Connecting CGM enrichment with Lyman alpha emitters at 2.9 < z < 6.7
A. M. Sebastian, E. Ryan-Weber, R. L. Davies +2
We present the results of a blind search for Lyman emitters (LAEs) in three deep archival quasar fields from VLT/MUSE using state-of-the-art detection algorithms. We e…
The Carousel Lens I: A Spectroscopic Survey of the Carousel Lens Field
Jackson H. O'Donnell, Demetrius Y. Williams, Tesla E. Jeltema +18
We present a spectroscopic survey of field galaxies and lensed sources in the vicinity of the strong lensing galaxy cluster known as the Carousel lens at z=0.49. Using both Gemini/…
The SAMI Galaxy Survey: Using Tidal Streams and Shells to Trace the Dynamical Evolution of Massive Galaxies
Tomas H. Rutherford, Jesse van de Sande, Scott M. Croom +14
Slow rotator galaxies are distinct amongst galaxy populations, with simulations suggesting that a mix of minor and major mergers are responsible for their formation. A promising pa…
EMU/GAMA: Radio detected galaxies are more obscured than optically selected galaxies
U. T. Ahmed, A. M. Hopkins, J. Ware +13
We demonstrate the importance of radio selection in probing heavily obscured galaxy populations. We combine Evolutionary Map of the Universe (EMU) Early Science data in the Galaxy…
Searching for the sources of excess extragalactic dispersion of FRBs
Sunil Simha, Khee-Gan Lee, J. Xavier Prochaska +11
The FLIMFLAM survey is collecting spectroscopic data of field galaxies near fast radio burst (FRB) sightlines to constrain key parameters describing the distribution of matter in t…
Investigating the Effect of Galaxy Interactions on AGN Enhancement at
Ekta A. Shah, Jeyhan S. Kartaltepe, Christina T. Magagnoli +30
Galaxy interactions and mergers are thought to play an important role in the evolution of galaxies. Studies in the nearby universe show a higher AGN fraction in interacting and mer…
Disentangling the Cosmic Web Towards FRB 190608
Sunil Simha, Joseph N. Burchett, J. Xavier Prochaska +12
FRB 190608 was detected by ASKAP and localized to a spiral galaxy at in the SDSS footprint. The burst has a large dispersion measure ( )…
Galaxy And Mass Assembly (GAMA): Defining Passive Galaxy Samples and Searching for the UV Upturn
S. Phillipps, S. S. Ali, M. N. Bremer +16
We use data from the GAMA and GALEX surveys to demonstrate that the UV upturn, an unexpected excess of ultraviolet flux from a hot stellar component, seen in the spectra of many ea…
Nowhere to Hide: Radio-faint AGN in the GOODS-N field. I. Initial catalogue and radio properties
J. F. Radcliffe, M. A. Garrett, T. W. B. Muxlow +6
(Abridged) Conventional radio surveys of deep fields ordinarily have arc-second scale resolutions often insufficient to reliably separate radio emission in distant galaxies origina…
Thick turbulent gas disks with magnetocentrifugal winds in active galactic nuclei - Model infrared emission and optical polarization
B. Vollmer, M. Schartmann, L. Burtscher +4
(Abridged) Infrared high-resolution imaging and interferometry have shown that the dust distribution is frequently elongated along the polar direction of an AGN. To explain these f…
The HIX galaxy survey II: HI kinematics of HI eXtreme galaxies
K. A. Lutz, V. A. Kilborn, B. S. Koribalski +6
By analysing a sample of galaxies selected from the HI Parkes All Sky Survey (HIPASS) to contain more than 2.5 times their expected HI content based on their optical properties, we…
Galaxy And Mass Assembly (GAMA): The Consistency of GAMA and WISE Derived Mass-to-Light Ratios
T. Kettlety, J. Hesling, S. Phillipps +11
Recent work has suggested that mid-IR wavelengths are optimal for estimating the mass-to-light ratios of stellar populations and hence the stellar masses of galaxies. We compare st…
Theoretical study of an LAE-CIV absorption pair at z = 5.7
L. A. García, E. Tescari, E. V. Ryan-Weber +1
We present a theoretical model to predict the properties of an observed 5.72 Lyman emitter galaxy - CIV absorption pair separated by 1384 comoving kpc/h. We use the separ…
Low-column density HVC and IVC gas in the halo of the Milky Way
N. Ben Bekhti, P. Richter, M. T. Murphy
Recent studies of the circumgalactic gaseous environment of the Milky Way have concentrated on the distribution, chemical composition, and physical properties of the most massive n…
