Model-based cross-correlation search for gravitational waves from the low-mass X-ray binary Scorpius X-1 in LIGO O3 data
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1692
We present the results of a model-based search for continuous gravitational waves from the low-mass X-ray binary Scorpius X-1 using LIGO detector data from the third observing run…
Training Process of Unsupervised Learning Architecture for Gravity Spy Dataset
Yusuke Sakai, Yousuke Itoh, Piljong Jung +11
Transient noise appearing in the data from gravitational-wave detectors frequently causes problems, such as instability of the detectors and overlapping or mimicking gravitational-…
Self-mixing interference in a thin-slice solid-state laser with few feedback photons per observation period
Kenju Otsuka, Seiichi Sudo
Formation of a peculiar lasing pattern leading to a TEM00-like mode accompanied by a nonzero bright outer-ring emission (namely, a modified TEM00 mode) was observed in a 300-μm-thi…
Detection of an extremely large impact flash on Jupiter by high-cadence multiwavelength observations
Ko Arimatsu, Kohji Tsumura, Fumihiko Usui +1
We report the detection of an optical impact flash on Jupiter on 15 October 2021 by a dedicated telescope, Planetary ObservatioN Camera for Optical Transient Surveys (PONCOTS), for…
First High-speed Video Camera Observations of a Lightning Flash Associated with a Downward Terrestrial Gamma-ray Flash
R. U. Abbasi, M. M. F. Saba, J. W. Belz +146
In this paper, we present the first high-speed video observation of a cloud-to-ground lightning flash and its associated downward-directed Terrestrial Gamma-ray Flash (TGF). The op…
Thermodynamics and hydrodynamics of spontaneous and forced imbibition in conical capillaries: A theoretical study of conical liquid diode
Masao Iwamatsu
Thermodynamics and hydrodynamics of spontaneous and forced imbibition of liquid into conical capillaries are studied to assess the feasibility of a conical liquid diode. The analyt…
