CRA special seminar: Jason Gallicchio and Brian Shuve (Harvey Mudd College)

Bogg 1-44 VizLab

Jason Gallicchio and Brian Shuve from Harvey Mudd College Title: Improving Tests of Quantum Entanglement by using Light from Distant Quasars Abstract: Quantum entanglement, described by Einstein as "spooky action at a distance," is both fascinating philosophically and is the basis for quantum computing and quantum encryption. For this reason, it deserves to be tested … Continue reading "CRA special seminar: Jason Gallicchio and Brian Shuve (Harvey Mudd College)"

CRA Seminar: Dr. J. Brian Pitts (University of Cambridge)

Title: Change and Observables in Hamiltonian General Relativity   Abstract: Canonical (Hamiltonian) General Relativity and the associated project in quantum gravity are said to suffer from a problem of missing change, especially in "observables": part of the "problem of time." This talk addresses this problem by reflecting on definitions of observables. Typically observables in Hamiltonian … Continue reading "CRA Seminar: Dr. J. Brian Pitts (University of Cambridge)"

CRA seminar (Hari Sundar)

Bogg 1-44 VizLab

## Scalable Space-time adaptivity for Simulations of Binary Black Hole Intermediate-Mass-Ratio-Inspirals We present a highly scalable framework that targets problems of interest to the numerical relativity and broader astrophysics communities. This framework combines a parallel octree-refined adaptive mesh with a wavelet adaptive multiresolution and a physics module to solve the Einstein equations of general relativity. … Continue reading "CRA seminar (Hari Sundar)"

CRA seminar (Prof. Rahul Prasad Nigam)

Title: Wind noise mitigation in LIGO India structure. Abstract: We will discuss the observations that necessitate a detail study of wind noise effects on the LIGO-India structure and different ways we plan to mitigate such a noise.

Title/Abstract: 1. 10,000 solar mass black hole in NGC 4395 - primordial or no AGN feedback? I will present the reverberation-mapping study of the lowest-luminosity Seyfert 1 galaxy NGC 4395, based on the monitoring campaign in 2017 and 2018. The time delay of the Hα emission is measured as 83±14 min.. Combining with the Hα … Continue reading "CRA seminar (Prof. Jong-Hak Woo)"

CRA Cosmic Coffee: Brian Cook (Leiden University)

Howey N201/202 837 State Street, Atlanta, GA, United States

Title: Circumgalactic Media of Low-mass, Star-forming EAGLE Galaxies Abstract: Advances in observational techniques have made it possible to analyze the circumgalactic medium (CGM) in previously inaccessible detail. Often defined as the elusive region outside of the disk but within the virial radius of galaxies, the CGM is thought to have a critical role in processes … Continue reading "CRA Cosmic Coffee: Brian Cook (Leiden University)"

CRA Cosmic Coffee: Billy Quarles

Howey N201/202 837 State Street, Atlanta, GA, United States

Title: Obliquity Evolution of Earthlike planets in α Centauri AB Abstract: Changes in planetary obliquity, or axial tilt, influence the climatic conditions on a potentially habitable planet, where orbital perturbations from a binary star companion can drive these changes to extremes. We study the evolution of planetary obliquity for an Earthlike planet in the habitable … Continue reading "CRA Cosmic Coffee: Billy Quarles"
