Census of blue stars in SDSS DR8
Samantha Scibelli, Heidi Jo Newberg, Jeffrey L. Carlin +1
We present a census of the 12,060 spectra of blue objects () in the Sloan Digital Sky Survey (SDSS) Data Release 8 (DR8). As part of the data release, all of the spe…
Small-scale Properties of Atomic Gas in Extended Disks of Galaxies
Sanchayeeta Borthakur, Emmanuel Momjian, Timothy M. Heckman +4
We present high-resolution HI 21 cm observations with the Karl G. Jansky Very Large Array (VLA) for three HI rich galaxies in absorption against radio quasars. Our sample contains…
Fixing the Reference Frame for PPMXL Proper Motions Using Extragalactic Sources
Kathleen Grabowski, Jeffrey L. Carlin, Heidi Jo Newberg +14
We quantify and correct systematic errors in PPMXL proper motions using extragalactic sources from the first two LAMOST data releases and the Veron-Cetty & Veron Catalog of Quasars…
The dust, nebular emission and dependence on QSO radio properties of the associated Mg II absorption line systems
Pushpa Khare, Daniel Vanden Berk, Hadi Rahmani +1
We studied dust reddening and [O II] emission in 1730 Mg II associated absorption systems (AAS; relative velocity with respect to QSOs, < 3000 km/s; in units of velocity of light,…
The Dependence of C IV Broad Absorption Line Properties on Accompanying Si IV and Al III Absorption: Relating Quasar-Wind Ionization Levels, Kinematics, and Column Densities
N. Filiz Ak, W. N. Brandt, P. B. Hall +10
We consider how the profile and multi-year variability properties of a large sample of C IV Broad Absorption Line (BAL) troughs change when BALs from Si IV and/or Al III are presen…
Line Overlap and Self-Shielding of Molecular Hydrogen in Galaxies
Nickolay Y. Gnedin, Bruce T. Draine
The effect of line overlap in the Lyman and Werner bands, often ignored in galactic studies of the atomic-to-molecular transition, greatly enhances molecular hydrogen self-shieldin…
Preventing Star Formation in Early-Type Galaxies with Late-Time Stellar Heating
Charlie Conroy, Pieter van Dokkum, Andrey Kravtsov
We revisit previous suggestions that the heating provided by the winds of dying low-mass stars plays an important role in preventing star formation in quiescent galaxies. At the en…
The Sloan Digital Sky Survey Stripe 82 Imaging Data: Depth-Optimized Co-adds Over 300 Deg^2 in Five Filters
Linhua Jiang, Xiaohui Fan, Fuyan Bian +9
We present and release co-added images of the Sloan Digital Sky Survey (SDSS) Stripe 82. Stripe 82 covers an area of 300 deg^2 on the Celestial Equator, and has been repeatedly sca…
The Vertical Metallicity Gradient of the Milky Way Disk: Transitions in [a/Fe] Populations
Katharine J. Schlesinger, Jennifer A. Johnson, Constance M. Rockosi +10
Using G dwarfs from the Sloan Extension for Galactic Understanding and Exploration (SEGUE) survey, we have determined a vertical metallicity gradient over a large volume of the Mil…
Near Infrared Spectra and Intrinsic Luminosities of Candidate Type II Quasars at 2 < z < 3.4
Jenny E Greene, Rachael Alexandroff, Michael A Strauss +10
We present JHK near-infrared (NIR) spectroscopy of 25 candidate Type II quasars selected from the Sloan Digital Sky Survey, using Triplespec on the Apache Point Observatory 3.5m te…
On the interplay between star formation and feedback in galaxy formation simulations
Oscar Agertz, Andrey V. Kravtsov
We investigate the star formation-feedback cycle in cosmological galaxy formation simulations, focusing on progenitors of Milky Way (MW)-sized galaxies. We find that in order to re…
A connection between extremely strong Damped Lyman-alpha Systems and Lyman-alpha Emitting Galaxies at small impact parameters
P. Noterdaeme, P. Petitjean, I. Paris +5
We present a study of ~100 high redshift (z~2-4) extremely strong damped Lyman-alpha systems (ESDLA, with N(HI)>0.5x10^22 cm^-2) detected in quasar spectra from the Baryon Oscillat…
The Rest-Frame Submillimeter Spectrum of High-Redshift, Dusty, Star-Forming Galaxies
J. S. Spilker, D. P. Marrone, J. E. Aguirre +28
We present the average rest-frame spectrum of high-redshift dusty, star-forming galaxies from 250-770GHz. This spectrum was constructed by stacking ALMA 3mm spectra of 22 such sour…
The First Hypervelocity Star from the LAMOST Survey
Zheng Zheng, Jeffrey L. Carlin, Timothy C. Beers +10
We report the first hypervelocity star (HVS) discovered from the LAMOST spectroscopic survey. It is a B-type star with a heliocentric radial velocity about 620 km/s, which projects…
Emergence of the Kennicutt-Schmidt Relation from the Small-Scale SFR-Density Relation
Nickolay Y. Gnedin, Elizabeth J. Tasker, Yusuke Fujimoto
We use simulations of isolated galaxies with a few parsec resolution to explore the connection between the small-scale star formation rate - gas density relation and the induced la…
