo by determining their impact on globular clusters which are conventionally considered to be li…
Transmission and amplification of disturbances by massive halos
C. Murali
We study how massive halos respond to perturbations. Through numerical solution of the coupled linearized Boltzmann-Poisson equations, we find that halos transmit and amplify distu…
Gamma Ray Bursts from Stellar Collisions
Brad M. S. Hansen, Chigurupati Murali
We propose that the cosmological gamma ray bursts arise from the collapse of neutron stars to black holes triggered by collisions or mergers with main sequence stars. This scenario…
Linear response of galactic halos to adiabatic gravitational perturbations
Chigurupati Murali, Scott Tremaine
We determine the response of a self-similar isothermal stellar system to small adiabatic gravitational perturbations. For odd spherical harmonics, the response is identical to the…
Evolution of Galactic Globular Clusters
Chigurupati Murali, Martin D. Weinberg
We study the dynamical evolution of disk and halo globular clusters in the Milky Way using a series of Fokker-Planck calculations combined with parametric statistical models. Our s…
The Effect of the Galactic Spheroid on Globular Cluster Evolution
C. Murali, M. D. Weinberg
We study the combined effects of relaxation, tidal heating and binary heating on globular cluster evolution, exploring the physical consequences of external effects and examining e…
Globular Cluster Evolution in M87 and Fundamental Plane Ellipticals
C. Murali, M. D. Weinberg
The globular cluster population in M87 has decreased measurably through dynamical evolution caused by relaxation, binary heating and time-dependent tidal perturbation. For fundamen…
