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…
Follow up of GW170817 and its electromagnetic counterpart by Australian-led observing programs
I. Andreoni, K. Ackley, J. Cooke +122
The discovery of the first electromagnetic counterpart to a gravitational wave signal has generated follow-up observations by over 50 facilities world-wide, ushering in the new era…
A Radio Counterpart to a Neutron Star Merger
G. Hallinan, A. Corsi, K. P. Mooley +30
Gravitational waves have been detected from a binary neutron star merger event, GW170817. The detection of electromagnetic radiation from the same source has shown that the merger…
In search of cool flow accretion onto galaxies where does the disk gas end?
Joss Bland-Hawthorn, Phil Maloney, Alex Stephens +2
The processes taking place in the outermost reaches of spiral disks (the 'proto-disk') are intimately connected to the build-up of mass and angular momentum in galaxies. The thinne…
Spatial Clustering of Dark Matter Halos: Secondary Bias, Neighbor Bias, and the Influence of Massive Neighbors on Halo Properties
Andrés N. Salcedo, Ariyeh H. Maller, Andreas A. Berlind +5
We explore the phenomenon commonly known as halo assembly bias, whereby dark matter halos of the same mass are found to be more or less clustered when a second halo property is con…
