Anderson self-duality of topological modular forms, its differential-geometric manifestations, and vertex operator algebras

Kavli Affiliate: Yuji Tachikawa | First 5 Authors: Yuji Tachikawa, Mayuko Yamashita, , , | Summary: Inspired by consideration in heterotic string theory, we construct a morphism of spectra from $mathrm{KO}((q))/mathrm{TMF}$ to $Sigma^{-20}I_{mathbb{Z}} mathrm{TMF}$, which we show to be an isomorphism and to implement the Anderson self-duality of $mathrm{TMF}$. We will use this to factor […]

This morphism is then used to define another morphism from $mathrm{TMF}$ to $Sigma^{-20}I_{mathbb{Z}}(mathrm{MSpin}/mathrm{MString})$, […]

Quantifying Uncertainties on the Tip of the Red Giant Branch Method

Kavli Affiliate: Wendy L. Freedman | First 5 Authors: Barry F. Madore, Wendy L. Freedman Kayla A. Owens, In Sung Jang, , | Summary: We present an extensive grid of numerical simulations quantifying the uncertainties in measurements of the Tip of the Red Giant Branch (TRGB). These simulations incorporate a luminosity function composed of 2 […]

The impact of UV variability on the abundance of bright galaxies at $z geq 9$

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Xuejian Shen, Mark Vogelsberger, Michael Boylan-Kolchin, Sandro Tacchella, Rahul Kannan | Summary: JWST observations have revealed a population of galaxies bright enough that potentially challenge standard galaxy formation models in the $Lambda$CDM cosmology. Using a minimal empirical framework, we investigate the influence of variability on the rest-frame […]

Measurement of ultra-high-energy diffuse gamma-ray emission of the Galactic plane from 10 TeV to 1 PeV with LHAASO-KM2A

Kavli Affiliate: Li Xin Li | First 5 Authors: Zhen Cao, F. Aharonian, Q. An, Axikegu, Y. X. Bai | Summary: The diffuse Galactic $gamma$-ray emission, mainly produced via interactions between cosmic rays and the diffuse interstellar medium, is a very important probe of the distribution, propagation, and interaction of cosmic rays in the Milky […]

Metal-poor stars observed with the Magellan Telescope. IV. Neutron-capture element signatures in 27 main-sequence stars

Kavli Affiliate: Anna Frebel | First 5 Authors: Mohammad K. Mardini, Anna Frebel, Leyatt Betre, Heather Jacobson, John E. Norris | Summary: Based on high-resolution spectra obtained with Magellan/MIKE, we present a chemo-dynamical analysis for 27 near main-sequence turnoff metal-poor stars, including 20 stars analyzed for the first time. The sample spans a range in […]
