Dissecting NGC 3132: Tracing the mass-loss history of the southern ring planetary nebula
K. Bouvis, S. Akras, H. Monteiro +7
Central to our understanding of stellar evolution and its impact on processes in our Galaxy and across the Universe is the study of mass loss. While the general framework is well e…
ALMA detection of Masers and Dasars in the Hydrogen Recombination Lines of the Planetary Nebula Mz3
Z. Abraham, P. P. B. Beaklini, I. Aleman +5
The hydrogen recombination lines H30, H40, H42, H50 and H57 and the underlying bremsstrahlung continuum emission were detected with ALMA in the bipolar nebula Mz3. T…
Detection of optical emission from the supernova remnant G7.7-3.7
V. Domček, J. V. Hernández Santisteban, A. Chiotellis +6
We present the first optical study of the supernova remnant (SNR) G7.7-3.7, with the aim of determining its evolutionary phase since it has been suggested to be the remnant of SN 3…
Low-ionization structures in planetary nebulae -- II. Densities, temperatures, abundances and excitation of 6 PNe
M. Belén Mari, Denise R. Gonçalves, Stavros Akras
Here we present the spatially resolved study of six Galactic planetary nebulae (PNe), namely IC 4593, Hen 2-186, Hen 2-429, NGC 3918, NGC 6543 and NGC 6905, from intermediate-resol…
On the discovery of stars, quasars, and galaxies in the Southern Hemisphere with S-PLUS DR2
L. Nakazono, C. Mendes de Oliveira, N. S. T. Hirata +25
This paper provides a catalogue of stars, quasars, and galaxies for the Southern Photometric Local Universe Survey Data Release 2 (S-PLUS DR2) in the Stripe 82 region. We show that…
Exploring the differences of integrated and spatially resolved analysis using integral field unit data: The case of Abell 14
Stavros Akras, Hektor Monteiro, Isabel Aleman +3
We present a new approach to study planetary nebulae using integral field spectroscopy. VLT@VIMOS datacube of the planetary nebula Abell 14 is analysed in three different ways by e…
Characterisation of the Planetary Nebula Tc 1 Based on VLT X-Shooter Observations
Isabel Aleman, Marcelo L. Leal-Ferreira, Jan Cami +11
We present a detailed analysis of deep VLT/X-Shooter observations of the planetary nebula Tc 1. We calculate gas temperature, density, extinction, and abundances for several specie…
