    • Luminous infrared galaxies. III. Multiple merger, extended massive star formation, galactic wind, and nuclear inflow in NGC 3256 

      Lipari, Sebastian; Díaz, Rubén Joaquín; Taniguchi, Y.; Terlevich, Roberto; Dottori, Horacio Alberto; Carranza, Gustavo Jose (2000) [Artículo de periódico]
      We report detailed evidence for multiple merger, extended massive star formation, galactic wind, and circular/noncircular motions in the luminous infrared galaxy NGC 3256, based on observations of highresolution imaging ...

    • Optical spectroscopic properties of a sample of interacting galaxies 

      Donzelli, Carlos J.; Pastoriza, Miriani Griselda (1997) [Artículo de periódico]
      We present spectroscopic observations of 83 galaxies from a sample of 49 pairs of optically selected interacting galaxies, most of them previously unobserved. These pairs consist of a main galaxy (component A) and a companion ...

    • SDSS IV MaNGA : star-formation driven biconical outflows in face-on galaxies 

      Bizyaev, D.; Chen, Yan-Mei; Shi, Yong; Roy, Namrata; Riffel, Rogério; Riffel, Rogemar André; Fernández-Trincado, José Gregorio (2022) [Artículo de periódico]
      We find 132 face-on and low inclination galaxies with central star formation driven biconical gas outflows (FSFB) in the SDSS MaNGA (Mapping Nearby Galaxies at APO) survey. The FSFB galaxies show either double peaked or ...

    • Spatially resolved self-consistent spectral modelling of jellyfish galaxies from MUSE with FADO : trends with mass and stripping intensity 

      Azevedo, Gabriel Maciel; Chies-Santos, Ana Leonor; Riffel, Rogério; Gomes, Jean Michel Silva de Miranda; Lassen, Augusto Eduardo; Benedetti, João Pedro Verardo; Souza, Rafael da Silva de; Xu, Quanfeng (2023) [Artículo de periódico]
      We present a spatially resolved stellar population analysis of 61 jellyfish galaxies and 47 control galaxies observed with ESO/MUSE attempting to understand the general trends of the stellar populations as a function of ...

    • Spectroscopic observations of merging galaxies 

      Donzelli, Carlos J.; Pastoriza, Miriani Griselda (2000) [Artículo de periódico]
      In this paper we describe the spectroscopic and infrared properties of a sample of 25 merging galaxy pairs, selected from the catalog of Arp & Madore, and we compare them with those observed in a similar sample of interacting ...

    • Study of McLeish's interacting object 

      Díaz, Rubén Joaquín; Rodrigues, Irapuan; Dottori, Horacio Alberto; Carranza, Gustavo Jose (2000) [Artículo de periódico]
      We discuss the morphology, kinematics, and physical conditions of the emitting gas of the interacting system IRAS 20048—6621. We present as well numerical simulations of this interacting system, discovered by David McLeish ...

    • Study of the interacting system NGC 6845 

      Rodrigues, Irapuan; Dottori, Horacio Alberto; Brinks, Elias; Mirabel, I. Felix (1999) [Artículo de periódico]
      We present optical spectroscopy, B, V , R, and I CCD photometry, and VLA neutral hydrogen observations of the interacting quartet NGC 6845, also know as Klemola 30. NGC 6845 A, the dominant component, sports a broad and ...
