The NASA Parker Solar Probe mission at the edge of the solar streamer belt
Stuart Bale
11:00am|Virtual Meeting
The physics of astrophysical coronal heating and the origin of the slow solar wind remain compelling problems in heliospheric physics, and plasma astrophysics more generally. The NASA Parker Solar Probe mission was launched in late 2018 and...

Galaxy Clusters : the largest particle accelerators in the Universe
Gianfranco Brunetti
11:00am|Virtual Meeting

Galaxy clusters and cosmic filaments are the largest structures in the Universe. During mergers between clusters shocks and turbulence are driven in the intra-cluster-medium (ICM) and dissipate a fraction of their energy into particle acceleration...

New Probes of Black Hole Variability
Daryl Haggard
11:00am|Virtual Meeting

It’s been a fantastic decade for black hole studies, highlighted by the 2017 and 2020 Nobel Prizes in Physics. Multiple Galactic Center research groups, the Event Horizon Telescope, and LIGO/Virgo continue to bring rapid-fire new observations to...

2020 Update on JWST: Time Domain, Cluster Lensing and Caustic Transit Searches for First Light Objects
Rogier Windhorst
11:00am|Virtual Meeting

In this talk, I will give the 2020 summary of the 6.5 meter James Webb Space Telescope (JWST), the near--mid-IR sequel to both Hubble and Spitzer. All hardware has been built, and is in the final stages of testing for its launch scheduled in October...

Galactic Archaeology with Gaia and Large Spectroscopic Surveys
Keith Hawkins
11:00am|Virtual Meeting

One of the key objectives of modern astrophysics is to understand the formation and evolution galaxies. In this regard, the Milky Way is a critical testing ground for our theories of galaxy formation. However, dissecting the assembly history of the...

Origins of Structure in Inner Planetary Systems
Ruth Murray-Clay
11:00am|Virtual Meeting

Why do many stars host close-in chains of super-Earths? Why are eccentric gas giants found in some inner planetary systems? What determines which of these outcomes will occur around a particular star? I will present a possible framework for...
