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: energy sources of the turbulent velocity dispersion in spatially-resolved local star-forming galaxies
Luwenjia Zhou, Christoph Federrath, Tiantian Yuan +16
We investigate the energy sources of random turbulent motions of ionised gas from H emission in eight local star-forming galaxies from the Sydney-AAO Multi-object Integral field…
Survival of Massive Star-forming Galaxies in Cluster Cores Drives Gas-Phase Metallicity Gradients : The Effects of Ram Pressure Stripping
Anshu Gupta, Tiantian Yuan, Davide Martizzi +2
Recent observations of galaxies in a cluster at z=0.35 show that their integrated gas-phase metallicities increase with decreasing cluster-centric distance. To test if ram pressure…
ZFIRE: Using H equivalent widths to investigate the in situ initial mass function at z~2
Themiya Nanayakkara, Karl Glazebrook, Glenn G. Kacprzak +10
We use the ZFIRE survey (http://zfire.swinburne.edu.au) to investigate the high mass slope of the initial mass function (IMF) for a mass-complete (log10(M/M)~9.3) sampl…
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…
ZFIRE: The Evolution of the Stellar Mass Tully-Fisher Relation to Redshift 2.0 < Z < 2.5 with MOSFIRE
Caroline M. S. Straatman, Karl Glazebrook, Glenn G. Kacprzak +8
Using observations made with MOSFIRE on Keck I as part of the ZFIRE survey, we present the stellar mass Tully-Fisher relation at 2.0 < z < 2.5. The sample was drawn from a stellar…
