Clumpy Galaxies in CANDELS. II. Physical Properties of UV-bright Clumps at
Yicheng Guo, Marc Rafelski, Eric F. Bell +20
Studying giant star-forming clumps in distant galaxies is important to understand galaxy formation and evolution. At present, however, observers and theorists have not reached a co…
The Clustering of High-Redshift (2.9 z 5.1) Quasars in SDSS Stripe 82

We present a measurement of the two-point autocorrelation function of photometrically-selected, high- quasars over 100 deg on the Sloan Digitial Sky Survey Stripe 82…
On the CGM Fundamental Plane: The Halo Mass Dependency of Circumgalactic HI
Rongmon Bordoloi, J. Xavier Prochaska, Jason Tumlinson +3
We analyze the equivalent widths of HI Ly- () absorption from the inner (R < 160 kpc) circumgalactic medium (CGM) of 85 galaxies at with stellar masses …
SDSS-IV MaNGA: What Shapes The Distribution Of Metals In Galaxies? Exploring The Roles Of The Local Gas Fraction And Escape Velocity
J. K. Barrera-Ballesteros, T. Heckman, S. F. Sanchez +6
We determine the local metallicity of the ionized gas for more than star forming regions (spaxels) located in 1023 nearby galaxies included in the SDSS-IV MaNGA IF…
No sign of strong molecular gas outflow in an infrared-bright dust-obscured galaxy with strong ionized-gas outflow
Yoshiki Toba, Shinya Komugi, Tohru Nagao +4
We report the discovery of an infrared (IR)-bright dust-obscured galaxy (DOG) that shows a strong ionized-gas outflow but no significant molecular gas outflow. Based on detail anal…
SDSS-IV MANGA: Spatially Resolved Star Formation Main Sequence and LI(N)ER Sequence
B. C. Hsieh, Lihwai Lin, J. H. Lin +17
We present our study on the spatially resolved H_alpha and M_star relation for 536 star-forming and 424 quiescent galaxies taken from the MaNGA survey. We show that the star format…
The supermassive black hole coincident with the luminous transient ASASSN-15lh
T. Krühler, M. Fraser, G. Leloudas +11
The progenitors of astronomical transients are linked to a specific stellar population and galactic environment, and observing their host galaxies hence constrains the physical nat…
SMHASH: Anatomy of the Orphan Stream using RR Lyrae stars
David Hendel, Victoria Scowcroft, Kathryn V. Johnston +30
Stellar tidal streams provide an opportunity to study the motion and structure of the disrupting galaxy as well as the gravitational potential of its host. Streams around the Milky…
Serendipitous discovery of an optical emission line jet in NGC\,232
C. Lopez-Coba, S. F. Sanchez, I. Cruz-Gonzalez +9
We report the detection of a highly collimated linear emission-line structure in the spiral galaxy NGC\,232 through the use of integral field spectroscopy data from the All-weather…
Global Properties of M31's Stellar Halo from the SPLASH Survey: III. Measuring the Stellar Velocity Dispersion Profile
Karoline M. Gilbert, Erik Tollerud, Rachael L. Beaton +7
We present the velocity dispersion of red giant branch (RGB) stars in M31's halo, derived by modeling the line of sight velocity distribution of over 5000 stars in 50 fields spread…
Galactic Surveys in the Gaia Era
Rosemary F. G. Wyse
The final astrometric data from the Gaia mission will transform our view of the stellar content of the Galaxy, particularly when complemented with spectroscopic surveys providing s…
Star formation is boosted (and quenched) from the inside out: radial star formation profiles from MaNGA
Sara L. Ellison, Sebastian F. Sanchez, Hector Ibarra-Medel +3
The tight correlation between total galaxy stellar mass and star formation rate (SFR) has become known as the star forming main sequence. Using ~487,000 spaxels from galaxies obser…
Where are All the Gas-Bearing Local Dwarf Galaxies? Quantifying Possible Impacts of Reionization
Erik J. Tollerud, J. E. G. Peek
We present an approach for comparing the detections and non-detections of Local Group (LG) dwarf galaxies in large HI surveys to the predictions of a suite of n-body simulations of…
Observational Constraints on Correlated Star Formation and Active Galactic Nuclei in Late-Stage Galaxy Mergers
R. Scott Barrows, Julia M. Comerford, Nadia L. Zakamska +1
