Kavli Affiliate: Peter F. Michelson | First 5 Authors: Pei Wang, Di Li, Colin J. Clark, Pablo Saz Parkinson, Xian Hou | Summary: High sensitivity radio searches of unassociated $gamma$-ray sources have proven to be an effective way of finding new pulsars. Using the Five-hundred-meter Aperture Spherical radio Telescope (FAST) during its commissioning phase, we […]

Kavli Affiliate: J. S. Villasenor | First 5 Authors: Fernando Barbero, Marc Basquens, Valle Varo, Eduardo J. S. Villaseñor, | Summary: The Hamiltonian description of mechanical or field models defined by singular Lagrangians plays a central role in physics. A number of methods are known for this purpose, the most popular of them being the […]
Kavli Affiliate: Daniel E. Holz | First 5 Authors: Reed Essick, Amanda Farah, Shanika Galaudage, Colm Talbot, Maya Fishbach | Summary: As catalogs of gravitational-wave transients grow, new records are set for the most extreme systems observed to date. The most massive observed black holes probe the physics of pair instability supernovae while providing clues […]
Kavli Affiliate: Masahiro Nozaki | First 5 Authors: Kanato Goto, Masahiro Nozaki, Kotaro Tamaoka, , | Summary: We introduce a subsystem generalization of the spectral form factor via pseudo entropy, the von-Neumann entropy for the reduced transition matrix. We consider a transition matrix between the thermofield double state and its time-evolved state in two-dimensional conformal […]
Kavli Affiliate: Emil J. Martinec | First 5 Authors: Bruno Balthazar, Amit Giveon, David Kutasov, Emil J. Martinec, | Summary: We propose a new $AdS_3/CFT_2$ duality, in which the bulk string theory has a target spacetime $AdS_3$ times a squashed three-sphere $S^3_flat$, and the dual $CFT_2$ is a symmetric product of sigma models on $R_phitimes […]
Kavli Affiliate: Max Tegmark | First 5 Authors: Samantha D’Alonzo, Max Tegmark, , , | Summary: We present an automated method for measuring media bias. Inferring which newspaper published a given article, based only on the frequencies with which it uses different phrases, leads to a conditional probability distribution whose analysis lets us automatically map […]
Kavli Affiliate: Eric Charles | First 5 Authors: Celine Armand, Eric Charles, Mattia di Mauro, Chiara Giuri, J. Patrick Harding | Summary: Cosmological and astrophysical observations suggest that 85% of the total matter of the Universe is made of Dark Matter (DM). However, its nature remains one of the most challenging and fundamental open questions […]
Kavli Affiliate: Yuji Tachikawa | First 5 Authors: Yuji Tachikawa, Mayuko Yamashita, , , | Summary: We reformulate the question of the absence of global anomalies of heterotic string theory mathematically in terms of a certain natural transformation $mathrm{TMF}^bulletto (I_{mathbb{Z}}Omega^text{string})^{bullet-20}$, from topological modular forms to the Anderson dual of string bordism groups, using the Segal-Stolz-Teichner […]
Kavli Affiliate: Herman L. Marshall | First 5 Authors: Herman L. Marshall, Yang Chen, Jeremy J. Drake, Matteo Guainazzi, Vinay L. Kashyap | Summary: We describe a process for cross-calibrating the effective areas of X-ray telescopes that observe common targets. The targets are not assumed to be "standard candles" in the classic sense, in that […]
