Non-relativistic Extended Gravity and its applications across different astrophysical scales
Non-relativistic Extended Gravity applications different astrophysical scales
2012/2/23
Using dimensional analysis techniques we present an extension of Newton's gravitational theory built under the assumption that Milgrom's acceleration constant is a fundamental quantity of nature. The ...
Theory of magnetic reconnection in solar and astrophysical plasmas
Theory magnetic reconnection solar astrophysical plasmas
2012/2/23
Magnetic reconnection is a fundamental process in a plasma that facilitates the release of energy stored in the magnetic field by permitting a change in the magnetic topology. In this article we prese...
Sc III Spectral Properties of Astrophysical Interest
Oscillator strengths lifetimes coupled-cluster method
2011/10/18
Transition properties such as oscillator strengths, transition rates, branching ratios and lifetimes of many low-lying states in the doubly ionized scandium (Sc III) are reported. A relativistic metho...
Far-Infrared to Millimeter Astrophysical Dust Emission. II: Comparison of the Two-Level Systems (TLS) model with Astronomical Data
Far-Infrared Millimeter Astrophysical Dust Emission Comparison model Astronomical Data
2011/10/20
In a previous paper we proposed a new model for the emission by amorphous astronomical dust grains, based on solid-state physics. The model uses a description of the Disordered Charge Distribution (DC...
Open clusters in 2MASS photometry - I. Structural and basic astrophysical parameters
associations general – infrared galaxies – astronomical databases
2011/10/21
The main goal of our project is to obtain a complete picture of individual open clusters from homogeneous data and then search for correlations between their astrophysical parameters. The near-infrare...
Can an astrophysical black hole have a topologically non-trivial event horizon?
astrophysical black hole topologically non-trivial horizon
2011/10/17
In 4-dimensional General Relativity, there are several theorems restricting the topology of the event horizon of a black hole. In the stationary case, black holes must have a spherical horizon, while ...
Nonradial and nonpolytropic astrophysical outflows IX. Modeling T Tauri jets with a low mass-accretion rate
MHD, Stars: pre-main sequence, Stars: winds, outfl ows, Stars: mass-loss, Stars: rotation, ISM
2011/10/8
Context: A large sample of T Tauri stars exhibits optical jets, approximately half of which rotate slowly, only at ten per cent of their breakup velocity. The disk-locking mechanism has been shown to ...
DAMA and CoGeNT without astrophysical uncertainties
DAMA CoGeNT without astrophysical uncertainties
2011/10/18
The CoGeNT collaboration has reported evidence of an annual modulation in its first fifteen months of data. Here we compare the amplitude and phase of this signal to the modulation observed by the DAM...
Surface tension in the cold and dense chiral transition and astrophysical applications
Surface tension old chiral transition astrophysical applications
2011/10/18
The surface tension of cold and dense QCD phase transitions has appeared recently as a key ingredient in different astrophysical scenarios, ranging from core-colapse supernovae explosions to compact s...
Adaptive image ray-tracing for astrophysical simulations
Adaptive image ray-tracing astrophysical simulations
2011/1/11
A technique is presented for producing synthetic images from numerical simulations whereby the image resolution is adapted around prominent features. In so doing, adaptive image ray-tracing (AIR) impr...
Modeling maximum astrophysical gravitational recoil velocities
maximum astrophysical gravitational recoil velocities
2010/11/16
We measure the recoil velocity as a function of spin for equal-mass, highly-spinning black-hole
binaries, with spins in the orbital plane, equal in magnitude and opposite in direction. We con rm that...
Underground searches for dark matter involve a complicated interplay of particle physics, nuclear physics, atomic physics and astrophysics. We attempt to remove the uncertainties associated with astro...
