Errors When Constraining Hot Blackbody Parameters with Optical Photometry
Iair Arcavi
Measuring blackbody parameters for objects hotter than a few 10^4K with optical data alone is common in many astrophysical studies. However this process is prone to large errors be…
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-…
The Correlation Calibration of PAPER-64 data
Tamirat G. Gogo, Yin-Zhe Ma, Piyanat Kittiwisit +21
Observation of redshifted 21-cm signal from the Epoch of Reionization (EoR) is challenging due to contamination from the bright foreground sources that exceed the signal by several…
