We present two-dimensional Fabry-Perot observations of emission-line distribution and kinematics in nearly spiral galaxies. We have developed and demonstrated...

We have analyzed the effects of gas on the disk-halo evolution in barred galaxies using N-body/SPH simulations. Our main focus has been the angular momentum (J)...

The Sb galaxy NGC 4736 has a well observed ring of bright HII regions just outside its bulge, at some 1.3 kpc from the nucleus, with an apparent expansion...

Understanding how gas flows into galactic centers, fuels the AGN and in turn is expelled back through feedback processes is of great importance to appreciate...

Gas flows into the centres of galaxies form an important ingredient to the formation, growth and evolution of galaxies. The process of gas falling into the...

In the first part of this article we show how observations of the chemical evolution of the Galaxy: G- and K-dwarf numbers as functions of metallicity, and...

We have used the collisional broadening of neutral neon lines to determine the gas temperature of a microwave discharge at atmospheric pressure. The gas...

We combine 12CO J = 3 - 2 for 155 nearby galaxies, obtained as part of the James Clerk Maxwell Telescope (JCMT) Nearby Galaxies Legacy Survey (NGLS), with star...

Recently, mid-infrared (MIR) interferometry and single-dish high angular resolution imaging has revealed the presence of dust in the polar regions of nearby...
