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…
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…
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…
Machine learning based Photometric Redshifts for Galaxies in the North Ecliptic Pole Wide field: catalogs of spectroscopic and photometric redshifts
Taewan Kim, Jubee Sohn, Ho Seong Hwang +13
We perform an MMT/Hectospec redshift survey of the North Ecliptic Pole Wide (NEPW) field covering 5.4 square degrees, and use it to estimate the photometric redshifts for the sourc…
