The CosmoVerse White Paper: Addressing observational tensions in cosmology with systematics and fundamental physics

Posted by dbos Tokyo

Kavli Affiliate: Masahiro Takada | First 5 Authors: Eleonora Di Valentino, Jackson Levi Said, Adam Riess, Agnieszka Pollo, Vivian Poulin | Summary: The standard model of cosmology has provided a good phenomenological description of a wide range of observations both at astrophysical and cosmological scales for several decades. This concordance model is constructed by a […]

The Receding Cosmic Shoreline of Mid-to-Late M Dwarfs: Measurements of Active Lifetimes Worsen Challenges for Atmosphere Retention by Rocky Exoplanets

Posted by dbos MIT

Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Emily K Pass, David Charbonneau, Andrew Vanderburg, , | Summary: Detecting and characterizing the atmospheres of terrestrial exoplanets is a key goal of exoplanetary astronomy, one that may now be within reach given the upcoming campaign to conduct a large-scale survey of rocky M-dwarf worlds with the […]

Fault-tolerant correction-ready encoding of the [[7,1,3]] Steane code on a 2D grid

Posted by dbos Berkeley

Kavli Affiliate: Birgitta Whaley | First 5 Authors: Andrea Rodriguez-Blanco, Ho Nam Nguyen, K. Birgitta Whaley, , | Summary: Practical quantum computation heavily relies on the ability to perform quantum error correction in a fault-tolerant manner. Fault-tolerant encoding is a critical first step, and careful consideration of the error correction cycle that follows is essential […]

Formation and Environmental Context of Giant Bulgeless Disk Galaxies in the Early Universe: Insights from Cosmological Simulations

Posted by dbos Peking

Kavli Affiliate: Yingjie Peng | First 5 Authors: Fangzhou Jiang, Jinning Liang, Bingcheng Jin, Zeyu Gao, Weichen Wang | Summary: Giant bulgeless disk galaxies, theoretically expected to be rare in the early Universe, have been confirmed by the James Webb Space Telescope (JWST) to exist as early as 2 billion years after the Big Bang. […]

Identifying biases of the Majorana scattering invariant

Posted by dbos Delft

Kavli Affiliate: Michael Wimmer | First 5 Authors: Isidora Araya Day, Antonio L. R. Manesco, Michael Wimmer, Anton R. Akhmerov, | Summary: The easily accessible experimental signatures of Majorana modes are ambiguous and only probe topology indirectly: for example, quasi-Majorana states mimic most properties of Majoranas. Establishing a correspondence between an experiment and a theoretical […]

Polarization Position Angle Swing and the Rotating Vector Model of Repeating Fast Radio Bursts

Posted by dbos Peking

Kavli Affiliate: Kejia Lee | First 5 Authors: Xiaohui Liu, Heng Xu, Jiarui Niu, Yongkun Zhang, Jinchen Jiang | Summary: Fast radio bursts (FRBs), typically highly polarized, usually have a nearly constant polarization position angle (PA) during each burst. Some bursts show significant PA variations, and one of them was claimed to have a PA […]

Constraints on Non-Thermal Pressure at galaxy cluster outskirts from a Joint SPT and XMM-Newton Analysis

Posted by dbos MIT

Kavli Affiliate: Catherine E. Grant | First 5 Authors: Arnab Sarkar, Michael McDonald, Lindsey Bleem, Mark Bautz, Bradford A. Benson | Summary: We present joint South Pole Telescope (SPT) and XMM-Newton observations of 8 massive galaxy clusters (0.8–1.7$times$10$^{15}$ M$_{odot}$) spanning a redshift range of 0.16 to 0.35. Employing a novel SZ+X-ray fitting technique, we effectively […]
