Freeform three-mirror anastigmatic large-aperture telescope and receiver optics for CMB-S4

Kavli Affiliate: John Carlstrom | First 5 Authors: Patricio A. Gallardo, Roberto Puddu, Kathleen Harrington, Bradford Benson, John Carlstrom | Summary: CMB-S4, the next-generation ground-based cosmic microwave background (CMB) observatory, will provide detailed maps of the CMB at millimeter wavelengths to dramatically advance our understanding of the origin and evolution of the universe. CMB-S4 will […]

Entanglement Suppression, Enhanced Symmetry and a Standard-Model-like Higgs Boson

Kavli Affiliate: Marcela Carena | First 5 Authors: Marcela Carena, Ian Low, Carlos E. M. Wagner, Ming-Lei Xiao, | Summary: We study information-theoretic properties of scalar models containing two Higgs doublets $Phi_a$, where $a=1,2$ is the flavor quantum number. Considering the 2-to-2 scattering $Phi_a Phi_b to Phi_c Phi_d$ as a two-qubit system in the flavor […]

AdS3 Orbifolds, BTZ Black Holes, and Holography

Kavli Affiliate: Emil J. Martinec | First 5 Authors: Emil J. Martinec, , , , | Summary: Conical defects of the form $(AdS_3times S^3)/Z_k$ have an exact orbifold description in worldsheet string theory, which we derive from their known presentation as gauged Wess-Zumino-Witten models. The configuration of strings and fivebranes sourcing this geometry is well-understood, […]

Metallicity Distribution Functions of 13 Ultra-Faint Dwarf Galaxy Candidates from Hubble Space Telescope Narrowband Imaging

Kavli Affiliate: Alexander P. Ji | First 5 Authors: Sal Wanying Fu, Daniel R. Weisz, Else Starkenburg, Nicolas Martin, Alessandro Savino | Summary: We present uniformly measured stellar metallicities for 463 stars in 13 Milky Way (MW) ultra-faint dwarf galaxies (UFDs; $M_V = -7.1$ to $-0.8$) using narrowband CaHK (F395N) imaging taken with the Hubble […]

Binning is Sinning: Redemption for Hubble Diagram using Photometrically Classified Type Ia Supernovae

Kavli Affiliate: Richard Kessler | First 5 Authors: Richard Kessler, Maria Vincenzi, Patrick Armstrong, , | Summary: Bayesian Estimation Applied to Multiple Species (BEAMS) is implemented in the BEAMS with Bias Corrections (BBC) framework to produce a redshift-binned Hubble diagram (HD) for Type Ia supernovae (SNe Ia). BBC corrects for selection effects and non-SNIa contamination, […]
