The MaNGA Low-mass disks HUnt for CO (MaLHUCO) Survey
M. Grossi, E. Corbelli, D. R. Gonçalves +1
We present James Clerk Maxwell Telescope (JCMT) observations of the CO(J = 2-1) emission of 42 low-mass, star-forming disk galaxies of morphological type Scd or later from t…
The Local Group Symbiotic Star Population and its Weak Relation with Type Ia Supernovae
M. Laversveiler, D. R. Gonçalves
Here we study the symbiotic stars (SySt) population and its relation with type Ia supernovae (SNe Ia) in the galaxies of the Local Group. SySt are low- and/or intermediate-mass evo…
Inverted metallicity gradients in two Virgo cluster star-forming dwarf galaxies: evidence of recent merging?
M. Grossi, R. García-Benito, A. Cortesi +5
We present integral field spectroscopy observations of two star-forming dwarf galaxies in the Virgo cluster (VCC135 and VCC324) obtained with PMAS/PPak at the Calar Alto 3.5 meter…
J-PLUS: Tools to identify compact planetary nebulae in the Javalambre and southern photometric local universe surveys
L. A. Gutiérrez-Soto, D. R. Gonçalves, S. Akras +28
From the approximately 3,500 planetary nebulae (PNe) discovered in our Galaxy, only 14 are known to be members of the Galactic halo. Nevertheless, a systematic search for hal…
H in low-ionization structures of planetary nebulae
Stavros Akras, Denise R. Gonçalves, Gerardo Ramos-Larios
We report the detection of near-IR H emission from the low-ionization structures (knots) in two planetary nebulae. The deepest ever, high-angular resolution H 1-0 S(1) at 2…
Low-ionization structures in planetary nebulae - I: physical, kinematic and excitation properties
Stavros Akras, Denise R. Gonçalves
Though the small-scale, low-ionization knots, filaments and jets (LISs) of planetary nebulae (PNe) are known for ~30yr, some of their observational properties are not well establis…
When Shape Matters: correcting the ICFs to derive the chemical abundances of bipolar and elliptical PNe
D. R. Goncalves, R. Wesson, C. Morisset +2
The extraction of chemical abundances of ionised nebulae from a limited spectral range is usually hampered by the lack of emission lines corresponding to certain ionic stages. So f…
