Mon 25th March, 2019 @14:15 PM, level 7, David Caro Building Dr Benedetta Vulcani, INAF - Osservatorio Astronomico di Padova Email:  benedetta.vulcani[at]inaf.it Abstract Studying galaxies in transition in the different environments give important clues on galaxy evolution. I will present different methods to select galaxies in transition, showing how different approaches can reveal different pathways to quenching. - Transition galaxies can be identified as outliers …

Mon 18 March 2019 @14:15 PM, level 7, David Caro Building Prof. Ian Jones University of Southampton, UK Email:  d.i.jones[at]soton.ac.uk Abstract In this talk I will describe the physics that determines the spin evolution of millisecond magnetars, early in their lives. The results have implications for their gravitational wave emission, and for the distributions of spins and magnetic field geometries observed in the Galactic …

Wed 6 March, 2019 @12:00 PM, level 7, David Caro Building Dr Matthew Baring, Rice University Email:  baring[at]rice.edu Abstract Magnetars are young neutron stars with high surface magnetic fields, exceeding around 10 TeraGauss. Pulsed, non-thermal quiescent X-ray emission extending between 10 keV to >150 keV has been observed in about 10 magnetars by RXTE, INTEGRAL, Suzaku, NuSTAR and Fermi-GBM. This talk describes a model for the generation of …

Thurs 28 Feb, 2019 @12:00 PM, level 7, David Caro Building Dr Natasha Hurley-Walker, ICRAR Email:  nhw[at]icrar.org Abstract Using images from the GaLactic and Extragalactic All-sky Murchison Widefield Array (GLEAM; MWA) survey, I have discovered 27 new supernova remnants (SNRs) via their non-thermal emission at low radio frequencies. Some of these are quite unusual objects with very low surface brightness, while others were simply …

Wed 27 February 2019 @12:00 PM, level 7, David Caro Building Prof. Ilya Mandel Monash University Email:  ilya.mandel[at]monash.edu   Abstract The first detections of gravitational waves from compact-object mergers have opened up new opportunities and challenges in astrophysics. I will describe ongoing efforts to extract the astrophysical evolution of massive stellar binaries from observations of gravitational waves emitted during mergers of the stellar remnants.  

Mon 25 February, 2019 @14:15 PM, level 7, David Caro Building Dr Gemma Anderson, ICRAR, Curtin University Email:  gemma.anderson[at]curtin.edu.au Abstract The first neutron star gravitational wave merger has been detected and Australia is primed to take the lead in locating their radio afterglows. However, the positional uncertainties make fast localisation of the electromagnetic counterpart extremely difficult. In order to address this concern, I use …

Thurs 14 February 2019 @12:00 PM, level 7, David Caro Building Dr Christopher Berrry Northwestern Email:  christopher.berry[at]northwestern.edu Abstract The gravitational waves observed by LIGO and Virgo encode unique information about their sources. I will explain how we go from the observed signal to making inferences about the source's parameters, such as a black hole's mass and spin. These properties are an insight into the processes …

Wed 13 February, 2019 @12:00 PM, level 7, David Caro Building Assistant Professor Sebastiano Cantalupo, ETH Zurich Email:  cantalupo[at]phys.ethz.ch Abstract Our standard cosmological model predicts that most of the matter in the universe is distributed into a network of filaments - the Cosmic Web - in which galaxies form and evolve. Because most of this material is too diffuse to form stars, its direct …
