Chemical enrichment in LINERs from MaNGA. I. Tracing Oxygen and Nitrogen Nuclear Abundances in LINERs with Varied Ionizing Sources
Borja Pérez-Díaz, Enrique Pérez-Montero, Igor A. Zinchenko +1
The chemical enrichment in low-ionization nuclear emission-line regions (LINERs) is still an issue with spatial resolution spectroscopic data due to the lack of studies and the unc…
Semi-empirical calibration of the oxygen abundance for LINER galaxies based on SDSS-IV MaNGA -- The case for strong and weak AGN
C. B. Oliveira, O. L. Dors, I. A. Zinchenko +5
In this paper, we present a semi-empirical calibration between the oxygen abundance and the emission-line ratio for Low Ionization Nuclear Emission Regions (LINERs). This rela…
Euclid preparation. XLIX. Selecting active galactic nuclei using observed colours
Euclid Collaboration, L. Bisigello, M. Massimo +244
Euclid will cover over 14000 with two optical and near-infrared spectro-photometric instruments, and is expected to detect around ten million active galactic nuclei (AGN)…
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…
Euclid preparation. LI. Forecasting the recovery of galaxy physical properties and their relations with template-fitting and machine-learning methods
Euclid Collaboration, A. Enia, M. Bolzonella +260
Euclid will collect an enormous amount of data during the mission's lifetime, observing billions of galaxies in the extragalactic sky. Along with traditional template-fitting metho…
