Testing the Universality of the Stellar IMF with Chandra and HST
D. A. Coulter, B. D. Lehmer, R. T. Eufrasio +8
The stellar initial mass function (IMF), which is often assumed to be universal across unresolved stellar populations, has recently been suggested to be "bottom-heavy" for massive…
SDSS IV MaNGA: Deep observations of extra-planar, diffuse ionized gas around late-type galaxies from stacked IFU spectra

We have conducted a study of extra-planar diffuse ionized gas using the first year data from the MaNGA IFU survey. We have stacked spectra from 49 edge-on, late-type galaxies as a…
Giant Metrewave Radio Telescope detection of associated HI 21cm absorption at towards TXS1954+513

We have used the 610 MHz receivers of the Giant Metrewave Radio Telescope (GMRT) to detect associated HI 21cm absorption from the blazar TXS1954+513. The GMRT HI 21cm…
Chemical enrichment of stars due to accretion from ISM during the Galaxy's assembly
Sijing Shen, Girish Kulkarni, Piero Madau +1
Using the Eris zoom-in cosmological simulation of assembly of a Milky Way analog, we study chemical enrichment of stars due to accretion of metal-enriched gas from the interstellar…
Constraining C iii] Emission in a Sample of Five Luminous z = 5.7 Galaxies
Jiani Ding, Zheng Cai, Xiaohui Fan +6
Recent observations have suggested that the CIII] emission lines could be alternative diagnostic lines for galaxies in the reionization epoch. We use the F128N na…
The Initial Mass Function in the Nearest Strong Lenses from SNELLS: Assessing the Consistency of Lensing, Dynamical, and Spectroscopic Constraints
Andrew B. Newman, Russell J. Smith, Charlie Conroy +2
We present new observations of the three nearest early-type galaxy (ETG) strong lenses discovered in the SINFONI Nearby Elliptical Lens Locator Survey (SNELLS). Based on their lens…
The Stellar Initial Mass Function in Early-Type Galaxies From Absorption Line Spectroscopy. IV. A Super-Salpeter IMF in the center of NGC 1407 from Non-Parametric Models
Charlie Conroy, Pieter van Dokkum, Alexa Villaume
It is now well-established that the stellar initial mass function (IMF) can be determined from the absorption line spectra of old stellar systems, and this has been used to measure…
The HDUV Survey: Six Lyman Continuum Emitter Candidates at z~2 Revealed by HST UV Imaging
R. P. Naidu, P. A. Oesch, N. Reddy +14
We present six galaxies at z~2 that show evidence of Lyman continuum (LyC) emission based on the newly acquired UV imaging of the Hubble Deep UV legacy survey (HDUV) conducted with…
THE NEXT GENERATION VIRGO CLUSTER SURVEY. XIV. Shell feature early-type dwarf galaxies in the Virgo cluster
Sanjaya Paudel, Rory Smith, Pierre-Alain Duc +15
The Next Generation Virgo Cluster Survey is a deep (with a detection limit = 29~mag~arcsec in the band) optical panchromatic survey targeting the Virgo cluste…
The growth of the central region by acquisition of counter-rotating gas in star-forming galaxies
Yan-Mei Chen, Yong Shi, Christy A. Tremonti +29
Galaxies grow through both internal and external processes. In about 10% of nearby red galaxies with little star formation, gas and stars are counter-rotating, demonstrating the im…
The Stellar Initial Mass Function in Early-Type Galaxies from Absorption Line Spectroscopy. III. Radial Gradients
Pieter van Dokkum, Charlie Conroy, Alexa Villaume +2
There is good evidence that the centers of massive early-type galaxies have a bottom-heavy stellar initial mass function (IMF) compared to the IMF of the Milky Way. Here we study t…
The Nature of Massive Transition Galaxies in CANDELS, GAMA, and Cosmological Simulations
Viraj Pandya, Ryan Brennan, Rachel S. Somerville +25
We explore observational and theoretical constraints on how galaxies might transition between the "star-forming main sequence" (SFMS) and varying "degrees of quiescence" out to $z=…
Attenuation from the optical to the extreme ultraviolet by dust associated with broad absorption line quasars: the driving force for outflows
C. Martin Gaskell, Jake J. M. Gill, Japneet Singh
We derive a mean attenuation curve out to the rest-frame extreme ultraviolet (EUV) for 'BAL dust' - the dust causing the additional extinction of active galactic nuclei (AGNs) with…
The Next Generation Virgo Cluster Survey (NGVS). XXIV. The Red Sequence to 10 L and Comparisons with Galaxy Formation Models
Joel C. Roediger, Laura Ferrarese, Patrick Côté +22
We use deep optical photometry from the Next Generation Virgo Cluster Survey [NGVS] to investigate the color-magnitude diagram for the galaxies inhabiting the core of this cluster.…
