Supermassive Primordial Black Holes From Inflation

Kavli Affiliate: Albert Stebbins | First 5 Authors: Dan Hooper, Aurora Ireland, Gordan Krnjaic, Albert Stebbins, | Summary: There is controversy surrounding the origin and evolution of our universe’s largest supermassive black holes (SMBHs). In this study, we consider the possibility that some of these black holes formed from the direct collapse of primordial density […]

IXPE and multi-wavelength observations of blazar PG 1553+113 reveal an orphan optical polarization swing

Kavli Affiliate: Herman L. Marshall | First 5 Authors: Riccardo Middei, Matteo Perri, Simonetta Puccetti, Ioannis Liodakis, Laura Di Gesu | Summary: The lower energy peak of the spectral energy distribution of blazars has commonly been ascribed to synchrotron radiation from relativistic particles in the jets. Despite the consensus regarding jet emission processes, the particle […]

Poly-MOT: A Polyhedral Framework For 3D Multi-Object Tracking

Kavli Affiliate: Ke Wang | First 5 Authors: Xiaoyu Li, Tao Xie, Dedong Liu, Jinghan Gao, Kun Dai | Summary: 3D Multi-object tracking (MOT) empowers mobile robots to accomplish well-informed motion planning and navigation tasks by providing motion trajectories of surrounding objects. However, existing 3D MOT methods typically employ a single similarity metric and physical […]

Note on generating operators of symmetry breaking operators — from discrete to continuous

Kavli Affiliate: Toshiyuki Kobayashi | First 5 Authors: Toshiyuki Kobayashi, , , , | Summary: Via the "generating operator" of the Rankin-Cohen brackets introduced in Kobayashi–Pevzner [arXiv:2306.16800], we present a trick to produce various non-local intertwining operators with continuous parameter out of a countable set of differential symmetry breaking operators. | Search Query: ArXiv Query: […]
