Predicted Capabilities of the SPRITE SmallSat for a Low-Redshift Lyman Continuum Emission Survey
Yi Hang Valerie Wong, Brian Fleming, Elena Carlson +13
Ionizing Lyman continuum (LyC; ) radiation from low-redshift () galaxies provides crucial insight into the processes that contributed to cosmi…
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…
Delayed Feedback in High- Starbursts Revealed by Lyman- Profiles and Metal Line Diagnostics
James Nianias, Jeremy Lim, Yik Lok Wong +1
Lyman- emission, which couples strongly to gas kinematics, is a key observable for probing outflows from star-forming galaxies in the early universe. Inferences of outflow prop…
Detection Rate of Fast Radio Bursts in the Milky Way with BURSTT
Decmend Fang-Jie Ling, Tetsuya Hashimoto, Shotaro Yamasaki +5
Fast radio bursts (FRBs) are intense bursts of radio emission with durations of milliseconds. Although researchers have found them happening frequently all over the sky, they are s…
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…
Can luminous Lyman alpha emitters at 5.7 and 6.6 suppress star formation?
Daryl Joe D. Santos, Tomotsugu Goto, Tetsuya Hashimoto +5
Addressing how strong UV radiation affects galaxy formation is central to understanding their evolution. The quenching of star formation via strong UV radiation (from starbursts or…
On the relation between duration and energy of non-repeating fast radio bursts: census with the CHIME data
Seong Jin Kim, Tetsuya Hashimoto, Bo Han Chen +5
A correlation between the intrinsic energy and the burst duration of non-repeating fast radio bursts (FRBs) has been reported. If it exists, the correlation can be used to estimate…
ALMA [O III] and [C II] Detections of A1689-zD1 at
Yi Hang Valerie Wong, Poya Wang, Tetsuya Hashimoto +10
A1689-zD1 is one of the most distant galaxies, discovered with the aid of gravitational lensing, providing us with an important opportunity to study galaxy formation in the very ea…
Energy functions of fast radio bursts derived from the first CHIME/FRB catalogue
Tetsuya Hashimoto, Tomotsugu Goto, Bo Han Chen +9
Fast radio bursts (FRBs) are mysterious millisecond pulses in radio, most of which originate from distant galaxies. Revealing the origin of FRBs is becoming central in astronomy. T…
Upper limits on Einstein's weak equivalence principle placed by uncertainties of dispersion measures of fast radio bursts
Tetsuya Hashimoto, Tomotsugu Goto, Daryl Joe D. Santos +7
Fast radio bursts (FRBs) are astronomical transients with millisecond timescales occurring at cosmological distances. The observed time lag between different energies of each FRB i…
Environmental Effects on AGN activity via Extinction-free Mid-Infrared Census
Daryl Joe D. Santos, Tomotsugu Goto, Seong Jin Kim +20
How does the environment affect active galactic nucleus (AGN) activity? We investigated this question in an extinction-free way, by selecting 1120 infrared galaxies in the …
A Dyson Sphere around a black hole
Tiger Yu-Yang Hsiao, Tomotsugu Goto, Tetsuya Hashimoto +8
The search for extraterrestrial intelligence (SETI) has been conducted for nearly 60 years. A Dyson Sphere, a spherical structure that surrounds a star and transports its radiative…
Subaru medium-resolution spectra of a QSO at z=6.62: Three reionization tests
Ting-Yi Lu, Tomotsugu Goto, Ji-Jia Tang +9
Investigating the Gunn-Peterson trough of high redshift quasars (QSOs) is a powerful way to reveal the cosmic reionization. As one of such attempts, we perform a series of analyses…
Millimeter-sized grains in the protostellar envelopes: where do they come from?
Yi Hang Valerie Wong, Hiroyuki Hirashita, Zhi-Yun Li
Grain growth during star formation affects the physical and chemical processes in the evolution of star-forming clouds. We investigate the origin of the millimeter (mm)-sized grain…
