Statistical inference of fast radio burst environments using galaxy number density
Vignesh V. V. Rao, Tetsuya Hashimoto, Tomotsugu Goto +9
Fast radio bursts (FRBs) are bright, millisecond-duration radio transients of unknown origin. They are categorized as repeaters and non-repeaters, possibly indicating distinct prog…
The Search for Technosignatures: a Review of Possibilities
Clément Vidal, Benji L. Fields, Damian R. Sowinski +19
This paper reviews the diverse range of technosignatures that have been proposed in the literature. We organize the review by spatial scales from the Earth and the solar system to…
Photometrically Selected Protocluster Candidates at z~9-10 in the JWST COSMOS-Web field
Cossas K. -W. Wu, Chih-Teng Ling, Tomotsugu Goto +8
High-redshift protoclusters are crucial for understanding the formation of galaxy clusters and the evolution of galaxies in dense environments. The James Webb Space Telescope (JWST…
A Far-Infrared Search for Planet Nine Using AKARI All-Sky Survey
Amos Y. -A. Chen, Tomotsugu Goto, Issei Yamamura +7
An unusual orbital element clustering of Kuiper belt objects (KBOs) has been observed. The most promising dynamic solution is the presence of a giant planet in the outer Solar syst…
Do they repeat? Monitoring 36 non-repeating FRBs with FAST
Yuri Uno, Tetsuya Hashimoto, Tomotsugu Goto +12
The origin of fast radio bursts (FRBs), highly energetic, millisecond-duration radio pulses originating from beyond our galaxy, remains unknown. Observationally, FRBs are classifie…
No detection of radio continuum from low-redshift passive spiral galaxies
Hei Yung Chan, Michael J. I. Brown
Radio-emitting active galactic nuclei (AGNs) are common in elliptical galaxies and AGN feedback is one of the possible mechanisms for regulating star formation in massive galaxies.…
Brown dwarf number density in the JWST COSMOS-Web field
Amos Y. -A. Chen, Tomotsugu Goto, Cossas K. -W. Wu +9
Brown dwarfs are failed stars with very low mass (13 to 75 ), and an effective temperature lower than 2500 K. Thus, they play a key role in understanding the gap in the mass f…
Polycyclic aromatic hydrocarbon (PAH) luminous galaxies in JWST CEERS data
Yu-Wei Lin, Cossas K. -W. Wu, Chih-Teng Ling +9
It has been an unanswered question how many dusty galaxies have been undetected from the state-of-the-art observational surveys. JWST enables us to detect faint IR galaxies that ha…
Cosmic star-formation history and black hole accretion history inferred from the JWST mid-infrared source counts
Seong Jin Kim, Tomotsugu Goto, Chih-Teng Ling +7
With the advent of the James Webb Space Telescope (JWST), extra-galactic source count studies were conducted down to sub-microJy in the mid-infrared (MIR), which is several tens of…
Machine Learning Classification of Repeating FRBs from FRB121102
Bjorn Jasper R. Raquel, Tetsuya Hashimoto, Tomotsugu Goto +5
Fast Radio Bursts (FRBs) are mysterious bursts in the millisecond timescale at radio wavelengths. Currently, there is little understanding about the classification of repeating FRB…
A Keplerian disk with a four-arm spiral birthing an episodically accreting high-mass protostar
R. A. Burns, Y. Uno, N. Sakai +34
High-mass protostars (M 8 M) are thought to gain the majority of their mass via short, intense bursts of growth. This episodic accretion is thought to be faci…
Future Constraints on Dark Matter with Gravitationally Lensed Fast Radio Bursts Detected by BURSTT
Simon C. -C. Ho, Tetsuya Hashimoto, Tomotsugu Goto +4
Understanding dark matter is one of the most urgent questions in modern physics. A very interesting candidate is primordial black holes (PBHs; Carr2016). For the mass ranges of $<…
Upper limits on transmitter rate of extragalactic civilizations placed by Breakthrough Listen observations
Yuri Uno, Tetsuya Hashimoto, Tomotsugu Goto +3
The Search for Extra-Terrestrial Intelligence (SETI) has been conducted for over sixty years, yet no technosignatures have been identified. Previous studies have focused on stars i…
Classifying a frequently repeating fast radio burst, FRB 20201124A, with unsupervised machine learning
Bo Han Chen, Tetsuya Hashimoto, Tomotsugu Goto +5
Fast radio bursts (FRBs) are astronomical transients with millisecond timescales. Although most of the FRBs are not observed to repeat, a few of them are detected to repeat more th…
The molecular gas kinematics in the host galaxy of non-repeating FRB 180924B
Tzu-Yin Hsu, Tetsuya Hashimoto, Bunyo Hatsukade +5
Fast radio bursts (FRBs) are millisecond-duration transients with large dispersion measures. The origin of FRBs is still mysterious. One of the methods to comprehend FRB origin is…
Source counts at 7.7 to 21 m in CEERS field with James Webb Space Telescope
Cossas K. -W. Wu, Chih-Teng Ling, Tomotsugu Goto +8
Source counts -- the number density of sources as a function of flux density -- represent one of the fundamental metrics in observational cosmology due to their straightforward and…
BURSTT: Bustling Universe Radio Survey Telescope in Taiwan
Hsiu-Hsien Lin, Kai-yang Lin, Chao-Te Li +44
Fast Radio Bursts (FRBs) are bright millisecond-duration radio transients that appear about 1,000 times per day, all-sky, for a fluence threshold 5 Jy ms at 600 MHz. The FRB radio-…
