Wednesday 08 Sep 2021 @ 10:00 a.m., Zoom Grace Olivier, Ohio State University; Email: olivier.15[at]buckeyemail.osu.edu Abstract Massive stars contribute incredible amounts of energy to their surroundings across a variety of environments in the universe. Before their exciting deaths, massive stars produce feedback through a number of mechanisms that are frequently used in subgrid physics models in galaxy simulations to create realistic galaxies. Observations …

Wednesday 25 Aug 2021 @ 10:00 a.m., Zoom Kshitij Aggarwal, West Virginia University; Email: ka0064[at]mix.wvu.edu Abstract Fast Radio Bursts (FRBs) are millisecond-duration, transient sources of extragalactic origin. In this talk, I will describe an end-to-end search and analysis software suite to study FRBs. All of these tools are python-based, user-friendly, robust, and have been tested rigorously. I will start with Your (Your Unified …

Wednesday 18 Aug 2021 @ 12:00 p.m., Zoom Dr Hyunbae Park, Kavli Institute for the Physics and Mathematics of the Universe; Email: hcosmosb[at]g.ecc.u-tokyo.ac.jp Abstract We expect neutral hydrogen gas in the intergalactic space to have scattered a significant portion of Lyα emission from star-forming galaxies during the reionization era. Thus, the Lyα line strength of high-z galaxies is considered a promising probe of …

Wednesday 11 Aug 2021 @ 12:00 p.m., Zoom Dr Janakee Raste, Tata Institue of Fundamental Research; Email: -%%janakee[at]theory.tifr.res.in Abstract Most ongoing experiments targetting the fluctuating 21-cm cosmological signal aim to look for the signal at redshifts well above 6. This strategy is motivated by the traditional assumption that reionization ends at z >~ 6. However, recent constraints from Lyman-α and CMB data prefer …

Wednesday 04 Aug 2021 @ 12:00 p.m., David Caro building, Level 2, Hercus Theatre (+Zoom) Dr Rebecca Davies, Swinburne University; Email: rdavies[at]swinburne.edu.au Abstract Abstract: Outflows are likely to play an important role in shaping the growth and evolution of galaxies, especially at the peak epoch of star formation (z~1-3) where outflows are ubiquitous. Detailed measurements are now required to better constrain feedback models …

Wednesday 28 Jul 2021 @ 12:00 p.m., David Caro building, Level 2, Hercus Theatre (+Zoom) Dr Manodeep Sinha, Swinburne University; Email: msinha[at]swinburne.edu.au Abstract Software is now critical for modern research, and frequently, scientific breakthroughs are enabled by high-quality and innovative research software. Consequently, there is an increased demand for “Research Software Engineers (RSEs)” - people who are well-trained domain scientists with highly specialised …

Wednesday 21 Jul 2021 @ 12:00 p.m., David Caro building, Level 2, Hercus Theatre (+Zoom) Dr Anshu Gupta, Curtin Institute of Radio Astronomy; Email: anshu.gupta[at]curtin.edu.au Abstract I combine optical and near-infrared spectroscopy of galaxies with state-of-the-art cosmological simulations to study the galaxy formation and evolution. In this talk, I will present recent results where we find that massive galaxies grow via accretion of …

Wednesday 07 Jul 2021 @ 12:00 p.m., David Caro building, Level 2, Hercus Theatre (+Zoom) Dr Rory Smith, Monash University; Email: Rory.Smith[at]monash.edu Abstract In January 2020, the LIGO and Virgo observatories twice detected gravitational waves from the inspiral and merger of neutron stars with black holes. In this talk, I will describe the detection and characterization of this observation of a new source …
