ALMA and NOEMA constraints on synchrotron nebular emission from embryonic superluminous supernova remnants and radio-gamma-ray connection
Kohta Murase, Conor M. B. Omand, Deanne L. Coppejans +8
Fast-rotating pulsars and magnetars have been suggested as the central engines of super-luminous supernovae (SLSNe) and fast radio bursts, and this scenario naturally predicts non-…
Multi-wavelength View of the Type IIn Zoo: Optical to X-ray Emission Model of Interaction-Powered Supernovae
Daichi Tsuna, Kazumi Kashiyama, Toshikazu Shigeyama
Transients powered by interaction with the circumstellar medium (CSM) are often observed in wavelengths other than optical, and multi-wavelength modelling can be important when inf…
Gravitational wave backgrounds from coalescing black hole binaries at cosmic dawn: an upper bound
Kohei Inayoshi, Kazumi Kashiyama, Eli Visbal +1
The successive discoveries of binary merger events by Advanced LIGO-Virgo have been revealing the statistical properties of binary black hole (BBH) populations. A stochastic gravit…
A necessary condition for supernova fallback invading newborn neutron-star magnetosphere
Yici Zhong, Kazumi Kashiyama, Toshikazu Shigeyama +1
We numerically investigate the dynamics of a supernova fallback accretion confronting with a relativistic wind from a newborn neutron star (NS). The time evolution of the accretion…
Intermediate Luminosity Red Transients by Black Holes Born from Erupting Massive Stars
Daichi Tsuna, Ayako Ishii, Naoto Kuriyama +2
We consider black hole formation in failed supernovae when a dense circumstellar medium (CSM) is present around the massive star progenitor. By utilizing radiation hydrodynamical s…
Astrometric study of Gaia DR2 stars for interstellar communication
Naoki Seto, Kazumi Kashiyama
We discuss the prospects of high precision pointing of our transmitter to habitable planets around Galactic main sequence stars. For an efficient signal delivery, the future sky po…
