Rotation curves and dynamical masses of MaNGA barred galaxies
Eduardo O. Schmidt, Damián Mast, Gaia Gaspar +1
In this paper we analyse a sample of 46 barred galaxies of MaNGA. Our goal is to investigate the stellar kinematics of these galaxies and obtain their rotation curves. Additionally…
Catalogue of central stars of planetary nebulae: Expanded edition
W. A. Weidmann, M. B. Mari, E. O. Schmidt +7
Planetary nebulae represent a potential late stage of stellar evolution, however the central stars (CSPNe) are relatively faint and therefore pertinent information is merely availa…
Towards an improvement in the spectral description of central stars of planetary nebulae
W. Weidmann, R. Gamen, D. Mast +7
Context. There are more than 3000 known Galactic planetary nebulae (PNe), but only 492 central stars of Galactic planetary nebulae (CSPN) have known spectral types. It is vital to…
Asymmetric emission of the [OIII]5007 profile in narrow-line Seyfert 1 galaxies
Eduardo O. Schmidt, Gabriel A. Oio, Diego Ferreiro +2
Many active galactic nuclei (AGN) and particularly narrow-line Seyfert 1 (NLS1) galaxies, usually exhibit blueshifts and blue wings in several emission lines, which are mainly asso…
The interstellar medium and the massive stellar content toward the SNR G18.1-0.1 and neighboring HII regions
S. Paron, W. Weidmann, M. E. Ortega +2
We perform a multiwavelength study toward the SNR G18.1-0.1 and nearby several HII regions (infrared dust bubbles N21 and N22, and the HII regions G018.149-00.283 and G18.197-00.18…
Near-infrared photometry of Galactic planetary nebulae with the VVV Survey
W. A. Weidmann, R. Gamen, P. A. M. van Hoof +3
Planetary nebulae (PNe) are powerful tracers of evolved stellar populations. Among the 3000 known PNe in the Galaxy, about 600 are located within the 520 square-degree area covered…
VVV DR1: The First Data Release of the Milky Way Bulge and Southern Plane from the Near-Infrared ESO Public Survey VISTA Variables in the Via Lactea
R. K. Saito, M. Hempel, D. Minniti +107
The ESO Public Survey VISTA Variables in the Via Lactea (VVV) started in 2010. VVV targets 562 sq. deg in the Galactic bulge and an adjacent plane region and is expected to run for…
The Ap 2-1 nebula and the surrounding molecular cloud G35.2-0.74: an active star forming region
Sergio Paron, Walter Weidmann
Using data from large-scale surveys: 2MASS, GLIMPSE, MIPSGAL, VGPS, GRS, and IPHAS, we performed a multiwavelength study of the ISM in a region of about 20' x 20' towards the molec…
