    • Developing a victorious strategy to the second strong gravitational lensing data challenge 

      De Bom, Clécio Roque; Fraga, Bernardo Machado de Oliveira; Dias, Luciana Olivia; Schubert, Patrick; Valentin, Manuel Blanco; Furlanetto, Cristina; Makler, Martín; Teles, K.; Albuquerque, M.P.; Metcalf, Robert Benton (2022) [Artigo de periódico]
      Strong lensing is a powerful probe of the matter distribution in galaxies and clusters and a relevant tool for cosmography. Analyses of strong gravitational lenses with deep learning have become a popular approach due to ...

    • Globular cluster systems of relic galaxies 

      Alamo-Martínez, Karla A.; Chies-Santos, Ana Leonor; Beasley, Michael; Freitas, Rodrigo Flores de; Furlanetto, Cristina; Trevisan, Marina; Müller, Allan Schnorr; Leaman, Ryan; Bonatto, Charles Jose (2021) [Artigo de periódico]
      We analyse the globular cluster (GC) systems of a sample of 15 massive, compact early-type galaxies (ETGs), 13 of which have already been identified as good relic galaxy candidates on the basis of their compact morphologies, ...

    • Modelling high-resolution ALMA observations of strongly lensed dusty star-forming galaxies detected by Herschel 

      Maresca, Jacob; Dye, Simon; Amvrosiadis, Aristeidis; Bendo, George; Cooray, Asantha Roshan; De Zotti, Gianfranco; Dunne, Loretta; Eales, Stephen A.; Furlanetto, Cristina; Gonzalez-Nuevo, Joaquin; Greener, Michael; Ivison, Rob J.; Lapi, Andrea; Negrello, Mattia; Riechers, Dominick A.; Serjeant, Stephen; Tergolina, Mônica; Wardlow, Julie (2022) [Artigo de periódico]
      We present modelling of ∼0.1 arcsec resolution Atacama Large Millimetre/submillimetre Array imaging of seven strong gravitationally lensed galaxies detected by the Herschel Space Observatory. Four of these systems are ...

    • Modelling high-resolution ALMA observations of strongly lensed highly star-forming galaxies detected by Herschel 

      Dye, Simon; Furlanetto, Cristina; Dunne, Loretta; Eales, Stephen A.; Negrello, Mattia; Nayyeri, Hooshang; Werf, Paul Peter van der; Serjeant, Stephen; Farrah, Duncan G.; Michalowski, Michal; Baes, Maarten; Marchetti, Lucia; Cooray, Asantha Roshan; Riechers, Dominick A.; Amvrosiadis, Aristeidis (2018) [Artigo de periódico]
      We have modelled ∼0.1 arcsec resolution Atacama Large Millimetre/submillimeter Array imaging of six strong gravitationally lensed galaxies detected by the Herschel Space Observatory. Our modelling recovers mass properties ...

    • Relic galaxy analogues in TNG50 simulation : the formation pathways of surviving red nuggets in a cosmological simulation 

      Freitas, Rodrigo Flores de; Chies-Santos, Ana Leonor; Furlanetto, Cristina; de Rossi, María Emilia; Ferreira, Leonardo de Albernaz; Zenocratti, Lucas; Alamo-Martínez, Karla A. (2022) [Artigo de periódico]
      Relic galaxies are massive compact quiescent galaxies that formed at high-redshift and remained almost unchanged since then. In this work, we search for analogues to relic galaxies in the TNG50 cosmological simulations to ...

    • A simple prescription for simulating and characterizing gravitational arcs 

      Furlanetto, Cristina; Santiago, Basilio Xavier; Makler, Martín; De Bom, Clécio Roque; Brandt, Carlos Henrique; Fausti Neto, Angelo; Ferreira, Pedro da Cunha; Costa, Luiz N. da; Maia, Marcio Antonio Geimba (2013) [Artigo de periódico]
      Simple models of gravitational arcs are crucial for simulating large samples of these objects with full control of the input parameters. These models also provide approximate and automated estimates of the shape and structure ...

    • The causes of the red sequence, the blue cloud, the green valley, and the green mountain 

      Eales, Stephen A.; Furlanetto, Cristina; Wright, Angus (2018) [Artigo de periódico]
      The galaxies found in optical surveys fall in two distinct regions of a diagram of optical colour versus absolute magnitude: the red sequence and the blue cloud, with the green valley in between. We show that the galaxies ...

    • The Herschel-ATLAS data release 2. Paper II : catalogs of far-infrared and submillimeter sources in the fields at the south and north Galactic poles 

      Maddox, Steve J.; Valiante, Elisabetta; Cigan, Phillip J.; Dunne, Loretta; Eales, Stephen A.; Smith, Matthew Wilson L.; Dye, Simon; Furlanetto, Cristina; Ibar, Eduardo; De Zotti, Gianfranco; Millard, Jenifer; Bourne, Nathan; Gomez, Haley L.; Ivison, Rob J.; Scott, Douglas J.; Valtchanov, Ivan (2018) [Artigo de periódico]
      The Herschel Astrophysical Terahertz Large Area Survey (H-ATLAS) is a survey of 660 deg2 with the PACS and SPIRE cameras in five photometric bands: 100, 160, 250, 350, and 500 μm. This is the second of three papers describing ...

    • The new galaxy evolution paradigm revealed by the Herschel surveys 

      Eales, Stephen A.; Furlanetto, Cristina; Vlahakis, Catherine (2018) [Artigo de periódico]
      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 ...

    • The puzzling origin of massive compact galaxies in MaNGA 

      Müller, Allan Schnorr; Trevisan, Marina; Riffel, Rogério; Chies-Santos, Ana Leonor; Furlanetto, Cristina; Ricci, Tiago Vecchi; Lohmann, Felipe Schmidt; Freitas, Rodrigo Flores de; Mallmann, Nícolas Dullius; Alamo-Martínez, Karla A. (2021) [Artigo de periódico]
      We characterized the kinematics, morphology, and stellar population (SP) properties of a sample of massive compact quiescent galaxies (MCGs, 10 log M /M 11 and re ∼ 1–3 kpc) in the MaNGA Survey, with the goal of constraining ...
