A Balloon-Borne Very Long Baseline Interferometry Experiment in the Stratosphere: Systems Design and Developments
Akihiro Doi, Yusuke Kono, Kimihiro Kimura +33
The balloon-borne very long baseline interferometry (VLBI) experiment is a technical feasibility study for performing radio interferometry in the stratosphere. The flight model has…
Classical and quantum cosmology of -essentially modified and pure gravity
Nahomi Kan, Kiyoshi Shiraishi, Mai Yashiki
We present a gravitational action with a modified higher order term of a combination of scalar curvature and Lagrangian density of a scalar field. This type of models has been cons…
Parabolic Jets from the Spinning Black Hole in M87
Masanori Nakamura, Keiichi Asada, Kazuhiro Hada +18
The M87 jet is extensively examined by utilizing general relativistic magnetohydrodynamic (GRMHD) simulations as well as the steady axisymmetric force-free electrodynamic (FFE) sol…
Phenomenological Consequences of the Refined Swampland Conjecture
Hajime Fukuda, Ryo Saito, Satoshi Shirai +1
We discuss phenomenological consequences of the recently-introduced refinements of the de Sitter swampland conjecture. The conjecture constraints the first and the second derivativ…
Linearized Analysis of Barotropic Perturbations around Spherically Symmetric Gaseous Stars Governed by the Euler-Poisson Equations
Juhi Jang, Tetu Makino
The hydrodynamic evolution of self-gravitating gaseous stars is governed by the Euler-Poisson equations. We study the structure of the linear approximation of barotropic perturbati…
Dynamic Fano resonances: From toy model to resonant Mie scattering
Michael I. Tribelsky, Andrey E. Miroshnichenko
Based on the substantial difference in the response time for the resonant and background partitions at stepwise variations of the exiting signal, a simple exactly integrable model…
