Optical and mid-infrared line emission in nearby Seyfert galaxies
A. Feltre, C. Gruppioni, L. Marchetti +24
Line ratio diagnostics provide valuable clues on the source of ionizing radiation in galaxies with intense black hole accretion and starbursting events, such as local Seyfert or ga…
Stellar populations of a sample of far-IR AGN and non-AGN green valley galaxies
Antoine Mahoro, Mirjana Pović, Petri Väisänen +2
We present a study on the stellar populations and stellar ages of sub-sample of far-infrared AGN and non-AGN green valley analysed in Mahoro et al. (2017,2019) at 0.6 < z < 1.0 usi…
A Peculiar Type~II QSO Identified via Broad-band Detection of Extreme Nebular Line Emission
Yu-Heng Lin, Claudia Scarlata, Matthew Hayes +5
We present S82-20, an unusual redshift 3 object identified in SDSS-Stripe 82 broad-band images. The rest-frame ultraviolet spectrum of S82-20 shows emission lines from hig…
Extragalactic background Light: a measurement at 400 nm using dark cloud shadow II. Spectroscopic separation of dark cloud's light, and results
K. Mattila, P. Väisänen, K. Lehtinen +2
In a project aimed at measuring the optical Extragalactic Background Light (EBL) we are using the shadow of a dark cloud.We have performed, with the ESO VLT/FORS, spectrophotometry…
Star formation and AGN activity in a sample of local Luminous Infrared Galaxies through multi-wavelength characterization
Rubén Herrero-Illana, Miguel Á. Pérez-Torres, Zara Randriamanakoto +8
Nuclear starbursts and AGN activity are the main heating processes in luminous infrared galaxies (LIRGs) and their relationship is fundamental to understand galaxy evolution. In th…
The empty ring galaxy ESO 474 - G040
Noah Brosch, Petri Vaisanen, Alexei Kniazev +1
We describe observations of the apparently empty ring galaxy ESO 474-G040 obtained with the Southern African Large Telescope (SALT). The observations, consisting of imaging, long-s…
