    • Evidence that the AGN dominates the radio emission in z ~ 1 radio-quiet quasars 

      White, Sarah V.; Jarvis, Matt J.; Kalfountzou, Eleni; Hardcastle, Martin; Verma, Aprajita; Orjales, José M. Cao; Stevens, Jason (2017-02-02)
      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 objects. Previous work at low radio flux-densities ...

    • Investigating the Unification of LOFAR-detected powerful AGN in the Boötes Field 

      Morabito, Leah K.; Williams, W. L.; Duncan, Kenneth J.; Röttgering, H.~J.~A.; Miley, George; Saxena, Aayush; Barthel, Peter; Best, Philip N.; Bruggen, M.; Brunetti, G.; Chyży, K. T.; Engels, D.; Hardcastle, M. J.; Harwood, J. J.; Jarvis, Matt J.; Mahony, E. K.; Prandoni, I.; Shimwell, Timothy W.; Shulevski, Alexander; Tasse, C. (2017-08-01)
      Low radio frequency surveys are important for testing unified models of radio-loud quasars and radio galaxies. Intrinsically similar sources that are randomly oriented on the sky will have different projected linear sizes. ...

    • LOFAR/H-ATLAS: The low-frequency radio luminosity - star-formation rate relation 

      Gurkan, Gulay; Hardcastle, Martin J.; Smith, Daniel; Best, Philip N.; Bourne, Nathan; Calistro-Rivera, Gabriela; Heald, George; Jarvis, Matt J.; Prandoni, Isabella; Rottgering, Huub J. A.; Sabater, Jose; Shimwell, Tim; Tasse, Cyril; Williams, Wendy L. (2018-04-11)
      Radio emission is a key indicator of star-formation activity in galaxies, but the radio luminosity-star formation relation has to date been studied almost exclusively at frequencies of 1.4 GHz or above. At lower radio ...

    • The New Galaxy Evolution Paradigm Revealed by the Herschel Surveys 

      Eales, Stephen A.; Smith, Daniel; Bourne, Nathan; Loveday, Jon; Rowlands, Kate; Werf, Paul van der; Driver, Simon; Dunne, Loretta; Dye, Simon; Furlanetto, Christina; Ivison, R. J.; Maddox, Steve J.; Robotham, Aaron S. G.; Smith, Matthew W.L.; Taylor, Edward N.; Valiante, Elisabetta; Wright, Angus; Cigan, Philip; de Zotti, Gianfranco; Jarvis, Matt J.; Marchetti, Lucia; Michalowski, Michal J.; Phillipps, Steve; Viaene, Sebastian; Vlahakis, Catherine (2018-01-21)
      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 surveys reveal (1) that there was rapid galaxy ...

    • Photometric redshifts for the next generation of deep radio continuum surveys - I. Template fitting 

      Duncan, Kenneth J.; Brown, Michael J. I.; Williams, Wendy L.; Best, Philip N.; Buat, Veronique; Burgarella, Denis; Jarvis, Matt J.; Malek, Katarzyna; Oliver, S. J.; Rottgering, Huub J. A.; Smith, Daniel J. B. (2018-01-11)
      We present a study of photometric redshift performance for galaxies and active galactic nuclei detected in deep radio continuum surveys. Using two multiwavelength data sets, over the NOAO Deep Wide Field Survey Boötes and ...

    • The wide-field, multiplexed, spectroscopic facility WEAVE: Survey design, overview, and simulated implementation 

      WEAVE consortium; Jin, Shoko; Trager, Scott C.; Dalton, Gavin B.; Aguerri, J. Alfonso L.; Drew, J. E.; Falcón-Barroso, Jesús; Gänsicke, Boris T.; Hill, Vanessa; Iovino, Angela; Pieri, Matthew M.; Poggianti, Bianca M.; Smith, D. J. B.; Vallenari, Antonella; Abrams, Don Carlos; Aguado, David S.; Antoja, Teresa; Aragón-Salamanca, Alfonso; Ascasibar, Yago; Babusiaux, Carine; Balcells, Marc; Barrena, R.; Battaglia, Giuseppina; Belokurov, Vasily; Bensby, Thomas; Bonifacio, Piercarlo; Bragaglia, Angela; Carrasco, Esperanza; Carrera, Ricardo; Cornwell, Daniel J.; Domínguez-Palmero, Lilian; Duncan, Kenneth J.; Famaey, Benoit; Fariña, Cecilia; Gonzalez, Oscar A.; Guest, Steve; Hatch, Nina A.; Hess, Kelley M.; Hoskin, Matthew J.; Irwin, Mike; Knapen, Johan H.; Monguió, Maria; Raddi, Roberto; Drake, Alyssa; Gledhill, T. M.; Hardcastle, Martin J.; Harris, Amy; Jarvis, Matt J.; Read, Shaun C.; Williams, Wendy L.; Wright, Nicholas J. (2023-03-11)
      WEAVE, the new wide-field, massively multiplexed spectroscopic survey facility for the William Herschel Telescope, will see first light in late 2022. WEAVE comprises a new 2-degree field-of-view prime-focus corrector system, ...
