    • ALMA Observations of Elias 2-24: A Protoplanetary Disk with Multiple Gaps in the Ophiuchus Molecular Cloud 
      Cieza, Lucas; Casassus Montero, Simón; Pérez, Sebastián; Hales, Antonio; Cárcamo, Miguel; Ansdell, Megan; Avenhaus, Henning; Bayo, Amelia; Bertrang, Gesa; Cánovas, Hector; Christiaens, Valentin; Dent, William; Ferrero, Gabriel; Gamen, Roberto; Olofsson, Johan; Orcajo, Santiago; Osses, Axel; Peña-Ramirez, Karla; Principe, David; Ruíz-Rodríguez, Dary; Schreiber, Matthias; Van der Plas, Gerrit; Williams, Jonathan; Zurlo, Alice (Institute of Physics Publishing, 2017)
      We present ALMA 1.3 mm continuum observations at 0."2 (25 au) resolution of Elias 2-24, one of the largest andbrightest protoplanetary disks in the Ophiuchus Molecular Cloud, and we report the presence of three partiallyresolved ...
    • Improving signal-to-noise in the direct imaging of exoplanets and circumstellar disks with MLOCI 
      Wahhaj, Zahed; Cieza, Lucas; Mawet, Dimitri; Yang, Bin; Canovas, Héctor; Boer, Jozua de; Casassus Montero, Simón; Ménard, Francois; Schreiber, Matthias; Liu, Michael; Biller, Beth; Nielsen, Eric; Hayward, Thomas (EDP Sciences, 2015)
      We present a new algorithm designed to improve the signal-to-noise ratio (S/N) of point and extended source detections around bright stars in direct imaging data. One of our innovations is that we insert simulated point ...
