Reconstruction of the Weyl-Lewis-Papapetrou metric for stationary and axially symmetric gravitational perturbations of a Kerr black hole
David Kofroň, Petr Kotlařík
The study of black hole perturbations typically follows two main approaches: the direct perturbation of the metric, or the perturbation within the Newman-Penrose (NP) or Geroch-Hel…
Multimessenger Characterization of High-Energy Neutrino Emission from the Brightest Neutrino-Active Galactic Nuclei
Jose Alonso Carpio, Ali Kheirandish, Kohta Murase
The observation of high-energy neutrinos from the direction of the nearby active galaxy, NGC 1068, was a major step in identifying the origin of high-energy cosmic neutrinos. The m…
The emergent Big Bang scenario
Justin C. Feng, Shinji Mukohyama, Jean-Philippe Uzan
This paper proposes a new avenue for understanding the cosmological singularity. The standard cosmological model contains a generic initial singularity usually referred to as the {…
Non-invertible translation from Lieb-Schultz-Mattis anomaly
Tsubasa Oishi, Takuma Saito, Hiromi Ebisu
Symmetry provides powerful non-perturbative constraints in quantum many-body systems. A prominent example is the Lieb-Schultz-Mattis (LSM) anomaly -- a mixed 't Hooft anomaly betwe…
Constraining the inflaton potential with gravitational waves from oscillons
Kaloian D. Lozanov, Misao Sasaki, Jan Tränkle
Under certain conditions, the oscillating inflaton condensate filling the Universe after inflation can fragment and form so-called oscillons. These long-lived soliton-like field co…
Little Red Dots as Hidden Neutrino Sources
Riku Kuze, Kunihito Ioka, Kohta Murase +2
Little Red Dots (LRDs) are enigmatic, compact, red galaxies at high redshift, -, discovered by the James Webb Space Telescope. Broad emission lines in the absence of X-…
