SDSS-IV MaNGA: How the stellar populations of passive central galaxies depend on stellar and halo mass
Grecco A. Oyarzun, Kevin Bundy, Kyle B. Westfall +23
We analyze spatially resolved and co-added SDSS-IV MaNGA spectra with signal-to-noise ~100 from 2200 passive central galaxies (z~0.05) to understand how central galaxy assembly dep…
SDSS-IV MaNGA: Radial Gradients in Stellar Population Properties of Early-Type and Late-Type Galaxies
Taniya Parikh, Daniel Thomas, Claudia Maraston +5
We derive ages, metallicities, and individual element abundances of early- and late-type galaxies (ETGs and LTGs) out to 1.5 R. We study a large sample of 1900 galaxies spannin…
The merger-driven evolution of massive early-type galaxies
Carlo Cannarozzo, Carlo Nipoti, Alessandro Sonnenfeld +4
The evolution of the structural and kinematic properties of early-type galaxies (ETGs), their scaling relations, as well as their stellar metallicity and age contain precious infor…
Signatures of stellar accretion in MaNGA early-type galaxies
Grecco A. Oyarzun, Kevin Bundy, Kyle B. Westfall +10
The late assembly of massive galaxies is thought to be dominated by stellar accretion in their outskirts (beyond 2 effective radii Re) due to dry, minor galaxy mergers. We use obse…
SDSS-IV MaNGA: Environmental dependence of the Mgb/<Fe>-sigma_* relation for nearby galaxies
Zheng Zheng, Cheng Li, Shude Mao +13
We use a sample of ~3000 galaxies from the MaNGA MPL-7 internal data release to study the alpha abundance distribution within low-redshift galaxies. We use the Lick index ratio Mgb…
A Giant Protocluster of Galaxies at Redshift 5.7
Linhua Jiang, Jin Wu, Fuyan Bian +14
Galaxy clusters trace the largest structures of the Universe and provide ideal laboratories for studying galaxy evolution and cosmology. Clusters with extended X-ray emission have…
A MegaCam Survey of Outer Halo Satellites. III. Photometric and Structural Parameters
Ricardo R. Munoz, Patrick Cote, Felipe A. Santana +5
We present structural parameters from a wide-field homogeneous imaging survey of Milky Way satellites carried out with the MegaCam imagers on the 3.6m Canada-France-Hawaii Telescop…
A MegaCam Survey of Outer Halo Satellites. I. Description of the Survey
Ricardo R. Munoz, Patrick Cote, Felipe A. Santana +5
We describe a deep, systematic imaging study of satellites in the outer halo of the Milky Way. Our sample consists of 58 stellar overdensities --- i.e., substructures classified as…
SDSS IV MaNGA - sSFR profiles and the slow quenching of discs in green valley galaxies
Francesco Belfiore, Roberto Maiolino, Kevin Bundy +11
We study radial profiles in H equivalent width and specific star formation rate (sSFR) derived from spatially-resolved SDSS-IV MaNGA spectroscopy to gain insight on the physical…
A Magellan M2FS Spectroscopic Survey of Galaxies at 5.5<z<6.8: Program Overview and a Sample of the Brightest Lyman-alpha Emitters
Linhua Jiang, Yue Shen, Fuyan Bian +16
We present a spectroscopic survey of high-redshift, luminous galaxies over four square degrees on the sky, aiming to build a large and homogeneous sample of Ly emitters (LAEs) a…
