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…
Mid-IR luminosity functions: inferred dusty cosmic star-formation and black hole accretion histories from the JWST SMILES
Chih-Teng Ling, Tomotsugu Goto, Seong Jin Kim +5
Mid-infrared (mid-IR) observations are crucial for understanding galaxy evolution, tracing star formation, and active galactic nuclei (AGN) activity via dust emission. This work pr…
JWST MIRI color classification of mid-infrared selected galaxies: MIRI color classification toward cosmic noon
Ece Kilerci, Tomotsugu Goto, Matthew A. Malkan +7
We investigated the James Webb Space Telescope photometric color classification of mid-infrared (MIR) selected galaxies at high redshifts, toward cosmic noon. The aim of the presen…
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…
Inferring Obscured Cosmic Black Hole Accretion History from AGN Found by JWST/MIRI CEERS Survey
Cheng-An Hsieh, Tomotsugu Goto, Chih-Teng Ling +4
This study presents the black hole accretion history (BHAH) of obscured active galactic nuclei (AGNs) identified from the JWST CEERS survey by Chien et al. (2024) using mid-infrare…
All-sky search for individual Primordial Black Hole bursts with LHAASO
Zhen Cao, F. Aharonian, Y. X. Bai +311
Primordial Black Holes~(PBHs) are hypothetical black holes with a wide range of masses that formed in the early universe. As a result, they may play an important cosmological role…
A Search for Planet Nine with IRAS and AKARI Data
Terry Long Phan, Tomotsugu Goto, Issei Yamamura +6
The outer solar system is theoretically predicted to harbour an undiscovered planet, often referred to as P9. Simulations suggest that its gravitational influence could explain the…
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…
