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…
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…
Finding dusty AGNs from the JWST CEERS survey with mid-infrared photometry
Tom C. -C. Chien, Chih-Teng Ling, Tomotsugu Goto +8
The nature of the interaction between active galactic nuclei (AGNs) and their host galaxies remains an unsolved question. Therefore, conducting an AGN census is valuable to AGN res…
Exploring the faintest end of mid-infrared luminosity functions up to with the JWST CEERS survey
Chih-Teng Ling, Tomotsugu Goto, Seong Jin Kim +6
Mid-infrared (MIR) light from galaxies is sensitive to dust-obscured star-formation activities because it traces the characteristic emission of dust heated by young, massive stars.…
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…
A T-Dwarf Candidate from JWST Early Release NIRCam data
Po-Ya Wang, Tomotsugu Goto, Simon C. -C. Ho +6
We present a distant Ttype brown dwarf candidate at kpc discovered in the Cosmic Evolution Early Release Science (CEERS) fields by James Webb Space Telescope (JWST…
Galaxy source counts at 7.7 m, 10 m and 15 m with the James Webb Space Telescope
Chih-Teng Ling, Seong Jin Kim, Cossas K. -W. Wu +7
We present mid-infrared galaxy number counts based on the Early Release Observations obtained by the James Webb Space Telescope (JWST) at 7.7-, 10- and 15-m (F770W, F1000W and F…
Constraining the Hubble constant and its lower limit from the proper motion of extragalactic radio jets
Tiger Yu-Yang Hsiao, Tomotsugu Goto, Tetsuya Hashimoto +11
The Hubble constant () is a measurement to describe the expansion rate of the Universe in the current era. However, there is a discrepancy between the measurements fr…
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-…
