The most ancient spiral galaxy: a 2.6-Gyr-old disk with a tranquil velocity field
Tiantian Yuan, Johan Richard, Anshu Gupta +7
We report an integral-field spectroscopic (IFS) observation of a gravitationally lensed spiral galaxy A1689B11 at redshift . It is the most ancient spiral galaxy discovered…
The SAMI Galaxy Survey: Global stellar populations on the size-mass plane
Nicholas Scott, S. Brough, Scott M. Croom +20
We present an analysis of the global stellar populations of galaxies in the SAMI Galaxy Survey. Our sample consists of 1319 galaxies spanning four orders of magnitude in stellar ma…
The Chemical Evolution Carousel of Spiral Galaxies: Azimuthal Variations of Oxygen Abundance in NGC1365
I-Ting Ho, Mark Seibert, Sharon E. Meidt +9
The spatial distribution of oxygen in the interstellar medium of galaxies is the key to understanding how efficiently metals that are synthesized in massive stars can be redistribu…
Probing the Physics of Narrow Line Regions in Active Galaxies IV: Full data release of The Siding Spring Southern Seyfert Spectroscopic Snapshot Survey (S7)
Adam D. Thomas, Michael A. Dopita, Prajval Shastri +15
We present the second and final data release of the Siding Spring Southern Seyfert Spectroscopic Snapshot Survey (S7). Data are presented for 63 new galaxies not included in the fi…
The SAMI Galaxy Survey: Data Release One with Emission-line Physics Value-Added Products
Andrew W. Green, Scott M. Croom, Nicholas Scott +48
We present the first major release of data from the SAMI Galaxy Survey. This data release focuses on the emission-line physics of galaxies. Data Release One includes data for 772 g…
The Origins of [CII] Emission in Local Star-forming Galaxies
Kevin Croxall, J. D. T. Smith, Eric Pellegrini +17
The [CII] 158um fine-structure line is the brightest emission line observed in local star-forming galaxies. As a major coolant of the gas-phase interstellar medium, [CII] balances…
The SAMI Galaxy Survey: Disk-halo interactions in radio-selected star-forming galaxies
S. K. Leslie, J. J. Bryant, I. -T. Ho +20
In this paper, we compare the radio emission at 1.4 GHz with optical outflow signatures of edge-on galaxies. We report observations of six edge-on star-forming galaxies in the Sydn…
Dissecting Galaxies: Separating Star Formation, Shock Excitation and AGN Activity in the Central Region of NGC 613
Rebecca L. Davies, Brent Groves, Lisa J. Kewley +13
The most rapidly evolving regions of galaxies often display complex optical spectra with emission lines excited by massive stars, shocks and accretion onto supermassive black holes…
Attenuation modified by DIG and dust as seen in M31
Neven Tomicic, Kathryn Kreckel, Brent Groves +5
The spatial distribution of dust in galaxies affects the global attenuation, and hence inferred properties, of galaxies. We trace the spatial distribution of dust in five fields (a…
The Dust Attenuation of Star-forming Galaxies at and Beyond: New Insights from ALMA Observations
Yoshinobu Fudamoto, Pascal A. Oesch, Eva Schinnerer +10
We present results on the dust attenuation of galaxies at redshift by studying the relationship between the UV spectral slope () and the infrared excess (IRX;…
The Survey of Lines in M31 (SLIM): The Drivers of the [CII]/TIR Variation
Maria Julia Kapala, Brent Groves, Karin Sandstrom +7
The ratio of the [CII] 158m emission line over the total infrared emission (TIR) is often used as a proxy for the photoelectric (PE) heating efficiency () of the f…
The SAMI Galaxy Survey: a new method to estimate molecular gas surface densities from star formation rates
Christoph Federrath, Diane M. Salim, Anne M. Medling +16
Stars form in cold molecular clouds. However, molecular gas is difficult to observe because the most abundant molecule (H2) lacks a permanent dipole moment. Rotational transitions…
