Kavli Affiliate: Emil J. Martinec | First 5 Authors: Andrea Dei, Emil J. Martinec, , , | Summary: We formulate a worldsheet description of string theory in the background of a single decoupled NS5-brane, which is a particularly simple example of “little string” holography. The worldsheet theory involves a gauged Wess-Zumino-Witten model for the group […]
Kavli Affiliate: John E. Bowers | First 5 Authors: Chen Shang, Weng W. Chow, Galan Moody, John E. Bowers, | Summary: A study was performed to determine the extent cavity enhancement may increase single-photon production while maintaining single-photon purity. It was found that certain combinations of cavity lifetime and light-matter coupling strength can lead to […]
Kavli Affiliate: Joshua A. Frieman | First 5 Authors: Anowar J. Shajib, Tommaso Treu, Sherry H. Suyu, David Law, Akın Yıldırım | Summary: Spatially resolved stellar kinematics has become a key ingredient in time-delay cosmography to break the mass-sheet degeneracy in the mass profile and, in turn, provide a precise constraint on the Hubble constant […]
Kavli Affiliate: Alexander P. Ji | First 5 Authors: Benjamin Cohen, Alexander P. Ji, Peter S. Ferguson, Sergey E. Koposov, Alex Drlica-Wagner | Summary: Stellar streams are sensitive laboratories for understanding the small-scale structure in our Galaxy’s gravitational field. Here, we analyze the morphology of the $300S$ stellar stream, which has an eccentric, retrograde orbit […]
Kavli Affiliate: David Charbonneau | First 5 Authors: Juliana García-Mejía, Zoë L. de Beurs, Patrick Tamburo, Andrew Vanderburg, David Charbonneau | Summary: We present a ground-based transit detection of HIP 41378 f, a long-period ($P = 542$ days), extremely low-density ($0.09 pm 0.02$ g cm$^{-3}$) giant exoplanet in a dynamically complex system. Using photometry from […]
Kavli Affiliate: Savdeep Sethi | First 5 Authors: Christian Ferko, Savdeep Sethi, , , | Summary: One of the key issues in holography is going beyond $mathrm{AdS}$ and defining quantum gravity in spacetimes with a null boundary. Recent examples of this type involve linear dilaton asymptotics and are related to the $T overline{T}$ deformation. We […]
Kavli Affiliate: Chao-Lin Kuo | First 5 Authors: E. Camphuis, W. Quan, L. Balkenhol, A. R. Khalife, F. Ge | Summary: We present measurements of the temperature and E-mode polarization angular power spectra of the cosmic microwave background (CMB) from observations of 4% of the sky with SPT-3G, the current camera on the South Pole […]
Kavli Affiliate: Alexander P. Ji | First 5 Authors: Vinicius M. Placco, Guilherme Limberg, Anirudh Chiti, Deepthi S. Prabhu, Alexander P. Ji | Summary: In this work, we present high-resolution spectroscopic observations for six metal-poor stars with [Fe/H]<-3 (including one with [Fe/H]<-4), selected using narrow-band Ca II HK photometry from the DECam MAGIC Survey. The […]
Kavli Affiliate: David Charbonneau | First 5 Authors: Emily K. Pass, Phillip A. Cargile, Victoria DiTomasso, Romy Rodríguez Martínez, David Charbonneau | Summary: As the field of exoplanetary astronomy has matured, there has been growing demand for precise stellar abundances to probe subtle correlations between stellar compositions and planetary demographics. However, drawing population-level conclusions from […]
Kavli Affiliate: Robert Edwards | Authors: Craig Liddicoat, Bart A Eijkelkamp, Timothy R Cavagnaro, Jake M Robinson, Kiri Joy Wallace, Andrew D Barnes, Garth Harmsworth, Damien J Keating, Robert A Edwards and Martin F Breed | Summary: The global rise in human allergic and autoimmune diseases is linked to altered environmental microbiome exposures from increasing […]
