EPOCHS IX. When cosmic dawn breaks: Evidence for evolved stellar populations in galaxies from PEARLS GTO and public NIRCam imaging
James A. A. Trussler, Christopher J. Conselice, Nathan Adams +28
The presence of evolved stars in high-redshift galaxies can place valuable indirect constraints on the onset of star formation in the Universe. Thus we use PEARLS GTO and public NI…
Inspiraling streams of enriched gas observed around a massive galaxy 11 billion years ago
Shiwu Zhang, Zheng Cai, Dandan Xu +19
Stars form in galaxies, from gas that has been accreted from the intergalactic medium. Simulations have shown that recycling of gas-the reaccretion of gas that was previously eject…
(SHERRY) JCMT-SCUBA2 High Redshift Bright Quasar Survey -- II: the environment of z~6 quasars in sub-millimeter band

Constraining galaxy overdensities around three z~6.5 quasars with ALMA and MUSE
Romain A. Meyer, Roberto Decarli, Fabian Walter +6
We quantify galaxy overdensities around three high-redshift quasars with known [CII] 158um companions: PJ231-20 (z=6.59), PJ308-21 (z=6.24) and J0305-3150 (z=6.61). Recent SCUBA2 i…
