SDSS IV MaNGA: Deep observations of extra-planar, diffuse ionized gas around late-type galaxies from stacked IFU spectra
A. Jones, G. Kauffmann, R. D'Souza +16
We have conducted a study of extra-planar diffuse ionized gas using the first year data from the MaNGA IFU survey. We have stacked spectra from 49 edge-on, late-type galaxies as a…
SDSS-IV MaNGA: Spatially resolved star formation histories in galaxies as a function of galaxy mass and type
Daniel Goddard, Daniel Thomas, Claudia Maraston +25
We study the internal gradients of stellar population properties within for a representative sample of 721 galaxies with stellar masses ranging between $10^{9}\;M_…
SDSS-IV MaNGA: stellar population gradients as a function of galaxy environment
Daniel Goddard, Daniel Thomas, Claudia Maraston +23
We study the internal radial gradients of stellar population properties within and analyse the impact of galaxy environment. We use a representative sample of 721…
SDSS-IV MaNGA: Bulge-Disc Decomposition of IFU Datacubes (BUDDI)
Evelyn J. Johnston, Boris Haeussler, Alfonso Aragon-Salamanca +12
With the availability of large integral-field unit (IFU) spectral surveys of nearby galaxies, there is now the potential to extract spectral information from across the bulges and…
SDSS-IV MaNGA: Properties of galaxies with kinematically decoupled stellar and gaseous components
Yifei Jin, Yanmei Chen, Yong Shi +30
We study the properties of 66 galaxies with kinematically misaligned gas and stars from MaNGA survey. The fraction of kinematically misaligned galaxies varies with galaxy physical…
The growth of the central region by acquisition of counter-rotating gas in star-forming galaxies
Yan-Mei Chen, Yong Shi, Christy A. Tremonti +29
Galaxies grow through both internal and external processes. In about 10% of nearby red galaxies with little star formation, gas and stars are counter-rotating, demonstrating the im…
SDSS-IV MaNGA: A serendipitous observation of a potential gas accretion event
Edmond Cheung, David V. Stark, Song Huang +24
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,…
The quenching time scale and quenching rate of galaxies
Jianhui Lian, Renbin Yan, Kai Zhang +1
The average star formation rate (SFR) in galaxies has been declining since redshift of 2. A fraction of galaxies quench and become quiescent. We constrain two key properties of the…
SDSS IV MaNGA - The spatially resolved transition from star formation to quiescence
Francesco Belfiore, Roberto Maiolino, Claudia Maraston +19
Using spatially resolved spectroscopy from SDSS-IV MaNGA we have demonstrated that low ionisation emission line regions (LIERs) in local galaxies result from photoionisation by hot…
SDSS-IV MaNGA IFS Galaxy Survey --- Survey Design, Execution, and Initial Data Quality
Renbin Yan, Kevin Bundy, David R. Law +47
The MaNGA Survey (Mapping Nearby Galaxies at Apache Point Observatory) is one of three core programs in the Sloan Digital Sky Survey IV. It is obtaining integral field spectroscopy…
Suppressing star formation in quiescent galaxies with supermassive black hole winds
Edmond Cheung, Kevin Bundy, Michele Cappellari +22
Quiescent galaxies with little or no ongoing star formation dominate the galaxy population above , where their numbers have increased by a fac…
SDSS IV MaNGA - Spatially resolved diagnostic diagrams: A proof that many galaxies are LIERs
Francesco Belfiore, Roberto Maiolino, Claudia Maraston +17
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 Baldwi…
Stellar Mass--Gas-phase Metallicity Relation at : A Power Law with Increasing Scatter toward the Low-mass Regime
Yicheng Guo, David C. Koo, Yu Lu +21
We present the stellar mass ()--gas-phase metallicity relation (MZR) and its scatter at intermediate redshifts () for 1381 field galaxies collected from de…
