Princeton University Seminar in Survey Science

DESI-1 and DESI-2: informal update on the current status
Martin White
11:00am|Zoom and Peyton Dome Room

I will discuss the current status of DESI-1, some forecasts for the next set of cosmological constraints from DESI and highlight the southern expansion of the footprint happening between now and December 2028. Then I will present the current plans...

Princeton University Gravity Initiative Seminar

On the uniqueness of Kerr-de Sitter
Allen Fang
12:30pm|Jadwin Hall, Princeton Gravity Initiative, 4th Floor

Abstract: The uniqueness of the Kerr-de Sitter family of  black hole spacetimes as stationary solutions to the Einstein vacuum equations is a crucial ingredient to understanding the final states of positive cosmological constant universes, such as...

Institute for Advanced Study / Princeton University Joint Astrophysics Colloquium

Searching for supermassive black hole binaries
Maria Charisi
11:00am|Peyton Hall Auditorium

Supermassive black hole binaries (SMBHBs) should be common in galactic nuclei as a result of frequent galaxy mergers. Yet they remain undetectable, especially during the final stage of their evolution. At this stage, SMBHBs are expected to emit...

Rutgers University Astrophysics Seminar

Dust microphysics and its role in feedback
Nadine Soliman
11:00am|Serin Hall Rm 330W, Rutgers and Zoom

Dust plays a central role in regulating astrophysical environments across a wide range of scales. In active galactic nuclei (AGN), radiation pressure on dust launches large-scale winds that couple energy from the black hole to the surrounding galaxy...

Princeton University Cosmology Group Meeting

Modeling large-scale structure in a multi-survey world (new samples and new techniques)
Martin White
4:15pm|Peyton Hall, Auditorium, or Zoom

Abstract: We are now well into the era of “multiple” large cosmology surveys. Moving forward we anticipate that much of the best science will come from combining observations across surveys, so we need to learn how to do this well! I will describe...

University of Pennsylvania Astrophysics Seminar

The SPHEREx all-sky NIR spectroscopic survey
Phil Korngut
3:30pm|U.Penn, David Rittenhouse Laboratory, 4E19

The SPHEREx near-infrared space telescope is an all-sky spectroscopic survey mission launched on March 12th, 2025. In addition to providing the community with a spectral database applicable to a wide range of investigations, it is optimized to...
