BTZ Black Holes From the Worldsheet
August 28, 2023 2:00 pm – 3:00 pm (CDT) MIST M102
BTZ Black Holes From the Worldsheet

Speaker: Emil Martinec (University of Chicago)

We discuss two aspects of worldsheet string dynamics in the presence of AdS3 (BTZ) black holes.  First, we construct AdS3 orbifolds describing conical defect geometries that prepare pure state black holes through Euclidean evolution, and examine aspects of the bulk/boundary correspondence.  Second, BTZ black holes can discharge by radiating wound [...]
JADES: Our First Year Capturing Light from the Dawn of Time
August 28, 2023 11:30 am – 12:30 pm (CDT) MIST M102
JADES: Our First Year Capturing Light from the Dawn of Time

Speaker: Kevin Hainline (University of Arizona)Host: Justin Spilker

Following the successful launch in December of 2021 of the James Webb Space Telescope (JWST), the global astronomical community has celebrated the exciting early results from the observatory. In this talk, Kevin Hainline, a member of the science team for the primary camera on board JWST, NIRCam, will discuss how [...]
Emergent Space and Time in Holographic Duality
September 11, 2023 2:00 pm – 3:00 pm (CDT) MIST M102
Emergent Space and Time in Holographic Duality

Speaker: Samuel Leutheusser (Princeton University)

In holographic duality, a higher dimensional quantum gravity system emerges from a lower dimensional conformal field theory (CFT) with a large number of degrees of freedom.  We propose a formulation of duality for a general causally complete bulk spacetime region, called subalgebra-subregion duality, which provides a framework to describe how [...]
Quasi-periodic Oscillations  in Supermassive Black Holes
September 11, 2023 11:30 am – 12:30 pm (CDT) MIST M102
Quasi-periodic Oscillations in Supermassive Black Holes

Speaker: Ashutosh Tripathi (Texas A&M University)Host: Grace Olivier

Quasi-periodic Oscillations (QPOs) have been observed in supermassive black holes across the whole electromagnetic spectrum. The claimed timescales range from a few tens of minutes to days, to weeks, and even a decade. Different models have been proposed to explain these QPOs which are primarily based on the timescales of periodicity. [...]
Status of the BeEST Heavy Neutrino Search Experiment
September 14, 2023 2:00 pm – 3:00 pm (CDT) MIST M102
Status of the BeEST Heavy Neutrino Search Experiment

Speaker: Inwook Kim (Lawrence Livermore National Laboratory)Host: Doojin Kim

The Beryllium Electron-capture in Superconducting Tunnel junctions (BeEST) experiment aims to detect the signatures of heavy neutrino mass eigenstates by meticulously measuring the recoil energy of the Li-7 daughter nucleus resulting from Be-7 electron capture. Operating a single uperconducting tunnel junction (STJ) detector, the BeEST has set world-leading limits on [...]
Symmetry, Soft Dynamics and Holography in Asymptotically Flat Spacetimes
September 18, 2023 2:00 pm – 3:00 pm (CDT) MIST M102
Symmetry, Soft Dynamics and Holography in Asymptotically Flat Spacetimes

Speaker: Daniel Kapec (Harvard University)

Despite our detailed understanding of holography in Anti-de Sitter space, flat space holography remains somewhat mysterious. “Celestial CFT” is one approach to the subject which attempts to recast quantum gravity in (d+2)-dimensional asymptotically flat spacetimes in terms of a d-dimensional Euclidean CFT residing at the conformal boundary. I will discuss [...]
Laser-interferometric and optomechanical technologies for astrophysics and Earth science
September 18, 2023 11:30 am – 12:30 pm (CDT) MIST M102
Laser-interferometric and optomechanical technologies for astrophysics and Earth science

Speaker: Felipe Guzman (Texas A&M University)Host: Justin Spilker

Coherent light enables length measurements of exquisite sensitivity that lie at the core of fascinating technological advances and engineering applications, as well as observations in fundamental physics, astrophysics, geodesy, and measurement science in general. Novel technologies and measurement principles find application in areas that are paradigm-changing; not only in fundamental [...]
Gravitational Waves from Nnaturalness
September 21, 2023 2:00 pm – 3:00 pm (CDT) MIST M102
Gravitational Waves from Nnaturalness

Speaker: Mudit Rai (Texas A&M University)Host: Doojin Kim

In this work, we investigate the gravitational wave aspect of the Nnaturalness models. They have been previously well studied in the context of higgs hierarchy problem. We find that Nnaturalness by itself cannot explain the recent observation of stochastic GW background observed recently by NANOGrav. However a large chunk of [...]
Generalized Symmetries in String Theory
September 25, 2023 2:00 pm – 3:00 pm (CDT) MIST M102
Generalized Symmetries in String Theory

Speaker: Max Hübner (University of Pennsylvania)

Generalized global symmetries occur in large classes of quantum field theories (QFTs). Whenever a QFT admits a string construction one can ask how structures associated with these symmetries lift and are characterized in the stringy realization of the QFT. For example topological operators realizing these symmetries in many cases admit [...]
Into the Dusty Universe with ALMA and JWST
September 25, 2023 11:30 am – 12:30 pm (CDT) MIST M102
Into the Dusty Universe with ALMA and JWST

Speaker: Jed McKinney (University of Texas, Austin)Host: Justin Spilker

Most of star-formation over the last 11 Billion years has happened within thick veils of dust, and in turn, dust shapes star-formation inside galaxies. Dust also absorbs and scatters light which can make optical probes of gas conditions difficult to measure, and hides very distant galaxies from even the most [...]
Compositeness from eV to TeV
September 28, 2023 2:00 pm – 3:00 pm (CDT) MIST M102
Compositeness from eV to TeV

Speaker: Benoît Assi (Fermilab)Host: Doojin Kim

Composite states occur over vast scales and play an important role in various domains of particle physics. In the first part I report on the recent development and application of non-relativistic QCD for the study of hadrons and multi-hadron systems in QCD and beyond. In particular, I will demonstrate how we [...]

Transforming Our Understanding of Galaxy Formation with the Power of JWST and ALMA

Transforming Our Understanding of Galaxy Formation with the Power of JWST and ALMA

Speaker: Wren Suess (University of California, Santa Cruz)Host: Justin Spilker

Galaxies are one of the fundamental building blocks of our universe, yet despite a century of study we still don’t understand how these vast cosmic ecosystems formed. The key challenge is that we want to measure physical properties like stellar mass, but all we observe is light. Making the translation [...]
