Direct Abundance Maps and Radial Metallicity Gradients of two Galaxies at z~4-5 in the GARDEN Survey
L. Stanghellini, S. A. Kassin, C. Pacifici +26
We investigate galaxies in the GARDEN (Galaxies at All Redshifts Deciphered and Explained with the NIRSpec MSA) survey that exhibit auroral emission lines, enabling spatially resol…
GTC/OSIRIS Deep Spectroscopy of Galactic Compact Planetary Nebulae: PNG048.5+04.2 and PNG068.7+14.8
Haomiao Huang, Xuan Fang, Letizia Stanghellini +5
We report deep long-slit spectroscopy of two Galactic compact planetary nebulae (PNe), PNG048.5+04.2 and PNG068.7+14.8, obtained using the 10.4m Gran Telescopio Canarias (GTC). The…
The planetary nebula NGC 3132 revisited: high definition 3D photoionization model
H. Monteiro, C. Mendes de Oliveira, P. Amram +6
We present a detailed 3D photoionization model of the planetary nebula NGC 3132, constrained by the latest observations. Using the MOCASSIN code, the model incorporates integrated…
Planetary Nebulae of the Large Magellanic Cloud II: the connection with the progenitors' properties
P. Ventura, S. Tosi, D. A. GarcÃa-Hernández +6
The study of planetary nebulae (PNe) offers the opportunity of evaluating the efficiency of the dust production mechanism during the very late asymptotic giant branch (AGB) phases.…
