New Results on R Aquarii
D. R. Goncalves, A. Mampaso, S. Navarro +1
The first results on new optical data for R Aquarii (based on observations obtained with the 2.5m INT, the 2.5m NOT and the 3.5m NTT) are presented. The morphology and kinematics o…
The Physical Parameters and Excitation of Jets and Knots in PNe
D. R. Goncalves, A. Mampaso, R. M. L. Corradi +1
We are carrying out a study of the physical parameters and excitation of low-ionization structures (LIS) in planetary nebulae (PNe). Since the optical morphology and kinematics of…
Characterizing Low-Ionization Structures in PNe
Denise R. Goncalves
Fifty five planetary nebulae containing micro-structures of low-ionization (LIS) are analyzed in this review in terms of LIS morphology, kinematics, and physical and excitation pro…
Enigmatic low-velocity jet-like features in planetary nebulae
Denise R. Goncalves, Romano L. M. Corradi, Antonio Mampaso
We are developing a project aimed at studying the physical properties, origin and evolution of low-ionization structures in planetary nebulae. Within this project we have identifie…
Magnetic Fields on the Dynamics of the ICM
D. R. Goncalves, A. C. S. Friaca
Could the discrepancies found in the determination of mass in clusters of galaxies, from gravitational lensing data and from X-rays observations, be consequence of the standard des…
Alfven heating in optical filaments in cooling flows
A. C. S. Friaca, D. R. Goncalves, L. C. Jafelice +2
One of the major problems concerning cooling flows is the nature of the mechanism powering the emission lines of the optical filaments seen in the inner regions of cooling flows. I…
