Kavli Affiliate: Clarence Chang | First 5 Authors: Kristin Dona, Jesse Liu, Noah Kurinsky, David Miller, Pete Barry | Summary: Dedicated spectrometers for terahertz radiation with [0.3, 30] THz frequencies using traditional optomechanical interferometry are substantially less common than their infrared and microwave counterparts. This paper presents the design and initial performance measurements of a […]

Kavli Affiliate: Marcela Carena | First 5 Authors: Sebastian Baum, Marcela Carena, Nausheen R. Shah, Carlos E. M. Wagner, | Summary: A new measurement of the muon anomalous magnetic moment has been reported by the Fermilab Muon g-2 collaboration and shows a $4.2sigma$ departure from the most precise and reliable calculation of this quantity in […]

Kavli Affiliate: Angela V. Olinto | First 5 Authors: Thomas C. Paul, Sarah T. Reese, Luis A. Anchordoqui, Angela V. Olinto, Thomas Y. Chen | Summary: Macroscopic dark matter (or macro) provides a broad class of alternative candidates to particle dark matter. These candidates would transfer energy primarily through elastic scattering, and this linear energy […]

Kavli Affiliate: Marcela Carena | First 5 Authors: Marcela Carena, Claudius Krause, Zhen Liu, Yikun Wang, | Summary: Electroweak symmetry non-restoration up to high temperatures well above the electroweak scale offers new alternatives for baryogenesis. We propose a new approach for electroweak symmetry non-restoration via an inert Higgs sector that couples to the Standard Model […]

Kavli Affiliate: Brian Nord | First 5 Authors: Priyamvada Natarajan, Kwok Sun Tang, Robert McGibbon, Sadegh Khochfar, Brian Nord | Summary: We present QuasarNet, a novel research platform for the data-driven investigation of super-massive black hole (SMBH) populations. While SMBH data sets — observations and simulations — have grown rapidly in complexity and abundance, our […]

Kavli Affiliate: Andrey V. Kravtsov | First 5 Authors: Vadim A. Semenov, Andrey V. Kravtsov, Nickolay Y. Gnedin, , | Summary: The spatial decorrelation of dense molecular gas and young stars observed on $lesssim 1$ kiloparsec scales in nearby galaxies indicates rapid dispersal of star-forming regions by stellar feedback. We explore the sensitivity of this […]

Kavli Affiliate: Michael Gladders | First 5 Authors: Brian Hayden, David Rubin, Kyle Boone, Greg Aldering, Jakob Nordin | Summary: The See Change survey was designed to make $z>1$ cosmological measurements by efficiently discovering high-redshift Type Ia supernovae (SNe Ia) and improving cluster mass measurements through weak lensing. This survey observed twelve galaxy clusters with […]

Kavli Affiliate: Michael Gladders | First 5 Authors: Peter R. Williams, Tommaso Treu, Håkon Dahle, Stefano Valenti, Louis Abramson | Summary: We present CIV BLR modeling results for the multiply imaged $z=2.805$ quasar SDSS J2222+2745. Using data covering a 5.3 year baseline after accounting for gravitational time delays, we find models that can reproduce the […]

Kavli Affiliate: Edward W. Kolb | First 5 Authors: Edward W. Kolb, Andrew J. Long, Evan McDonough, , | Summary: We extend the swampland from effective field theories (EFTs) inconsistent with quantum gravity to EFTs inconsistent with quantum supergravity. This enlarges the swampland to include EFTs that become inconsistent when the gravitino is quantized. We […]
