Balmer Break Galaxy Candidates at $z \sim 6$ : a Potential View on the Star-Formation Activity at $z ≳ 14$

Ken Mawatari, Akio K. Inoue, Takuya Hashimoto +15

We search for galaxies with a strong Balmer break (Balmer Break Galaxies; BBGs) at $z \sim 6$ over a 0.41 deg $^{2}$ effective area in the COSMOS field. Based on rich imaging data, in…

Tensile deformations of the magnetic chiral soliton lattice probed by Lorentz transmission electron microscopy

G. W. Paterson, A. A. Tereshchenko, S. Nakayama +6

We consider the case of a chiral soliton lattice subjected to uniaxial elastic strain applied perpendicular to the chiral axis and derive through analytical modelling the phase dia…

Measurement theory in classical mechanics

So Katagiri

Measurement theory in classical mechanics is investigated in the formulation of classical mechanics by Koopman and von Neumann (KvN), using Hilbert space. It is shown that the clas…

Physical Characterization of an Unlensed Dusty Star-Forming Galaxy at $z = 5.85$

Caitlin M. Casey, Jorge A. Zavala, Manuel Aravena +23

We present a physical characterization of MMJ100026.36+021527.9 (a.k.a. ``MAMBO-9''), a dusty star-forming galaxy (DSFG) at $z = 5.850 \pm 0.001$ . This is the highest redshift unlensed…

Spin Parity of Spiral Galaxies I -- Corroborative Evidence for Trailing Spirals

Masanori Iye, Kenichi Tadaki, Hideya Fukumoto

Whether the spiral structure of galaxies is trailing or leading has been a subject of debate. We present a new spin parity catalog of 146 spiral galaxies that lists the following t…

A rapidly declining transient discovered with Subaru/Hyper Suprime-Cam

Nozomu Tominaga, Tomoki Morokuma, Masaomi Tanaka +14

We perform a high-cadence transient survey with Subaru Hyper Suprime-Cam (HSC), which we call the Subaru HSC survey Optimized for Optical Transients (SHOOT). We conduct HSC imaging…

Self-force effects on the marginally bound zoom-whirl orbit in Schwarzschild spacetime

Leor Barack, Marta Colleoni, Thibault Damour +2

For a Schwarzchild black hole of mass $M$ , we consider a test particle falling from rest at infinity and becoming trapped, at late time, on the unstable circular orbit of radius $r…

A Radio-to-millimeter Census of Star-forming Galaxies in Protocluster 4C~23.56 at z = 2.5 : Global and local gas kinematics

Minju M. Lee, Ichi Tanaka, Ryohei Kawabe +12

We present a study of the gas kinematics of star-forming galaxies associated with protocluster 4C 23.56 at $z = 2.49$ using $0^{''} .4$ resolution CO (4-3) data taken with ALMA. Eleven H…

Beyond Squeezing à la Virasoro Algebra

So Katagiri, Akio Sugamoto, Koichiro Yamaguchi +1

The generalization of squeezing is realized in terms of the Virasoro algebra. The higher-order squeezing can be introduced through the higher-order time-dependent potential, in whi…

Binomial series and complex difference equations

Katsuya Ishizaki, Zhi-Tao Wen

We consider properties of binomial series $\sum_{n = 0}^{\infty} a_{n} z^{n}$ , where $z^{n} = z (z - 1) \dots (z - n + 1)$ and the convergence of binomial series in the com…

SILVERRUSH. IX. Lya Intensity Mapping with Star-Forming Galaxies at z=5.7 and 6.6: A Possible Detection of Extended Lya Emission at $≳$ 100 comoving kpc around and beyond the Virial-Radius Scale of Galaxy Dark Matter Halos

Ryota Kakuma, Masami Ouchi, Yuichi Harikane +11

We present results of the cross-correlation Ly $α$ intensity mapping with Subaru/Hyper Suprime-Cam (HSC) ultra-deep narrowband images and Ly $α$ emitters (LAEs) at $z = 5.7$ and $6.6$ …

CHORUS. III. Photometric and Spectroscopic Properties of Ly $α$ Blobs at $z = 4.9 - 7.0$

Haibin Zhang, Masami Ouchi, Ryohei Itoh +20

We report the Subaru Hyper Suprime-Cam (HSC) discovery of two Ly $α$ blobs (LABs), dubbed z70-1 and z49-1 at $z = 6.965$ and $z = 4.888$ respectively, that are Ly $α$ emitters with a bri…

Theory of standing spin waves in finite-size chiral spin soliton lattice

J. Kishine, Vl. E. Sinitsyn, I. G. Bostrem +4

We present a theory of standing spin wave (SSW) in a monoaxial chiral helimagnet. Motivated by experimental findings on the magnetic field-dependence of the resonance frequency in…
