Gene expression in all organisms is controlled by short DNA and RNA sequences called cis-regulatory elements (CREs). Proteins in the cellular milieu bind to nucleic acid sequences present within CREs, interact with one another, and thus form macromolecular complexes that modulate the expression of nearby genes. My lab uses…

We present new maps of the Galactic Center in total intensity and polarization made with the Atacama Cosmology Telescope (ACT). We combine dedicated, arcminute-resolution ACT observations over a 32 deg^2 field with Planck intensity and polarization data at similar frequencies to produce maps with fidelity on both small and large angular scales…
Speaker: Dr. Dara Norman, a Full Scientist and Deputy Director of the Community Science and Data Center at the NSF’s National Optical and Infrared Astronomical Research Laboratory (NOIRLab)
Dr. Norman will highlight examples of past culture change in the field, growing trends toward implementation of the values that…
Underground rare-event search is a substantial branch in particle physics, in which particle dark matter (DM) direct detection and neutrinoless double β decay (0νββ) are two major topics. The elusive nature of the signals puts stringent requirements on the detector contamination level. Some particular interactions also require specific…

Abstract: I will discuss the detailed process by which slow contraction smooths and flattens the universe using an improved numerical relativity code that accepts initial conditions with non-perturbative deviations from homogeneity and isotropy along two independent spatial directions. Contrary to common descriptions of the early universe, I…
The rod-shaped bacterium Escherichia coli proliferates by a process of elongation, followed by constriction at its centre to create new cell poles. Despite intense study, some apparently simple questions about the dynamics of growth and division in E. coli continue to be debated - these include whether the cell length increases exponentially or…

The next analysis of ACT data will use precision-cosmology-capable maps of the microwave sky based on data taken by the Advanced ACT detector arrays since 2017. The maps will cover the full Advanced ACT footprint (~44% f_sky, see Aiola et al. 2020 and Mallaby…
I will discuss recent theoretical work on exciton physics in two-dimensional materials. First, I will focus on the neutral particle-hole pair excitations of correlated “orbital Chern insulators” recently detected in twisted bilayer graphene, whose approximately flat conduction and valence bands have equal and opposite non-zero Chern number…
Gravitational waves from the coalescence of compact binaries provide a unique opportunity to test gravity in the strong field regime. In particular, the postmerger phase of the gravitational signal is a proxy for the nature of the remnant.
This is of particular interest in view of some quantum-gravity models which predict the…
Active materials such as bacteria, molecular motors and eukaryotic cells continuously transform chemical energy taken from their surroundings to mechanical work. Dense active matter shows mesoscale turbulence, the emergence of chaotic flow structures characterised by high vorticity and self-propelled topological defects. I shall describe the…

Abstract:
Sarah Marie Bruno, Princeton University
"The projected impact of commercial satellite constellations on ground-based astronomy"
The ongoing commercialization of satellite technology is leading to the ubiquity of privately owned and operated satellite spacecraft in low-Earth orbits. These satellites can be used for…
In this seminar I will discuss recent progress on the use of planar crystals with hundreds of ions as a platform for quantum simulation of spin and spin-boson models. The key idea is the use of a pair of lasers to couple two internal levels of the ions, that act as a spin½ degree of freedom, to the…
