A gravitational-wave standard siren measurement of the Hubble constant
B. P. Abbott, R. Abbott, T. D. Abbott +1308
The detection of GW170817 in both gravitational waves and electromagnetic waves heralds the age of gravitational-wave multi-messenger astronomy. On 17 August 2017 the Advanced LIGO…
Low X-Ray Luminosity Galaxy Clusters: Main goals, sample selection, photometric and spectroscopic observations
J. L. Nilo Castellón, M. V. Alonso, D. García Lambas +10
We present the study of nineteen low X-ray luminosity galaxy clusters (L 0.5--45 erg s), selected from the ROSAT Position Sensitive Proportional…
On the relation between Seyfert 2 accretion rate and environment at z < 0.1
Georgina V. Coldwell, Sebastian Gurovich, Jorge Diaz Tello +2
We analyse different properties of the small scale environment of Seyfert 2 for two samples selected according to the accretion rate parameter, R, from the DR7-SDSS survey. We comp…
The Angular Clustering of WISE-Selected AGN: Different Haloes for Obscured and Unobscured AGN
E. Donoso, Lin Yan, D. Stern +1
We calculate the angular correlation function for a sample of 170,000 AGN extracted from the Wide-field Infrared Survey Explorer (WISE) catalog, selected to have red mid-IR colors…
Galaxy triplets in Sloan Digital Sky Survey Data Release 7: II. A connection with compact groups?
Fernanda Duplancic, Ana Laura O'Mill, Diego G. Lambas +2
We analyse a sample of 71 triplets of luminous galaxies derived from the work of O'Mill et al. (2012). We compare the properties of triplets and their members with those of control…
Studying the kinematics of the giant star-forming region 30 Doradus. I. The data
S. Torres-Flores, R. Barbá, J. Maíz Apellániz +4
We present high-quality VLT-FLAMES optical spectroscopy of the nebular gas in the giant star-forming region 30 Doradus. In this paper, the first of a series, we introduce our obser…
Effect of bars in AGN host galaxies and black hole activity
Sol Alonso, Georgina Coldwell, Diego Garcia Lambas
With the aim of assessing the effects of bars on active galactic nuclei (AGN), we present an analysis of host characteristics and nuclear activity of AGN galaxies with and without…
A sample of Seyfert-2 galaxies with ultra-luminous galaxy-wide NLRs -- Quasar light echos?
Mischa Schirmer, Ruben Diaz, Karianne Holhjem +2
We report the discovery of Seyfert-2 galaxies in SDSS-DR8 with galaxy-wide, ultra-luminous narrow-line regions (NLRs) at redshifts z=0.2-0.6. With a space density of 4.4 per cubic…
Mid-Infrared Selection of Active Galactic Nuclei with the Wide-Field Infrared Survey Explorer. II. Properties of WISE-Selected Active Galactic Nuclei in the NDWFS Boötes Field
Roberto J. Assef, Daniel Stern, Christopher S. Kochanek +11
Stern et al.(2012) presented a study of WISE selection of AGN in the 2 deg^2 COSMOS field, finding that a simple criterion W1-W2>=0.8 provides a highly reliable and complete AGN sa…
Unveiling the new generation of stars in NGC 604 with Gemini-NIRI
Cecilia Farina, Guillermo L. Bosch, Rodolfo H. Barba
We present a near infrared study focused on the detection and characterization of the youngest stellar component of the NGC 604 giant star-forming region, in the Triangulum galaxy…
Galaxy interactions II: High density environments
Sol Alonso, Valeria Mesa, Nelson Padilla +1
With the aim to assess the role of dense environments in galaxy interactions, properties we present an analysis of close galaxy pairs in groups and clusters, obtained from the Sloa…
Galaxy interactions I: Major and minor mergers
Diego G. Lambas, Sol Alonso, Valeria Mesa +1
We study galaxy pair samples selected from the Sloan Digital Sky Survey (SDSS-DR7) and we perform an analysis of minor and major mergers with the aim of investigating the dependenc…
Metallicity of high stellar mass galaxies with signs of merger events
M. S. Alonso, L. Michel-Dansac, D. G. Lambas
We focus on an analysis of galaxies of high stellar mass and low metallicity. We cross-correlated the Millenium Galaxy Catalogue (MGC) and the Sloan Digital Sky Survey (SDSS) galax…
