Kavli Affiliate: John E. Carlstrom | First 5 Authors: Kaushik Satapathy, Dimitrios Psaltis, Feryal Ozel, Lia Medeiros, Sean T. Dougall | Summary: The black-hole images obtained with the Event Horizon Telescope (EHT) are expected to be variable at the dynamical timescale near their horizons. For the black hole at the center of the M87 galaxy, […]
Kavli Affiliate: Roland K. Vanderspek | First 5 Authors: Christina Hedges, Alex Hughes, Steven Giacalone, George Zhou, Trevor J. David | Summary: We report the discovery of two planetary systems around comoving stars; TOI-2076 (TIC 27491137) and TOI-1807 (TIC 180695581). TOI-2076 is a nearby (41.9 pc) multi-planetary system orbiting a young (204$pm$50 Myr), bright (K […]
Kavli Affiliate: Xiang Zhang | First 5 Authors: Changhao Wang, Zhian Kuang, Xiang Zhang, Masayoshi Tomizuka, | Summary: Smooth behaviors are preferable for many contact-rich manipulation tasks. Impedance control arises as an effective way to regulate robot movements by mimicking a mass-spring-damping system. Consequently, the robot behavior can be determined by the impedance gains. However, […]
Kavli Affiliate: Jia Liu | First 5 Authors: Jinhui Guo, Yuxuan He, Jia Liu, Xiao-Ping Wang, | Summary: The coannihilation mechanism is a well-motivated alternative to the simple thermal freeze-out mechanism, where the dark matter relic density can be obtained through the coannihilation with a partner particle of similar mass with dark matter. When the […]
Kavli Affiliate: C. L. Kuo | First 5 Authors: J. S. -Y. Leung, J. Hartley, J. M. Nagy, C. B. Netterfield, J. A. Shariff | Summary: Modern CMB analysis pipelines regularly employ complex time-domain filters, beam models, masking, and other techniques during the production of sky maps and their corresponding angular power spectra. However, these […]
Kavli Affiliate: Misao Sasaki | First 5 Authors: Pisin Chen, Misao Sasaki, Dong-han Yeom, Junggi Yoon, | Summary: The information loss paradox associated with black hole Hawking evaporation is an unresolved problem in modern theoretical physics. In this paper, we revisit the entanglement entropy via the Euclidean path integral (EPI) of the quantum state and […]
Kavli Affiliate: Ke Wang | First 5 Authors: Ke Wang, , , , | Summary: For a distorted black hole (BH), its ringdown waveform is a superposition of quasi-normal modes (QNMs). In general relativity (GR), the lower order QNM frequencies and damping rates can be well approximated by a polynomial of BH’s dimensionless spin and […]
Kavli Affiliate: T. Higuchi | First 5 Authors: Belle II Collaboration, F. Abudinén, I. Adachi, R. Adak, K. Adamczyk | Summary: We present a reconstruction in early data of the semileptonic decay $B^+ to pi^0 ell^+ nu_ell$, and first results of a reconstruction of the decays $B^+ to rho^0 ell^+ nu_ell$ and $B^0 to rho^- […]

Farinelli, Abigail Sullivan, Tarun N. Bhatia, Hannah Yankello, Rohan Reddy, Younsoo Bae, Rehana K Leak, Sruti Shiva, Louise D McCullough and Devika Soundara Manickam | […]
Kavli Affiliate: Alexander P. Ji | First 5 Authors: Sal Wanying Fu, Daniel R. Weisz, Else Starkenburg, Nicolas Martin, Alexander P. Ji | Summary: We use deep narrowband Ca H&K ($F395N$) imaging taken with the Hubble Space Telescope (HST) to construct the metallicity distribution function (MDF) of Local Group (LG) ultra-faint dwarf (UFD) galaxy Eridanus […]
