Comparison of Polarized Radiative Transfer Codes used by the EHT Collaboration

Kavli Affiliate: Bradford A. Benson | First 5 Authors: Ben S. Prather, Jason Dexter, Monika Moscibrodzka, Hung-Yi Pu, Thomas Bronzwaer | Summary: Interpretation of resolved polarized images of black holes by the Event Horizon Telescope (EHT) requires predictions of the polarized emission observable by an Earth-based instrument for a particular model of the black hole […]

Broadband X-ray timing and spectral characteristics of the accretion-powered millisecond X-ray pulsar MAXI J1816$-$195

Kavli Affiliate: Renxin Xu | First 5 Authors: Zhaosheng Li, Lucien Kuiper, Mingyu Ge, Maurizio Falanga, Juri Poutanen | Summary: We studied the broadband X-ray timing and spectral behaviors of the newly confirmed accreting millisecond X-ray pulsar MAXI J1816$-$195 during its 2022 outburst. We used the data from Insight-HXMT ME/HE, NICER and NuSTAR which cover […]

Absorption of Vector Dark Matter Beyond Kinetic Mixing

Kavli Affiliate: Gordan Krnjaic | First 5 Authors: Gordan Krnjaic, Tanner Trickle, , , | Summary: Massive vector particles are minimal dark matter candidates that motivate a wide range of laboratory searches, primarily exploiting a postulated kinetic mixing with the photon. However, depending on the high energy field content, the dominant vector dark matter (VDM) […]

High-density reflection spectroscopy of black hole X-ray binaries in the hard state

Kavli Affiliate: Erin Kara | First 5 Authors: Honghui Liu, Jiachen Jiang, Zuobin Zhang, Cosimo Bambi, Andrew C. Fabian | Summary: We present a high-density relativistic reflection analysis of 21 spectra of six black hole X-ray binaries in the hard state with data from textit{NuSTAR} and textit{Swift}. We find that 76% of the observations in […]

SPT-CL J2215-3537: A Massive Starburst at the Center of the Most Distant Relaxed Galaxy Cluster

Kavli Affiliate: Adam B. Mantz | First 5 Authors: Michael S. Calzadilla, Lindsey E. Bleem, Michael McDonald, Michael D. Gladders, Adam B. Mantz | Summary: We present the discovery of the most distant, dynamically relaxed cool core cluster, SPT-CL J2215-3537 (SPT2215) and its central brightest cluster galaxy (BCG) at z=1.16. Using new X-ray observations, we […]

Anatomy of plasmons in generic Luttinger semimetals

Kavli Affiliate: Jing Wang | First 5 Authors: Jing Wang, Ipsita Mandal, , , | Summary: We investigate the parameter regimes favourable for the emergence of plasmons in isotropic, anisotropic, and band-mass symmetric and asymmetric Luttinger semimetals (LSMs). An LSM harbours a quadratic band-crossing point (QBCP) in its bandstructure, where the upper and lower branches […]
