NPA Seminar: Renee Ludlam, Wayne State University, "Characterizing the Properties of Accreting Neutron Stars through X-ray Observations"

The matter inside of a neutron star (NS) exists in an ultra-dense, cold state that we are unable to reproduce in Earth-based laboratories. Hence the only way to understand how matter behaves in this environment, i.e. determining the Equation of State (EoS), is through observations of these objects. NSs in low-mass X-ray binaries, where matter is stripped from a stellar companion to form an accretion disk, provide a unique opportunity to learn more about accretion physics and properties of the compact object itself.

NPA Seminar: Kyle Leach, Colorado School of Mines, "A Tale of Two Symmetries: Examining the PMNS and CKM Matrices via Weak Nuclear Decay"

It was the best of times, it was the worst of times. Just as the classic English novel lends its title well to the spirit of understanding symmetries in the standard model (SM), the opening words also concisely sum up the status of beyond standard model (BSM) physics searches through tests of the fundamental symmetric matrices over the past few decades. Despite the identical mathematical formalism that generates these matrices in the SM, empirically the level of observed mixing within these two are dramatically different.

NPA Seminar: Yeonju Go, BNL, "Jets and medium response in relativistic heavy ion collisions: Probing quark-gluon plasma"

Quark-gluon plasma (QGP), a unique phase of matter governed by Quantum Chromodynamics (QCD), is believed to have existed shortly (a few microseconds) after the Big Bang. Jets, collimated particle sprays originating from the fragmentation of hard-scattered quarks or gluons, serve as valuable probes for studying QGP produced in relativistic heavy ion collisions. As jets experience modifications due to the surrounding medium, so-called jet quenching, concurrently, jets influence the medium.

Introduction to HPC

This workshop is designed to introduce new users to the HPC resources available at Yale and to provide a comprehensive overview of the basic concepts needed to perform computing on the clusters:
accessing the clusters,
navigating a linux interface via bash commands, running interactive and batch jobs,
managing files,
troubleshooting workflows, and more.

ACCESS: Free HPC Resources Available to Researchers

The session will provide an overview of free ACCESS resources, outline the application process for various resource allocations, as well as reporting requirements for successful applications.

If you are a graduate student, post-doc or professor experiencing restrictions via CPU hour limits, gpu access, and/or other resource-related limitations then ACCESS may be the solution for you.

Parallel Programming with Python

This workshop introduces parallel programming concepts and demonstrates their implementation with Python. We will discuss parallel concepts, classes of parallel programs, Python’s implementation of parallel workflows, and showcase several toolkits for CPU and GPU-based parallel programming in Python. Additionally, we will discuss leveraging cluster-infrastructure for large parallel work via Slurm Job Arrays.

WIDG Seminar: Sophia Hollick, Yale, "COSINE-100 and ANAIS-112 Search for WIMPs"

This prospectus carries the goal of testing the DAMA/LIBRA (DL) dark matter claim by combining two collaborations who have set forth to reproduce the DL annual modulation signature, COSINE-100 and ANAIS-112. COSINE-100’s recent modulation results support both the no modulation case and the DL modulation case. ANAIS- 112 excludes DL to 2σ. A combination of the two experiments would allow for a sensitive search from opposite sides of the world, notably, Spain and Korea.
