Observations of SN 2017ein Reveal Shock Breakout Emission and A Massive Progenitor Star for a Type Ic Supernova
Danfeng Xiang, Xiaofeng Wang, Jun Mo +23
We present optical and ultraviolet observations of nearby type Ic supernova SN 2017ein as well as detailed analysis of its progenitor properties from both the early-time observatio…
Light curve modeling of fast-evolving supernova KSN 2015K: explosion in circumstellar matter of Super-AGB progentor
Alexey Tolstov, Ken'ichi Nomoto, Elena Sorokina +3
Recent supernova searches revealed a number of fast-evolving luminous transients. We perform radiation hydrodynamic simulations of light curves of several models of supernova from…
Type Ib/Ic supernovae: effect of nickel mixing on the early-time color evolution and implications for the progenitors
Sung-Chul Yoon, Wonseok Chun, Alexey Tolstov +2
We investigate the effect of mixing of radioactive nickel (Ni) on the early-time color evolution of Type Ib and Ic supernovae (SNe Ib/Ic) using multi-group radiation hydrody…
Cavity Optomechanics of Topological Spin Textures in Magnetic Insulators
Igor Proskurin, Alexander S. Ovchinnikov, Jun-ichiro Kishine +1
Collective dynamics of topological magnetic textures can be thought of as a massive particle moving in a magnetic pinning potential. We demonstrate that inside a cavity resonator t…
A high dust emissivity index beta for a CO-faint galaxy in a filamentary Lyman-alpha nebula at z=3.1
Yuta Kato, Yuichi Matsuda, Daisuke Iono +15
We present CO J=4-3 line and 3 mm dust continuum observations of a 100 kpc-scale filamentary Lyα nebula (SSA22 LAB18) at z=3.1 using the Atacama Large Millimeter/submillimeter Arra…
Gravity Analog Model of Non-equilibrium Thermodynamics
Noriaki Aibara, Naoaki Fujimoto, So Katagiri +4
Non-equilibrium thermodynamics of Onsager and Machlup and of Hashitsume is reformulated as a gravity analog model, in which thermodynamic variables, kinetic coefficients and genera…
Non-equilibrium thermodynamics as gauge fixing
So Katagiri
By considering a thermodynamic force as gauge field, we extend constitutive equations of Onsager's non-equilibrium thermodynamics to non-linear equations. In Onsager's non-equilibr…
Detection of the Far-infrared [O III] and Dust Emission in a Galaxy at Redshift 8.312: Early Metal Enrichment in the Heart of the Reionization Era
Yoichi Tamura, Ken Mawatari, Takuya Hashimoto +19
We present the Atacama Large Millimeter/submillimeter Array (ALMA) detection of the [O III] 88 m line and rest-frame 90 m dust continuum emission in a Y-dropout Lyman break g…
Excitation of magnon spin photocurrents in antiferromagnetic insulators
Igor Proskurin, Alexander S. Ovchinnikov, Jun-ichiro Kishine +1
In the circular photogalvanic effect, circularly polarized light can produce a direct electron photocurrent in metals and the direction of the current depends on the polarization.…
"Big Three Dragons": a z = 7.15 Lyman BreakGalaxy Detected in [OIII] 88 m, [CII] 158 m, and Dust Continuum with ALMA
Takuya Hashimoto, Akio K. Inoue, Ken Mawatari +18
We present new ALMA observations and physical properties of a Lyman Break Galaxy at z=7.15. Our target, B14-65666, has a bright ultra-violet (UV) absolute magnitude, $M_{\rm UV}\ap…
Mason's theorem with a difference radical
Katsuya Ishizaki, Risto Korhonen, Nan Li +1
Differential calculus is not a unique way to observe polynomial equations such as . We propose a way of applying difference calculus to estimate multiplicities of the roots…
CHORUS II. Subaru/HSC Determination of the Ly Luminosity Function at : Constraints on Cosmic Reionization Model Parameter
Ryohei Itoh, Masami Ouchi, Haibin Zhang +16
We present the Ly luminosity function (LF) derived from 34 Ly emitters (LAEs) at on the sky of deg, the largest sample compared to those in the literature o…
Pendulum Leptogenesis
Kazuharu Bamba, Neil D. Barrie, Akio Sugamoto +2
We propose a new non-thermal Leptogenesis mechanism that takes place during the reheating epoch, and utilizes the Ratchet mechanism. The interplay between the oscillation of the in…
Theory of magnetoelastic resonance in a mono-axial chiral helimagnet
A. A. Tereshchenko, A. S. Ovchinnikov, I. Proskurin +2
We study magnetoelastic resonance phenomena in a mono-axial chiral helimagnet belonging to hexagonal crystal class. By computing the spectrum of coupled elastic wave and spin wave,…
ALMA Deep Field in SSA22: Survey Design and Source Catalog of a 20 arcmin^2 Survey at 1.1mm
Hideki Umehata, Bunyo Hatsukade, Ian Smail +10
To search for dust-obscured star-formation activity in the early Universe, it is essential to obtain a deep and wide submillimeter/millimeter map. The advent of the Atacama Large M…
