Detectable Changes in Astronomy

Cody Hall, AB 107

Federica Bianco (New York University)

March 07, 2018
14:00 - 15:00

The way we do science in general, and astronomy in particular, is changing rapidly. I will talk about the future of astronomy on the verge of the LSST survey. As the LSST Science Collaborations Coordinator, I will discuss how the whole science community is preparing…

Common envelope physics and the transients

Cody Hall, AB 107

Natasha Ivanova (University of Alberta)

February 28, 2018
14:00 - 15:00

Common-envelope events capture the imagination and are visually impressive, energetically noteworthy, and dramatically fate-defining episodes in the lives of close binary systems. During a common envelope event, two stars temporarily orbit within a shared envelope, and the episode ends with an exciting outburst, leaving behind…

The Universe’s Most Extreme Star-Forming Galaxies in Early, Massive Galaxy Protoclusters

Cody Hall, AB 107

Scott Chapman (Dalhousie University)

February 14, 2018
14:00 - 15:00

The star-forming, sub-millimeter galaxy (SMG) population represent the most intense stellar nurseries in the Universe. Their high star formation rates of 200-2000 Msun/yr (compared to the Milky Way’s 1 Msun/yr) pose a unique challenge for cosmological simulations of how galaxies form and evolve, particularly in…

Connecting Protoplanetary Disk and Exoplanet Atmospheric Composition

Cody Hall, AB 107

Edwin Bergin (University of Michigan)

February 07, 2018
14:00 - 15:00

In planetary atmospheres equilibrium chemistry will redistribute elements into specific carriers depending on local conditions.  Therefore to draw a link between planet formation and end-state composition, we need to measure absolute abundances and trace the bulk carriers of key elements, particularly carbon and oxygen.  In…

Outer Halos of Galaxies from Field to Cluster Environment

Cody Hall, AB 107

Rhea-Silvia Remus, Universitaets Sternwarte Muenchen (USM)

January 31, 2018
14:00 - 15:00

The outer halos of galaxies are a fantastic laboratory to study several important physical processes that shape the appearance of galaxies in the universe. While dominated by the dark matter component, the outer halos also harbor small galaxies orbiting around the main galaxy, and often…

Exoplanet Detectives: Seeking Clues to Explain the Diverse Architectures of Exoplanetary Systems

Cody Hall, AB 107

Heather Knutson (Caltech)

January 24, 2018
14:00 - 15:00

Over the past two decades ongoing surveys have detected thousands of new planetary systems around nearby stars. These systems include apparently single gas giant planets on short period orbits, closely packed systems of up to 5-6 “mini-Neptunes”, and solar-system-like architectures with either one small planet…

Data Visualization in the Planetarium

Cody Hall, AB 107

Mark Subbarao (Adler Planetarium)

January 17, 2018
14:00 - 15:00

The modern, digital, networked planetarium is a powerful collaborative visualization environment. These facilities have the potential to both elevate the level of public science communication and serve as a data exploration tool for researchers. The International Planetarium Society’s Data to Dome initiative is working prepare…

Get Ready for the James Webb Space Telescope

Cody Hall, AB 107

René Doyon (Université de Montréal)

January 10, 2018
14:00 - 15:00

The James Webb Space Telescope (JWST) is currently in its final phase of integration and scheduled for launch in the spring of 2019, with science operations to commence six months later.  Equipped with four powerful science instruments, JWST will provide imaging and spectroscopy from 0.6…

X-ray-Driven Multiwavelength and Multimessenger Discovery

Cody Hall, AB 107

Daryl Haggard (McGill University)

December 06, 2017
14:00 - 15:00

I will discuss the importance of time-resolved X-ray observations in studies of strong gravity near black holes and neutron stars, and also in the context of multiwavelength and multimessenger astrophysics. I’ll draw on two exciting examples: Sgr A* and GW170817. X-ray and multiwavelength monitoring of…
