NPA Zoom Seminar, Ruby Byrne, University of Washington, "Measuring the Epoch of Reionization: Progress, Challenges, and Next Steps for High Redshift 21 cm Cosmology"

The 21 cm emission line from neutral hydrogen represents a promising observational probe of cosmological evolution. In particular, measuring the highly redshifted 21 cm emission from the Epoch of Reionization (EoR) will illuminate a crucial and currently poorly understood period in cosmological history. The EoR denotes the period when radiation from early galaxies and black holes ionized the intergalactic medium.

NPA Zoom Seminar, Ho San Ko, LBL, "Accessing Generalized Parton Distributions at Jefferson Lab"

An exciting scientific frontier is the 3-dimensional exploration of nucleon (and nuclear) structure: nuclear femtography. The study of Generalized Parton Distributions (GPDs) captures the images of the transverse position distributions of fast moving quarks. Therefore, they provide richer information about the nucleon structure than the well known form factors and parton distribution functions. GPDs are accessible via exclusive reactions, where all particles in the final state are identified.

Wright Lab All Hands Meeting

We invite all members of our community to gather together weekly on Mondays via Zoom to check in with each other and hear what is going on around our community. Today’s program includes updates on recent projects from the APC (Arina Telles) and an update on the planning for the new Physical Sciences Building (PSEB) (Karsten Heeger).

NPA Zoom Seminar, Stefania Amodeo, Cornell University, "Halo gas thermodynamics from the CMB: results from the Atacama Cosmology Telescope DR5"

The thermodynamic properties of the ionized baryons in galaxies, groups, and clusters encode the effects of the assembly history and feedback processes that shape galaxy and cluster formation. These properties can be studied through the imprints that the scattering of cosmic microwave background (CMB) photons off the free-electron gas in galaxies and clusters leave on high resolution CMB maps: the thermal and kinematic Sunyaev-Zel’dovich effects.

Wright Lab All Hands Meeting, Karsten Heeger, "Planning for DEI action"

Members of the Wright Lab community are invited to join to discuss and provide input to the department’s DEI action plan at the all-hands meeting time of 9:30 on Monday, October 12. The action plan has been developed by the Physics DEIAP writing group and the department’s APS-IDEA team, together with the CDC and the department community.
