    • ACA [CI] observations of the starburst galaxy NGC 253 

      Krips, M.; Martín, S.; Sakamoto, K.; Aalto, S.; Bisbas, T.~G.; Bolatto, A.~D.; Downes, D.; Eckart, A.; Feruglio, C.; García-Burillo, S.; Geach, J.; Greve, T.~R.; König, S.; Matsushita, S.; Neri, R.; Offner, S.; Peck, A.~B.; Viti, S.; Wagg, J. (2016-08-01)
      Context. Carbon monoxide (CO) is widely used as a tracer of the molecular gas in almost all types of environments. However, several shortcomings of CO complicate usaging it as H2 tracer, such as its optical depth effects, ...

    • An Extreme Starburst in the Core of a Rich Galaxy Cluster at z = 1.7 

      Webb, T.; Noble, A.; DeGroot, A.; Wilson, G.; Muzzin, A.; Bonaventura, N.; Cooper, M.; Delahaye, A.; Foltz, R.; Lidman, C.; Surace, J.; Yee, H.~K.~C.; Chapman, S.; Dunne, L.; Geach, J.; Hayden, B.; Hildebrandt, H.; Huang, J.; Pope, A.; Smith, M.~W.~L.; Perlmutter, S.; Tudorica, A. (2015-08-21)
      We have discovered an optically rich galaxy cluster at z = 1.7089 with star formation occurring in close proximity to the central galaxy. The system, SpARCS104922.6+564032.5, was detected within the Spitzer Adaptation of ...

    • GLACE survey: OSIRIS/GTC tuneable filter H$ imaging of the rich galaxy cluster ZwCl 0024.0+1652 at z = 0.395. I. Survey presentation, TF data reduction techniques, and catalogue 

      Sánchez-Portal, M.; Pintos-Castro, I.; Pérez-Martínez, R.; Cepa, J.; Pérez García, A.~M.; Domínguez-Sánchez, H.; Bongiovanni, A.; Serra, A.~L.; Alfaro, E.; Altieri, B.; Aragón-Salamanca, A.; Balkowski, C.; Biviano, A.; Bremer, M.; Castander, F.; Castañeda, H.; Castro-Rodríguez, N.; Chies-Santos, A.~L.; Coia, D.; Diaferio, A.; Duc, P.~A.; Ederoclite, A.; Geach, J.; González-Serrano, I.; Haines, C.~P.; McBreen, B.; Metcalfe, L.; Oteo, I.; Pérez-Fournón, I.; Poggianti, B.; Polednikova, J.; Ramón-Pérez, M.; Rodríguez-Espinosa, J.~M.; Santos, J.~S.; Smail, I.; Smith, G.~P.; Temporin, S.; Valtchanov, I. (2015-06-01)
      The cores of clusters at 0 ≲ z ≲ 1 are dominated by quiescent early-type galaxies, whereas the field is dominated by star-forming late-type galaxies. Clusters grow through the accretion of galaxies and groups from the ...

    • Herschel -ATLAS : Rapid evolution of dust in galaxies over the last 5 billion years 

      Dunne, L.; Maddox, S. J.; Rowlands, K.; Smith, Daniel; Bourne, N.; Rigby, E.E.; Gomez, H.L.; Dye, S.; Eales, S.; Auld, R.; Dariush, A.; Pascale, E.; Pohlen, M.; da Cunha, E.; Charlot, S.; Baes, M.; Fritz, J.; Bonfield, D.G.; Jarvis, M.J.; Thompson, Mark; Buttiglione, S.; de Zotti, G.; Cava, A.; Clements, D.

E.; Rodighiero, G.; Serjeant, S.; Temi, P.; Tuffs, R.; Vlahakis, C. (2011-10-01)
      We present the first direct and unbiased measurement of the evolution of the dust mass function of galaxies over the past 5 billion years of cosmic history using data from the Science Demonstration Phase of the ...

    • Red but not dead: unveiling the star-forming far-infrared spectral energy distribution of SpARCS brightest cluster galaxies at 0 $ z $ 1.8 

      Bonaventura, N.~R.; Webb, T.~M.~A.; Muzzin, A.; Noble, A.; Lidman, C.; Wilson, G.; Yee, H.~K.~C.; Geach, J.; Hezaveh, Y.; Shupe, D.; Surace, J. (2017-08-01)
      We present the results of a Spitzer/Herschel infrared photometric analysis of the largest (716) and the highest-redshift (z = 1.8) sample of brightest cluster galaxies (BCGs), those from the Spitzer Adaptation of the ...

    • The SCUBA-2 Cosmology Legacy Survey: the clustering of submillimetre galaxies in the UKIDSS UDS field 

      Wilkinson, A.; Almaini, O.; Chen, C.-C.; Smail, I.; Arumugam, V.; Blain, A.; Chapin, E.~L.; Chapman, S.~C.; Conselice, C.~J.; Cowley, W.~I.; Dunlop, J.~S.; Farrah, D.; Geach, J.; Hartley, W.~G.; Ivison, R.~J.; Maltby, D.~T.; Michalowski, M.~J.; Mortlock, A.; Scott, D.; Simpson, C.; Simpson, J.~M.; van der Werf, P.; Wild, V. (2017-01-11)
      Submillimetre galaxies (SMGs) are among the most luminous dusty galaxies in the Universe, but their true nature remains unclear; are SMGs the progenitors of the massive elliptical galaxies we see in the local Universe, or ...
