SIGNALS: I. Survey Description
L. Rousseau-Nepton, R. P. Martin, C. Robert +60
SIGNALS, the Star formation, Ionized Gas, and Nebular Abundances Legacy Survey, is a large observing program designed to investigate massive star formation and HII regions in a sam…
Diffuse ionized gas and its effects on nebular metallicity estimates of star-forming galaxies
N. Vale Asari, G. S. Couto, R. Cid Fernandes +5
We investigate the impact of the diffuse ionized gas (DIG) on abundance determinations in star-forming (SF) galaxies. The DIG is characterised using the H equivalent width ($W_{…
Ionization correction factors for ionized nebulae
Gloria Delgado-Inglada, Alexia Medina-Amayo, Grażyna Stasińska
In this paper we discuss the calculation of chemical abundances in planetary nebulae and H II regions through ionization correction factors (ICFs). We review the first ICFs propose…
Why do many early-type galaxies lack emission lines? I. Fossil clues
F. Herpich, G. Stasińska, A. Mateus +2
Early-type retired galaxies (RGs, i.e. galaxies which no longer form stars) can be divided into two classes: those with no emission lines, here dubbed lineless RGs, and those with…
What distinguishes the host galaxies of radio-loud and radio-quiet AGNs?
D. Kozieł-Wierzbowska, N. Vale Asari, G. Stasińska +3
We compare the optical properties of the host galaxies of radio-quiet (RQ) and radio-loud (RL) Type 2 active galactic nuclei (AGNs) to infer whether the jet production efficiency d…
A quick start guide to BOND: Bayesian Oxygen and Nitrogen abundance Determinations in H II regions using strong and semistrong lines
N. Vale Asari, G. Stasińska, C. Morisset +1
We present a quick-start guide to BOND, a statistical method to derive oxygen and nitrogen abundances in H II regions. BOND compares a set of carefully selected strong and semistro…
The many faces of LINER-like galaxies: a WISE view
F. R. Herpich, A. Mateus, G. Stasińska +2
We use the SDSS and WISE surveys to investigate the real nature of galaxies defined as LINERs in the BPT diagram. After establishing a mid-infrared colour W2-W3 = 2.5 as the optima…
Oxygen enrichment in carbon-rich planetary nebulae
Gloria Delgado-Inglada, Mónica Rodríguez, Manuel Peimbert +2
We study the relation between the chemical composition and the type of dust present in a group of 20 Galactic planetary nebulae (PNe) that have high quality optical and infrared sp…
Retired galaxies: not to be forgotten in the quest of the star formation -- AGN connection
G. Stasińska, M. V. Costa Duarte, N. Vale Asari +2
We propose a fresh look at the Main Galaxy Sample of the Sloan Digital Sky Survey by packing the galaxies in stellar mass and redshift bins. We show how important it is to consider…
Constraining jet production scenarios by studies of Narrow-Line-Radio-Galaxies
Marek Sikora, Grażyna Stasińska, Dorota Kozieł-Wierzbowska +2
We study a large sample of narrow-line radio galaxies (NLRGs) with extended radio structures. Using 1.4 GHz radio luminosities, , narrow optical emission line luminosities…
FRII radio galaxies in the SDSS: Observational facts
Dorota Kozieł-Wierzbowska, Grażyna Stasińska
Starting from the Cambridge Catalogues of radio sources, we have created a sample of 401 FRII radio sources that have counterparts in the main galaxy sample of the 7th Data release…
The chemical composition of the Orion star-forming region: II. Stars, gas, and dust: the abundance discrepancy conundrum
S. Simón-Díaz, G. Stasińska
We re-examine the recombination/collisional emission line (RL/CEL) nebular abundance discrepancy problem in the light of recent high-quality abundance determinations in young stars…
The chemical composition of the Orion star forming region: stars, gas and dust
S. Simón-Díaz, M. F. Nieva, N. Przybilla +1
We present a summary of main results from the studies performed in the series of papers "The chemical composition of the Orion star forming region". We reinvestigate the chemical c…
Distinguishing post-AGB impostors in a sample of pre-main sequence stars
Rodrigo G. Vieira, Jane Gregorio-Hetem, Annibal Hetem +2
A sample of 27 sources, catalogued as pre-main sequence stars by the Pico dos Dias Survey (PDS), is analyzed to investigate a possible contamination by post-AGB stars. The far-infr…
