Two lensed star candidates at behind the galaxy cluster MACS J0647.7+7015
Ashish Kumar Meena, Adi Zitrin, Yolanda Jiménez-Teja +24
We report the discovery of two extremely magnified lensed star candidates behind the galaxy cluster MACS J0647.7+7015, in recent multi-band James Webb Space Telescope (JWST) NIRCam…
JWST/NIRCam Probes Young Star Clusters in the Reionization Era Sunrise Arc
E. Vanzella, A. Claeyssens, B. Welch +27
Star cluster formation in the early universe and their contribution to reionization remains to date largely unconstrained. Here we present JWST/NIRCam imaging of the most highly ma…
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…
JWST reveals a possible galaxy merger in triply-lensed MACS0647JD
Tiger Yu-Yang Hsiao, Dan Coe, Abdurro'uf +63
MACS0647JD is a triply-lensed galaxy originally discovered with the Hubble Space Telescope. Here we report new JWST imaging, which clearly resolves MACS0647JD as ha…
High-Redshift Galaxy Candidates at as Revealed by JWST Observations of WHL0137-08
Larry D. Bradley, Dan Coe, Gabriel Brammer +25
We report the discovery of four galaxy candidates observed 450 - 600 Myr after the Big Bang with photometric redshifts between z ~ 8.3 - 10.2 measured using the JWST NIRCam imaging…
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…
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…
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…
JWST Imaging of Earendel, the Extremely Magnified Star at Redshift
Brian Welch, Dan Coe, Erik Zackrisson +60
The gravitationally lensed star WHL0137-LS, nicknamed Earendel, was identified with a photometric redshift based on images taken with the Hubble Space Tele…
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…
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-…
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…
