The virus-p exploration of nearby galaxies (venga): radial gas inflow andshock excitation in ngc 1042
(IOP Publishing, 2016)
NGC 1042 is a late-type bulgeless disk galaxy that hosts low-luminosity active galactic nuclei (AGNs) coincident with a massive nuclear star cluster. In this paper, we present the integral field spectroscopy studies of ...
Dissecting galaxy triplets in the Sloan Digital Sky Survey Data Release 10 - I. Stellar populations and emission line analysis
(Wiley Blackwell Publishing, Inc, 2016-04)
We identify isolated galaxy triplets in a volume-limited sample from the Sloan Digital Sky Survey Data Release 10. Our final sample has 80 galaxy systems in the redshift range 0.04 ≤ z ≤ 0.1, brighter than Mr = −20.5 + ...
Occurrence of LINER galaxies within the galaxy group environment
(Oxford University Press, 2017-05)
We study the properties of a sample of 3967 low-ionization nuclear emission-line region (LINER) galaxies selected from SDSS-DR7, with respect to their proximity to galaxy groups. The host galaxies of LINERs have been ...
Chemical abundances of Seyfert 2 AGNs, II: N2 metallicity calibration based on SDSS
(Wiley Blackwell Publishing, Inc, 2020-06)
We present a semi-empirical calibration between the metallicity (Z) of Seyfert 2 active galactic nuclei and the N2 = log([N II]λ6584/H a) emission-line intensity ratio. This calibration was derived through the [OIII]λ5007/[O ...
