Title:  Is Nature Its Own Mirror? Parity-Violation with Galaxy Quartets in BOSS

Abstract:  Recently we have shown that the galaxy 4-point correlation function, which measures an excess of quartets of galaxies over random, is sensitive to parity violation in our universe’s large-scale structure. It is fundamentally 3D and thus has a handedness even after averaging over orientations, in contrast to galaxy pair and triplet correlations. With this new observable, we have detected parity violation at high statistical significance using the largest currently available sample, the SDSS Baryon Oscillation Spectroscopic Survey’s roughly 1 M galaxies. If confirmed by upcoming sky surveys such as DESI this would indicate new physics operant in the Universe’s earliest moments. In this talk I will discuss this result and the many systematics tests performed to test its robustness, as well as prospects for the future, especially with DESI data.

Title: Probing exotic energy injection with the CMB and early star formation

Abstract: Dark matter interactions with Standard Model particles can inject energy at early times, altering the standard evolution of the early universe. In particular, this energy injection can perturb the spectrum of the cosmic microwave background (CMB) away from that of a perfect blackbody, alter the CMB anisotropy spectrum, and affect processes by which the first stars form. For this study, I will discuss recent work to upgrade the DarkHistory code package to more carefully track interactions among low energy electrons, hydrogen atoms, and radiation, in order to accurately compute the evolution of the CMB spectral distortion in the presence of Dark Matter energy injection. I will show results for the contribution to the spectral distortions from redshifts z < 3000 for arbitrary energy injection scenarios, new CMB anisotropy constraints on light dark matter, as well as the effect of exotic energy injection on early star formation.

Title:  Constraining cosmological models with the effective field theory of large-scale structures

Abstract:  In this talk, I will present the paradigm of the effective field theory of large-scale structures (EFTofLSS) and how it can be used to constrain cosmological models. First, I will discuss the consistency of this theory and its predictive power, and then I will present the constraints of the EFTofLSS applied to BOSS and eBOSS data on the LCDM model. Finally, I will mention the constraints from this theory on early dark energy, a model that potentially resolves the Hubble tension, and on decaying cold dark matter,  a model that possibly resolves the S8 tension.

Title:  Quantum Gravity and A Unification of the Dark Sector

Abstract:  In this talk I apply consistency conditions of quantum gravity to the dark sector.   Motivated by the smallness of the dark energy combined with other experimental data, one is naturally led to a corner of the quantum gravity landscape with one extra mesoscopic dimension in the micron range. Interestingly this also leads to graviton excitations in the 5th dimension as an unavoidable candidate for the dark matter.  Moreover TCC conjecture applied to the late time cosmology motivates specific initial conditions in this scenario, leading to the right abundance of dark matter gravitons and an explanation of the cosmological coincidence problem.  We show how this novel dark matter scenario may also resolve the S8 tension.

 The aggregate light emitted by all extragalactic sources can be measured either as an absolute intensity or through its spatial fluctuations; these are known as line-intensity mapping (LIM) when a particular line transition is targeted. I will discuss how these measurements can be used both to investigate the presence of speculative sources of radiation, such as decaying dark matter, and learn about galaxy evolution. I then focus on intensity mapping and discuss how the unique characteristics of these measurements (e.g. wide redshift coverage, sensitivity to faint sources, and mapping speed) may enable a variety of scientific goals, some of the challenges in realizing them and promising future directions.

• Sebastian Wagner-Carena (External Speaker from Stanford), "From Images to Dark Matter: End-to-End Inference of Substructure from Hundreds of Strong Gravitational Lenses", @ Zoom, at 5:00pm

Constraining the distribution of small-scale structure in our universe allows us to probe alternatives to the cold dark matter paradigm. Strong gravitational lensing offers a unique window into small dark matter halos because these halos impart a gravitational lensing signal even if they do not host luminous galaxies. We create large datasets of strong lensing images with realistic low-mass halos, Hubble Space Telescope (HST) observational effects, and galaxy light from HST's COSMOS field. Using a simulation-based inference pipeline, we train a neural posterior estimator of the subhalo mass function (SHMF) and place constraints on populations of lenses generated using a separate set of galaxy sources. We find that by combining our network with a hierarchical inference framework, we can both reliably infer the SHMF across a variety of configurations and scale efficiently to populations with hundreds of lenses. By conducting precise inference on large and complex simulated datasets, our method lays a foundation for extracting dark matter constraints from the next generation of wide-field optical imaging surveys.
