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 […]

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 […]
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 […]

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 […]

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 […]
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 […]
Kavli Affiliate: Robert M. Wald | First 5 Authors: Daine L. Danielson, Gautam Satishchandran, Robert M. Wald, , | Summary: We show that if a massive body is put in a quantum superposition of spatially separated states, the mere presence of a black hole in the vicinity of the body will eventually destroy the coherence […]
