A Diverse Population of z ~ 2 ULIRGs Revealed by JWST Imaging

Autor: Huang, J. -S., Li, Zi-Jian, Cheng, Cheng, Hou, Meicun, Yan, Haojing, Willner, S. P., Dai, Y. -S., Zheng, X. Z., Pan, J., Rigopoulou, D., Wang, T., Li, Zhiyuan, Liang, Piaoran, Esamdin, A., Fazio, G. G.

Four ultra-luminous infrared galaxies (ULIRGs) observed with JWST/NIRcam in the Cosmos Evolution Early Release Science program offer an unbiased preview of the $z\approx2$ ULIRG population. The objects were originally selected at 24 $\mu$m and have s

We report the time-resolved spectral analysis of a bright near-infrared and moderate X-ray flare of Sgr A*. We obtained light curves in the $M$-, $K$-, and $H$-bands in the mid- and near-infrared and in the $2-8~\mathrm{keV}$ and $2-70~\mathrm{keV}$

A Complete 16 micron-Selected Galaxy Sample at $z\sim1$: Mid-infrared Spectral Energy Distributions

We describe a complete, flux-density-limited sample of galaxies at redshift $0.8 < z < 1.3$ selected at 16 micron. At the selection wavelength near 8 micron rest, the observed emission comes both from dust heated by intense star formation and from ac

Rapid Variability of Sgr A* across the Electromagnetic Spectrum

Sagittarius A* (Sgr A*) is the variable radio, near-infrared (NIR), and X-ray source associated with accretion onto the Galactic center black hole. We have analyzed a comprehensive submillimeter (including new observations simultaneous with NIR monit
