The interplay between star formation and the nuclear environment of our Galaxy: deep X-ray observations of the Galactic centre Arches and Quintuplet clusters
n star formation the nuclear environment
2014/12/24
The Galactic centre (GC) provides a unique laboratory for a detailed examination of the interplay between massive star formation and the nuclear environment of our Galaxy. Here, we present a 100-ks Ch...
High-Resolution Imaging of Warm and Dense Molecular Gas in the Nuclear Region of the Luminous Infrared Galaxy NGC 6240
formation interaction,
2014/12/23
We present ~2'' resolution CO (3-2), HCO+(4-3), and 880 μm continuum images of the luminous infrared galaxy NGC 6240 obtained at the Submillimeter Array. We find that the spatially resolved CO (3-2), ...
Nuclear structure in strong magnetic fields: nuclei in the crust of a magnetar
Nuclear structure strong magnetic fields: nuclei crust magnetar
2011/10/14
Covariant density functional theory is used to study the effect of strong magnetic fields, up to the limit predicted for neutron stars (for magnetars $B \approx10^{18}$G), on nuclear structure. All ne...
Nuclear Rings in Galaxies---A Kinematic Perspective
Nuclear Rings Galaxies---A Kinematic Perspective
2011/10/19
We combine DensePak integral field unit and TAURUS Fabry-Perot observations of 13 nuclear rings to show an interconnection between the kinematic properties of the rings and their resonant origin. The ...

Astroparticle physics – cosmic rays – ISM: supernova remnants
2011/10/13
The supernova remnant Cassiopeia A is a prime candidate for accelerating cosmic ray protons and ions. Gamma rays have been observed at GeV and TeV energies, which indicates hadronic interactions, but ...
Standard Big-Bang Nucleosynthesis up to CNO with an improved extended nuclear network
Big-Bang Nucleosynthesis improved extended nuclear network
2011/9/28
Primordial or Big Bang nucleosynthesis (BBN) is one of the three strong evidences for the Big- Bang model together with the expansion of the Universe and the Cosmic Microwave Background radiation. In ...
