Analysis of Star Formation in Galaxy-like Objects
Patricia B. Tissera
Using cosmological hydrodynamical simulations, we investigate the effects of hierarchical aggregation on the triggering of star formation in galactic-like objects. We include a sim…
Dynamical properties of the conformally coupled flat FRW model
M. A. Castagnino H. Giacomini, L. Lara
In this paper we study the dynamical behaviour of a simple cosmological model defined by a spatially flat Robertson-Walker geometry, conformally coupled with a massive scalar field…
Pragmatic approach to gravitational radiation reaction in binary black holes
C. O. Lousto
We study the relativistic orbit of binary black holes in systems with small mass ratio. The trajectory of the smaller object (another black hole or a neutron star), represented as…
Simultaneous Observations of GRS 1758-258 in 1997 by VLA, IRAM, SEST, RXTE and OSSE: Spectroscopy and Timing
D. Lin, I. A. Smith, E. P. Liang +6
We report the results of our multi-wavelength observations of GRS 1758-258 made in August 1997. The energy bands include radio, millimeter, X-ray, and gamma-ray. The observations e…
Perturbative evolution of nonlinear initial data for binary black holes: Zerilli vs. Teukolsky
C. O. Lousto
We consider the problem of evolving nonlinear initial data in the close limit regime. Metric and curvature perturbations of nonrotating black holes are equivalent to first perturba…
Mergers and star formation in SPH cosmological simulations
Patricia B. Tissera
The star formation rate history of galactic objects in hydrodynamical cosmological simulations are analyzed in relation to their merger histories. The findings suggest that massive…
Scaling law for the heating of solar coronal loops
Pablo Dmitruk, Daniel Gomez
We report preliminary results from a series of numerical simulations of the reduced magnetohydrodynamic equations, used to describe the dynamics of magnetic loops in active regions…
Hydrodynamic transport functions from quantum kinetic theory
E. Calzetta, B. L. Hu, S. Ramsey
Starting from the quantum kinetic field theory [E. Calzetta and B. L. Hu, Phys. Rev. D37, 2878 (1988)] constructed from the closed-time-path (CTP), two-particle-irreducible (2PI) e…
Interacting strings on AdS_3
Gastón Giribet, Carmen Núñez
We consider string theory on AdS_3 in terms of the Wakimoto free field representation. The scattering amplitudes for N unitary tachyons are analysed in the factorization limit and…
ISO Images of Starbursts and Active Galaxies
I. F. Mirabel, O. Laurent
We present some highlights from the mid-infrared (5-16 micron) images of mergers of massive galaxies obtained with the Infrared Space Observatory (ISO). We have observed: 1) ultral…
Plasma and Warm Dust in the Collisional Ring Galaxy VIIZw466 from VLA and ISO Observations
P. N. Appleton, V. Charmandaris, C. Horellou +3
We present the first mid-infrared (Mid-IR) (m) and radio continuum (20,~6 and 3.6 cm) observations of the star-forming collisional ring galaxy VII Zw 466 and its…
Study of the interacting system NGC 6845
Irapuan Rodrigues, Horacio Dottori, Elias Brinks +1
We present optical spectroscopy, B, V, R and I CCD photometry and VLA neutral hydrogen observations of the interacting quartet NGC 6845, also know as Klemola 30. NGC 6845 A, the do…
Feeding the central engine in giant radio galaxies
I. F. Mirabel, O. Laurent
Giant radio galaxies are thought to be massive ellipticals powered by accretion of interstellar matter onto a supermassive black hole. Interactions with gas rich galaxies may provi…
Stochastic dynamics of correlations in quantum field theory: From Schwinger-Dyson to Boltzmann-Langevin equation
Esteban Calzetta, Bei Lok Hu
The aim of this paper is two-fold: in probing the statistical mechanical properties of interacting quantum fields, and in providing a field theoretical justification for a stochast…
Sources of Relativistic Jets in the Galaxy
I. Felix Mirabel, Luis F. Rodriguez
Black holes of stellar mass and neutron stars in binary systems are first detected as hard X-ray sources using high-energy space telescopes. Relativistic jets in some of these comp…
