    • Detection of 20-30 h(-1) Mpc-scale galaxy structures embedded in 100 h(-1) Mpc-scale structures of quasars ... 
      Haines, Chris; Campusano, Luis E.; Clowes, R. G. (EDP SCIENCES, 2004-07)
      We report the finding of two large-scale structures of galaxies in a 40 x 35 arcmin(2) field embedded in a 25 deg(2) area where two 100 h(-1) Mpc-scale structures of quasars and Mg II absorbers at z similar or equal to 0.8 ...
    • Dry merger rate and post-merger fraction in the Coma cluster core 
      Cordero, Juan P.; Campusano Brown, Luis; Propris, Roberto de; Haines, Chris; Weinzirl, Tim; Jogee, Shardha (The American Astronomical Society, 2016)
      A We evaluate the dry merger activity in the Coma cluster, using a spectroscopically complete sample of 70 red-sequence (RS) galaxies, most of which (similar to 75%) are located within 0.2R(200) (similar to 0.5 Mpc) from ...
    • GLACE survey: OSIRIS/GTC tuneable filter H alpha imaging of the rich galaxy cluster ZwCl 0024.0+1652 at z=0.395 
      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, Chris; 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. (ESA, 2015)
      The cores of clusters at 0 less than or similar to z less than or similar to 1 are dominated by quiescent early-type galaxies, whereas the field is dominated by star-forming late-type galaxies. Clusters grow through the ...
    • A herschel study of 24 mu m-selected AGNs and their host galaxies 
      Xu, Lei; Rieke, G. H.; Egami, E.; Pereira, M. J.; Haines, Chris; Smith, G. P. (IOP Publishing, 2015)
      We present a sample of 290 24 mu m-selected active galactic nuclei (AGNs) mostly at z similar to 0.3-2.5, within 5.2 deg(2) distributed as 25' x 25' fields around each of 30 galaxy clusters in the Local Cluster Substructure ...
    • LoCuSS: Testing hydrostatic equilibrium in galaxy clusters 
      Smith, G. P.; Mazzotta, P.; Okabe, N.; Ziparo, F.; Mulroy, S. L.; Babul, A.; Finoguenov, A.; McCarthy, I. G.; Lieu, M.; Bahé, Y. M.; Bourdin, H.; Evrard, A. E.; Futamase, T.; Haines, Chris; Jauzac, M.; Marrone, D. P.; Martino, R.; May, P. E.; Taylor, J. E.; Umetsu, K. (Oxford University Press, 2016)
      We test the assumption of hydrostatic equilibrium in an X-ray luminosity selected sample of 50 galaxy clusters at 0.15 < z < 0.3 from the Local Cluster Substructure Survey (LoCuSS). Our weak-lensing measurements of M500 ...
    • LoCuSS: the slow quenching of star formation in cluster galaxies and the need for pre-processing 
      Haines, Chris; Pereira, M. J.; Smith, G. P.; Egami, E.; Babul, A.; Finoguenov, A.; Ziparo, F.; McGee, S. L.; Rawle, T. D.; Okabe, N.; Moran, S. M. (IOP Publishing, 2015)
      We present a study of the spatial distribution and kinematics of star-forming galaxies in 30 massive clusters at 0.15 < z < 0.30, combining wide-field Spitzer 24 mu m and GALEX near-ultraviolet imaging with highly complete ...
    • The relation between luminous AGNs and star formation in their host galaxies 
      Xu, Lei; Rieke, G. H.; Egami, E.; Haines, Chris; Pereira, M. J.; Smith, G. P. (IOP Publishing, 2015)
      We study the relation of active galactic nuclei (AGNs) to star formation in their host galaxies. Our sample includes 205 Type-1 and 85 Type-2 AGNs, 162 detected with Herschel, from fields surrounding 30 galaxy clusters in ...
    • Shapley Supercluster Survey: construction of the photometric catalogues and i-band data release 
      Mercurio, A.; Merluzzi, P.; Busarello, G.; Grado, A.; Limatola, L.; Haines, Chris; Brescia, M.; Cavuoti, S.; Dopita, M.; Dall’Ora, M.; Capaccioli, M.; Napolitano, N.; Pimbblet, K. A. (Oxford University Press, 2015)
      The Shapley Supercluster Survey is a multi-wavelength survey covering an area of similar to 23 deg(2) (similar to 260 Mpc(2) at z = 0.048) around the supercluster core, including nine Abell and two poor clusters, having ...
    • Shapley Supercluster Survey: Galaxy evolution from filaments to cluster cores

      We present an overview of a multiwavelength survey of the Shapley Supercluster (SSC; z ∼ 0.05) covering a contiguous area of 260 h −2 70 Mpc2 including the supercluster core. The project main aim is to quantify the ...
    • The galaxy environment of a quasar at z=1.226: a possible cluster merger
