Wed 15 May, 2019 @14:15 PM, level 7, David Caro Building Dr Kim-Vy Tran, UNSW Email:  kimvy.tran[at]gmail.com Abstract ZFOURGE and MOSEL are deep observational surveys that track how galaxies assemble over cosmic time. ZFOURGE identifies approximately 70,000 objects up to redshifts of z~7 using a custom set of near-infrared imaging filters that provide high precision photometric redshifts. MOSEL targets emergent galaxies from ZFOURGE for …

Mon 13th May, 2019 @14:15 PM, level 6, David Caro Building Dr Koki Kakiichi, University College London Email: k.kakiichi@ucl.ac.uk Abstract Study of reionization is now experiencing a surge of new insights, but the long-standing problem 'what reionized the universe' still remains unsolved. Hubble observations have placed a now-commonly-held view that the intrinsically faint galaxies are responsible for driving the reionization process, but with a …

Wed 8th May 2019 @14:15 PM, level 7, David Caro Building Dr Emma Kerr RMIT Email:  emma.kerr[at]rmit.edu.au Abstract The problem posed by space debris has been internationally recognised and many different methods tackling both mitigation and remediation have been proposed. One fundamental challenge though is accurate tracking and position prediction of objects in orbit. Beyond improving technology, the only method for tackling this challenge …

Fri 3rd May, 2019 @15:15 PM, level 7, David Caro Building Professor Romeel Davé, University of Edinburgh Email:  rad@roe.ac.uk Abstract The growth of black holes and their role in quenching massive galaxies is a key unsolved problem in galaxy formation. I present a new suite of cosmological hydrodynamic simulations called Simba, which builds on our successful Mufasa simulations to include a novel torque-limited …

Wed 1st May, 2019 @14:15 PM, level 7, David Caro Building Dr Paul Lasky, Monash University Email:  paul.lasky@monash.edu Abstract Gravitational-wave astronomy is now a reality. In the first two observing runs of Advanced LIGO and Virgo, there were ten detected black hole collisions, and one spectacular multimessenger detection of a binary neutron star merger. But what is next for this burgeoning field …

Wed 17 April, 2019 @14:15 PM, level 7, David Caro Building Dr Rossana Ruggeri, Swinburne University Email:  rruggeri[at]swin.edu.au Abstract With the aid of millions of galaxies, cosmology, as a data driven discipline, investigates the physics just after the Big-Bang, when the seeds of anisotropies ( later becoming galaxies through gravity ) were created and the effect of dark energy driving the evolution of the …

Mon 1 April 2019 @14:15 PM, level 7, David Caro Building Dr Sarah Sweet Swinburne University Email:  sarah[at]sarahsweet.com.au   Abstract How do galaxies evolve from the compact, red nuggets; clumpy, turbulent disks; and complex merging systems of the early Universe to the familiar Hubble types we see today? Their evolution is intimately linked with the environmental conditions and structure of the Universe since cosmic noon. …

Wed 27 March 2019 @14:15 PM, level 7, David Caro Building Dr Amelia Fraser-McKelvie, University of Nottingham Email:  amelia.fraser-mckelvie[at]nottingham.ac.uk   Abstract Most galaxies consist of a dispersion-dominated bulge region and a regularly rotating disk. These components have built up their mass separately through different processes, yet are evolving together. It has become commonplace to separate the light from bulge and disk regions to better understand …
