High-Precision Redshifts for Type Ia Supernovae with the Nancy Grace Roman Space Telescope P127 Prism

Kavli Affiliate: Richard Kessler | First 5 Authors: Bhavin A. Joshi, Louis-Gregory Strolger, Russell E. Ryan, Jr., Alexei V. Filippenko, Rebekah Hounsell | Summary: We present results from simulating slitless spectroscopic observations with the Nancy Grace Roman Space Telescope’s (Roman) Wide-Field Instrument (WFI) P127 prism spanning 0.75 $mu m$ to 1.8 $mu m$. We quantify […]

Gravity as a gapless phase and biform symmetries

Kavli Affiliate: Austin Joyce | First 5 Authors: Kurt Hinterbichler, Diego M. Hofman, Austin Joyce, Grégoire Mathys, | Summary: We study effective field theories (EFTs) enjoying (maximal) biform symmetries. These are defined by the presence of a conserved (electric) current that has the symmetries of a Young tableau with two columns of equal length. When […]

The Astrophysical Distance Scale: V. A 2% Distance to the Local Group Spiral M33 via the JAGB Method, Tip of the Red Giant Branch, and Leavitt Law

Kavli Affiliate: Wendy L. Freedman | First 5 Authors: Abigail J. Lee, Laurie Rousseau-Nepton, Wendy L. Freedman, Barry F. Madore, Maria-Rosa L. Cioni | Summary: The J-region asymptotic giant branch (JAGB) method is a new standard candle that is based on the stable intrinsic J-band magnitude of color-selected carbon stars, and has a precision comparable […]

Avoiding a Cluster Catastrophe: Retention Efficiency and the Binary Black Hole Mass Spectrum

Kavli Affiliate: Daniel E. Holz | First 5 Authors: Michael Zevin, Daniel E. Holz, , , | Summary: The population of binary black hole mergers identified through gravitational waves has uncovered unexpected features in the intrinsic properties of black holes in the Universe. One particularly surprising and exciting result is the possible existence of black […]

Distances to Local Group Galaxies via Population II, Stellar Distance Indicators I: The Sculptor Dwarf Spheroidal

Kavli Affiliate: Wendy L. Freedman | First 5 Authors: Quang H. Tran, Taylor J. Hoyt, Wendy L. Freedman, Barry F. Madore, Elias K. Oakes | Summary: We determine the distance to the Sculptor Dwarf Spheroidal via three Population II stellar distance indicators: (a) the Tip of the Red Giant Branch (TRGB), (b) RR Lyrae variables […]

Constraining Feeble Neutrino Interactions with Ultralight Dark Matter

Kavli Affiliate: Gordan Krnjaic | First 5 Authors: Abhish Dev, Gordan Krnjaic, Pedro Machado, Harikrishnan Ramani, | Summary: If ultralight $(ll$ eV), bosonic dark matter couples to right handed neutrinos, active neutrino masses and mixing angles depend on the ambient dark matter density. When the neutrino Majorana mass, induced by the dark matter background, is […]

The Tianlai dish array low-z surveys forecasts

Kavli Affiliate: Albert Stebbins | First 5 Authors: Olivier Perdereau, Réza Ansari, Albert Stebbins, Peter T. Timbie, Xuelei Chen | Summary: We present the science case for surveys with the Tianlai dish array interferometer tuned to the $left[ 1300, 1400 right] mathrm{MHz}$ frequency range. Starting from a realistic generation of mock visibility data according to […]
