WALLABY pilot survey: Blinded by the light -- discovery of a fourth member in the ESO 179-013 system
Rayssa Guimarães Silva, Marco Grossi, Denise R. Gonçalves +12
We present new ASKAP/WALLABY HI observations of the nearby dwarf galaxy system ESO 179-013 (Kathryn's Wheel), the nearest known collisional ring galaxy, located 10 Mpc away in the…
J-PLUS: The planetary nebula population of M 33
Giovanna Liberato, Denise R. Gonçalves, Arianna Cortesi +21
In this pilot study, we investigate the PN population in M~33, a nearby spiral galaxy (~kpc), using data from the DR3 of the Javalambre-Photometric Local Universe Surve…
The Local Group Symbiotic Star Population and its Tenuous Link with Type Ia Supernovae
Marco Laversveiler, Denise R. Gonçalves, Helio J. Rocha-Pinto +1
Binary stars are gravitationally bound stellar systems where the evolution of each component can significantly influence the evolution of its companion and the system as a whole. I…
Stellar atmospheric parameters and chemical abundances of about 5 million stars from S-PLUS multi-band photometry
C. E. Ferreira Lopes, L. A. Gutiérrez-Soto, V. S. Ferreira Alberice +30
Context. Spectroscopic surveys like APOGEE, GALAH, and LAMOST have significantly advanced our understanding of the Milky Way by providing extensive stellar parameters and chemical…
Photometric candidate selection and spectroscopic confirmation of new PNe and SySts in the Galactic plane
Giovanna Liberato, Denise R. Gonçalves, Luis A. Gutiérrez-Soto +1
About 3,500 planetary nebulae (PNe) are currently known in the Milky Way, which shows a great discrepancy with the expected number for these objects, regardless of the reference us…
Low-ionization structures in planetary nebulae -- III. The statistical analysis of physico-chemical parameters and excitation mechanisms
M. Belén Mari, Stavros Akras, Denise R. Gonçalves
Nearly 30 years after the first detailed studies of low-ionization structures (LISs) in planetary nebulae (PNe), we perform a statistical analysis of their physical, chemical and e…
What do planetary nebulae and H II regions reveal about the chemical evolution of nearby dwarf galaxies?
Denise R. Gonçalves
The Local Group contains a great number of dwarf irregulars and spheroidals, for which the spectroscopy of individual stars can be obtained. Thus, the chemical evolution of these g…
J-PLUS: The Javalambre Photometric Local Universe Survey
A. J. Cenarro, M. Moles, D. Cristóbal-Hornillos +119
J-PLUS is an ongoing 12-band photometric optical survey, observing thousands of square degrees of the Northern hemisphere from the dedicated JAST/T80 telescope at the Observatorio…
