NPA Zoom Seminar, Govert Nijs, MIT, "A Transverse Momentum Differential Global Analysis of Heavy Ion Collisions"

The understanding of heavy ion collisions and its quark-gluon plasma formation requires a complicated interplay of rich physics in a wealth of experimental data. In this work we compare for identified particles as a function of transverse momentum both the spectra and the anisotropic flow coefficients for both PbPb and pPb collisions. We do this in a model including a free streaming prehydrodynamic phase with variable velocity v_fs, thereby widening the scope of initial conditions. During the hydrodynamic phase we vary three new second order transport coefficients.

Yale Day of Data - Day 2

The 2020 Yale Day of Data will be held virtually over two half-days, December 3 and 4*, with the theme “In the Service of Data.”

The Yale Day of Data is an event that brings researchers together from a variety of disciplines to discuss finding, analyzing, and managing data.

NPA Zoom Seminar, Zhilei Xu, MIT, "Precision Cosmology: from the CMB to 21-cm Observations"

Over the past decades, the discovery and characterization of the cosmic microwave background (CMB) have marked the beginning of precision cosmology. At lower redshifts, future 21-cm signals from neutral hydrogen atoms also have great potential for cosmological and astrophysical studies. Observing 21-cm signals at different frequency bands produces a tomographic view of the universe. These observations will transform our current understanding of cosmology, commencing the 21-cm precision cosmology.

NPA Zoom Seminar, Jean-Francois Paquet, Duke, "Constraining the Viscosities of QCD with Relativistic Heavy Ion Collisions"

Fluids can be characterized by macroscopic properties such as viscosities or an equation of state. While the macroscopic properties of everyday fluids are determined by the electromagnetic interaction, an ensemble of fluids encountered in astrophysics and nuclear physics is dominated by the strong nuclear interaction. Relativistic collisions of heavy nuclei, performed at the Large Hadron Collider and the Relativistic Heavy Ion Collider, concentrate sufficient energy at the point of impact to produce a strongly-coupled plasma of deconfined nuclear matter.

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.
