A XRISM Observation of the Archetypal Radio-Mode Feedback System Hydra-A: Measurements of Atmospheric Motion and Constraints on Turbulent Dissipation

Posted by klaurent May 2, 2025MIT

Kavli Affiliate: Michael McDonald | Summary:We present XRISM Resolve observations centered on Hydra-A, a redshift z = 0.054 brightest cluster galaxy which hosts one of the largest and most powerful FR-I radio sources in the nearby Universe. We examine the effects of its high jet power on the velocity structure of the cluster’s hot atmosphere. […]

Entanglement Maximization and Mirror Symmetry in Two-Higgs-Doublet Models

Posted by klaurent May 1, 2025Chicago

Kavli Affiliate: Marcela Carena | 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 $Φ_a$, $a=1,2$, can be viewed as a qubit: $Φ_1=|0rangle$ and $Φ_2=|1rangle$. More specifically, we compute the scattering amplitudes for $Φ_a Φ_b […]

X-ray polarization study of the neutron star low-mass X-ray binary GX 349+2

Posted by dbos May 1, 2025MIT

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 […]

JFlow: Model-Independent Spherical Jeans Analysis using Equivariant Continuous Normalizing Flows

Posted by klaurent May 1, 2025Tokyo

Kavli Affiliate: Shigeki Matsumoto | 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 line-of-sight velocities, making full phase space analysis challenging. Conventional methods rely on projected analytic phase space density […]
