Kavli Affiliate: Bradford A. Benson | First 5 Authors: Rohan Dahale, Ilje Cho, Kotaro Moriyama, Kaj Wiik, Paul Tiede | Summary: We investigate the origin of the elliptical ring structure observed in the images of the supermassive black hole M87*, aiming to disentangle contributions from gravitational, astrophysical, and imaging effects. Leveraging the enhanced capabilities of […]
Kavli Affiliate: Gordan Krnjaic | First 5 Authors: Gordan Krnjaic, , , , | Summary: In light of recent DAMIC-M results, we present the status of thermal-relic dark matter $chi$ coupled to a kinetically-mixed dark photon $A^prime$. In the predictive "direct annihilation" regime, $m_{A’} > m_chi$, the relic abundance depends on the kinetic mixing parameter, […]
Kavli Affiliate: Chihway Chang | First 5 Authors: Jazmine Jefferson, Yuuki Omori, Chihway Chang, Shrihan Agarwal, Joe Zuntz | Summary: In recent years, weak lensing shear catalogs have been released by various Stage-III weak lensing surveys including the Kilo-Degree Survey, the Dark Energy Survey, and the Hyper Suprime-Cam Subaru Strategic Program. These shear catalogs have […]
Kavli Affiliate: Marcela Carena | First 5 Authors: Marcela Carena, Guglielmo Coloretti, Wanqiang Liu, Mira Littmann, Ian Low | Summary: We consider 2-to-2 scatterings of Higgs bosons in a CP-conserving two-Higgs-doublet model (2HDM) and study the implication of maximizing the entanglement in the flavor space, where the two doublets $Phi_a$, $a=1,2$, can be viewed as […]

Kavli Affiliate: Wayne Hu | First 5 Authors: Tanisha Jhaveri, Tanvi Karwal, Wayne Hu, , | Summary: Under $Lambda$CDM, recent baryon acoustic oscillation (BAO) distance measures from DESI, which favor a low matter density $Omega_m$, are in moderate $2-3sigma$ tension with cosmic microwave background (CMB) observations. This tension appears alternately as a preference for the […]
Kavli Affiliate: Nickolay Y. Gnedin | First 5 Authors: Hanjue Zhu, Nickolay Y. Gnedin, , , | Summary: We investigate the properties of cosmological ionization fronts during the Epoch of Reionization using the CROC simulations. By analyzing reionization timing maps, we characterize ionization front velocities and curvatures and their dependence on the density structure of […]
Kavli Affiliate: Bradford A. Benson | First 5 Authors: Frank J. Qu, Fei Ge, W. L. Kimmy Wu, Irene Abril-Cabezas, Mathew S. Madhavacheril | Summary: We present the tightest cosmic microwave background (CMB) lensing constraints to date on the growth of structure by combining CMB lensing measurements from the Atacama Cosmology Telescope (ACT), the South […]

Kavli Affiliate: Marcela Carena | First 5 Authors: Marcela Carena, Aurora Ireland, Tong Ou, Isaac R. Wang, | Summary: A precise determination of the bubble wall velocity $v_w$ is crucial for making accurate predictions of the baryon asymmetry and gravitational wave (GW) signals in models of electroweak baryogenesis (EWBG). Working in the local thermal equilibrium […]
