Gas Cell Development for Infrared Spectra Calibration
NAHUAL is a high-resolution near-infrared echelle spectrograph of high stability on preliminary phase development for GTC (Gran Telescopio de Canarias). Its...
The interstellar medium of early type galaxies has attracted a great deal of interest ever since Faber & Gallagher (1976) showed that a considerable amount of...
Gas Dynamics and Star Formation in the Grand-Design Spiral NGC 5248
We present a multi-wavelength study of the gas dynamics and star formation in the grand-design spiral galaxy NGC 5248, illustrating how coupled dynamical...
We present two-dimensional Fabry-Perot observations of emission-line distribution and kinematics in nearly spiral galaxies. We have developed and demonstrated...
Gas Feedback and Angular Momentum Redistribution in Barred Galaxies within Dark Matter Halos
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)...
Gas flow, population structure and starburst activity in the central zone of NGC 4736
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...
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...
Gas temperature from line broadening in a neon microwave plasma at atmospheric pressure
We have used the collisional broadening of neutral neon lines to determine the gas temperature of a microwave discharge at atmospheric pressure. The gas...
