Improving Photometric Redshift Estimation using GPz: size information, post processing and improved photometry
Zahra Gomes, Matt J. Jarvis, Ibrahim A. Almosallam +1
The next generation of large scale imaging surveys (such as those conducted with the Large Synoptic Survey Telescope and Euclid) will require accurate photometric redshifts in orde…
Photometric redshifts for the next generation of deep radio continuum surveys - II. Gaussian processes and hybrid estimates
Kenneth J Duncan, Matt J. Jarvis, Michael J. I. Brown +1
Building on the first paper in this series (Duncan et al. 2018), we present a study investigating the performance of Gaussian process photometric redshift (photo-z) estimates for g…
LOFAR-Boötes: Properties of high- and low-excitation radio galaxies at
W. L. Williams, G. Calistro Rivera, P. N. Best +13
This paper presents a study of the redshift evolution of radio-loud active galactic nuclei (AGN) as a function of the properties of their galaxy hosts in the Boötes field. To achie…
The clustering and bias of radio-selected AGN and star-forming galaxies in the COSMOS field
C. L. Hale, M. J. Jarvis, I. Delvecchio +4
Dark matter haloes in which galaxies reside are likely to have a significant impact on their evolution. We investigate the link between dark matter haloes and their constituent gal…
SPLASH-SXDF Multi-wavelength Photometric Catalog
Vihang Mehta, Claudia Scarlata, Peter Capak +19
We present a multi-wavelength catalog in the Subaru-XMM Deep Field (SXDF) as part of the Spitzer Large Area Survey with Hyper-Suprime-Cam (SPLASH). We include the newly acquired op…
The New Galaxy Evolution Paradigm Revealed by the Herschel Surveys
Stephen Eales, Dan Smith, Nathan Bourne +22
The Herschel Space Observatory has revealed a very different galaxyscape from that shown by optical surveys which presents a challenge for galaxy-evolution models. The Herschel sur…
Photometric redshifts for the next generation of deep radio continuum surveys - I: Template fitting
Kenneth J Duncan, Michael J. I. Brown, Wendy L. Williams +8
We present a study of photometric redshift performance for galaxies and active galactic nuclei detected in deep radio continuum surveys. Using two multi-wavelength datasets, over t…
The MeerKAT International GHz Tiered Extragalactic Exploration (MIGHTEE) Survey
Matt J. Jarvis, A. R. Taylor, I. Agudo +54
The MIGHTEE large survey project will survey four of the most well-studied extragalactic deep fields, totalling 20 square degrees to Jy sensitivity at Giga-Hertz frequencies, as…
Large Synoptic Survey Telescope Galaxies Science Roadmap
Brant E. Robertson, Manda Banerji, Michael C. Cooper +47
The Large Synoptic Survey Telescope (LSST) will enable revolutionary studies of galaxies, dark matter, and black holes over cosmic time. The LSST Galaxies Science Collaboration has…
A complete distribution of redshifts for sub-millimetre galaxies in the SCUBA-2 Cosmology Legacy Survey UDS field
D. J. B. Smith, C. C. Hayward, M. J. Jarvis +1
Sub-milllimetre galaxies (SMGs) are some of the most luminous star-forming galaxies in the Universe, however their properties remain hard to determine due to the difficulty of iden…
The KMOS Redshift One Spectroscopic Survey (KROSS): the origin of disk turbulence in z~0.9 star-forming galaxies
H. L. Johnson, C. M. Harrison, A. M. Swinbank +27
We analyse the velocity dispersion properties of 472 z~0.9 star-forming galaxies observed as part of the KMOS Redshift One Spectroscopic Survey (KROSS). The majority of this sample…
The prevalence of core emission in faint radio galaxies in the SKA Simulated Skies
Imogen H. Whittam, Matt J. Jarvis, David A. Green +2
Empirical simulations based on extrapolations from well-established low-frequency ( GHz) surveys fail to accurately model the faint, high frequency (~GHz) source populati…
Observational evidence that positive and negative AGN feedback depends on galaxy mass and jet power
E. Kalfountzou, J. A. Stevens, M. J. Jarvis +6
Several studies support the existence of a link between the AGN and star formation activity. Radio jets have been argued to be an ideal mechanism for direct interaction between the…
Galaxy And Mass Assembly (GAMA): The environments of high- and low- excitation radio galaxies
J. H. Y. Ching, S. M. Croom, E. M. Sadler +18
We study the environments of low- and high- excitation radio galaxies (LERGs and HERGs respectively) in the redshift range , using a sample of 399 radio galaxies an…
Evidence that the AGN dominates the radio emission in z ~ 1 radio-quiet quasars
Sarah V. White, Matt J. Jarvis, Eleni Kalfountzou +4
In order to understand the role of radio-quiet quasars (RQQs) in galaxy evolution, we must determine the relative levels of accretion and star-formation activity within these objec…
