Characterizing chemical abundance ratios in extremely metal-poor star-forming galaxies in DESI EDR
I. A. Zinchenko, M. Sobolenko, J. M. Vilchez +1
We present a search for galaxies in the local Universe with extremely low oxygen abundance, that is, more than 25 times lower than solar, which corresponds to 12 + log(O/H) < 7.3.…
Different behaviour of the gas-phase and stellar metallicity in the central part of MaNGA galaxies
I. A. Zinchenko, J. M. Vilchez
We quantified the disparity between gas-phase and stellar metallicity in a large galaxy sample obtained from the MaNGA DR17 survey. We found that the gas metallicity is on average…
The miniJPAS Survey: The radial distribution of star formation rates in faint X-ray active galactic nuclei
Nischal Acharya, Silvia Bonoli, Mara Salvato +35
We study the impact of black hole nuclear activity on both the global and radial star formation rate (SFR) profiles in X-ray-selected active galactic nuclei (AGN) in the field of m…
On the Contribution of Very Massive Stars to the Sulfur Abundance in Star-Forming Galaxies: the Role of PISN
S. Goswami, J. M. Vilchez, B. Perez-Diaz +3
Recent work presented increasing evidence of high, non-constant S/O abundance ratios observed in star-forming metal-poor galaxies, showing deviations from the constant canonical S/…
Multiwavelength exploration of Extreme Emission Line Galaxies detected in miniJPAS survey
Iris Breda, Stergios Amarantidis, José M. Vilchez +24
Extreme Emission Line Galaxies (EELGs) stand as remarkable objects due to their extremely metal poor environment and intense star formation. Considered as local analogues of high-r…
