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…
Precision abundance analysis of bright HII galaxies
Guillermo F. Hagele, Angeles I. Diaz, Elena Terlevich +3
We present high signal-to-noise spectrophotometric observations of seven luminous HII galaxies. The observations have been made with the use of a double-arm spectrograph which prov…
Kinematics of gas and stars in the circumnuclear starforming ring of NGC 3351
Guillermo F. Hagele, Angeles I. Diaz, Monica V. Cardaci +2
We have measured gas and stellar velocity dispersions in 5 circumnuclear starforming regions (CNSFRs) and the nucleus of the barred spiral galaxy NGC 3351. The stellar dispersions…
An X-ray look at the Seyfert 1 Galaxy Mrk 590: XMM-Newton and Chandra reveal complexity in circumnuclear gas
A. L. Longinotti, S. Bianchi, M. Santos-Lleo +4
This paper reports on a partially simultaneous observation of the bright Seyfert 1 Galaxy Mrk590, performed by XMM-Newton and Chandra. The long exposure (~100 ks) allows to investi…
