Astronomy & Astrophysics Colloquium: Ed Bertschinger - Space for All of us: Inclusion and Belonging in 2024

Elite universities have never been more demographically diverse, produced more equitable outcomes, nor been more inclusive. Yet many faculty do not feel a sense of belonging and many students do not feel heard. This talk will show how to understand these differences using three kinds of data: demographics, climate survey data, and policies and practices. Individual stories and narratives prove to be crucial.

Spring 2024 EHS Orientation for Wright Lab Shops

Wright Lab will host two, identical 1-hour Environmental Health and Safety (EHS) Shop Orientations on Friday, January 26 at 11:30 a.m. and Tuesday, January 30 at 3:00 p.m. The EHS shop orientation is offered each semester and is required to be taken once by anyone who would like to gain access and make use of the research and teaching shops at Wright Lab.

NPA Seminar: Nicole Lewis, Rice University, "Search for baryon number carrier in photonuclear processes and heavy-ion collisions at STAR"

Baryon number is a strictly conserved quantum number. It is conventionally assumed to be divided equally among the three valence quarks inside each baryon, but this has never been verified experimentally. An alternative model is the baryon junction: a Y-shaped configuration of nonperturbative gluons that is connected to all three valence quarks and carries the baryon number. In this talk we will present two measurements from the STAR experiment which are sensitive the baryon number carrier.

NPA Seminar: Nickolas Kokron, Princeton, "Probing the S(igma)-8 tension at the onset of stage-IV cosmic surveys"

In 1970, Allan Sandage famously described Cosmology as “A search for two numbers”. In the half-century since that description of the field was penned, as Stage III cosmic surveys come to an end and Stage-IV surveys begin taking data, the field finds itself having measured the six parameters of the concordance ΛCDM model at nearly 1% precision. However, different experiments now report different values for two of these parameters – namely the Hubble Constant and the variance of dark matter density fluctuations, S(igma) 8 – at varying levels of significance.

NPA Seminar: Adriaan Duivenvoorden, Flatiron Institute; Simons Foundation, "Cosmology from the fine details of the microwave sky with the Atacama Cosmology Telescope and the Simons Observatory"

Modern ground-based microwave observatories offer a high-resolution perspective on the cosmic microwave background (CMB) and its secondary components, complementing galaxy surveys and the low resolution CMB data from the Planck and WMAP satellites. In this talk, I will introduce two such observatories, the Atacama Cosmology Telescope (ACT) and the Simons Observatory. The ACT collaboration is preparing to release its sixth public data release. This release, DR6, is the result from a 6-year-long survey covering 40% of the sky at arcminute resolution.
