LOFAR Deep Fields: Probing the sub-mJy regime of polarized extragalactic sources in ELAIS-N1. I. The catalog
S. Piras, C. Horellou, J. E. Conway +16
The aim of this study is to probe the sub-mJy polarized source population with LOFAR. We present the method used to stack LOFAR polarization datasets, the resulting catalog of pola…
The contribution of discrete sources to the sky temperature at 144 MHz
M. J. Hardcastle, T. W. Shimwell, C. Tasse +7
In recent years, the level of the extragalactic radio background has become a point of considerable interest, with some lines of argument pointing to an entirely new cosmological s…
One- and Two-point Source Statistics from the LOFAR Two-metre Sky Survey First Data Release
Thilo M. Siewert, Catherine Hale, Nitesh Bhardwaj +13
The LOFAR Two-metre Sky Survey (LoTSS) will map the complete Northern sky and provide an excellent opportunity to study the distribution and evolution of the large-scale structure…
LOFAR 150-MHz observations of the Boötes field: Catalogue and Source Counts
W. L. Williams, R. J. van Weeren, H. J. A. Röttgering +32
We present the first wide area (19 deg), deep ( μJy beam), high resolution ( arcsec) LOFAR High Band Antenna image of the Boötes field ma…
Effects of the environment on galaxies in the Catalogue of Isolated Galaxies: physical satellites and large scale structure
M. Argudo-Fernández, S. Verley, G. Bergond +8
We aim to identify and quantify the effects of the satellite distribution around a sample of galaxies in the Catalogue of Isolated Galaxies (CIG), as well as the effects of the Lar…
The AMIGA sample of isolated galaxies XII. Revision of the isolation degree for AMIGA galaxies using the SDSS
M. Argudo-Fernández, S. Verley, G. Bergond +9
In the framework of the AMIGA project we present a revision of the environment for galaxies in the Catalogue of Isolated Galaxies (CIG, Karachentseva 1973) using the ninth data rel…
Effect of the interactions and environment on nuclear activity
J. Sabater, P. N. Best, M. Argudo-Fernández
We present a study of the prevalence of optical and radio nuclear activity with respect to the environment and interactions in a sample of SDSS galaxies. We defined a local density…
The AMIGA sample of isolated galaxies IX. Molecular gas properties
U. Lisenfeld, D. Espada, L. Verdes-Montenegro +7
Aims: We characterize the molecular gas content using CO emission of a redshift-limited subsample of isolated galaxies from the AMIGA (Analysis of the interstellar Medium of Isolat…
The AMIGA sample of isolated galaxies: VIII. The rate of asymmetric HI profiles in spiral galaxies
D. Espada, L. Verdes-Montenegro, W. K. Huchtmeier +4
(abridged) Measures of the HI properties of a galaxy are among the most sensitive interaction diagnostic at our disposal. We report here on a study of HI profile asymmetries (e.g.,…
Molecular gas properties of galaxies: The SMA CO(2-1) B0DEGA legacy project
D. Espada, S. Martin, P. -Y. Hsieh +7
In the last two decades high resolution (< 5 arcsec) CO observations for ~ 150 galaxies have provided a wealth of information about the molecular gas morphologies in the circumnucl…
Setting the normalcy level of HI properties in isolated galaxies
D. Espada, L. Verdes-Montenegro, E. Athanassoula +8
Studying the atomic gas (HI) properties of the most isolated galaxies is essential to quantify the effect that the environment exerts on this sensitive component of the interstella…
AMIGA project: Quantification of the isolation of 950 CIG galaxies
S. Verley, S. Leon, L. Verdes-Montenegro +7
The role of the environment on galaxy evolution is still not fully understood. In order to quantify and set limits on the role of nurture one must identify and study a sample of is…
