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_…
Spectral Evolution in High Redshift Quasars from the Final BOSS Sample
Trey W. Jensen, M. Vivek, Kyle S. Dawson +17
We report on the diversity in quasar spectra from the Baryon Oscillation Spectroscopic Survey. After filtering the spectra to mitigate selection effects and Malmquist bias associat…
Searching for Binary Supermassive Black Holes via Variable Broad Emission Line Shifts: Low Binary Fraction
Lile Wang, Jenny E. Greene, Wenhua Ju +3
Supermassive black hole binaries (SMBHs) are expected to result from galaxy mergers, and thus are natural byproducts (and probes) of hierarchical structure formation in the Univers…
Photometric properties of intermediate redshift Type Ia Supernovae observed by SDSS-II Supernova Survey
Naohiro Takanashi, Mamoru Doi, Naoki Yasuda +5
We have analyzed multi-band light curves of 328 intermediate redshift (0.05 <= z < 0.24) type Ia supernovae (SNe Ia) observed by the Sloan Digital Sky Survey-II Supernova Survey (S…
The Rest-Frame Optical Morphology of Emission Line Galaxies at 2 < z < 3: Evidence for Inside-Out Formation in Low-Mass Galaxies
Alex Hagen, Nicholas A. Bond, Robin Ciardullo +6
We compare the rest-frame ultraviolet and rest-frame optical morphologies of 2 < z < 3 star-forming galaxies in the GOODS-S field using Hubble Space Telescope WFC3 and ACS images f…
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 Mean Metal-line Absorption Spectrum of DLAs in BOSS
Lluís Mas-Ribas, Jordi Miralda-Escudé, Ignasi Pérez-Ràfols +6
We study the mean absorption spectrum of the Damped Lyman alpha population at by stacking normalized, rest-frame shifted spectra of DLAs from the DR12 of…
Extremely Red Quasars in BOSS
Fred Hamann, Nadia L. Zakamska, Nicholas Ross +11
Red quasars are candidate young objects in an early transition stage of massive galaxy evolution. Our team recently discovered a population of extremely red quasars (ERQs) in the B…
The Sloan Digital Sky Survey Quasar Catalog: twelfth data release
Isabelle Pâris, Patrick Petitjean, Nicholas P. Ross +43
We present the Data Release 12 Quasar catalog (DR12Q) from the Baryon Oscillation Spectroscopic Survey (BOSS) of the SDSS-III. This catalog includes all SDSS-III/BOSS objects that…
Red giants observed by CoRoT and APOGEE: The evolution of the Milky Way's radial metallicity gradient
F. Anders, C. Chiappini, I. Minchev +21
Using combined asteroseismic and spectroscopic observations of 418 red-giant stars close to the Galactic disc plane (6 kpc kpc, kpc), w…
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…
Disentangling AGN and Star Formation Activity at High Redshift Using Hubble Space Telescope Grism Spectroscopy
Joanna S. Bridge, Gregory R. Zeimann, Jonathan R. Trump +4
Differentiating between active galactic nuclei (AGN) activity and star formation in z ~ 2 galaxies is difficult because traditional methods, such as line ratio diagnostics, change…
The Composite Spectrum of BOSS Quasars Selected for Studies of the Lyman-alpha Forest
David W. Harris, Trey W. Jensen, Nao Suzuki +12
The Baryon Oscillation Spectroscopic Survey (BOSS) has collected more than 150,000 quasar spectra since 2009. Using this unprecedented sample, we create a com…
