    • A megacam survey of outer halo satellites. I. description of the survey 
      Muñoz Vidal, Ricardo Rodrigo; Cote, Patrick; Santana, Felipe; Geha, Marla; Simón, Joshua D.; Oyarzún, Grecco A.; Stetson, Peter B.; Djorgovski, S. G. (IOP Publishing, 2018-06-10)
      We describe a deep, systematic imaging study of satellites in the outer halo of the Milky Way. Our sample consists of 58 stellar overdensities-i.e., substructures classified as either globular clusters, classical dwarf ...
    • A megacam survey of outer halo satellites. III. Photometric and structural parameters 
      Muñoz Vidal, Ricardo Rodrigo; Cote, Patrick; Santana, Felipe; Geha, Marla; Simón, Joshua D.; Oyarzún, Grecco A.; Stetson, Peter B.; Djorgovski, S. G. (The American Astronomical Society, 2018-06-10)
      We present structural parameters from a wide-field homogeneous imaging survey of Milky Way satellites carried out with the MegaCam imagers on the 3.6 m Canada-France-Hawaii Telescope and 6.5 m Magellan-Clay telescope. Our ...
    • 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 ...
    • Recovering star formation histories: Integrated-light analyses vs. stellar colour-magnitude diagrams 
      Ruiz Lara, T.; Pérez, I.; Gallart, Carme; Alloin, D.; Monelli, M.; Koleva, M.; Pompei, E.; Beasley, M.; Sánchez Blázquez, P.; Florido, E.; Aparicio, Antonio; Fleurence, E.; Hardy Raskovan, Eduardo; Hidalgo, S.; Raimann, D. (EDP Sciences, 2015)
      Context. Accurate star formation histories (SFHs) of galaxies are fundamental for understanding the build-up of their stellar content. However, the most accurate SFHs - those obtained from colour-magnitude diagrams (CMDs) ...
    • 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 
      Merluzzi, P.; Busarello, G.; Haines, Chris; Mercurio, A.; Okabe, N.; Pimbblet, K. J.; Dopita, M. A.; Grado, A.; Limatola, L.; Bourdin, H.; Mazzotta, P.; Capaccioli, M.; Napolitano, N. R.; Schipani, P. (Royal Astronomical Society, 2015)
      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 intrinsic reddening of the Magellanic clouds as traced by background galaxies – II. The small Magellanic cloud 
      Bell, Cameron; Cioni, María Rosa; Wright, A. H.; Rubele, Stefano; Nidever, David L.; Tatton, Ben L.; Van Loon, Jacco Th.; Zaritsky, Dennis; Choi, Yumi; Choudhury, Samyaday; Clementini, Gisella; Grijs, Richard de; Vanov, Valentin D.; Majewski, Steven R.; Marconi, Marcella; Martínez Delgado, David; Massana, Pol; Muñoz, Ricardo R.; Niederhofer, Florian; Noel, Noelia E. D.; Oliveira, Joana M.; Olsen, Knut; Pennock, Clara M; Ripepi, V.; Subramanian, Smitha; Vivas, A. Katherina. (Oxford University Press, 2020)
      We present a map of the total intrinsic reddening across similar or equal to 34 deg(2) of the Small Magellanic Cloud (SMC) derived using optical (ugriz) and near-infrared (IR; YJK(s)) spectral energy distributions (SEDs) ...
