Normal black holes in bulge-less galaxies: the largely quiescent, merger-free growth of black holes over cosmic time
(2018-05-11)
Understanding the processes that drive the formation of black holes (BHs) is a key topic in observational cosmology. While the observed M BH-M Bulge correlation in bulge-dominated galaxies is thought to be produced by major ...
Particle content, radio-galaxy morphology and jet power : all radio-loud AGN are not equal
(2018-05-11)
Ongoing and future radio surveys aim to trace the evolution of black hole growth and feedback from active galactic nuclei (AGNs) throughout cosmic time; however, there remain major uncertainties in translating radio ...
Observational constraints on the physical nature of submillimetre source multiplicity : chance projections are common
(2018-05-11)
Interferometric observations have demonstrated that a significant fraction of single-dish submillimetre (submm) sources are blends of multiple submm galaxies (SMGs), but the nature of this multiplicity, i.e. whether the ...
Galaxy pairs in the SDSS - XIII. The connection between enhanced star formation and molecular gas properties in galaxy mergers.
(2018-05-11)
We investigate the connection between star formation and molecular gas properties in galaxy mergers at low redshift (z ≤ 0.06). The study we present is based on IRAM 30-m CO(1-0) observations of 11 galaxies with a close ...
The second Herschel-ATLAS Data Release - III. Optical and near-infrared counterparts in the North Galactic Plane field
(2018-05-01)
This paper forms part of the second major public data release of the Herschel Astrophysical Terahertz Large Area Survey (H-ATLAS). In this work, we describe the identification of optical and near-infrared counterparts to ...
Herschel and SCUBA-2 observations of dust emission in a sample of Planck cold clumps
(2018-04-27)
Context. Analysis of all-sky Planck submillimetre observations and the IRAS 100 μm data has led to the detection of a population of Galactic cold clumps. The clumps can be used to study star formation and dust properties ...
Abell 1367: a high fraction of late-type galaxies displaying HI morphological and kinematic perturbations
(2018-04-21)
To investigate the effects the cluster environment has on late-type galaxies (LTGs), we studied HI perturbation signatures for all Abell 1367 LTGs with HI detections. We used new Very Large Array HI observations combined ...
The binary fraction of planetary nebula central stars - III. the promise of VPHAS+
(2018-04-21)
The majority of planetary nebulae (PNe) are not spherical, and current single-star models cannot adequately explain all the morphologies we observe. This has led to the Binary Hypothesis, which states that PNe are ...
A Spatially Resolved Radio Spectral Index Study of the Dwarf Irregular Galaxy NGC\,1569
(2018-04-21)
We study the resolved radio continuum spectral energy distribution of the dwarf irregular galaxy, NGC 1569, on a beam-by-beam basis to isolate and study its spatially resolved radio emission characteristics. Utilizing ...
Remnant radio-loud AGN in the Herschel-ATLAS field
(2018-04-21)
Only a small fraction of observed active galactic nuclei (AGN) display large-scale radio emission associated with jets, yet these radio-loud AGN have become increasingly important in models of galaxy evolution. In determining ...
