  • SDSS IV MaNGA - spatially resolved diagnostic diagrams : a proof that many galaxies are LIERs 

    Belfiore, Francesco; Maiolino, Roberto; Maraston, Claudia; Emsellem, Eric; Bershady, Matthew A.; Masters, Karen L.; Yan, Renbin; Bizyaev, Dmitry; Boquien, Médéric; Brownstein, Joel R.; Bundy, Kevin; Drory, Niv; Heckman, Timothy M.; Law, David R.; Roman-Lopes, Alexandre; Pan, Kaike; Stanghellini, Letizia; Thomas, Daniel; Weijmans, Anne-Marie; Westfall, Kyle B. (2016-09-21) - Journal article
    We study the spatially resolved excitation properties of the ionised gas in a sample of 646 galaxies using integral field spectroscopy data from SDSS-IV MaNGA. Making use of Baldwin-Philips-Terlevich diagnostic diagrams ...
  • SDSS IV MaNGA - the spatially resolved transition from star formation to quiescence 

    Belfiore, Francesco; Maiolino, Roberto; Maraston, Claudia; Emsellem, Eric; Bershady, Matthew A.; Masters, Karen L.; Bizyaev, Dmitry; Boquien, Médéric; Brownstein, Joel R.; Bundy, Kevin; Diamond-Stanic, Aleksandar M.; Drory, Niv; Heckman, Timothy M.; Law, David R.; Malanushenko, Olena; Oravetz, Audrey; Pan, Kaike; Roman-Lopes, Alexandre; Thomas, Daniel; Weijmans, Anne-Marie; Westfall, Kyle B.; Yan, Renbin (2017-04) - Journal article
    Using spatially resolved spectroscopy from SDSS-IV MaNGA we have demonstrated that low ionization emission-line regions (LIERs) in local galaxies result from photoionization by hot evolved stars, not active galactic nuclei, ...
  • SDSS-IV MaNGA : a serendipitous observation of a potential gas accretion event 

    Cheung, Edmond; Stark, David V.; Huang, Song; Rubin, Kate H. R.; Lin, Lihwai; Tremonti, Christy; Zhang, Kai; Yan, Renbin; Bizyaev, Dmitry; Boquien, Médéric; Brownstein, Joel R.; Drory, Niv; Gelfand, Joseph D.; Knapen, Johan H.; Maiolino, Roberto; Malanushenko, Olena; Masters, Karen L.; Merrifield, Michael R.; Pace, Zach; Pan, Kaike; Riffel, Rogemar A.; Roman-Lopes, Alexandre; Rujopakarn, Wiphu; Schneider, Donald P.; Stott, John P.; Thomas, Daniel; Weijmans, Anne-Marie (2016-11-30) - Journal article
    The nature of warm, ionized gas outside of galaxies may illuminate several key galaxy evolutionary processes. A serendipitous observation by the MaNGA survey has revealed a large, asymmetric Hα complex with no optical ...
  • SDSS-IV MaNGA : spatially resolved star formation histories in galaxies as a function of galaxy mass and type 

    Goddard, Daniel; Thomas, Daniel; Maraston, Claudia; Westfall, Kyle B.; Etherington, James; Riffel, Rogerio; Mallmann, Nicolas D.; Zheng, Zheng; Argudo-Fernández, Maria; Lian, Jianhui; Bershady, Matthew A.; Bundy, Kevin; Drory, Niv; Law, David R.; Yan, Renbin; Wake, David; Weijmans, Anne-Marie; Bizyaev, Dmitry; Brownstein, Joel R.; Lane, Richard R.; Maiolino, Roberto; Masters, Karen L.; Merrifield, Michael R.; Nitschelm, Christian; Pan, Kaike; Roman-Lopes, Alexandre; Storchi-Bergmann, Thaisa; Schneider, Donald P. (2016-12-31) - Journal article
    We study the internal gradients of stellar population properties within 1.5Re for a representative sample of 721 galaxies with stellar masses ranging between 109M⊙ to 1011.5M⊙ from the SDSS-IV MaNGA IFU survey. Through the ...
  • SDSS-IV MaNGA: faint quenched galaxies I- sample selection and evidence for environmental quenching 

    Penny, Samantha J.; Masters, Karen L.; Weijmans, Anne-Marie; Westfall, Kyle B.; Bershady, Matthew A.; Bundy, Kevin; Drory, Niv; Falcón-Barroso, Jesús; Law, David; Nichol, Robert C.; Thomas, Daniel; Bizyaev, Dmitry; Brownstein, Joel R.; Freischlad, Gordon; Gaulme, Patrick; Grabowski, Katie; Kinemuchi, Karen; Malanushenko, Elena; Malanushenko, Viktor; Oravetz, Daniel; Roman-Lopes, Alexandre; Pan, Kaike; Simmons, Audrey; Wake, David A. (2016-11-11) - Journal article
    Using kinematic maps from the Sloan Digital Sky Survey (SDSS) Mapping Nearby Galaxies at Apache Point Observatory (MaNGA) survey, we reveal that the majority of low-mass quenched galaxies exhibit coherent rotation in their ...
