Point-like and Narrow-lined: A Potentially New Population of Objects Discovered by JWST
Haojing Yan, Bangzheng Sun, Riley Shive
We report a potentially new population of objects revealed by the data from the James Webb Space Telescope, which are characterized by their point-like morphology and narrow permit…
New Insight from the James Webb Space Telescope on Variable Active Galactic Nuclei
Bangzheng Sun, Haojing Yan, Wei Leong Tee +1
Variability detected in galaxies is usually attributed to their active galactic nuclei (AGNs). While all AGNs are intrinsically variable, the AGN unification model predicts that ty…
PEARLS: 21 Transients Found in the Three-Epoch NIRCam Observations in the Continuous Viewing Zone of the James Webb Space Telescope
Haojing Yan, Bangzheng Sun, Zhiyuan Ma +39
We present 21 transients from our three-epoch, four-band NIRCam observations covering 14.16 arcmin^2 in the Spitzer IRAC Dark Field (IDF), taken by the JWST Prime Extragalactic Are…
Constraining the z 1 Initial Mass Function with {\it HST} and {\it JWST} Lensed Stars in MACS J0416.1-2403
Sung Kei Li, Jose M. Diego, Ashish K. Meena +19
Our understanding of galaxy properties and evolution is contingent on knowing the initial mass function (IMF), and yet to date, the IMF is constrained only to local galaxies. Indiv…
A Mysteriously Tight H-[O III] Correlation and Non-Case B Balmer Decrements Revealed by the Spectra from the James Webb Space Telescope NIRSpec Instrument
Bangzheng Sun, Haojing Yan
We report an extremely tight, linear relation between and [O~III] line fluxes in logarithm, discovered using a large sample of low and mid-resolution spectra (totaling 5…
On The Very Bright Dropouts Selected Using the James Webb Space Telescope NIRCam Instrument
Bangzheng Sun, Haojing Yan
The selection of candidate high-redshift galaxies using the dropout technique targeting the Lyman-break signature sometimes yields very bright objects that are too luminous to be e…
