FAST discovery of an extremely radio-faint millisecond pulsar from the Fermi-LAT unassociated source 3FGL J0318.1+0252

Posted by klaurent September 2, 2021Stanford

Kavli Affiliate: Peter Michelson | Summary:High sensitivity radio searches of unassociated $γ$-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 have carried out a number of targeted deep searches of textitFermi Large Area Telescope (LAT) $γ$-ray sources. On […]

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 […]

Probing Extremal Gravitational-Wave Events with Coarse-Grained Likelihoods

Posted by klaurent September 1, 2021Chicago

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 […]

Subregion Spectrum Form Factor via Pseudo Entropy

Posted by klaurent September 1, 2021UCAS

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 […]

Asymptotically Free AdS3/CFT2

Posted by klaurent August 31, 2021Chicago

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 […]

Combined dark matter searches towards dwarf spheroidal galaxies with Fermi-LAT, HAWC, H.E.S.S., MAGIC, and VERITAS

Posted by klaurent August 31, 2021Stanford

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 […]

Concordance: In-flight Calibration of X-ray Telescopes without Absolute References

Posted by klaurent August 30, 2021MIT

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 […]

Blázquez-Salcedo-Knoll-Radu Wormholes Are Not Solutions to the Einstein-Dirac-Maxwell Equations

Posted by August 30, 2021Chicago

Kavli Affiliate: Robert M. Wald | First 5 Authors: Daine L. Danielson, Gautam Satishchandran, Robert M. Wald, Robert J. Weinbaum, | Summary: Recently, Bl’azquez-Salcedo, Knoll, and Radu (BSKR) have given a class of static, spherically symmetric, traversable wormhole spacetimes with Dirac and Maxwell fields. The BSKR wormholes are obtained by joining a classical solution to […]

Third Data Release of the Hyper Suprime-Cam Subaru Strategic Program

Posted by klaurent August 30, 2021Tokyo

Kavli Affiliate: Hiroaki Aihara | Summary:The paper presents the third data release of Hyper Suprime-Cam Subaru Strategic Program (HSC-SSP), a wide-field multi-band imaging survey with the Subaru 8.2m telescope. HSC-SSP has three survey layers (Wide, Deep, and UltraDeep) with different area coverages and depths, designed to address a wide array of astrophysical questions. This third […]
