We study the pitch angles of spiral arms and the frequency and dimensions of inner and outer rings as a function of disk parameters and the amplitude of non...

In this brief note we remark that the four spatially resolved relativistic radio jets among the 14 dynamically confirmed black hole x-ray novae are all in...

It is very common in astrophysics that certain relevant parameters of the objects studied cannot be obtained directly from observations, but require numerical...

We report on our year-long (2009-'10) campaign with the Chandra X-ray observatory, to capture the transient X-ray binary (XRB) population in the nearby...

Phoenix spectra of C_2, CN and CO lines will provide oxygen isotopic abundance ratios (^16O/^17O/^18O) and CNO abundances for cool R Coronae Borealis (RCB)...

It is widely accepted that starbursts can dramatically affect their host galaxies via feedback-driven outflows, especially for gas-rich dwarfs with shallow...

The Cocoon nebula is an apparently spherical Galactic HII region ionized by a single star (BD+46 3474). This nebula seems to be appropriate to investigate the...

A good alternative to traditional methods of passing on astronomical concepts is to use a 'collateral' story that catches the public's attention. It may also...
