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: Herman L. Marshall | First 5 Authors: Unnati Kashyap, Thomas J. Maccarone, Mason Ng, Eliot C. Pattie, Swati Ravi | Summary: We report the first X-ray polarimetric results of the neutron star (NS) low-mass X-ray binary (LMXB) Z-source GX 349+2 using the Imaging X-ray Polarimetry Explorer (IXPE). We discovered that the X-ray source […]

Kavli Affiliate: Shigeki Matsumoto | First 5 Authors: Sung Hak Lim, Kohei Hayashi, Shun’ichi Horigome, Shigeki Matsumoto, Mihoko M. Nojiri | Summary: The kinematics of stars in dwarf spheroidal galaxies have been studied to understand the structure of dark matter halos. However, the kinematic information of these stars is often limited to celestial positions and […]

Kavli Affiliate: Claudio Ricci | First 5 Authors: Marzena Śniegowska, Benny Trakhtenbrot, Lydia Makrygianni, Iair Arcavi, Claudio Ricci | Summary: AT 2019aalc is a peculiar sequence of highly variable emission events observed towards the nucleus of the broad-line AGN SDSS J152416.66+045119.0. The system exhibited two distinct UV/optical flares (the first detected in 2019, the second […]
Kavli Affiliate: Robert A. Simcoe | First 5 Authors: Dominika Ďurovčíková, Anna-Christina Eilers, Romain A. Meyer, Emanuele Paolo Farina, Eduardo Bañados | Summary: The existence of billion-solar-mass black holes hosted in luminous quasars within the first gigayear of cosmic history poses a challenge to our understanding of supermassive black hole (SMBH) growth. The problem is […]
Kavli Affiliate: Debanjan Chowdhury | First 5 Authors: Haoyu Guo, Debanjan Chowdhury, , , | Summary: Metals at the brink of electronic quantum phase transitions display high-temperature superconductivity, competing orders, and unconventional charge transport, revealing strong departures from conventional Fermi liquid behavior. Investigation of these fascinating intertwined phenomena has been at the center of research […]
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 […]
