Chemical Abundances of Planetary Nebulae in the Substructures of M31 -- II. The Extended Sample and A Comparison Study with the Outer-disk Group

Xuan Fang, Ruben Garcia-Benito, Martin A. Guerrero +7

We report deep spectroscopy of ten planetary nebulae (PNe) in the Andromeda Galaxy (M31) using the 10.4m GTC. Our targets reside in different regions of M31, including halo streams…

Galaxy And Mass Assembly (GAMA): Blue spheroids within 87 Mpc

Smriti Mahajan, Michael J. Drinkwater, S. Driver +7

In this paper we test if nearby blue spheroid (BSphs) galaxies may become the progenitors of star-forming spiral galaxies or passively-evolving elliptical galaxies. Our sample comp…

IFU spectroscopy of southern PN VI: The extraordinary chemo-dynamics of Hen 2-111

M. A. Dopita, A. Ali, A. I. Karakas +3

In this paper we present integral field spectroscopy of the extraordinary Type I bipolar planetary nebula Hen 2-111. In the lobes we map fast moving knots of material with [N II]$λ…

Group quenching and galactic conformity at low redshift

M. Treyer, K. Kraljic, S. Arnouts +13

We quantify the quenching impact of the group environment using the spectroscopic survey Galaxy and Mass Assembly (GAMA) to z=0.2. The fraction of red (quiescent) galaxies, whether…

Photometric redshifts for the next generation of deep radio continuum surveys - II. Gaussian processes and hybrid estimates

Kenneth J Duncan, Matt J. Jarvis, Michael J. I. Brown +1

Building on the first paper in this series (Duncan et al. 2018), we present a study investigating the performance of Gaussian process photometric redshift (photo-z) estimates for g…

Galaxy And Mass Assembly (GAMA): the G02 field, Herschel-ATLAS target selection and Data Release 3

I. K. Baldry, J. Liske, M. J. I. Brown +39

We describe data release 3 (DR3) of the Galaxy And Mass Assembly (GAMA) survey. The GAMA survey is a spectroscopic redshift and multi-wavelength photometric survey in three equator…
