Exploring the making of a galactic wind in the star-bursting dwarf irregular galaxy IC 10 with LOFAR
(2018-05-11)
Low-mass galaxies are subject to strong galactic outflows, in which cosmic rays may play an important role; they can be best traced with low-frequency radio continuum observations, which are less affected by spectral ageing. ...
Panchromatic SED modelling of spatially-resolved galaxies
(2018-05-11)
We test the efficacy of the energy-balance spectral energy distribution (SED) fitting code MAGPHYS for recovering the spatially resolved properties of a simulated isolated disc galaxy, for which it was not designed. We ...
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 ...
