A Promising New Dark Matter Candidate, and Implications for the Search for Extraterrestrial Intelligence (SETI)

Autor: Prillfool, A., Stoffers, A. A., Juodžbalis, I., Bothwell, M. S., Wojcik, A. J.

We present a speculative exploration of the properties of a proposed new Dark Matter (DM) candidate in a heretofore under-explored region of parameter space. Our proposed ultra-cold candidatae has been a matter of speculation for some time,and has re

Discovery and properties of ultra-high redshift galaxies ($9

Autor: Adams, N. J., Conselice, C. J., Ferreira, L., Austin, D., Trussler, J., Juodžbalis, I., Wilkins, S. M., Caruana, J., Dayal, P., Verma, A., Vijayan, A. P.

We present a reduction and analysis of the \textit{James Webb Space Telescope} (JWST) SMACS~0723 field using new post-launch calibrations to conduct a search for ultra-high-redshift galaxies ($z > 9$) present within the Epoch of Reionisation. We cond
