Princeton University Galread [Galactic/Extragalactic Reading Group]

TBA
Discussion Leader: Nicolas Garavito
11:00am|Remote via Zoom

Each week, we hold a relatively informal seminar/discussion series with an emphasis on extra-galactic and large-scale structure astrophysics.

During Galread a leader/visitor presents a recent paper to the discussion group. The PDF of the paper is...

Institute for Advanced Study/Princeton University Early Universe/Cosmology Lunch Discussion

Topic 1: Galaxy Power Spectrum in General Relativity Topic 2: Towards the ultimate cosmological estimator
Nastassia Grimm and Francisco Villaescusa-Navarro
12:30pm|Until further notice, meetings will be held remotely on Zoom.

Topic 1: In this talk, I present the impact of general relativistic effects on the galaxy power spectrum. After introducing the full general relativistic expression for the galaxy number density, I define the theory power spectrum and describe its...

Institute for Advanced Study / Princeton University Joint Astrophysics Colloquium

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...

University of Pennsylvania Astronomy Seminar

Assembly bias of cosmic neutral hydrogen with neural networks and symbolic regression
Jay Wadekar
2:00pm|Virtual Event

Hydrodynamic simulations have a huge computational cost (~10 million CPU hours for 0.001 Gpc^3 volume), and cannot therefore be directly used in predictions for upcoming cosmological surveys which will probe 10-100 Gpc^3 volumes. Focusing on neutral...

Institute for Advanced Study Astrophysics Seminar

Characterizing the Architectures of Planetary Populations with Kepler and Next-Generation Doppler Surveys
11:00am|Virtual Meeting

NASA's Kepler mission conducted a large survey of planetary systems.  Recently, we have advanced from measuring occurrence rates as a function of planet size and period to characterizing the intrinsic distribution of planetary system architectures. ...

The Core-Collapse Supernova Critical Condition and the Birth of Millisecond Proto-Magnetar Winds
Matthias Raives
12:30pm|Virtual Meeting

The mechanism powering core-collapse supernovae remains uncertain. I will discuss aspects of the critical condition for explosion, focusing on the model problem of spherical accretion onto a standing accretion shock. My recent work explores the...
