The undetectable fraction of core-collapse supernovae in luminous infrared galaxies -- II. GSAOI/GeMS dataset
I. Mäntynen, E. Kankare, S. Mattila +7
Core-collapse supernovae (CCSNe) in luminous infrared galaxies (LIRGs) can have extreme line-of-sight host galaxy dust extinctions, which leads to a large fraction of the events re…
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…
A comparison between SALT/SAAO observations and kilonova models for AT 2017gfo: the first electromagnetic counterpart of a gravitational wave transient - GW170817
David A. H. Buckley, Igor Andreoni, Sudhanshu Barway +13
We report on SALT low resolution optical spectroscopy and optical/IR photometry undertaken with other SAAO telescopes (MASTER-SAAO and IRSF) of the kilonova AT 2017gfo (aka SSS17a)…
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…
