Physical properties of circumnuclear ionising clusters. IV. NGC 1097
Sandra Zamora, Angeles I. Díaz, Asier Castrillo
The circumnuclear star-forming ring of the barred spiral galaxy NGC 1097 provides a unique laboratory to study star formation under extreme conditions. This work aims to derive the…
Physical properties of circumnuclear ionising clusters. III. Kinematics of gas and stars in NGC 7742
S. Zamora, A. I. Díaz, Roberto Terlevich +2
In this third paper of a series, we study the kinematics of the ionised gas and stars, calculating the dynamical masses of the circumnuclear star-forming regions in the ring of of…
Physical properties of circumnuclear ionising clusters. I. NGC 7742
S. Zamora, A. I. Díaz
This work aims to derive the physical properties of the CNSFRs in the ring of the face-on spiral NGC 7742 using IFS observations. We have selected 88 individual ionising clusters t…
Interstellar extinction correction in ionised regions using HeI lines
S. Zamora, Ángeles I. Díaz, Elena Terlevich +1
The logarithmic extinction coefficient, c(H), is usually derived using the H/H ratio for case B recombination and assuming standard values of electron density and temperat…
Kinematics of gas and stars in circumnuclear star-forming regions of early type spirals
Guillermo F. Hagele, Angeles I. Diaz, Monica V. Cardaci +2
(Abbr.) We present high resolution (R~20000) spectra in the blue and the far red of cicumnuclear star-forming regions (CNSFRs) in three early type spirals (NGC3351, NGC2903 and NGC…
The metallicity of circumnuclear star forming regions
A. I. Diaz, E. Terlevich, M. Castellanos +1
We present a spectrophotometric study of circumnuclear star forming regions (CNSFR) in the early type spiral galaxies: NGC 2903, NGC 3351 and NGC 3504, all of them of over solar me…
Spectrophotometry of massive star forming regions with GTC
M. Castellanos, A. I. Diaz, E. Terlevich
In these latest years, the detection of Wolf-Rayet (WR) stars in Giant HII Regions (GHRs) has yielded several questions about our current understanding of massive stars evolution a…
