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 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…
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…
