Kavli Affiliate: Andrey Kravtsov | First 5 Authors: Xihan Ji, Vasily Belokurov, Roberto Maiolino, Stephanie Monty, Yuki Isobe | Summary: Recent JWST observations have revealed a growing population of galaxies at $z>4$ with elevated nitrogen-to-oxygen ratios. These "N/O-enhanced" galaxies (NOEGs) exhibit near- to super-solar N/O at sub-solar O/H, clearly deviating from the well-established scaling relation […]

Kavli Affiliate: John E. Carlstrom | 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 […]
