The CAVITY project. The spatially resolved stellar population properties of galaxies in voids
Ana M. Conrado, Rosa M. González Delgado, Rubén García-Benito +28
The Universe is shaped as a web-like structure, formed by clusters, filaments, and walls that leave large volumes in between named voids. Galaxies in voids have been found to be of…
Stellar mass-metallicity relation throughout the large-scale structure of the Universe: CAVITY mother sample
Jesús Domínguez-Gómez, Isabel Pérez, Tomás Ruiz-Lara +21
Void galaxies are essential for understanding the physical processes that drive galaxy evolution because they are less affected by external factors than galaxies in denser environm…
Galaxies in voids assemble their stars slowly
J. Domínguez-Gómez, I. Pérez, T. Ruiz-Lara +20
Galaxies in the Universe are distributed in a web-like structure characterised by different large-scale environments: dense clusters, elongated filaments, sheetlike walls, and unde…
MIGHTEE-HI: The HI mass-stellar mass relation over the last billion years
Hengxing Pan, Matt J. Jarvis, Mario G. Santos +19
We study the relation over the last billion years using the MIGHTEE-HI sample. We first model the upper envelope of the relation with…
Non-parametric estimation of morphological lopsidedness
Nadine Giese, Thijs van der Hulst, Paolo Serra +1
Asymmetries in the neutral hydrogen gas distribution and kinematics of galaxies are thought to be indicators for both gas accretion and gas removal processes. These are of fundamen…
The environmental dependence of HI in galaxies in the EAGLE simulations
Antonino Marasco, Robert A. Crain, Joop Schaye +4
We use the EAGLE suite of cosmological hydrodynamical simulations to study how the HI content of present-day galaxies depends on their environment. We show that EAGLE reproduces ob…
The EAGLE simulations: atomic hydrogen associated with galaxies
Robert A. Crain, Yannick M. Bahe, Claudia del P. Lagos +8
We examine the properties of atomic hydrogen (HI) associated with galaxies in the EAGLE simulations of galaxy formation. EAGLE's feedback parameters were calibrated to reproduce th…
An HI View of Galaxy Conformity: HI-rich Environment around HI-excess Galaxies
Jing Wang, Paolo Serra, Gyula I. G. Jozsa +9
Using data taken as part of the Bluedisk project we study the connection between neutral hydrogen (HI) in the environment of spiral galaxies and that in the galaxies themselves. We…
SoFiA: a flexible source finder for 3D spectral line data
Paolo Serra, Tobias Westmeier, Nadine Giese +9
We introduce SoFiA, a flexible software application for the detection and parameterization of sources in 3D spectral-line datasets. SoFiA combines for the first time in a single pi…
The Void Galaxy Survey: Morphology and Star Formation Properties of Void Galaxies
B. Beygu, K. Kreckel, J. M. van der Hulst +5
We present the structural and star formation properties of 59 void galaxies as part of the Void Galaxy Survey (VGS). Our aim is to study in detail the physical properties of these…
An observational and theoretical view of the radial distribution of HI gas in galaxies
Jing Wang, Jian Fu, Michael Aumer +7
We analyze the radial distribution of HI gas for 23 disk galaxies with unusually high HI content from the Bluedisk sample, along with a similar-sized sample of "normal" galaxies. W…
Neutral atomic hydrogen (HI) gas evolution in field galaxies at z ~ 0.1 and 0.2
Jonghwan Rhee, Martin A. Zwaan, Frank H. Briggs +4
We measure the neutral atomic hydrogen (HI) gas content of field galaxies at intermediate redshifts of z ~ 0.1 and z ~ 0.2 using hydrogen 21-cm emission lines observed with the Wes…
The Bluedisks project, a study of unusually HI-rich galaxies: I. HI Sizes and Morphology
Jing Wang, Guinevere Kauffmann, Gyula I. G. Józsa +10
We introduce the "Bluedisk" project, a large program at the Westerbork Synthesis Radio Telescope (WSRT) that has mapped the HI in a sample of 23 nearby galaxies with unusually high…
Redundancy Calibration of Phased Array Stations
Parisa Noorishad, Stefan J. Wijnholds, Arnold van Ardenne +1
Our aim is to assess the benefits and limitations of using the redundant visibility information in regular phased array systems for improving the calibration. Regular arrays offer…
The Cosmically Depressed: Life, Sociology and Identity of Voids
Rien van de Weygaert, Erwin Platen, Esra Tigrak +5
We review and discuss aspects of Cosmic Voids that form the background for our Void Galaxy Survey (see accompanying paper by Stanonik et al.). Following a sketch of the general cha…
Extra-planar HI in the starburst galaxy NGC 253
Rense Boomsma, Tom Oosterloo, Filippo Fraternali +2
Observations of the nearby starburst galaxy NGC 253 in the 21-cm line reveal the presence of neutral hydrogen in the halo, up to 12 kpc from the galactic plane. This extra-planar H…
U, B and r band luminosity functions of galaxies in the Coma cluster
Marco Beijersbergen, Henk Hoekstra, Pieter G. van Dokkum +1
We present a deep multi-colour CCD mosaic of the Coma cluster (Abell 1656), covering 5.2 deg^2 in the B and r bands, and 1.3 deg^2 in the U band. This large, homogeneous data set p…
